Historic Chocolate Works preserved with Sika Sarnafil

Eight years after being put on the ‘At Risk’ register by English Heritage, the landmark Terry’s Chocolate Factory has a new lease of life, following extensive refurbishment. The 1926, Grade II listed building now starts a new chapter as a care village owned by Springfield Healthcare.

Once home to famous brands such as Chocolate Orange, the factory and offices were closed in 2005 and fell into disrepair over the subsequent decade. Eventually the building, which is part of a 27-acre site, was acquired by Henry Boot Developments for conversion. The renovations included a full roof refurbishment that was undertaken by Hull-based roofing contractor L.A. Hall using a Sika Sarnafil single ply system.

One of the key focuses of the work was to preserve and retain the art deco features of the building while increasing its lifespan. A vital element of the repairs was the work on the existing flat and slate roof areas that were in a very poor state, and a roof for the new additional floor of the building.

Principal contractor Simpson (York) Ltd., brought L.A. Hall on board to complete the roofing works, which comprised a number of disciplines, including heritage Westmorland slating, single ply, zinc cladding and leadwork.

L.A. Hall suggested using a Sika Sarnafil system for the flat roof areas, as it matched the client’s requirements for longevity and sustainability, and is the company’s preferred membrane choice. The project’s conservation officer was initially concerned that the system would be too shiny, but Sika Sarnafil provided a number of samples, and after discussions, the specification was welcomed by all parties.

The project was complex due to the multiple roof areas and detailing. To begin, the existing slating on the central north light roof slopes, which were remaining in place as part of the new scheme, were re-covered using a fully adhered Sika Sarnafil system including G410-EL membrane in Lead Grey.

In addition to the existing roof areas, an extra floor to the building was constructed around the north lights. Its steep slated mansard-type external elevation included approximately 60 dormer windows, which required zinc on all the vertical faces and Sarnafil on the tops. The flat roof area of the extension was then also covered in the Sarnafil system, along with 140m of parapet guttering detailing, and a new roof terrace area.

Nigel Drysdale, Technical Advisor at Sika Sarnafil said “We had a great number of details to consider in order to preserve the original look of the building. For example, the architect and conservation officer required a timber mop roll detail to the perimeter of the main roof and the dormers. So all the parties worked closely to achieve a practical and aesthetic solution, which involved creating detailed life-sized models of key elements. This collaborative and applied approach gave the conservation officer confidence that the detailing was sympathetic to the building’s heritage and that’s what we eventually installed.”

The L.A. Hall team overcame various challenges, including working on sloped areas, tight time scales and challenging winter weather, but thanks to the skill of the fitters and the flexibility of the Sarnafil system, the project was finished to an impeccable standard and on time.

All members on the team agree that the newly refurbished roof looks stunning and will defend this iconic building from the elements for many years to come.

Brookhurst handmade clay roof tiles for Suffolk new build and renovation

Brookhurst handmade clay roof tiles have been specified for a glorious new build project in the Thredling Hundred, mid Suffolk. Close to the village centre of Debenham, this outstanding and spacious home is surrounded by outbuildings, both old and new. A new two-storey car lodge offers accommodation on the first floor and sits beside an original 1914 barn, while the jewel in the crown is the converted tower mill which dates back to 1839. The two acre estate was purchased at auction, subject to planning, and provides far reaching views of the stunning Suffolk landscape, an area of Outstanding Natural Beauty and birthplace of John Constable.

“There is certainly a lot of history attached to this spot and I recall we were surprised and delighted that local planners allowed us to replace the existing cottage that was on this site,” says Joe Johnson. “The property was very run down and needed considerable work to make it habitable so for us it made total sense to knock it down and start again. In fact the whole site was in need of recovery, high roadside hedges completely obscured the buildings and the mill was so deeply covered in bramble that we couldn’t even see the brick building beneath.”

Joe and Sandra Johnson designed the house themselves together with architect Tim Linstead of Anglia Design LLP, Norwich. The property incorporates the very latest technology including air source heat pump, photovoltaic solar panels and a heat recovery ventilation system, which together has resulted in a highly sustainable building. The open plan kitchen and day room is reached via a generous utility room which is adjacent to the gym. The day lounge is flanked by a contemporary garden room, with natural solid timber features, and offers far reaching rural views across the moated garden. Bricks and beams reclaimed from the original cottage have been used to create a large and welcoming inglenook fireplace which houses a log burning stove in the day lounge.

In the spacious entrance hall, which serves two formal reception rooms, a regal two way oak staircase leads to a minstrels gallery and five double bedroom suites. A large floored-out area in the roof space above provides substantial and valuable storage and can be reached via its own door and staircase off the first floor landing.

“We started the build in autumn 2014 having meticulously planned the build schedule”, continues Joe, “and we moved into the house in November ’16. Work is still ongoing to the mill which is reported to have been one of the finest examples of a tower mill in the country.” The mill was originally five stories at a height of 57ft with four sails. It was tail-winded in July 1918 and suffered significant damage. The mill was repaired using the sails from Preston Mill, near Lavenham in Suffolk, with the help of a £100 Government grant. The mill was set to work again on 21 June 1921, working until 1935. It then stood derelict until December 1962 when it was literally pulled down to a two-storey stump. The truncated mill has been extended to the rear by the Johnson’s and will provide lovely accommodation for visitors to the region.

As a successful carpenter and builder Joe Johnson is familiar with the specification of many leading materials’ and systems and presented Sahtas UK with drawings early in 2015. “It has been a delight to work with Joe and Sandra on this very ambitious build and I know how much hard work and effort has gone into the last three years,” says Iain Webster, director of Sahtas UK Limited. Working with samples of the Brookhurst natural clay roof tiles, the couple chose the Wentworth tile for the main house and the rear extension to the mill. “In fact, this was the first project to specify the Wentworth when it was first launched so we are pleased and proud that it was chosen for such a special build,” comments Iain. “The Wentworth gives the feel of a weathered, reclaimed tile with its dark red base and heavy dark weathering that looks old and established from the very first day.”

Brookhurst tiles are made from the highest quality clay material using traditional hand moulding and coal firing techniques. Whilst these glorious traditions are maintained, Brookhurst tiles meet the highest technical standards and are fully compliant with BS EN 538 and 539 test standards for strength, durability and weather protection. The artisan skills of this production method has also founded a vast inventory of bespoke designs, intricate and unique shapes, and varied components with refined colour matches essential where extensive renovation is undertaken.
Externally, the original barn has been fully restored and the clay pantiles have been replaced with well-matched reclaimed tiles. “It was important to source a good match for the new build car lodge as the two barns sit side by side,” says Joe. “Here Sahtas helped us again and colour matched the tiles in Turkey and shipped samples back to the UK. We were delighted with these and most of our visitors can’t identify the old from the new.”

Sahtas traditional pantiles are manufactured to the same high standards as the rest of the collection and available in the same colourways as the Brookhurst tile range. “We will always help clients who have a very specific requirement, or regional bias, and if we have to make something bespoke we have the capacity to do so,” comments Iain. “We are passionate about producing premium handmade clay products which exceed the expectations of both the industry and our customers. This goal is achieved through stringent in-house quality control at all levels, as well as continuous external independent testing. Bespoke or not, all Sahtas products are backed by our 100% quality guarantee.”

Cembrit’s Brazilian scores on cricket ground

Two cricket teams in Nottingham now have a new home, thanks to Cembrit and its Alpina natural slates, as the aesthetically pleasing material has completed the look on a newly built cricket clubhouse.

Called the Field of Dreams, the new cricket clubhouse is based at the Meadows Recreation Ground in Nottingham’s Victoria Embankment. The project, which received a £150,000 Sport England grant, was the vision of the Trent Bridge Community Trust. With the original pavilion being old and dilapidated, the new clubhouse was built to provide four changing rooms, a kitchen, disability access, rooms for officials, and external viewing area.

Nottingham-based architect, Maber worked with construction giant, Willmott Dixon, while J Wright Roofing, was sub-contracted to provide an economical roofing system. Familiar with the benefits of Cembrit’s roofing products, J Wright Roofing specified and installed approximately 8,500 Alpina grey/green natural slates. Supplied quickly and efficiently via leading distributor of high-quality natural slates, East Midlands Roofing Supplies, the roof was installed within a month.

“This was an exciting project to be involved in, as it attracted the support of many local businesses and benefited from fundraising efforts” explains Jason Wright, Managing Director of J Wright Roofing Ltd. “The aim of the project was to ensure that cricket continues to be played at this site for the next 100 years. Thanks to the durable and high performance features of Cembrit Alpina slates, the roof will last the lifetime of the clubhouse.”

Alpina is a Brazilian natural slate, selected from the finest deposits and produced at some of the best facilities in Papagaios, Brazil. It is available in two colours, graphite and grey/green and in a variety of sizes. With its flat surface and pleasing shade variations, Alpina slate can be relied upon to create an attractive, high-performance roof.

Alpina slate is a tough natural material which has been tested to ensure it meets the current national standard, BS EN 12326-1:2004. Alpina slate has virtually no unstable minerals such as pyrites, graphite, carbon and un-oxidised irons and will withstand the most severe weather conditions: they are unaffected by sunlight, ultraviolet light and even acid rain. Laid correctly Alpina slate will last the lifetime of a building and are ideal for use on any type of project.

Impressive Center Parcs roof refurb completed with zero guest disruption

With capacity for almost 4000 guests and 96% occupancy, keeping the central area of Center Parcs Longleat Forest open was key to the refurbishment of its impressive Subtropical Swimming Paradise. A massive challenge for Delomac Roofing, the project to renew the roof with a Sika Sarnafil membrane was accomplished with two years of meticulous planning and 30 months of onsite construction.

Originally completed in 1994, the Subtropical Swimming Paradise roof and glazed rain-screen systems were in need of refurbishment. The new roof installation was planned in close discussion with the Sika Sarnafil and Delomac supply chain, developing the specification to address all the client’s strict performance, environmental and aesthetic requirements.

Chris Meadows, Technical Advisor, Sika Sarnafil explained: “The client needed a durable, long lasting roof system that would complement the woodland setting. This was complicated by differences between the swimming pool side and dry side, with restaurants and meeting rooms, of the building.

“We proposed two distinct solutions– a mechanically fastened system using Sarnafil S327-18EL for the dry side and an adhered system using Sarnafil G410-18EL for the more humid area. Both were specified in Patina Green to blend with the natural environment. Sarnafil membranes are cold applied and free from naked flames, the obvious choice for an open site.”

An innovative temporary terraced platform was designed and installed, suspended underneath the main structure by cables and lattice beam scaffold units. Work was carried out over 16 separate sections, like a wagon wheel – ensuring the structure was not compromised by uneven load distribution. This stepped, terraced temporary roof was then covered with plywood and completely weathered by Delomac with a Sarnafil membrane.

With the temporary roof in place, existing glazing and coverings could be safely removed, maintaining water-tightness with guests enjoying the facilities below. Scheduled over more than two years, this way of working resulted in a dry building envelope, despite some of the wettest weather on record.

Comprehensive vapour barrier measures were used on the pool side of the building to ensure the high humidity chlorinated environment was contained. Robust SFS sealant and Sarnafil metal-lined vapour barrier detailing at all Glulam beams and fascia interfaces ensured no risk of condensation.

Sarnafil membrane and accessories were used for all the coverings, and again overall specification development was tailored to suit the varying build-ups; new, overlay, bonded and mechanically fastened. An increased thickness membrane was manufactured in one single batch to ensure colour consistency. Sika added further value with an impressive 17 visits to the site by the Applications Team to advice and support.

Brendan McNulty, Delomac Roofing, described the challenges the team faced during the project: “Installation methods and curved roof areas required our operatives to work from harness and rope access. We developed an innovative material loading trolley with the builder to deliver materials to the work sections safely, without compromising finishes.

“Workmanship standards remained exceptionally high, despite the challenging logistics, and met the client requirement of consistent lap and detail arrangement. This was also helped by the quality of the Sarnafil membranes. The finished installation has transformed the internal and external appearance of the building. Rooflights and white soffit finished decking have provided a bright and airy environment, with the external green finish blending subtly with the landscape.

“Most importantly, safe, unlimited guest access to the pool, restaurants and meeting areas was maintained throughout the entire project; something we’re very proud of.”

Vertigo gives distinct aesthetic to London extension project

A roof extension project in London has used an innovative fibre cement slate, specifically designed for vertical application, to create a distinctive, contemporary dormer conversion, which had to meet stringent local planning requirements. The project is one of the first in the UK to use the new Vertigo slates, which were developed by roofing and facades manufacturer Marley Eternit.

The home owner specified the Vertigo fibre cement slates to create a clean cut, precisely engineered, slate panel aesthetic for his dormer loft conversion and roof extension, forming a contrast against the riven tiles used on the existing roof and differentiating it from other roof extensions in the area.

The first of its kind in the UK, Vertigo consists of small 600mm by 300mm slate like panels which can be quickly fixed onto battens, with the desired amount of insulation in between. The fibre cement slates perfectly adapt to the contours of the building, providing a second protective skin.

He explains: “There are hundreds of similar roof extensions in Chiswick, all determined by the same stringent local planning requirements. We appointed PRS Builders to carry out a flat roof dormer conversion for us but we wanted something different, we didn’t want a ‘me-too’ extension. The idea was to create as modern an aesthetic as possible, using an innovative material, not the same type of vertically hung tiles used on other conversions in the area, but still working within the planning constraints.

“We originally chose zinc but it proved to be too expensive and not eco-friendly enough. When we heard about Vertigo, we changed the specification as it offered the stand out aesthetic we were looking for but was a more cost effective and sustainable option.”

The Vertigo slate range is very easy to fix by any builder or roofing contractor and has three different installation methods to give more design flexibility and freedom. On this project, PRS Builders fitted the Vertigo fibre cement slates using a panel installation, so that the regular bond panels give geometric precision. However, it can also be fitted using a traditional method of installation, which gives a natural slate appearance with slate hooks or another option is broken bond, where panels are staggered to give a close boarded effect.

The homeowner adds: “We’re really pleased with the finished effect, the extension blends in with surrounding roofscapes but at the same time, the Vertigo finish offers something a little bit different – a distinctive, yet under-stated, aesthetic that sets ours apart from all of the other similar dormer conversions in the area.”

Charlotte Hughes, marketing product manager from Marley Eternit, comments: “As architects, specifiers and self builders look to create stand out residential designs in urban areas, fibre cement is becoming an increasingly popular material, not only for the roof but also for vertical slating. We developed Vertigo to give more flexibility to specifiers and designers who want to use fibre cement slates across the whole building envelope. This innovative method of vertical slating uses invisible fixings to provide clean lines and a modern aesthetic and is perfectly suited to new build or refurbishment work.”

Lightweight, weather and temperature resistant and available in eight different colours from blue/black to terracotta, Vertigo slates can be used to create beautiful, distinctive and elegant vertical cladding solutions for a full range of building types. Perfect continuity between the roof and facade can be achieved by using Vertigo in combination with Marley Eternit’s Birkdale or Rivendale fibre cement roof slates.

Vertigo also boasts superb sustainability credentials, helping to achieve environmental credits with a ‘very good’ BES 6001 Responsible Sourcing accreditation and its own Environmental Product Declaration (EPD). Fibre cement also offers sustainability benefits throughout its whole life cycle, as it can be fully recycled at the end of its use. Waste fibre cement can be ground down and used to replace limestone and shale in clinker production, the essential ingredients for Portland cement.

Cembrit BBA certified slates provide natural finish to new housing development

Jutland, smooth and Zeeland, textured BBA certified fibre cement slates from Cembrit, have demonstrated their versatility, design and performance features on a stylish, nature-inspired housing development in the seaside town of Weymouth.

Pemberly consists of 176 houses, townhouses, apartments and bungalows, varying from one bedroom to four bedrooms in size. While the development is centrally located and within walking distance to shops, schools, amenities, a community centre, library and local transport, it still offers a tranquil living space.

Poole-based building contractor, F.H.Cummings worked with roofing specialist, Weatherbury Roofing on this project. Having installed Cembrit slates in the past, the roofer specified Jutland and Zeeland fibre cement slates for the new build properties. Finding a roofing material that would blend in with the natural surroundings, accommodate the varying roof pitches and meet the high specification requirements was a challenge for the contractor.

“We have experience of working with a number of different roofing materials, and this allowed us to make an informed decision that fibre cement slates would be the best option for this project”comments Simon Coleman, Contracts Manager of Weatherbury Roofing. “Cembrit fibre cement slates are lightweight and pre-holed, two features that were beneficial to us. This, combined with the fact that these slates don’t require any grading or sorting, meant that we were able to speed up the installation process. The fact that Cembrit’s slates come in a variety of surface textures allows us to choose a slate for each design.”

Cembrit holds five BBA (British Board of Agrément) Certificates for its fibre cement slate range, ensuring that whichever system is chosen, roofers and architects can be confident in the specified product. To achieve this status, Cembrit fibre cement slates completed a comprehensive testing process and successfully met all the requirements set out by the BBA.

Jutland and Zeeland slates are manufactured to the highest European standards using Portland cement together with a formulation of superior blended synthetic and cellulose fibres. Cembrit fibre cement slates are finished with a high quality, semi-matt acrylic coloured coating to the face and edges and a tinted, high performance binder to the back face. The slates are manufactured in accordance with a quality assurance system to ISO 9001 and to the requirements of BS EN 492:2012 product specification for fibre cement slates and their fittings.

Cembrit A/A+- rated fibre cement slates can contribute to achieving an environmentally outstanding building. The five variations (Jutland, Zeeland, Westerland, Moorland and Diamond) allow designers to achieve the highest ratings for roof specifications and are currently the only fibre cement slate certificated.

Cembrit B5 upgrades Penlan holiday homes

Cembrit B5 corrugated sheets have been installed on eight Swiss-style lodges at a holiday village in Swansea. The refurbishment of the roofs has updated the building, and provided a finish that exudes that holiday retreat feel.

Located in the heart of the beautiful Teifi Valley, Penlan Holiday Village is a small family run holiday park that is set amongst beautiful woodland and parkland. The development includes two and three bedroom detached lodges, a heated open-air swimming pool, picnic area, playing field and parking. The holiday village attracts many visitors throughout the year, as it provides quick access to the beautiful Teifi Valley and the West Wales Coastline.

Graham and Alistair Greenshield, the owners of Penlan Holiday Village wanted to replace the thirty year old roofs, as they were looking tired, and not performing very well. Graham chose to take on the job himself, and after looking at the options, decided to purchase Cembrit B5 corrugated sheets. Approximately 150 black coated B5 corrugated sheets have been installed on five lodges also utilising close-fitting one piece Cranked Crown Ridge to fit perfectly into the roof pitches.

“The exceptional quality of Cembrit’s B5 corrugated sheet helped us to enhance the exterior design of the lodges,” comments Graham Greenshield, part-owner of Penlan Holiday Village. “Time has been of the essence, considering the size of the project, and the fact that we didn’t want to close the business for too long. Cembrit’s B5 corrugated sheets have saved us a great deal of time, as it is quick and easy to install. In addition, its cost-effectiveness and design features ticked all the right boxes for us. I am not only pleased with the end result, but I enjoyed installing the product.”

The rust and rot free B5 Corrugated Sheet is the perfect solution for someone looking to clad or repair single-story buildings such as stables and garages. B5 is available in fourteen different lengths ranging from 4′ to 10′ 6″ the sheets are approximately 40% wider than traditional 3″ profile which allows for much better coverage per sheet. They also offer superior water shedding capacity due to the profile of its corrugations.

B5 offers numerous advantages that are helpful for the installer. B5 sheets have a small overlap, and as sheets are approximately 40% wider than comparative products, so it offers a much better coverage per sheet. This has the advantage of decreasing the weight of the roof covering. There is less side lap and overhang, and increased maximum end lap. B5 can be laid to a 5° pitch for small roof areas if the end laps are extended to 300mm and are double sealed with mastic strips. A number of accessories come with the B5. A one-piece close fitting Cranked Crown ridge that can fit into roof pitches, two-piece lose fitting ridge which is adjustable to roof pitches and the Plain Wing Angle ridge that can create high level ventilation. Also there is the Cemsix Barge Board which is used to close verges at gable ends and the one-piece and two-piece Roll Top Finial which forms an integral part of closing a verge apex.

Stunning roof for London pub with new Sika Sarnafil self-adhered membrane

Specialist roofing contractor Hambro Roofing has recently completed works to a new JD Wetherspoon pub in London, known as ‘The Mossy Well’, which now boasts 500sq m of Sika Sarnafil Self Adhered membrane.

JD Wetherspoon has spent just over £3 million developing the outlet on Muswell Hill, which opened in October.

Extensive refurbishment and adaptations to the building needed to take place due to the existing roofs being in such a bad state. Essex-based Sika Sarnafil contractor, Hambro Roofing, was awarded the contract after proposing to use Sika Sarnafil single ply for the flat roof repairs.

The refurbishment comprised of complex work on the existing pitched roofs, lead flashings, guttering and renewal of the flat roof. A section of new barrel roof was also required in the centre of the building; comprising of flat, vertical and soffit detailing.

The client required the new roof area to look like a traditional zinc roof covering. Sika Sarnafil G410-15 FSA was specified for the job, with décor profiling to match the surrounding roofs. Ideal for the job, the system is lightweight, cost effective and offers a flawless finish.

Built on Hambro Roofing’s previous experience this was a highly successful project without any major setbacks and completed in the given timeframe.

The barrel roof was also fitted with SarnaTherm insulation over a SarnaVap vapour barrier. Sikalastic Liquid Applied Membrane was used on the detailing around the guttering to achieve a seamless waterproof finish.

Jon Hammersley, Hambro Roofing Director, explained “The works were incredibly challenging as there was a vast amount of awkward detailing including vertical fascia and soffit works. However, the new Self Adhered membrane allowed us to work fast and make the roof look fantastic. Sarnafil remains our preferred partner when it comes to single ply roofing because it is so reliable and gives the best results.”

“We had to work to a tight deadline in order to get the premises open on time which was achieved with our own in house labour force and great workmanship with the product,” he added.

Feedback was enormously positive on completion of the project. The client was particularly impressed by the effectiveness of the Self Adhered solution and the speed in which the project was completed, resulting in a stunning roof that fulfilled the architect’s vision.

Sika Liquid Plastics solution allows Asda store to remain open during roof refurb

A popular Scunthorpe supermarket has recently benefited from a complete roof refurbishment using a Sika Liquid Plastics Built-Up Roof waterproofing system. The Asda store had to remain open throughout the project, requiring expert planning by Northampton-based contractor Ice Roofing.

The building, originally constructed in 1976, was suffering from water ingress and the roof was in urgent need of repair. To ensure that the store could remain trading throughout the project, the client required a cold applied waterproofing option. Managed by Uplands Retail Ltd, the contract involved a tight timescale to refurbish several of the supermarket’s large roof areas, totalling 2000sq m.

Ice Roofing, a Sika Liquid Plastics Quality Assured contractor, already had a good reputation with Asda thanks to a number of previous jobs and were the obvious choice for the job.

Gareth Davies, Ice Roofing, explained: “We knew that our partnership with Sika Liquid Plastics would give us the advantage of additional expertise when specifying a product for the project.

“The team at Sika conducted a detailed survey, including thermal imaging using the latest technology, allowing us to see where the real problem patches where. This enabled us to reduce the area of roof we would have to completely strip back to the steel deck, which was really significant in keeping disruption to a minimum.”

A further challenge presented itself when asbestos was found in areas of the felt that needed to be stripped away. Ice Roofing brought in the experts to remove the existing substrate containing asbestos, while maintaining the integrity of the store’s waterproofing and complying with strict HSE standards.

Completed in just 10 weeks, two teams of three first increased the height of the roof by increasing the insulation thickness around various complex details. Sika Liquid Plastics’ Decothane Gamma 20 roof coating system in Slate Grey was then applied over the entire roof area. The cold applied, zero flame, zero heat Built-Up Roof system allowed the store to remain operational throughout the works; a key benefit for the local community.

A mineralised walkway was also installed to enable ease of access for future maintenance work.

Gareth added: “We worked fast and smart to deliver a seamless finish on the roof, with the liquid system offering ease of application around plant and penetrations. The superior 20-year guarantee, signed off by Sika Liquid Plastics when works were completed, sealed the deal for the client.”

Decothane is available in the UK from Sika Liquid Plastics. For further information visit http://gbr.liquidplastics.sika.com or call the inquiry line on 0800 112 3826.
