Cembrit is delighted that its Moorland fibre cement slates have been specified and installed at the new campus development at the University of Northampton. Situated on the River Nene the new Waterside Campus features a mixture of academic buildings and student accommodation. Specified by Stride Treglown and installed by Russell Roofing, the Moorland slates dressed edge provides an aesthetically pleasing natural looking roof covering, for the new prestigious student accommodation blocks at the university, at a lower installed cost than natural slate.

Located on a former brownfield site, the development responds to the industrial heritage of the site in a contemporary way. The student residences are located immediately adjacent to the new academic accommodation and incorporate a variety of additional facilities including a health centre, multi-faith chaplaincy, convenience store, bank, hotel school and launderette. The additional facilities within the development take a holistic approach to urban regeneration as well as giving the university an opportunity to consolidate its campus estate into one location. The new student residences, which are being developed in two phases, consist of a mixture of shared townhouse and cluster flat accommodation with the Moorland slates being installed on pitched roof areas including the main roof and mansard sections.

Keystone Roofing have supplied Russell Roofing with over 47,000m² Moorland slates so far and Frazer Simpson, Director of Russell Roofing is delighted with how the project is taking shape: “The development is a great looking project and looks particularly impressive with its waterfront location. The Moorland slates fit in perfectly with the surrounding and with their dressed edge and lightweight construction add a classy, but easy to install quality to the project. We’ve used them before and definitely will do again.”

Cembrit Moorland slates are designed with a dressed edge and smooth surface, they are light weight, pre holed and easy to cut with hand tools making them a cost effective product an added benefit for the University of Northampton. Moorland slates random, dressed edge creates a roof slope with a natural appearance, they are fully coated with a high quality, semi-matt acrylic pigmented finish which ensures the natural appearance is visible from street level.

Cembrit Glendyne natural slates have been specified and installed on a unique renovation project for the Historic Hampshire landmark, Netley Chapel, which saw the local community contributing financially to the restoration project. Before slating began, the public were invited to site to mark the occasion and “sponsor a slate”. For a small donation, visitors wrote a message and signed the reverse of a roof slate. More than 900 Glendyne slates were decorated, raising £6,600 for the friends of the Royal Victoria Country Park. These slates were then installed on the roof of the chapel by Elliotts Premier Roofing of Southampton.

Royal Victoria Country Park was once the site of the world’s largest military hospital, the Royal Victoria Hospital (or Netley Hospital). Now, all that remains of the original hospital structure, which fell into decline after being severely damaged by fire in 1963, is Netley Chapel. Thanks to a multi-million pound grant from Hampshire County Council and the Heritage Lottery Fund, the Victorian-era building has recently undergone extensive renovation, and now marks the beginning of a new chapter for the chapel.

Hampshire-based construction company, Brymor Construction was appointed as the main contractor for the project alongside roofing subcontractor, Elliotts Premier Roofing. Having worked with Cembrit many times in the past, Elliotts Premier Roofing selected 610mm x 305mm blue-grey Cembrit Glendyne natural slates for the refurbishment of the roof covering: “As one of the oldest companies in Southampton, it’s been a privilege for us to have played such a pivotal role in this project and work with other local organisations to restore this iconic chapel,” says David Stubbington of Elliotts Premier Roofing. “We chose Cembrit Glendyne slates for the project due to its flexibility to accommodate the roof design of the prestigious building. The end result is impressive and Glendyne really accentuates the character of the chapel.”

The chapel re-opened to the public in summer 2018. An exhibition in the main body of the chapel tells the story of the former hospital, from its beginnings in the 1850s, through the Boer War, and both World Wars up to the present day.

The project was completed in a timely fashion, and is one of the first to utilise the new large 24″ x 12″ (imperial) format. Netley Chapel was finished to an extremely high standard. Cembrit was on hand to offer support and advice for this landmark renovation project. “I assisted Hampshire Council with writing the roofing specification for this project,” commented Phil Wilden, Technical Manager Pitched & Small Element Roofing Products at Cembrit. “Throughout the roof construction phase, our Regional Sales Manager and I made routine visits to the site to ensure the product was being installed to the requirements of the specification and that of British Standard BS5534. This highlights the level of technical support that we offer our customers.”

Glendyne is a high quality slate that combines first-class performance with all the inherent beauty of natural slate, making it the ideal ‘natural’ choice for specifiers and roofers. Available exclusively from Cembrit in the UK, Glendyne is a distinctive blue-grey colour. The Glendyne quarry is one of the most modern slate quarries in the world. The quarry operates a quality management system based on EN ISO 9001 which is externally audited. This standard is adhered to rigidly, as are all quality standard procedures required by each regional market the quarry supplies.

Glendyne is tested to BS EN European standard, BS EN 12326-1:2014 which requires many of the laboratory tests (‘type testing’) to be performed at least annually and the factory production control (FPC) performed and recorded as a matter of routine by the producer.

The Triangle, Cambridge Assessment’s new international headquarters, brings together all the company’s Cambridge-based staff under one Alumasc-protected roof.

Designed by HLM/Sidell Gibson Architects, all flat roof areas utilise Alumasc Roofing Systems’ Hydrotech Hot Melt and Alumasc XPS insulation, offering a total system solution. All upper main roof areas drain onto 3 x single storey podiums that have the patented, single source Alumasc BluRoof Drainage System, along with Blackdown Green Roof to provide a habitable space for people to enjoy.

Alumasc’s BluRoof system reduces and controls the peak rate of storm water discharge from roof areas. Detention of storm water up to a prescribed maximum hydraulic head occurs, with subsequent discharge controlled over an elongated time period.

The BluRoof drainage strategies were introduced at design stage to help meet SuDS (Sustainable Drainage Systems) requirements, and Alumasc worked extensively with Capita to achieve the required reduction in rainwater run-off.

Wayne Farrington from Cambridge Flat Roofing, the Alumasc-registered approved contractor which carried out the installation, acting as sub-contractor to Bouygues UK, said “This has been an excellent contract to be involved in, one of our first major BluRoof projects. The level of service and input from Alumasc’s Technical department, both internally and on-site, along with Alumasc’s Customer Services team, have been outstanding.

“Combined with the Hydrotech BluRoof Structural Waterproofing system, a system we have significant trust and experience in installing, we feel we’ve delivered a project we can be proud of. The feedback we’ve received from our client has been extremely positive and we look forward to our next Alumasc BluRoof.”

Easy to install Cembrit Moorland Blue/Black slates have been used on phase two of St Modwen’s new build housing development in Dursley, Gloucestershire. Chosen for their attractive appearance, and following a successful phase one, the Moorlands were once again supplied by Willis Westcott and installed by Mcdonnell-Price, a local roofing contractor.

The properties at Littlecombe have been built using a blend of modern and traditional materials which gives the development a timeless appeal. The Moorland Blue/Black slates provide a contrast with the light coloured fascia materials and surrounding greenery. This clean appearance is enhanced by the first class installation work carried out by McDonnell-Price across the development, which features roofs with Velux windows and many vents and valleys, alongside several pitch variants of between 30 and 45 degrees. Brandon McDonnell, of McDonnell-Price is very satisfied with the end result:

“I’m pleased with the way the project came together – everything just seemed to click into place. We like Cembrit’s Moorland slates and with a project like this, one that involves a lot of detail, it was good to have a slate that is lightweight, as well as easy to cut and fix. I also like the way dark Blue/Black colour stands out and nicely defines the roof lines against the surroundings.”

Moorland 600×300 slates were supplied by Willis Westcott, a large roofing supplies merchant in the region, as well as ‘doubles’ for the verges. The slates are fixed with two copper nails at the top of each slate with a copper rivet supporting the bottom of each slate. Moorland slates have an appearance close to that of natural slate. Their smooth surface and authentic dressed edges lend themselves to all manner of prestigious applications. They are manufactured to the highest European standards and are lightweight, pre-holed, suitable for all types of projects, easy to handle and install, durable and an economic alternative to natural roofing materials.

Moorland slates are manufactured using Portland cement together with a non-asbestos formulation of superior blended synthetic and cellulose fibres. Moorland slates are pigmented during production and are fully compressed. They are finished with a high quality, semi-matt acrylic coloured coating to the top face and edges and a tinted, high performance binder to the back face.

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.

Cembrit, the leading roofing and cladding specialist is proud to announce the addition of two new sizes to its Glendyne range of natural slates, 60×30 and 50×30, offering roofers larger slates and more versatility when working on lower pitched roofs.

On a roof with a lower pitch, the large size of the slates will not let water sit between the slates and prevents the water from getting through. Larger slates work well on low pitched roofs and are best suited for use in coastal areas where the environment has a greater degree of moisture content.

The larger sized Glendyne natural slates, 60×30 and 50×30, can be pitched at a minimum of 25° and 20° in moderate exposure zones and 30° and 22.5° in sever exposure zones respectively. The slates exceed the common 2:1 length width ratio, allowing for specification on greater range of roof pitches. The range offers a quality alternative to Welsh Slate and is readily available. Cembrit also has the facility to examine individual cases and offer specific advice on minimum pitch per project outside the parameters of BS 5534.

Glendyne is a high quality slate that combines first-class performance with all the inherent beauty of natural slate, making it the ideal ‘natural’ choice for specifiers and roofers. Available exclusively from Cembrit in the UK, Glendyne is a distinctive blue-grey colour. The Glendyne quarry is one of the most modern slate quarries in the world. The quarry operates a quality management system based on EN ISO 9001 which is externally audited. This standard is adhered to rigidly, as are all quality standard procedures required by each regional market the quarry supplies. Glendyne, like all natural slate from Cembrit, is tested to BS EN European standard, BS EN 12326-1:2014 which requires many of the laboratory tests (‘type testing’) to be performed at least annually and the factory production control (FPC) performed and recorded as a matter of routine by the producer.

Alumasc Roofing Systems’ Monoscreed is a fast-curing, solvent and isocyanate-free PMMA-based compound screed that can be cold applied to concrete decks (3mm – 50mm) to reduce deck deflection/back-falls and bring deck levels back to tolerance – i.e. zero falls.

Fast cure time

Unaffected by ambient temperatures, the system is rainproof within 15 minutes of being applied and will fully cure in circa 45 minutes, thus offering significant programme benefits when compared with more traditional screeds.

Application to substrate

Comprising resin, filler and aggregate mix, Monoscreed can be mixed at roof level and applied directly to suitably prepared – free from dust, dampness, laitance, grease, oil and other contamination, and if necessary primed with Alumasc Bitumen Primer – cementitious concrete.

The system comes in pre-measured packs of components palletised to ensure easy transportation to roof level and accuracy of the compound mix.

Overlaying

Monoscreed is also suitable to be installed over Hydrotech 6125, Derbigum bituminous membranes and Caltech QC cold-applied liquid where necessary.

High quality fibre cement slates from Cembrit have complemented the quality new build homes that David Wilson Homes has developed in South Wales. Providing a sleek and stylish finish, the dressed edge Moorland slates have made light work of a complex roofing project.

St Canna’s Green is a newly built David Wilson Homes development comprising 40 three, four and five bedroom properties. Located in the village of Llangan in South Wales, the homes have been carefully crafted to meet the needs to today’s lifestyles, delivering stylish, spacious, light and airy spaces that perfectly match modern lifestyle and aspirations. Multiple properties within the development feature complex roofing designs, with different roof pitches ranging from 35° to 45°, rafter pitches, dormer and rooflight windows requiring a roof covering that could accommodate these details.

Bridgend-based roofing company, Rooftop Tiling Ltd was appointed as the main contractor for this project. Having referred to the project requirements, the contractor recognised that the requirement for a roofing material that could be easily cut and installed on multi pitched roof designs. Whilst looking natural from the ground, Rooftop Tiling Ltd specified Cembrit Moorland dressed edge slates and sourced these products in 600mm x 300mm blue/black from its local builder’s merchant, Robert Price Ltd.

“David Wilson Homes is known to deliver high quality new builds which are aesthetically pleasing,” says Nick Pritchard, Commercial Manager at Rooftop Tiling Ltd. “We wanted to ensure we deliver this finish to the St Canna’s Green project by installing a visually attractive slate that could also handle the complex roof design. We are pleased with the end result. The slates complement the design of the individual properties, and the development as a whole”

Moorland fibre cement slates are manufactured using Portland cement together with a non-asbestos formulation of blended synthetic and cellulose fibres. Each slate is pigmented during production and fully compressed. The edges are dressed and then the slates are finished with a high quality, semi-matt acrylic coloured coating to the top face and edges, and a clear binder to the back face.

Cembrit Moorland Slates are manufactured in accordance to BS EN ISO 9001: 2000 and BS EN 492: 2004 product specification for fibre cement slates and their fittings.

Palmerston School, based in Liverpool, provides education to 11-19 year olds with profound learning difficulties. Palmerston identified a need for a new school building as staff and pupils were hampered by the lack of outdoor space and modern learning facilities. The former Aigburth High secondary school site was selected on which to construct its new £7m facility.

The new T-shaped single storey building includes a sports and dining hall plus a new hydrotherapy and splash pool together with sensory learning spaces. There is also a five-a-side football pitch and four-lane grass running track around the pitch perimeter. The project started in April 2016 and is due for completion summer 2017 when pupils will move from the existing location in Woolton to Minehead Road in the Aigburth area of Liverpool.

Early Stages

Originally planned as a timber frame construction, the main contractor asked voestalpine Metsec plc to review the school design and see whether a load bearing steel frame solution (SFS) could be offered. Taking a consultative approach, Metsec was able to advise the main contractors on the layout, and worked in conjunction with installers, local company Mark One.

As the first tier 2 designer and manufacturer certified to BIM Level 2 for Design and Construction in the UK by the BSI, Metsec used its BIM capabilities within the design stages to provide detailed plans and costings. Metsec was required on-site from the start of the project, completing the steel framing in the summer of 2016.

Designing the SFS solution for Palmerston School using Revit, Metsec attended regular main contractor team meetings with the BIM model, allowing any issues to be resolved in advance of the build. By using BIM, the project benefitted from a reduced timing programme and no waste, both providing subsequent cost savings.

Design Requirements

The blueprint of the school building presented several structural challenges, but were all incorporated into the BIM model from Metsec, including the design aspects of the roof. Studs within the joisted roof were extended out to overhang the external walls in order to create the overhang desired. Another roofing design requirement within the structure was a duo pitched roof. To enable the sloping element, Metsec used longer stud sections of a high gauge to accommodate the longer spans required and the larger load placed on the studs.

The school has invested in a substantial server room, in order to house the complex technologies being implemented into the school, which required a large number of ducts. This needed a substantial amount of openings within the wall which Metsec incorporated into the specification.

Partnership

Metsec’s engagement in the project from the early stages meant it could provide bespoke, flexible solutions integral to enabling the complex design aspects desired by the client.
Steve Williams, director at Mark One, said: “Working alongside the manufacturer from the early stages of the project meant that we could work in conjunction with Metsec in designing and delivering the additional design requirements, and it was a smooth running project all round.

Ryan Simmonds, sales director of framing at Metsec, said “Palmerston School was an interesting project from a design perspective and, in using BIM, all parties benefited from a central model that could be amended and revised throughout the early stages to produce an accurate plan during the delivery stages.”
