New student accommodation block gets top marks with Cembrit

Cembrit PB and Cempanel building boards have been chosen as part of the construction of the façade of a brand new student accommodation block at the De Montfort University in Leicester. The Abode development on Newarke Street consists of sixty one student flats, located a short walk away from Leicester city centre.

De Montfort University is a public research and teaching university and it required new student accommodation for its growing student numbers. The accommodation is comprised of 143 rooms and students can benefit from being in close proximity to the beautiful River Soar and Bede Park. The Abode development is the second phase of new student accommodation, following on from the successful construction of the first phase which completed in September 2013. The Abode development opens in July 2014.

Derbyshire-based DS Insulation was the cladding contractor on the project and specified Cembrit PB and Cempanel Boards. The building boards have been fitted on every level of the seven story block, creating an insulating render system. The Cempanel was used as an inner lining board with Cembrit PB installed as an outer layer render backer for the façade of the building. The building has an attractive finish of which combines smooth white walls and red brick.

“The Cembrit building boards were the perfect choice for this project” commented Barry Bradbury, Site Manger from J A BALL LTD who worked with DS Insulation. “I have never worked with Cembrit before but I was really impressed with the quality of the boards. We could have used plasterboard on the flats but Cempanel is a much stronger product. I would not hesitate in using Cembrit for future projects.”

Cement based Cembrit PB, has low water absorbency and is dimensionally stable. It will neither expand nor contract with heat and cold, nor will it swell and shrink due to changes in moisture, crucial characteristics inhibiting surface cracking in the render finish. Cembrit PB’s specially developed reinforced, chamfered edges mean the board can be fixed close to their edges. This maximizes stability at the butt joints, further reducing the risk of the render cracking along the joints, which can be a vulnerable area of the facade.

Cempanel (cement particle board) is superior to timber and plasterboard panel products when used as internal linings on rainscreen cladding projects (sheathing), general purpose external boarding, floors or studwork interior walls. Cempanel is both stronger and less absorbent than timber and plasterboard. The high cement and alkaline content also resists insect and fungal attack.

Kladfix supports student housing with its KX01 fittings

Kladfix, the rainscreen cladding support system specialist has supplied KX01 fittings for a new development on Sefton Street, Liverpool. The £15 million student accommodation consists of 135 new halls for the University of Liverpool and is situated in the heart of the city centre, overlooking the Queen’s Dock.

With over 54,000 pupils attending The University of Liverpool, there is a high demand for student accommodation, which is based in close proximity to everything that Liverpool has to offer. The new multi storey student block, which is due to be completed later in the year, will allow residents to have easy access to; cultural sights, nightlife and shopping centres. To provide a unique exterior, four different types of rainscreen cladding have been specified; Zinc, Terrecotta, engineered stone and granite. Indbuild, the industrial building company installed Kladfix’s KX01 cladding support system for this project.

“The Kladfix system is incredibly versatile” commented Dave Kirby, Managing Director of Indbuild Limited. “The design of the project required four different types of cladding to be used on the exterior of the student accommodation and the KX01 system worked extremely well with all the different types of cladding and was easily installed. This isn’t the first time that we have worked with Kladfix and we would not hesitate to work with them again in the future.”

Kladfix KX01 fittings are suitable for use as a back frame system and are the basis to all of Kladfix’s systems. KX01 fittings are also used for face and rivet fixing for fibre cement, high-pressure laminate, ACM and metal rainscreen cladding panels.

Kladfix holds extensive stock to ensure orders can always be met and where necessary, immediate delivery can be provided. All Kladfix cladding systems can be engineered to project specific requirements thanks to the expertise of its technical design support service. This provides architects and specifiers freedom with an almost infinite range of façade appearance and layout options.

Sika Sarnafil specified for Donyngs leisure centre, Redhill

A Sika Sarnafil waterproofing roofing system has proved to be the perfect fit for The Donyngs Leisure Centre, Redhill following a major £4.1 million upgrade and refurbishment. The re-roofing project was initially to be completed in two phases but the Reigate and Banstead Borough Council was able to draw on more funds allowing both phases to be rolled out as one.

The new roof, which entailed overlaying a Trocal installation from 30 years ago now includes 2,000sq m of Sika Sarnafil waterproofing system. Surrey-based specialist trade contractor, Vision Design Projects successfully tendered for this project, whose operational manager and site staff had previously been involved with the original contractor who installed the old roof.

The isolating layer used was Sika Sarnafil type “T” fleece x 300g / m2 with the waterproofing membrane layer being S327-18EL which was mechanically fixed with IF/IG-C 82x40mm membrane pressure plates and SFS BS Stainless Steel self-drilling fixings. All up stands / outer eaves were then covered with preformed Sarnametal closures.

During the installation of the project, there were no crash decks fitted, just a cover over the swimming pool which was closed for the duration of the activities in this particular area, ensuring safety was first priority.

There was a specific requirement that led to the specification of the Sika Sarnafil system: “I originally identified that the existing pool roof was initially installed using non stainless fittings and my concern was that the fixings may corrode too much making the roof attachment unsafe,” Vision Design Projects Mike White comments. “However, it was confirmed the attachment was safe and following pull out tests and post the inspection of opening up samples, it proved no corrosion took place within the roof space.”

As the existing roof area was to be retained, the choice of a mechanically fixed Sarnafil system proved to be the best fit; this was preferable over a liquid applied or a bonded system. This choice meant the customer had full assurance that the existing roof would be attached to the existing roof decking by a mechanically fixed Sarnafil system.

The project was successfully completed to the client’s satisfaction, on time and budget with the pool re-opening on the agreed date.

“In my opinion this is one of the best re-roofing projects we have undertaken,” adds Mike. “Having said that the perimeter closures are fully visible from the ground and these are now new, crisp and clean to the general public below which is very pleasing!”

Social housing opt for modern fascia materials but retain heritage character

Part of the Solihull Community Housing portfolio, The Hermitage comprises of 10 one and two bed apartments and a number of large communal spaces. A detached red-brick building, built in 1863 by the Rev Charles Evans, a headmaster of King Edward School, Birmingham, The Hermitage has been a place of many things, for many people.

Following damage caused by a fire in 1905, The Hermitage was restored in 1915 and used by the Red Cross as a relief hospital for the wounded during WW1. Acquired by the Local Authority in 1920, the building became a children’s home until the early 1970s, with one former resident commenting, “The Hermitage was a huge, rambling house, but I remember it being very happy…” Acquired by Solihull Community Housing (SCH), and council run for around 35 years, work began in October 2012 on a £200k project to refurbish the property both internally and externally.

“The Hermitage isn’t a listed building,” says SCH project manager, Brian King, “…but it is important that we retain its character.” Easier said than done when working within the limitations of a social housing budget, yet for The Hermitage to not only last another 150 years but for SCH to meet its objective of becoming long term maintenance free, changes needed to be made.

“A large percentage of the original exterior products are manufactured from timber, from the roofline to the windows. As a result of weathering and irregular maintenance, performance was suffering, with draughty windows and rotten fascia boards. We needed to decrease the long-term maintenance and repair costs of the building with materials that can stand up to our climate. Our budget is public-funded, and when you have that kind of responsibility you want to make sure that you make that money work hard for you.”

Retaining the property’s character was a key factor, especially for the residents. As amenity housing, The Hermitage provides unsupported housing for older people. “Keeping the residents happy has always been a crucial part of the success of this refurb,” continues Brian. “Working with our contractors Berben Installations, we have held regular meetings with the residents to keep them informed; this has been the key to gaining and maintaining their support and patience during the works.”

With sympathy and integrity high on the agenda for this renovation project, an eye for detail has been integral to its success. One example of this has been the replica roofline manufactured and created by fascia system specialist, Swish Building Products. Having tendered competitively for the supply of roofline and rainwater products, the Tamworth-based business also showed awareness and understanding of the building’s character in its response.

“The Hermitage has particularly ornate fascia boards,” said Brian. “We wanted to reproduce this, and emulate this feature but using maintenance-free materials. Swish Building Products is renowned for its expertise in low-maintenance products, and was able to come up with a solution that appeased any doubts or scepticism about using PVC-U on a historic building.”

“Many people simply rule out PVC building products from day one, without considering that PVC is probably the most appropriate use of materials for this application given the exposed and inaccessible location of the fascia system.’” says Greg Wilde, marketing manager at Swish Building Products, “And when you see what’s been done with the new fascias and bargeboards at the Hermitage it shows what can be achieved when a bit of imagination is used.

Wilde concludes: “The building envelope is a significant and on-going cost, added to which is the repeat cost of labour, scaffolding, and site management, all costs that can be avoided by specifying appropriate materials.”

Following the original designs supplied by Solihull Community Housing, Swish Building Products created a prototype of the Gothic inspired bargeboards using a mixture of existing profiles, which dominates the vast gable ends of the building. Taking around six weeks to finalise, the prototype allowed the team to progress through the installation, once onsite, efficiently.

The fascias have been created using a standard product; “…but it is the innovative way in which we have built up these standard profiles that has allowed us to meet the brief both objectively and practically,” said Dave Osborne, technical manager for Swish Building Products. “A standard-sized fascia barge board profile is a maximum of 405mm deep, For the Hermitage we had to create an overall depth of 650mm. Using two colours, black and white, we combined up to 10 boards to create one section of gable end; including Scotia Moulding, Gee Pee half width, Gee Pee flat board, foiled Dee Mould and Square Fascia.

Aerial photography of the site also revealed ‘hidden’ roofs that the team didn’t know existed! For these and the other non-gable fascia, Swish Building Products supplied a 425mm profile.

Manufactured from 84% recycled material, and saving 70% of the CO2 that would be generated using 100% virgin material, rainwater products from the building product specialist were also specified. The additional roof spaces had to be taken into consideration when calculating the potential quantity of rainwater run-off – helping to determine the specification of guttering with a sufficient flow capacity and the system layout, including the number and position of outlets.

Swish Approved Commercial Contractor, and Birmingham-based renovation specialist, Berben Installations, was responsible for installing the roofline and rainwater products. Paul Tunley, managing director of Berben Installations commented: “Using Swish Building Products gave us flexibility. As we had the whole range at our disposal, as well as their expertise, we were able to complete the roofline without having to mix and match with competitor products or ranges. The team found the products very easy to work with and the design, created by Swish Building Products, Brian King and myself, easy to follow. I think everyone involved in the project is pleased with the way the roofline has turned out.”

Brian concluded: “We are incredibly fortunate to have a company such as Swish on our doorstep. To receive this type of dedication from a national business is second to none, but to be able to ‘tick’ our local supplier box is a big plus! As the project draws to a close we are on schedule and on target to meet our objectives. By using modern methods on a historic Solihull building we have been able to combine old and new seamlessly to provide a wonderful sheltered housing location that anyone would be delighted to call their home.”

SterlingOSB – perfect for refurbishment projects

Sterling OSB (oriented strand board) is ideal for all sorts of roofing, flooring and general building projects. And now builders are substituting plywood for Sterling OSB; it’s more cost-effective, environmentally-efficient, easy to use, and highly versatile.

Roofing and flooring (pictured) for outbuildings is a typical application be it a refurbishment or new build project.

SterlingOSB (Oriented Strand Board) is a multi-layered timber product which is very different from plywood. Instead of being made from alternate sheets of veneer placed at 90 degrees to each other, SterlingOSB is made from layering strands of wood in specific orientations and then bonding the layers with a resin.

Norbord, one of the world’s leading manufacturers of engineered wood-based panels, now produces eight types of Sterling OSB – SterlingOSB2, Sterling OSB3, SterlingOSB T&G, SterlingOSB – Conti, SterlingOSB Roofcoat, SterlingOSB Sitecoat and a range of three new SterlingOSB fire solutions. Each has been developed for specific applications.

Each panel is made from forest thinnings that are the by-product when small diameter timber is felled; this give better quality trees space to reach maturity. Being produced in the UK from local, sustainable, FSC-accredited timber and produced to the criteria of the environmental standard ISO 14401, SterlingOSB can be employed with confidence when environmental credentials are demanded.
