Bells Sports Centre, Perth

Celebrating its 50th anniversary in 2019, the iconic Bell’s Sports Centre in Perth, needed a new roof to protect the building. With the previous roof membrane nearing 30 years old the centre needed a long-term and robust roofing solution. The product of choice was the mechanically fixed Sarnafil S327-15 EL Light Grey as it is more than able to cope with all the extremes of the Scottish weather and has been certified by the BBA to last in excess of 40 years. The durability of the single ply material ensured a long-lasting solution for the project.

Center Parcs, Longleat

With capacity for almost 4,000 guests and 96 percent occupancy, Longleat Center Parcs had to make sure there was absolutely no disruption for its guests during the refurbishment of its Subtropical Swimming Paradise. Two distinct solutions were proposed – 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.

Costco in Farnborough

The new Costco warehouse in Farnborough is just one of 45 being built across the country by the leading wholesale giant as part of its UK expansion plans. A Sika Sarnafil waterproofing system has proved to be the perfect fit for the new 12,000sq m Costco warehouse. The size of the project and the quick installation time required resulted in the specification of the Sika Sarnafil S327-18EL membrane in Light Grey. Ideal for the job, the system is formulated for direct exposure to weather and is produced with integral polyester scrim reinforcement for high strength.

Ewart Grove, London

In a complex new build roofing project that was deemed almost impossible, Contour Roofing stepped up to the challenge with a Sika Sarnafil membrane. With truly stunning results, the project impressed the judges of the prestigious NFRC UK Roofing Awards, winning the Single Ply category. In partnership with Sika Sarnafil, Contour quickly presented a new bespoke specification; an adhered system using Sarnafil G410-15ELF Lead Grey with a polyester fleece backing as the main roof sheet for a flawless result and Sarnafil G410-15EL Lead Grey for all the detail work flashings.

Fitzwilliam College, Cambridge

Sika's full suit of products helped with waterproofing the scalloped roof at the campus. A combination of Sike Sarnafils waterproof Single Ply membrane, as a flexible and robust membrane, and Sikalastic- 621, as a highly-durable elastic liquid polyurethane system, was used. As well as the roof refurbishment, concrete repairs were also carried out with the use of Sika MonoTop-615 and Sikagard - 550. For the steel reinforcement Sika FerroGard-903 was also used. The refurbishment of the buliding was a great project for Sika to work on as it had solutions for each aspect of the project.

Joseph Black Building

The Joseph Black Building, found in the King’s Buildings Campus at the University of Edinburgh, houses the School of Chemistry and is one of the oldest buildings on the campus. But its existing copper roof covering had come to the end of its natural life. Sika Sarnafil’s flagship Sarnafil Plus refurbishment offer was the perfect solution for this project. Sika Sarnafil Membrane S327-15EL in Patina Green was chosen to replace the old roof covering, as the local authority planning department advised that this product was an acceptable replacement for the original copper roofs on the listed building.

Lakenheath Community Primary School

After worrying roof leaks and subsequent damage were discovered at Lakenheath Community Primary School in Suffolk, an urgent refurbishment of some areas of the roof was required to keep the school open and in a good state of repair. Concertus chose the Sarnafil Plus refurbishment team for the project, as they could provide support every step of the way, making sure the refurbishment ran smoothly. From initial surveys and bespoke specification, to finding the right contractor for the job and supporting them on-site, the Sarnafil Plus package offered a complete solution for a fast, hassle free refurbishment.

Leeds Arena

The new Leeds Arena was a £60m project by Leeds Council to create a striking new stadium, which has been crowned with a 7,500sq m Sika Sarnafil single ply roofing system, installed by experienced contractor Lakesmere. The fact that Sika Sarnafil was the first roofing manufacturer to be BIM ready played a huge part in the specification, and in turn improved the ability to review designs and rationalise ideas, whilst cost saving using BIM was highlighted through material specifications and design coordination.

Manchester Arena

Manchester Arena, managed and operated by SMG Europe, is one of the busiest venues in the world, and the largest indoor arena in Europe. A leaky roof, specifically in the area where the existing roof of the arena joined the railway station, was causing real concern and disruption. Following the roof survey, the Technical Team created a bespoke specification, including project specific detail drawings, tapered insulation plans and roof layouts, U-Value Calculations, Wind Uplift Calculations and Condensation Risk Analysis.

National Gallery and Science Museum, London

The National Gallery and the Science Museum - two of London’s major and iconic visitor attractions built more than 150 years ago – required an extensive programme of roof upgrades and maintenance. Working with the National Gallery since 1995, the roof replacement and thermal upgrading project has seen in excess of 12,000sq m of Sika Sarnafil membranes installed, together with insulation, roof lights and walkways in a series of over 30 completed projects – including the complete Sainsbury Wing in 2008.

New Elgin Primary School, Elgin

With previous roof re-coverings proving problematic, two key requirements were highlighted, building the thermal performance to help save energy, and improving robustness, to mitigate damage caused by vandalism. The architect worked closely with Sarnafil to ensure the chosen roofing products provided the required detail, specification and performance. A Sarnafil HD bonded system was specified guaranteeing a high quality and durable roof. By combining the thickest single ply membrane available – 2mm – and the robust insulation board – SarnaTherm HD – the Sarnafil HD system offered a long-term, resilient and well-insulated roofing system with very low thermal conductivity.

Northamptonshire Schools

Financed by county council capital funds, Northamptonshire County Council undertook a multi-million pound remedial works programme on a number of schools originally built in the 1960’s and 1970’s. All of the buildings were suffering from some degree of water ingress, and the roofs needed to be brought in line with current building regulations for improved thermal performance. Sika Sarnafil’s specialist roofing contractors installed over 50,000m2 in light and lead grey of G410-18EL single ply membrane to the school roofs.

Norwich Castle

Overcoming the challenges facing the Council was key to the success of the project. These were health and safety, time, cost, and aesthetics. A cold applied system was used to secure the membrane, eliminating the need for naked flames on the roof. Norwich City Council commented, “The Castle Museum houses collections of national importance, not only did we have to consider the safety of staff and the public, but also the historic collections whose home is beneath the rotunda roof. The need to elimate hot works on this project was a huge issue in specifiying the products to be used.”

Princesshay Shopping Centre, Exeter

The £230m Princesshay Shopping Centre, in Exeter, officially opened to the public in September 2007, as part of the city’s biggest ever regeneration project, with over 70 shops, cafés and restaurants. The roof of the centre, installed when the building was constructed, had caused various problems throughout its life. A Sarnabar system in Lead Grey was chosen, with a T fleece between the composite deck and the mechanically fastened Sarnafil S327-18EL membrane. On a smaller roof with a plywood deck, Sarnafil G410-ELF, an adhered system with a fleece backing, was specified.

The Dunes, Perranporth

Situated just 10 short metres from the beach at Perranporth in Cornwall, The Dunes was a 14-month project challenged with unforgiving coastal weather and high expectations in terms of quality workmanship. Comprising 36 contemporary beachfront properties, the luxury development, completed features unobstructed views of the Atlantic. To withstand the South coast’s often extreme wind and rain, while matching the luxury aesthetic of the build a robust but aesthic solution was needed. Sika Sarnafil’s single ply membrane was specified as the solution and to also ensure a high-quality and cost-effective finish was provided.

The Serpentine Building

The £11.6 million regeneration scheme in Aylesbury saw a former MoD site managed by the Homes and Communities Agency (HCA) transformed into an affordable and sustainable housing development, comprising 94 terraced houses and apartment blocks forming a continuous curved building. Named ‘The Serpentine’, this snaking housing project called for a flexible roofing solution! Sika Sarnafil single ply was specified for its flexibility and suitability to tricky detailing but the shape posed a number of technical challenges.

V&A Museum, Dundee

Spanning an impressive 8,500m2, the three-storey building makes a striking centrepiece on the water’s edge. With its BREEAM requirements, waterfront position, and proximity to the coast, it was essential that the building’s roof be designed and installed to meet sustainability criteria, whilst being watertight and robust to withstand the elements. As the system needed to exceed a lifespan of 20 years in a coastal region, Sarnafil specified its thickest membrane with a 25-year guarantee – a 2mm membrane, Sarnafil HD, to withstand the elements on the main field area which it currently is doing extremely well.

Walkie Talkie Building

At a dizzying 160m (525ft) tall, London’s distinctive Walkie Talkie building required an exceptional roofing solution. Designed by architect Rafael Viñoly and costing over £200 million, 20 Fenchurch Street is a 34-storey commercial skyscraper in London, known as the ‘Walkie Talkie’ building due to its top-heavy form. It is designed to have a BREEAM excellence rating. Sarnafil G410-12EL single ply provided the perfect solution to this design criteria, thanks to its excellent flexibility and weldabilty, while offering outstanding resistance to weathering, including permanent UV irradiation.
