Main Roofing Systems:

Adhered Roofs:

An adhered system will typically consist of a structural deck, adhered vapour control layer, adhered or mechanically fastened thermal insulation and adhered Sarnafil membrane.

Mechanically Fastened:

Mechanically fastened systems are suitable for both new and refurbishment projects of any size, providing cost efficient roofing systems for exposed applications.

Green Roofs:

Green roof systems are specified for a variety of reasons, principally to manage incident rainfall or to replace the biodiverse footprint that construction destroys; creating habitat for flora and fauna. But green roofs provide a wide variety of additional benefits including amenity, thermal mass, pollution reduction, natural cooling and aesthetics.

Ballasted Roofs:

A ballasted roof is one where the roofing membrane is restrained by means of either gravel or paving slabs. Green roofs are also classed as ballasted roofs but are covered in a specific section within this site.

Sika SolaRoof Is a 20 year guaranteed Solar Roof System based on an engineered non penetrative and lightweight mounting system the Sika SolarMount-1. Sika SolarMount-1 is an aerodynamic, lightweight mounting system for the installation of rigid Photovoltaic (PV) panels to flat roofs.

SIKA AND PARTNERS CELEBRATE WINNING PROJECT IN FIRST-EVER AJ SPECIFICATION AWARDS

March 2019

SIKA AND PARTNERS CELEBRATE WINNING PROJECT IN FIRST-EVER AJ SPECIFICATION AWARDS

Market-leading single ply roofing manufacturer Sika Sarnafil, architects Cullinan Studio and Roofing Contractors Cambridge (RCC) are celebrating following a win at the first-ever AJ Specification Awards.

The roof refurbishment of the Central Building at Cambridge University’s Fitzwilliam College – one of the first major projects to use a pioneering, new approach to Sika Sarnafil’s products – came out on top in the Roofing and Drainage category.

Announced at a ceremony held at The Principal Hotel in Manchester on Friday 15 February, prizes were taken home across a total of 12 categories for projects demonstrating outstanding working relationships between architects, manufacturers and suppliers.

In what was a skilful collaboration between Sarnafil, Cullinan and RCC, the judges agreed there was something special about the way this unique brutalist building had been beautifully protected.

Comprising protruding ‘scalloped’ detailing, an innovative waterproofing solution was created to refurbish the highly complex roof, all without visually altering the original 1960s Denys Lasdun design.

Sika Sarnafil’s single ply membrane and Sikalastic 621 – a liquid-applied product typically used for areas with complex detailing – were used across large areas. This pairing of systems was further enhanced by Sika Refurbishment’s SikaFloor 420.

Sika Limited’s concrete products were also specified for the build by concrete repair contractors Gunite Eastern. Sika’s innovative concrete repair system included a steel corrosion inhibitor. Sika® FerroGard®-903+, which penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel, was used alongside Sika MonoTop® repair mortars. The concrete was finished with Sikagard®-550W, a high-performance anti-carbonation coating, with crack-bridging capabilities, that protects the concrete, while meeting the aesthetic requirements of the structure.

Sika has a wide range of products available for most applications within the construction industry, which can range from waterproofing, flooring, concrete, sealing and bonding, facade, roofing and refurbishment applications, as well as teams of specialists available to advise on specific projects. Using a combination of systems, while working internally within the company, Sika was able to advise on the most suitable materials for different aspects of the project and ultimately provided a complete building envelope solution, with the client benefitting from having only one supplier to deal with.

Neil Smith, Technical Advisor at Sika Sarnafil, said: “We’re exceptionally proud that the teams across Cullianan Studio, RCC and Sika Sarnafil have been commended by the AJ Specification Awards. The winning project posed a huge design challenge, which was met with a unique approach and use of materials. Completed early and on budget, while the college remained operational throughout, the success of this project is testament to the close working relationships we foster with our highly skilled architects, contractors and clients, while also providing the best quality products.”

Dave Stewart at RCC said he was thrilled to see a project his team had worked on recognised in such prestigious awards: “The central Building Lantern roof was very unusual, presenting numerous detailing challenges that we welcomed. We worked closely with Sika Sarnafil and carried out multiple site tests to ensure the junction between the Sikalastic 621 and single ply membrane was formed using the most effective methods. The use of Sarnametal created a strong bond between the two products, enabling them to be successfully sealed together. This was a challenging and enjoyable project that demonstrates how well these products can work together for roofs with incredibly complex detailing.”

Alex Abbey from Cullinan Studio added: ''We are thrilled that, together as a team, we have won this award. This iconic, brutalist gem of a building is now renewed and preserved for many years to come due to an innovative shell, fascia and roof waterproofing solution, achieved through collaboration. The pioneering approach developed on this project can now be applied to protect other buildings, opening up new possibilities for roof design in the future.''

DURABLE SIKA PRODUCTS MAKE STUNNING BEACH DEVELOPMENT FIT TO FIGHT THE ELEMENTS

January 2019

DURABLE SIKA PRODUCTS MAKE STUNNING BEACH DEVELOPMENT FIT TO FIGHT THE ELEMENTS

The Dunes, a stunning new beachfront development in Perranporth, Cornwall, has seen a combination of Sika products used in order to create a durable solution for the roof and balconies, able to resist the difficult coastal weather conditions.

While the beach setting provides the 36-property development with a spectacular backdrop, it also presented many challenges due to problematic climate. With the roof and balconies needing to guarantee a long-lasting result, Sika Sarnafil and Sika Liquid Plastics systems were specified for the job, working together seamlessly to create the desired result for the project.

Progressive Systems, a leading roofing contractor in the south west, was tasked with carrying out the installation. Having worked with Sika before, they suggested Sika Sarnafil single ply membrane for the roof, as the adaptability of the material would be durable enough to resist the elements, with a look to equal the prestigious coastline location.

Wind uplift calculations were provided by Sika Sarnafil to the contractors, which suggested the product be mechanically fixed to ensure the roof was able to resist the formidable weather. With a combination of Sarnafil’s S327 18 EL Lead Grey single ply membrane, plus Sarnavap vapour control and SarnarTherm insulation, the outcome was a robust roof that met the requirements of the project.


For the balconies, a Sika Liquid Plastics system was suggested to provide a complete watertight solution. With the installation handled by Western Flat Roofing, a Sika Liquid Plastic’s Quality Assured (QA) contractor, they chose to use Sikalastic 625 grey (PU), cold applied system with self-adhesive on a tapered insulation scheme, creating seamless and durable waterproofing on the balconies.

The project and its location presented many opportunities to problem solve for both contractors and Sika. When installing Sarnafil’s single ply membrane health and safety was top of the agenda – in fact, the disruption caused by strong winds even resulted in aborted site visits on occasion. On the balconies, the installation of three-ton hot tubs meant the insulation scheme had to be designed to allow water flow around the fixed structure, while complying with the correct U-value and withstanding the weight. However, regular visits from Sika’s Field Technicians meant queries were handled directly and quickly resulting in a successful installation and securing a 20-year guarantee for all Sika products used.

Alistair Speirs, Area Technical Manager at Sika said: “This build presented many challenges because of its positioning on the coastline and the difficult weather. However, the combination of Sika products along with the expertise of both the contractors and our technicians involved in the installation, meant the project was completed on time and within budget. We are all thrilled with the result in terms of the durability and the stunning aesthetic.”

The coastal conditions will be no match for the resilient solutions created by Sika, expertly installed across the roof and balconies to keep the residents of The Dunes warm and dry for many years to come.
