Specifier Review


Sika Sarnafil is encouraging building owners and developers to partner solar technology with a proven, high-performance roofing system to safeguard their investment and maximise a roof’s overall performance.

“More and more owners/developers are looking to capitalise on the energy- and revenue-generating potential of their roof space by investing in solar technology,” says the company’s head of technical, Phil Jarratt. “Therefore, anyone undertaking a new build or refurbishment should consider solar as a viable option. Although the Government feed-in tariff for PV installations over 50kWp could be cut this August pending its review, the proposals will still allow for a typical roof refurbishment fitted with solar PV, and including thermal upgrade, to pay for itself in a relatively short period. However, there’s no point in making the investment in solar without investing in the overall performance and lifespan of a roof – and that’s where we can help.”

With this in mind, the Sarnafil system now benefits from a comprehensive range of solar roofing solutions – from the newly added Solyndra solar system, white solar reflective membrane to the Sarnafil Solar Support Post – as part of its commitment to providing roofing solutions to accommodate most available solar PV and solar thermal systems.

Now a platinum Solyndra solution provider, the company has teamed up with a number of specialist suppliers to ensure its Sarnafil single ply roofing system is fully compatible with the latest solar solutions. This includes an exclusive new working relationship with renewable energy solutions specialist Renewable Resources, further strengthening its solar supply chain, which already spans Photovoltaic (PV), solar thermal and cool roofs.

Suitable for both new-build and refurbishment projects, Phil says Solyndra offers maximum return on investment. “This couples our specially manufactured white solar reflective membrane – which boasts the highest CIGS solar reflectance factor on the market of 95 percent – with cylindrical solar modules. As a result, a Solyndra system is capable of harvesting 360 degrees of sunlight – direct, diffused and reflected – significantly increasing the amount of power generated per square metre of useable roof space compared to conventional rigid flat PV panels. This represents maximum return on a solar investment.”

What’s more, with the Sarnafil system benefiting from a BBA-certified life expectancy ‘in excess of 40 years’, and with guarantees available up to 25 years, customers can be confident their solar investment is protected by a proven roofing solution that offers unbeatable longevity and a strong environmental performance.

“Investing in solar but not the roof as a whole is, quite simply, a false economy,” Phil adds. “But by coupling solar with our market-leading roofing system and ancillary products, you can be sure your investment is secured, is very bankable and adds value – vital given that solar is the world’s fastest growing renewable energy source.”
