SARNAFIL Advanced Technology is the first and only UK roofing membrane to be Silver Certified in Cradle to Cradle. After receiving a fantastic reception in Europe, where the roofing membrane has been launched to great success, market-leading roofing manufacturer Sika have launched Sarnafil Advanced Technology, a game-changing sustainable roofing solution, in the UK.

Sarnafil AT is the first single-ply roofing membrane to meet the strict requirements of a Cradle to Cradle Silver Certification. Achieving an impressive Gold rating in the sustainability categories of Material Reutilisation and Social Fairness, and a Silver rating overall, the Sarnafil AT membrane is the solution for responsible roof specification.

Sustainability at the Forefront

Sika has made a revolutionary move in the roofing industry by putting sustainability at the forefront of their innovative product development. Producing a single ply membrane without plasticisers, oils, chlorine or heavy metals was a challenge worth undertaking for the Sika team, as they pushed to make a truly sustainable product that doesn’t compromise on quality. The Sarnafil AT membrane is an environmentally-friendly alternative that adheres to Sika’s values of sustainability while forging ahead of the market on features and ease of use.

Sarah Peake, Sustainability Manager at Sika UK commented: “Sustainability is a core value at Sika, and this initiative aligns with our commitment to the UN Sustainable Development Goals; to be precise, the UN-Sustainable Development Goal (UN-SDG) 12 (Responsible Consumption & Production) and UN-SDG 11 (Sustainable Cities & Communities).

“We have designed Sarnafil AT as a product that can help architects hit sustainable development targets. The Cradle to Cradle Silver Certification proves without a doubt that the membrane is exceptionally eco-friendly, and will withstand any scrutiny drawn from recent legislation like the Government’s Green Claims Code.”


Hybrid Technology

Beyond its incredible sustainability benefits, it is simply a fantastic product. Utilising the best properties of both elastomer and FPO membranes, this hybrid technology combines flexibility and durability with ease of use, ensuring application is quick, straightforward and effective. The membrane is hot air weldable, and features self-adhesive upstands that eliminate the need for solvent based primers or indeed any primers at all.

Sarnafil AT’s ease of use will improve turnaround times for contractors, while the general quality and durability has not been sacrificed at all; in fact, this is Sika’s thickest ever single ply membrane, available in 2.5mm. Dynamic indentation testing proves that Sarnafil AT (2.5mm) features a high-level resistance to impact punctures, making it a perfect solution for today’s fast-paced construction industry.

The introduction of Sarnafil AT is an exciting development for contractors, specifiers, and indeed, the whole UK roofing sector. Its versatility makes it a fantastic option for a variety of roofing applications, while the ease of installation ensures a rapid turnaround for Sika’s Certified Roofing Contractors. The sustainability credentials of the product, which are substantiated by the Cradle to Cradle Silver Certification, only add to what is a very complete package backed up by Sika’s market-leading roofing guarantee of up to 25 years.
