Soprema UK adds to roofing range with Alsan 601 wet-on-wet membrane


Soprema UK, the specialist in roofing, waterproofing and insulation solutions, has added to its wide-ranging roofing systems with the launch of Alsan 601; a wet-on-wet polyurethane cold-applied liquid roofing system.

Developed to enhance the choice and variety available to specifiers and contractors from the trusted Soprema brand, Alsan 601 builds on the versatility of the company’s roofing range, which includes PMMA liquid-applied systems, bituminous membranes, hot melt and single ply. The new system will be available through Soprema’s UK-wide distributor network, enabling contractors to benefit from local supply chains, while specifiers can benefit from Soprema’s usual high levels of technical support and advice.

With a BBA-accredited service life of at least 25 years, Alsan 601 will carry a 20-year Soprema warranty and cures to form a durable, seamless, waterproof roof covering that eliminates any risk of water tracking below the surface.

The Alsan 601 system has been developed with ease, speed and convenience of installation in mind, with smaller 10 litre tins available for minor works, along with standard 15 and 25 litre sizes. The liquid membrane provides flexibility of cure rate to suit installation conditions, with use of an accelerator reducing cure time to two-four hours. The accelerator also allows the system to be installed at temperatures as low as 0°C, making it ideal for projects delivered during the winter months.

Alsan 601’s viscosity can also be adjusted in response to application requirements, with an additive available within the range to enable installation on vertical surfaces and upstands.

Available in a choice of two shades of grey, the liquid membrane is used in combination with a glass fibre reinforcement fleece, which breaks down as a homogenous component of the system during installation for a smooth roof finish.

Roland Jackson, commercial director of Soprema UK explains:

“Soprema is a trusted roofing brand for both specifiers and contractors and the launch of Alsan 601 means that we can offer any roofing technology within our BBA approved range. Our in-house technical team is able to support specifiers and help them make the best choice of system for their project, which sometimes includes combining more than one Soprema technology on a single specification.

“Alsan 601 is ideal for contractors who prefer a wet-on-wet liquid applied membrane, for projects where the versatility of a controllable cure time is important or projects that have to be installed without interruption, even during periods of cold weather.”

Like all Soprema roofing systems, Alsan 601 will be supported with a full installation training and approved contractor programme, along with technical support and warranties.
