Superior high strength is the unique safety point of the new Spirtech 250 vapour-permeable underlay in the Redland range of Lafarge Roofing, because it is specially designed with the roofer's safety in mind.

No other underlay is known to have passed any tests for this level of safety in Britain, despite the ever-increasing focus on health and safety on building sites.

Currently, Britain does not have any industry standards for this aspect of safety. Germany does however and they're the highest standards in the world, which is why their test for step-through safety was used to develop Spirtech 250.

“There is an ever-increasing focus on health and safety on building sites. Nobody wants a roofer to be the victim of falling through the underlay, so it's alarming that Britain has no industry standard for such a hazard,” said Accessories Sales and Marketing Manager for Lafarge Roofing, Richard Hartley.

“We certainly weren't going to wait for such standards to be introduced in the UK, so we applied the best safety standards in the world – and those are the industry standards of Germany.”

The high-tensile strength of Spirtech 250 makes it easier to work with too, because it is so resistant to tears around nails.

Thanks to its durable construction, Spirtech 250 is also exceptionally abrasion resistant, so will not get damaged by foot traffic.

If it doesn't tear, this means not only is it safe, but there is no risk of damage while being fitted – so no time is wasted replacing damaged sheets.

Spirtech 250's exceptional strength comes without any compromise to the light weight of non-bituminous underlay, as each 50m-length roll weighs in at just 11.4kg. One roll is wide enough to cover a 75m 2 area.

Richard Hartley sends a personal message to all roofers “Take a look at Spirtech 250 and you'll see it answers every need to get the job done very quickly without any of the inconvenience that you may experience with bituminous felt, and be safe in the knowledge that it is covered by Lafarge Roofing's unique 15-year guarantee.

Spirtech 250 is available at all branches stocking the Redland range of Lafarge Roofing.
