Hidrostan Out/Permaroof (UK) Limited EPDM Facade Membrane — fire risk

Hazard

The product is marketed as Euroclass B, but there is no evidence that it could consistently achieve Euroclass B for reaction to fire performance. The product therefore may not perform with the declared reaction to fire performance required or be suitable for its original desired application. The product does not meet the requirements of EU Construction Products Regulation 305/2011 as they apply in the UK.

Remedy

Permaroof (UK) Limited, importer of the EPDM façade membrane, with declared performance of Euroclass B for fire performance, notified the two distributors in its supply chain of the product not meeting its declared fire performance. Distributors Dortech Direct Limited and BuildmasterUK Limited have notified their affected customers directly. Businesses who may have purchased this product and not been contacted by Dortech Direct Limited and BuildmasterUK Limited should contact the distributor directly. The potential impact of lower performance of a product in relation to reaction to fire and building safety will vary on a project-by-project basis and will depend on factors unique to each building. Where already incorporated, building owners should seek advice from their building safety officer, an independent inspector, fire safety officer or a relevant building control authority, as appropriate, and consider reviewing the building’s fire strategy if necessary.
