Ubiflex is a non-lead waterproof flashing material which can be used in most applications where lead is traditionally used, to provide a weatherproof junction at features such as a change of direction and materials. Ubiflex is available in a range of colours, widths, lengths and accessories for installation. Ubiflex has a number of USP’s, which differentiate it from other non-lead flashings and make it the preferred choice when considering replacing lead. It is environmentally friendly; non toxic & recyclable, much lighter than lead and extremely easy to handle, doesn’t stain like lead, has BBAcertificate, has BRE wind tunnel test certificate (Ubiflex didn’t fail at 110 mph) and Ubiflex B3 guaranteed for 25 years.
