Product Description

Ubiflex B3 lead alternative flashing can be used in applications where lead is traditionally installed but, Ubiflex has no re-sale value as scrap. Manufactured from a modified polyethin compound and an aluminium mesh reinforcement. Traditionally used to provide a weatherproof junction at features such as a change of direction and materials, Ubiflex B3 is environmentally friendly, non-toxic and recyclable.

80% lighter than lead and 50% quicker to install, Ubiflex B3 has handling, structural and health and safety advantages. Ubiflex B3 is fully malleable, can be worked in both directions and is self-sealing if punctured. Ubiflex is not susceptible to thermal movement, this allows aprons up to 12m long to be formed without seams or expansion joints which means there is less wastage than with traditional materials.

Ubiflex B3 is also BBA Certified and is also approved by the NHBC (National House Building Council) and Zurich insurance.

To ensure Ubiflex Lead Alternative Flashing is installed correctly, please use Ubiflex High Tack Sealant.
