Bituminous Roof Systems - Bauderflex

When to specify...

Bauderflex is suited to new build and refurbishment applications, and is robust enough to withstand foot traffic and most permanently sited plant. It can be used in warm and cold roof designs and also to overlay existing roofing materials.  Our Bauderflex Roof System features torch-free and safe to torch installation on combustible details.
