FIX-R PVC MEMBRANE SYSTEMS

FIX-R PVC is a hot air welded solution for your flat roof that is available in both a mechanically fixed and a bonded system.

PVC membrane systems offer a waterproofing solution that leaves more design flexibility for specifiers. Suitable for both new build and refurbishment projects, installation of our FIX-R PVC systems involves no gas torches. With the usage of gas torches on roofs becoming more restricted, PVC membranes have gained in popularity. They are now widely used in a range of sectors, including education, hospitality, commercial, healthcare, and residential buildings.

FIX-R PVC Mech Fixed system is suitable for roofs where the substrate doesn’t allow for adhesives used on a Bonded system. Suitable for use on a range of substrates and deck types, such as minimum 18mm OSB3 & Class 3 Plywood, Institu Concrete, as well as metal decks as part of a warm roof build up or where the deck has been overlaid sheathing board.

Traditionally, our FIX-R PVC Mech Fixed system is used for larger projects and can be installed in a warm or cold roof application, year-round and widely regarded as faster than adhered PVC Membranes.

FIX-R PVC Bonded system adheres the PVC membrane directly to the roof deck using the FIX-R Bonded Membrane Adhesive, which is fully bonded
to the substrate. Due to optimum curing times in warmer temperatures, adhered systems are more suited to warm weather conditions to allow for an efficient install.
