Product descriPtion

The bituFLAME® membrane system is comprised of a full range of torch-on membranes used in a wide range of waterproofing applications. The bituFLAME® system may be fully torched, mechanically fixed or cold-applied using a bitumen adhesive depending on the performance required.

Why you should use bituFlAMe®

bituFLAME® has many outstanding product features, making it the ultimate choice when selecting torch-on products. Its superior qualities of tensile strength, elongation and tear resistance sets bituFLAME® apart as the ideal durable solution for your waterproofing requirements.

In particular, bituFLAME® ...

Has high tensile strength and tear resistance.

Has excellent puncture resistance.

Is BRANZ Appraised.

AreAs oF use

bituFLAME® membrane systems are used in a variety of waterproofing applications including;

Flat roofs and gutters

Below ground tanking

Decks and balconies

Podiums, car-decks and ramps

Watertanks

single or tWo lAyer systeMs?

One of the advantages of a torch-on system is that a variety of systems can be used depending on the situation. As long term performance and durability are our over-riding goals, WPS strongly recommend two layer systems be installed wherever possible.

In roofing applications, fully torched single layer systems may only be used on cast in-situ concrete substrates, cast over profiled metal or permanent formwork. In all other applications a two layer system is required.

In below ground tanking applications, a two layer system is also recommended as it provides greater protection against mechanical damage by steel fixers and other trades.

It is important that light colours only are used. Colours with a low light reflective value (LRV) i.e. less than 40, should not be used as the substrate will draw too much heat and cause substrate movement.

Water must not be allowed to pond on the surface of any duroTUF® coating.
