​MasterSeal 732 AT

APP plastomeric polymer-modified bitumen-based torch-applied waterproofing membrane with non-woven polyester reinforcement

Description:

MasterSeal 732 AT is a plastomeric modified bitumen waterproofing membrane (APP), industrially manufactured by impregnation of the reinforcement with the waterproofing compound-based on distilled bitumen modified with polyolefin polymers, which gives to the compound excellent technical characteristics.

The composite reinforcement, made of nonwoven polyester in combination with fiberglass, conveys good mechanical characteristics, excellent dimensional stability and elastic performance. Shaping of sheets, straightness, dimensional and surface uniformity are accomplished by hot calendering of the mass at hot melt fluid state.

It is a self-protected membrane. The upper surface is coated with coloured slate chips and selvedge slate free at one side for easy welding overlap. The lower surface is coated with a thermofusibile polyolefin film.

Fields of Application:

MasterSeal 732 AT is suitable as top layer in multi-layer waterproofing systems, with compatible membranes, or underlayer of discontinuous roofing.

General roofing, on or under floors, wall constructions, under tiles, are valid examples of the design application of this product. It is not suitable for roof gardens.
