Description
INSUPRENE is an elastomeric Modified Bitumen Membrane used for various waterproof
applications. It is manufactured in a high-tech calendaring process, which involves the
saturation and coating of a polyester carrier with an SBS elastomer-modified bitumen
compound. The SBS modifiers are used to improve the thermal, chemical, and aging
properties of the bitumen compound. Meanwhile, the mechanical characteristics such
as tensile strength, elongation, and tear resistance are boosted by the non-woven
polyester carrier, which acts as a reinforcement to the product.
INSUPRENE – Bitumen Membrane Surface Finish
The lower surface of the membrane is laminated with a thin thermo-fusible polyethylene
‘burn-off’ film. The membrane is available with a wide range of upper surface finish
options including different coloured slates, aluminium foil, sand, and polyethylene film.
