Product Overview

Engineered for the job it protects.

Manufactured through a high-tech calendering process, Insupro features a non-woven polyester carrier saturated and coated with SBS elastomer-modified bitumen compound. With cold temperature flexibility extending to -22°C, a longitudinal tensile strength of 800 N/5cm, and elongation at break of up to 40–45%, Insupro delivers excellent performance in cold climates and applications subject to significant structural movement or mechanical loading. It is suitable for flat and sloped roofs, foundations, basements, tunnels, wet areas, swimming pools, and slab-on-grade construction in demanding environmental conditions.

Insupro is applied via torch-on installation, forming a continuous, durable bond with concrete, metal, and other prepared surfaces. Its high-performance SBS compound provides long-term elasticity and recovery under thermal and structural cycling, protecting against water ingress and moisture damage throughout the service life of the installation. Available with surface finishes including colored slates, aluminum foil, sand, and polyethylene film, Insupro is a technically advanced SBS membrane suited to projects where robust cold-climate flexibility and superior mechanical performance are essential requirements.

Installation

Application, Step by Step.

01 / 06
01Surface preparation

Clean the substrate of dust, debris and standing water, then repair any cracks or voids so the membrane can bond to a sound, even surface.

02Priming

Apply a bituminous primer evenly across the whole surface and allow it to dry completely before any membrane work begins on the area.

03Membrane positioning

Unroll and align the membrane on the primed surface, allowing the specified side and end overlaps before any bonding takes place.

04Torch-on application

Heat the burn-off film with a propane torch while progressively unrolling, pressing the membrane firmly onto the prepared substrate.

05Overlaps and sealing

Torch and seal every overlap with a rounded trowel, checking each joint to achieve continuous, fully watertight seams across the surface.

06Detailing and protection

Finish upstands, drains and penetrations with reinforcing details, then protect the membrane before backfilling, screeding or tiling.
