    Icopal Insulation Spray Adhesive

    Icopal Insulation Spray Adhesive is a single component moisture cured polyurethane adhesive. It contains no VOCs and uses non-flammable propellants reducing the risks associated with pressurised canisters.

    The adhesive is applied using a spray wand, allowing for easy, precise and rapid installation. The spray wand ensures consistent bead size when applied to the deck, reducing wastage and ensuring accurate and secure installation.

    Icopal Insulation Pour Adhesive is a single component moisture cured polyurethane adhesive. It offers a simple and cost-effective method of installation, due to not requiring any additional tools to apply the product on-site. It reduces labour costs in comparison to mechanical fixing of the insulation, due to time saving and the fact that no investment in equipment is required. The adhesive is simply beaded from the can onto the deck at the required coverage rate and the insulation panels laid into the wet adhesive.
