Abstract
A polyurethane adhesive having a low gross heat of combustion is used to assemble insulation panels such as mineral wool insulation panels. The polyurethane adhesive contains a polyisocyanate side and a polyol side. The polyol side includes a certain polyether ether polyol and an aromatic polyester diol. The mixture of these polyols provides excellent adhesion together with suitably low viscosities, even at high filler levels, and a cured adhesive that has a low gross heat of combustion.
