The product is designed for installing windows and glazed units and for a wide range of professional sealing, thermal and acoustic insulation work in construction.
Additives developed specially for DONEWELL® foam balance the closed and open cells in the foam structure, which gives excellent dimensional stability together with an effective combination of thermal and acoustic insulation properties.
