It is an excellent insulating medium which exhibits consistent thermal performance over the range of temperatures normally encountered in buildings. The material is versatile, light in weight, clean and easy to handle, and provides a cost-effective means of including permanent insulation in floors, walls and roofs to meet, and exceed, the standards laid down in the building regulations.
