A guide that will show you how easy and simple it is to make a fireplace casing using VARMSEN calcium silicate boards. VARMSEN boards are more than just fireplace insulation. The traditional solution involves making a fireplace casing based on GK boards and using mineral wool as an insulator. VARMSEN combines these two elements in one board. It can be a structural element for the flue casing while being an excellent insulator. It is ideal for insulating beams, side walls and the wall behind the fireplace, which makes it a universal solution. www.timkominki.pl // 604-666-661
