Foilboard

Foilboard is a type of insulation that is used to keep buildings warm in the winter and cool in the summer. It is made of a thin layer of plastic on top of a cardboard backer. The plastic layer is covered with tiny metal foil pieces that help trap heat or cold so it can't escape. It also helps keep moisture out, which helps keep the building dry and comfortable. Foilboard is a great way to save energy and help keep your home or building more comfortable year round.
