Grey EPS Insulation Board
Product code 8404
Carbon-enhanced grey EPS board for roofs, walls and basements; 0.031–0.032 W/m·K.
EPS is an insulation board made by expanding polystyrene beads and bonding them together in a mould; this one has added carbon. It goes on roofs, walls and basements. An insulated building needs less heating in winter and less cooling in summer, so running costs drop, and burning less fuel means less pollution.
