Heat lost through wall surfaces can add up to annual energy losses of 40%. Optimum thermal insulation from Neopor® GPS insulation is the practical way to stop such losses. Exterior walls are the first and best places to save money through insulation. Neopor® GPS insulation efficiently insulate buildings from either inside or outside. Thermal insulation composite systems work well for exterior walls and core insulation for cavity masonry. When exterior insulation is impossible, impractical or undesirable - to save a façade, for example - interior Neopor® GPS insulation works quite well. For new construction, Neopor® GPS is appropriate for almost any type of wall.
