All Platinum Series Insulation® is made from extruded polystyrene foam. When properly installed over old siding, it provides a continuous layer of thermal and air infiltration protection.
This extruded polystyrene underlayment provides improved R-value and a solid, level base for new siding. A clear plastic film laminate provides strength at the “cut and fold” hinge so that the panel lays flat against the wall.
This extruded polystyrene foam insulation board features shiplap edges for a tight fit and improved energy-efficiency – up to 3.8 R-value. The interlocking sheets provide a continuous layer of thermal and air infiltration protection.
