The Frinorm type SPK thermal insulation board has very good thermal insulation properties. Expanded rigid polystyrene foam (EPS), 15 kg/m³, is covered on both sides with thin chipboard E1 P5, 3.5 mm. The visible side is coated with a washable, pore-free and non-exuding plastic foil. One of the long edges is reinforced with a massive wood edge band, which makes the board especially stable. The circumferential groove and tongue joint, covered with a white plastic H-profile rail, ensures joins without thermal bridges. It is installed on a wooden structure, and the boards are attached invisibly in the groove with screws or nails. The large-sized elements ensure fast installation, and processing on site with standard woodworking machines is uncomplicated. The invisible screw connection, the white surface and the board joins covered with H-profile rails give the finished walls a light-coloured and appealing appearance.
