Double sealing strip - no cold bridges

The insulation; the two sealing strips in the frame and a construction of trapdoor without wood prevent heat loss. The 2 sealing strips provide an extra tightness, which means, among other things, that the loft ladder have no cold bridges. It provides a good saving on the heating bill compared to traditional loft ladders. DOLLE clickFIX® 56 PRO is insulated with 50 mm expanded polystyrene (EPS) standard U-value: 0.64 W/m2*K. If the model is extended with a top casing and lid, the U-value is reduced to only: 0.56 W/m2*K. (This U-value is calculated). The low u-value is particularly remarkable, as all the products have been tested as a building component similar to doors and windows. Usually, u-value indications are given as a calculated center value for the trapdoor, which is misleading in connection with energy calculations. The loft ladder have been tested at the IFT Rosenheim Institute for both U-value and air tightness.
