LandGlass recently received the latest and more complete test report from ift. In comparison with the report released in November, the contents of the latest report include also the performance data of LandVac after the thermal shock tests and wind resistance test. The results indicate that after nearly two months of single side thermal shock (heat/cold) tests and dynamic wind load resistance test following European testing standards for windows and doors, LandVac shows no sign of change to its performance and maintains a constant U-value at 0.4W/(m2·K).
Note: Headquartered in Rosenheim, Germany, ift is a world renowned certification body specialized in building materials. U-value (thermal transmittance) is a measure of the heat transmission, representing the transfer of heat allowed through a unit area of a material. The lower the U-value, the better insulating properties the material has.
