U-value as low as 0.4 W/(m2·K). A 8.3 mm thick LandVac has better thermal insulation effect than the 1.5 m thick brick wall.
Thanks to the high vacuum chamber of LandVac, which effectively blocks the thermal transmission, the thermal insulation performance of LandVac is 2-4 times better than insulated glass and 6-10 times better than single pane glass. The properties of this product meet all international thermal transmittance requirements on windows and doors for passive houses.
