U-value as low as 0.4W/(m²·K). A 8.3 mm thick LandVac has better thermal insulation effect than the 1.5m 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.
