Why LandVac is superior in thermal insulation?
update: 2016-05-23 14:29:33share:
Thanks to the high vacuum chamber of LandVac, the heat loss is reduced significantly. Meanwhile, by using high-performance Low-E coating, it also considerably suppresses radiation heat transfer and reduces the U-value of LandVac to 0.48 W/(m2•K). The thermal insulation performance of LandVac is 2 to 4 times better than insulated glass and 6 to 10 times than single pane glass. LandVac meets all international passive house heat transfer requirements on windows and doors in stand-alone applications.
