Our door adopts high-standard air-tight structure.
All around seal rubber: We use seal rubber strip on the door leaf. Such special shape rubber can break the cold-bridge and reduce
heat transduction to minimum level.
And we add extreme cold-resist chemical into raw material,making the seal rubber very soft
even in -30ºC low temperature.This will make sure of high-airtightness.
