It goes without saying that along with the appropriate passive house windows, a passive house property also requires doors with corresponding heat transfer coefficients. The surface temperatures of the doors must be high enough so that heat from the sunlight doesn’t simply escape and downwards draughts of cold air don’t occur in the area in front of the door. The medium heat transfer coefficient R-Value according to EN 10077 of 0.8 W/ (m²K) must be complied with. Please withdraw the exact test values and measured results of our doors and products from the test reports (PDF).
