Thermal insulation
WIŚNIOWSKI steel doors are also an effective protection against heat loss. Prestigious tests have confirmed the attractive U parameter (heat transfer coefficient) from 1.2 W/m2K. This result is not just a number, but a guarantee of a comfortable temperature and lower heating or air conditioning bills.
Waterproof
Our doors are a watertight product. Tests according to the EN 12208 standard confirmed a high watertightness class of 3A, which means that our doors can be installed without a roof, and its absence will not negatively affect the quality and functionality of the product.
