The best insulating door on the market

The NASSAU 8000 Extra Insulated Door is the best insulating sectional door on the market for several reasons: the U-value is more than twice as good as standard sectional doors due to the 82 mm thick door leaf, giving it a show-stopping U-value of 0.43 W/m2K - this translates into immense insulation, a reduction in energy consumption of up to 70% and a huge saving on your heating bills. Environmentally friendly in its multi-functional design, the NASSAU 8000 is an energy-conserving sectional door that supports the UN’s sustainable development goals as well as your operations.
