The thickness of these doors cannot be beaten as every ISO70 door is double skinned and insulated. Our steel sections are exclusively fabricated in this configuration and filled with an insulating rigid PUR foam core. This construction provides a thickness of =67mm (insulation performance K = 0.34 W/m2K), ensuring outstanding thermal and acoustic insulation. Combined with triple-glazed windows, a double floor seal and a thermo frame set, you have the best thermal performance and weather protection in class.
Optional Thermo Frame Set
Our optional sealing and insulating strip system can be fitted to ISO70 doors to improve heat insulation by up to 15%. This is achieved by optimising the frame along three sides when mounted behind the opening. The entire building’s overall performance is optimised, providing great benefits for the user.
