NK4 Warm

Champion Door offers many different alternatives for industrial installations and commercial properties, always taking into account the special circumstances of each doorway.

The tight structure of the NK4 Warm door saves energy and increases employee comfort by preventing draught. NK4 Warm industrial door is a 2-ply fold-up partition like NK2 Double, except that two additional insulation layers for heat and noise insulation have been attached. NK4 Warm’s R-value is 7,99 ft² °F h/BTU and even up to 9,96 ft² °F h/BTU with additional insulation. Good thermal insulation, minimal condensation of moisture on the door surface makes the door highly reliable even in Arctic conditions.

NK4 Warm’s functional applications include aircraft hangers, shipyard halls, bridge crane openings and factory sheds. NK4 Warm’s excellent sound level attenuation properties also make it an excellent choice as an interior space divider. The doors are nearly maintenance-free and can be equipped with thermal insulation, soundproofing and burglary protection. No size limitations.
