Special offer

As part of our insulation and airtight range, we are also delighted to bring you the Wellhofer attic hatch which is pre-insulated and pre-sealed for airtightness. Manufactured and engineered in Germany the unit has been tested to stringent DIN standards to comply with airtightness and insulation requirements. The Wellhofer hatch remains airtight even under blower door test conditions.

  • The airtight seal on the hatch door is maintained by means of a pre-stressed spring which ensures the door remains airtight, even when a blower door test is carried out.
  • The gap between the door and the hatch is sealed with a rubber gasket.
  • This durable seal has been tested against ageing.
  • The Airtight sealing system ensures that no air leakage occurs between gaps at ceiling and frame. This is due to the double sided adhesive tape and Insulation strip.
  • The hatch door is supplied complete with insulation.
