Due to the methods of installation, Warmcel fills timber frame panels completely, to a high density leaving no gaps or cracks that a cut insulation can create.

This high density fill that you get from Warmcel insulation increases airtightness levels; prevents any convection looping through gaps that could cause cooling and heat loss; prevents overheating and helps to maintain stable temperatures throughout the year.

The complete, high density fill of Warmcel in timber frame houses has consistently shown through testing to increase airtightness by 30%
