Note on Foam Thickness

Due to the natural structure of closed cell foam, the material can vary slightly in thickness along the length of the roll. This is completely normal for this type of insulation.

Our 25-30 mm foam is manufactured using a heat-expansion process, which creates millions of tiny sealed air cells inside the material. During production, rolling, and compression for transport, some areas may compact slightly more than others. Because of this, you may measure sections as close as 25mm and other areas as much as 30mm.


Fixing Methods:
Adhesive, Double-Sided Tape, Star washers.
