How to Cut Thermafleece CosyWool Roll: Although tearing thermafleece to fit is self-explanatory, cutting Thermafleece accurately is always a good topic for a discussion.
Roll and Cut Method: Tools Required: Sharp Scalloped Edge Knife or Insulation Saw
FOR AN ACCURATE LENGTH: If you have a slab or a roll and want an accurate length, take the insulation and roll it as tightly as possible along the width. Measure where you need to cut to give you the length you require. Taking the insulation saw / knife easily cut through. This provides a nice, neat edge and is an alternative to tearing by hand.
TO CUT THE WIDTH OF THE ROLL: Keep the insulation rolled and do not unwind. Measure the required width that you need then using the knife or insulation saw begin to cut through the whole roll.

Compressing between boards: You can also cut Thermafleece by tightly compressing or clamping the insulation between two pieces of solid 15mm board. Overhang the fleece where you want to cut keeping the two board edges aligned. Saw cut the edge using a sharp, scalloped edged knife and keep the blade firm and square against both board edges throughout. Trim any fine remaining fibres with large scissors or shears.
- To retain the benefits of water vapour, absorption and release, Thermafleece CosyWool Roll may be used in conjunction with a vapour permeable underlay
Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.
