25mm Celotex TB4025 Insulation Storage & Handling

If you need to store 25mm Celotex TB4025 insulation boards for a while before installation, you should choose a cool, dry space.

Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, store them on a level surface and under a protective cover.
