50mm Celotex Insulation Storage & Handling

As they are super light and portable, 50mm Celotex boards can also be handled and transported easily; making them a doddle to install. If you need to store 50mm Celotex 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, pop them on a level surface and under a protective cover, just for good measure.
