50mm Celotex Cavity Wall Board Application

Celotex Cavity Wall Boards are designed for use in partial fill, masonry cavity wall applications. The product itself is specifically made to fit between cavity wall ties. 50mm Celotex Cavity Wall boards are 50mm in thickness. Cutting the board is not required as it fits standard wall tie spacing requirements. This cuts down installation times and therefore makes it a great solution to traditional methods.

50mm Celotex Cavity Wall Insulation Boards are tongue and grooved and are lightweight and easy to install.

The Celotex CW4000 range is long-lasting and extremely durable. When storing 50mm Celotex Cavity Wall Insulation, we recommend that you store the PIR board inside. Furthermore, this is to prevent the effects of weathering. If there is no other option but to store the cavity wall boards outside then keep them raised from the ground to avoid ground moisture. The 50mm Celotex Cavity Boards should be kept out of direct sunlight. If outside, this means they should be either under cover or protected with opaque polythene sheets. Furthermore, adverse weather effects could damage the board and affect performance so correct storage is appropriate. It is also worth noting that all of our CW4050 Cavity Wall boards are brand new. As a dedicated seller of insulation, we are able to offer our best price on 50mm Celotex Cavity Wall Insulation.
