Where very low U-values are required Celotex recommends a two-layer system in order to reduce the racking forces on the fasteners required to fix counter- battens to rafters. Here we explain which product to choose instead and why these changes have come in to place. The use of a single continuous layer of insulation over the rafters thereby eliminates the risk of condensation and avoids the need for ventilation of the rafter space.

When used over the roof structure as insulating sarking, Celotex insulation creates a warm roof structure and eliminates thermal bridging at the rafters, whilst the foil facings, used in conjunction with taped joints, provide an effective barrier to moisture vapour and air leakage.

The board is easy to cut to shape and works in the same way as GA, offering a reliable long-term solution for energy saving. Flat roofs – in ventilated cold roof constructions, installed from inside the building.

The condensation risk also depends upon occupancy and building use. With regard to timber frame dwellings up to 18m in height, celotfx BBA certification assessed thermal performance, condensation risk, water resistance and durability.

The surfaces of masonry walls should be sound and free from loose material; large projections should be removed and holes filled and levelled.

In addition, every attempt should be made to minimise the risk of cold bridging at reveals and where heavy party walls are celotfx to the external wall.
