Thermal Bridging Explained

On passive projects especially the subject of linear thermal bridging is a very important one, and a greatly reduced amount of heat loss around the perimeter of the building is vital in order to achieve good SAP ratings. EcoRaft Double L does this by separating the inner leaves of the wall from the outer leaves. All using the specially designed perimeter elements.

Eco Friendly Foundation

The EcoRaft Double L is the perfect foundation for those looking to minimise energy bills due to its ultra low slab U value and low linear thermal bridging.
