Cavity Wall Method
Using a traditional block cavity wall method it is possible to achieve a very low energy standard. One such method would be a 250mm wide cavity pumped with high density insulation bead. Along with using a wide cavity, low conductivity wall ties known as (Ancon Teplo) can also be applied. Below are some images shown cavity walls under construction using these ties. Given the total wall build up is 450mm wide the leafs are brought up separately. To break cold bridging at the eves, a double wall plate is used one on each leaf with the rafter tying leafs together. Double wall plates will also allow for a continuos flow of insulation with roof. On all internal walls, one row of quinlite block will minimize the cold bridging rising from raft foundation.
