We used DuPont Reflective membrane on all our external walls and ceilings. By taping the overlaps with metalized tape and sealing around doors and window with Siga Corvum window tape.
Once the airtight membrane is completed, we fixed a 50mmx35m batten onto all the external walls and ceilings. This creates a service cavity. This means that no services (Wires or Pipes) need to past through the airtight membrane.
To match our highly effective timber frame walls we fitted cream PVC, double at the back and triple glazed windows and doors at the front which achieved a U-Value of 1.2 wm²k.
Our airtight result was 1.39m3/ch.m2) @50pa
