External Wall Insulation:

Insulated with 140mm Frametherm 34 on the inside of the studwork & 50mm Omnifit between the service void. Wall U-value – 0.15 wm2k

Internal Wall Insulation

Insulated with 100mm Omni Roll Acoustic between studs to provide great acoustic values.

Ceiling Insulation

Insulated with 200mm loft wool insulation fitted in between joist and 200mm loft wool above the joists. Overall ceiling U-value 0.11 wm²k.

Airtight system

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.

Service batten

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
