Timberframe Supply and Erect and of a New dwelling in Ballymoney Co Antrim
Kilbroney Timberframe LTD supplied and erected the Timberframe for this project in April 2013
Kilbroney Timberframe have provided a home which is extremely easy to heat and have low energy bills. We achieved this high standard using passive design techniques.
External wall Insulation
Insulated with 150mm Fibre wool and 40mm PIR rigid board fitted on the inside of the studwork. Combined with are air tight metalized reflective membrane this gives us a overall wall u-value of 0.15 wm²k.
Internal Wall Insulation
Insulated with 100mm fibre wool to provide great acoustic values.
Sloped Roof Insulation
100mm PIR rigid board insulation cut and fitted in between rafters. 40mm PIR rigid insulation fitted on the face of the rafters
Insulated with 150mm loft wool insulation fitted in between joist and 150mm loft wool above the joists. 25 MM PIR rigid boards fitted below joists. Over all ceiling U-value 0.12 wm²k.
We used a metalized Reflective membrane on all are external walls and ceilings. By taping the over laps with metalized tape and sealing around doors and window with Siga Corvum window tape. Using these products and a high standard of workmanship we received a 1 in the buildings Airtight test.
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.
Heat recovery system
After getting the top rating in the airtight test we decided to fit a Heat recovery system in order to retain 90% of all heat loss, control levels of condensation and provide fresh filtered air constantly.
Windows and Doors
To match are highly effective timber frame walls we fitted future proof Black double glazed PVC windows which have a U-Value of 1.2 wm²k. With a black aluminium bi-folding door and a black aluminium sunroom screen.
