This is a large Edwardian terrace house that has had a substantial energy retrofit:
- Internal walls have been insulated using 100mm of Diathonite thermal plaster
- The suspended timber floor have been insulated with 200mm of wood fibre insulation, sandwiched between 2 layers of air-tightness membrane.
- The windows have been replaced with timber frame double glazed windows. Utmost care has been taken in the air-tightness of the windows, thanks to specialised expanding foam and air-tightness tapes.
- The roof has been insulated with 80mm of sheep wool insulation between the rafters, and the ceilings are lined with 10mm of aerogel insulation.
- The loft has been insulated with 275mm of sheep wool insulation.
- The cellar has been tanked and the walls have been insulated with thermal plaster.
- We have installed solar PV panels. Future plans are to fit a water butt, and to draughtproof all external doors
The house now has an EPC of B with 89 points
