Bungalows can be difficult to treat and make energy-efficient. Their foot print is larger than an average house which means that it has more surface area which is exposed to the cold outside space. Homes over multiple floors may have the same size footprint, Bungalows will have double the roof and double the floor of a two storey dwelling.
Cavity wall insulation
Because it was built in the sixties it had cavity walls, suspended floors and a pitched roof with minimal insulation. The windows were standard PVC double glazed, but two of the front windows were bay windows which had timber supports underneath and moulded trims above.
Suspended timber floor
The homeowners were aware of cold spots and condensation around the property, and thermal imaging of the home had reveal poorly installed cavity wall insulation, mould growth around the windows and large drafts coming up through the floor.
Triple glazed windows
Our solutions for these problems were to replace the windows with triple glazed units and to rebuild the bays, adding insulation above and below.
This will improve the energy efficiency of that element and reduce the cold spots and condensation around the windows and in the bays.
We also insulated under the floor ensuring a good deep layer which should eliminate most of the drafts. Due to space constraints putting and airtight layer in was impractical.
The final stage of the work was to improve the roof structure and the bungalow and remodel the living room. This work brought light into the living room and made it the cosiest room in the house.
By improving the insulation and the windows we also managed to lower the draughts. The homes air tightness was tested at the end of the process.
