I have just got the energy bills from my first insulation and draught proofing project for www.ecoalex.com and they are excellent:
This was for a four bedroom detached house in Hertfordshire and we carried out the following measures in November/December last year:
- Draught proofed each room around skirtings, windows and other holes
- Added temporary secondary glazing to non double glazed windows
- Installed heavy curtain on front door
- Draught stripped doors and windows
Since then we have added 200mm of insulation in the flat roof of the house whilst building a green roof and also in other hard to access roof areas with the help of a local builder. This should mean we see a reduction in energy over next year as well.
In 2012 we plan to start installing internal insulation in the empty cavities in the walls of the house.
Apart from the energy savings, carbon reductions and money saving the most important thing to the occupants of the house is that the living room is warm and comfortable.
