Insulation barely affects energy efficiency in your home

It is unwise to laugh at your neighbours that use towels to cover the gaps in their doors to prevent heat from escaping or who have invested their savings in double glazing.

Choosing good insulating materials and sealing gaps could save you a considerable amount on your energy bills. You have to make sure that no warm or cool air can escape through gaps in the building (doors, windows, roof, floor, walls). If you have already changed your windows, you will be recovering your initial investment every month. If you have not done so yet, now is the time to do it. According to the Organisation for Consumers and Users, you could save 20% on your electricity and gas bills. Which are the best? Some windows now come with an energy rating, which makes buying much easier. The OCU also recommends PVC window trims and glass with a minimum depth of 4 mm.
