A major source of heat loss in the home is through the floor. Whether it is a suspended or solid floor if it has not been insulated you could experience problems during the colder months.
Suspended timber floors
Improving your floor can be difficult. But we know of many solutions that can help you improve the situation. One common issue with suspended timber floors is cold draughts coming up from the space below. Add to this the “chimney effect” that many older homes suffer from and you can get left with decidedly cold feet during winter. The depth of the space below your floor and the size and spacing of joists all play a part in what method we would use to improve the comfort of your home. Our customers often report significant improvements to their comfort once we’ve insulated their floors. It is of great benefit to their comfort and they often see a reduction in energy used to heat the home.
As part of a whole house strategy, improving the insulation levels in your floor can be the first step towards a modern, low energy, high performance, comfortable and attractive home. Older homes are more likely to have suspended timber floors. Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. Many homes – especially newer homes – will have a ground floor made of solid concrete. This can be insulated if it needs to be replaced, or can have rigid insulation laid on top. If you are replacing at least half of a floor then you have to insulate to these standards whether you planned to or not. Only 10% of heat produced by your boiler goes through the floor. This is mainly because heat rises and exits through the roof instead. However the floor is crucial in this process and if heat is exiting through your roof, new fresh and cold air can enter via your ground floor, if it’s a traditional suspended floor.
How is it installed?
There are a few different methods of installing floor insulation. Normally it can be accessed from a hatch and all the insulation is taken through this hatch and installed from underneath. If you have a cellar, we can remove the ceilings and install from the cellar, this is the easiest way to install floor insulation.
In some instances the joists can only be accessed from above, in which case we would have to remove the floorboards and then replace them once we had finished installing the insulation. In all instances we can help with clearing any rooms that need clearing and storage of any items during the installation.
