Conserve Underfloor insulation
Underfloor insulation is another thing that will help to reduce your heating bills. If you put insulation under your ground floor floorboards you will save yourself approx £60 a year and will not have to tolerate nasty cold drafts.
Older houses normally have suspended timber ground floors so if your home falls in to this category, you will be able to insulate these by laying mineral wool insulation supported by netting between the floor joists. If you have a cellar or a basement under your ground floor you can often insulate from beneath as this will save you having to lift all your floorboards. Unfortunately not all homes have a cellar so if you do need to take up all the floorboards to insulate from above, it may well be prudent to employ a professional, as care will need to be taken as not to damage the floorboards.
Newer homes tend to have solid concrete floors and these can also benefit from insulation. A solid concrete floor will require sheets of rigid insulation to be laid over the top of the concrete and then a layer of chipboard put on top of that. Unless you are a very experienced DIYer this job is best undertaken by a professional as doors, skirting boards and even electrical sockets may need adjusting to compensate for the new increased floor height
It is possible to insulate a solid floor yourself but you will probably require an carpenter to adjust your doors and skirting boards and an electrician if you need to move electrical sockets up. These factors make solid floor insulation less cost effective than suspended floor insulation.
Underfloor insulation Advantages
- Because your floor is warmer and there are less drafts, you will be able to lower your heating temperature thus saving yourself money
- reduce your home's carbon footprint
- floor will feel warmer and more comfortable
- improve your home's energy efficiency rating
Underfloor insulation Disadvantages
- Lifting up all your floorboards will cause serious disruption
- If rigid foam insulation is laid on to a concrete floor this may raise your overall floor height so you may have to adjust doors, skirting boards and electrical sockets.
- If you need to get in a professional to complete the job it will take you quite a long time to recoup your initial cost.
