It could be a good move to help you reduce energy bills if your floor isn’t already insulated.
Why do you need to insulate your floor?
If you don’t need it, there’s no reason for investing in expensive floor insulation or if it’s unfitting for your home. In any case, how do you know one way or the other?
It usually depends on your home and what type of floor it has whether you need floor insulation or not:
- Early houses with suspended floors are likely to lose more heat through the floor in effect above a void.
- It usually has less of a problem for homes with solid usually concrete floors, built since the 1930s. Concrete floor insulation can be placed and usually consists of a layer of solid insulation placed directly on the floor.
- To effectively reduce this type of heat loss, the contemporary houses tend to incorporate slabs of polystyrene insulation a few inches
Ways to insulate your floor
This is a relatively easy process, if not you will have to take up the floorboards if you have, you can access hatch that allows you to get into the crawlspace (void) below the floorboards. To hold the glass or mineral wool style insulation in place beneath the floorboards, you will need to use netting or wooden battens.
To fill-in the gaps between your floorboards and between skirting boards and the floor, simply apply sealant or caulking.
For your carpet (beneath) or floor-covering, add an insulating layer
Aim a fiberboard underlay or polyfoam board.
Placing a rug on top of bare floorboards will help block some drifts and keep your toes warm although it’s not going to solve all your problems.
- It may be easier to use batts rather than blanket style insulation or otherwise. Batts usually also have the edge of owning a bit higher R-value. This means the greater the insulator’s effectiveness the higher the R-value. Another thing to be considered is the sheep’s wool for its breathability characteristic.
As floorboards may likely become damp and start to rot, the void below the floorboards will have ventilation grills and these should not be restricted. Floor ventilation is important and this thing should be remembered.
