Spray foam insulation can be relatively more expensive than traditional insulation methods, but this is because it is a premium product. There is a high initial cost; however, spray foam insulation will actually save you money in the long run.
This is because it stops your heating from leaking out of your home and consequently can save you up to 50% on your energy savings per month.
Underfloor insulation prevents heat loss through your floorboards, so it may be a good idea to have spray foam installed under your floors to prevent heat loss in the winter. You will notice a significant improvement in your home after installation, particularly if you have wooden floorboards.
In the winter, wooden floorboards can be extremely cold to walk across, but after insulation installation, you will notice that your floorboards will not be as cold to the touch as they once were.
You may be tempted to try some DIY underfloor spray insulation. Still, it is advised that you find an accredited insulation installer, as they are professionally trained in insulation installation and will not make any costly mistakes.
