If you have cold floors, rooms that are hard to heat, or summer heat sneaking up through your floorboards, underfloor insulation may be part of the answer.
1. What is underfloor insulation?
Underfloor insulation is insulation fitted beneath suspended timber floors. It slows heat moving through the floor, so the temperature of the floor is closer to the temperature inside the home, rather than the temperature under the house. That means warmer floors in winter, less heat pushing up from below in summer, and a more stable, comfortable home. It also means that your energy bills will be lower as the need to continue to heat and cool your home will be significantly reduced.
2. Will underfloor insulation help in winter and summer?
It is not just about cold feet. In summer, underfloor insulation can also help reduce heat coming up through the floor, especially in homes with exposed or elevated subfloors.
3. The R Value of Underfloor Insulation Explained
R-value is simply a measure of how well insulation resists heat flow. The higher the R-value, the better the insulation performs – but the right choice also depends on your home, climate and installation method.
4. Is Underfloor Insulation Cost Effective
Wondering whether underfloor insulation is worth it? The answer depends on your home, climate, current heating and cooling use, product choice and whether you DIY or pay for installation. Read more about cost, savings and payback here.
5. Is Underfloor Insulation the same as Underfloor Heating?
No. Underfloor heating creates heat and costs to run. Underfloor insulation does not create heat. Underfloor insulation is passive and has no running costs. It helps slow heat loss in winter and heat gain in summer, so your home holds its temperature better.
Next Step: Can insulation be installed under your home?
That depends on your floor type, access, clearance and what is happening under the house
