Heat is given off by all objects in your home if the surfaces around you are colder than you, heat will transfer from you to them and if they are warmer than you, they will give heat to you.
This is one of the reasons why people find underfloor insulation so effective. The reports from our clients show that they never expected it to make such a huge difference to the comfort they feel in their home.
Uninsulated Floors
If you have an uninsulated floor void exposed to cold outside air, this will lower the temperature of the floor. With such a vast surface area, a cold floor draws radiated heat from the body. This effectively sucking the heat from you. Insulating the floor void and raising the temperature of the floor boards you can reduce this radiant heat transfer. Heat exchange happens faster at higher temperature differentials, raising the temperature of the floor by just a few degrees can slow the transfer of heat between yourself and the cold floor boards.
Don’t blame the air temp…
Have you ever noticed when winter comes you reach for the thermostat, cranking it all the way up to 25c. Yet on a hot summers day, there is nothing better than sitting in an air conditioned room at a chilly 16c. This has a lot to do with radiant heat and shows that air temperature is not the only factor at play when trying to reach a comfortable temperature within your home.
All this comes into play on top of the other benefits you get for adding underfloor insulation, like eliminating draughts that come up through gaps in floorboards or around openings for pipes and wires.
Cavity wall insulation is another great example of the importance of radiant heat transfer.
