How Does Underfloor Insulation Work?
Naturally heat energy travels from places of high thermal energy (hot air) to places of low thermal energy (cool air) until there is an even temperature everywhere. This becomes an issue on summer days when that hot air begins creeping into our homes. In winter our lovely warm indoor air can quickly escape through gaps in the floor, walls and ceiling, leaving us uncomfortably cold inside. Underfloor Insulation, like insulation in other areas of the home, works to combat the flow of heat so that you can keep indoors at a comfortable temperature. There are several different types of underfloor insulation which each work to prevent heat loss/gain in slightly different ways. Below we will discuss the best underfloor insulation products and how each of them helps you keep your home warmer in winter and cooler in summer.Which Underfloor Insulation Is Best?
The most suitable underfloor insulation will depend on a number of factors specific to your situation. For example, are you retro-fitting under an existing house or building a new home? What is the climate like where you live? Are you planning a DIY or will you hire a professional to do the installation? Some of the most common underfloor insulation products include:Polyester Rolls
Polyester rolls such as GreenStuf Underfloor Insulation are a type of bulk insulation. Bulk insulation works by trapping billions of tiny air pockets in their structure which break up the path of heat, slowing it down. If bulk insulation is compressed during installation it will be less effective.
Glasswool Underfloor Insulation Batts
Glasswool batts such as Knauf Earthwool Underfloor Insulation Batts are also a type of bulk insulation which rely on billions of tiny air pockets to slow down heat flow. Glasswool products are a cost-effective option, made from recycled glass materials.
Extruded Polystyrene (Xps) Foam Boards
XPS foam board insulation has a dense closed cell structure which provides excellent thermal resistance. It can be used in a variety of applications throughout a home and is particularly effective in concrete floors as an under slab insulation.
Foilboard Insulation
Foilboard is a rigid insulation panel which can be used in walls and roofs as well as underfloors. They are made from a fire retardant expanded polystyrene core with a pure aluminium layer of foil on both sides. This provides a thermal break and vapour barrier for superior thermal performance and moisture resistance.
What R-value Do I Need?
The R-value of an insulation product tells you how well it resists heat flow. So a product with a higher value will have greater thermal properties than a product with a lower R-value. For underfloor insulation, we recommend choosing high quality products with an R-value of at least R2.0. Remember the higher R-value you choose, the greater thermal benefits and energy savings you will experience.Does Underfloor Insulation Make A Difference?
Yes, properly installed underfloor insulation makes a significant difference to winter heat loss and summer heat gain in any home. Even if the rest of your home is insulated, the floors can let in air draughts or allow heat to leak out. Underfloor Insulation helps create a more pleasant indoor environment which means you’ll probably be using heating and cooling appliances less often. That’s how underfloor insulation can lead to energy bill savings anywhere between 10-20%! Finally, installing underfloor insulation can provide acoustic benefits by dampening the sound of footsteps. Along with wall and roof insulation, underfloor insulation also helps reduce the transfer of noises from outside to inside your home and vice versa.Need Help Choosing The Right Underfloor Insulation?
