Underfloor Insulation

Why insulate my underfloor?

  • Reduce a further heat loss of approximately 25%
  • Energy costs reduce
  • Noise reduce

So, you’ve got your ceiling insulated, and are wondering if you should insulate under your underfloor also? In terms of heat loss, carpeted floors account for approximately 15%, but raised floors with exposed floorboards lose about 22% of heat. This figure increases to approximately 30% if you also factor in air droughts in floorboards. Given that ceiling heat loss is approximately 35%, you should strongly consider underfloor insulation if you have exposed floorboards on a suspended wooden floor.

Underfloor Insulation

Insulpro Underfloor insulation is typically done by using R2.5 Earthwool batts that are placed securely between floor joists, and then supported with straps and staples.

Not all houses are able to have underfloor insulation. Houses with suspended wooden floors with adequate cavity / crawl space and Houses with bare wooden boards or only thin coverings would benefit from underfloor insulation, especially if the wind is able to blow under the dwelling.

Floor covering, such as thick carpet with underlay, provide a degree of floor-based insulation inherently, but will still benefit from a thick layer of insulation sub-floor (about 10 times thicker than underlay and carpet combined thickness).

Underfloor insulation will not only make a dramatic difference to your home’s temperature, but also your heating bill noise reduction and your greenhouse gas emissions.
