Underfloor Insulation
We had the Mammoth Insulation guys on-site this week installing all of our underfloor insulation.
Given how well insulated the rest of the house is, we knew it would be irresponsible of us not to use the best possible products, so as not to comprise the thermal integrity of the house, as up to 14% of heat can be lost through your floors.
After some research and shopping around, we eventually settled on Mammoth Multi Underfloor. Before this construction adventure, we knew very little about insulation and thermal performance. But we’ve become pretty well versed in heat transfer and R-values, so it made sense to us that we use this unique, friction-fit system.
As opposed to other products where their insulating properties are compromised when they’re stretched as they get stapled or strapped in the floor cavity, Mammoth Multi Underfloor is a self-supporting form of polyester. You simply cut sections slightly larger than the joist space and squeeze them into position, friction holding them securely in place. This also compresses the fibres and maintains the insulating performance and corresponding R-value.

The insulation is slightly wider than the gaps in the floor joists, with friction all that holds them in place. Making for a super fast installation process and a thermally superior insulation solution.
