The Benefits of Underfloor Insulation

It is estimated that over 1 million homes in New Zealand have little or no underfloor insulation, and poorly installed insulation is responsible for over 10% of heat lost through the floor. Installing underfloor installation is a cost-effective solution to preventing heat loss, reducing dampness and creating a warm, healthy home.

Book Your Underfloor Insulation Assessment

Not all floors are possible to retro-fit underfloor insulation after they’ve been built, which is why we offer a free home insulation assessment to take a look and discuss the best solutions for your home or building.

Our trained assessors will take a look under your floor to determine what kind of insulation is currently installed and its condition, plus access to the crawl space. They’ll discuss the best solutions for your particular situation and budget.

Installing Your Underfloor Insulation

How your underfloor insulation is installed can make all the difference as to how well it actually performs. It can be a hazardous job and dangerous if not done correctly.

The EnergySmart team of expert insulation installers are trained and experienced to do the best job insulating your home. They will use their expert knowledge to bring your underfloor insulation up to standard, a more time and cost-effective solution than DIY installation.
