What is Underfloor Insulation?

If you live in Australia, you may already know that underfloor insulation is a must. Given the often harsh and volatile changes in our climate, we need to ensure that the living conditions in our homes are protected from external weather conditions.

Underfloor insulation offers thermal efficiency in your home and creates a comfortable environment for all those living in it.

Benefits of Underfloor Insulation

  • Underfloor insulation prevents a large amount of heat from escaping from the floor
  • The best underfloor insulation solutions can drastically reduce the cost of your energy bills
  • After reducing the amount of time you run your energy appliances, you will reduce your carbon footprint
  • Underfloor insulation provides a degree of soundproofing to any property in which it is installed
  • Foilboard underfloor insulation is completely non-toxic and safe for installation and use
  • Protection for your property from external weather conditions.

How Does Underfloor Insulation Work?

If you are interested in understanding how underfloor insulation works and finding how to insulate your underfloor–look no further.

You can either install underfloor insulation panels when you are in the construction phase of a building, or you can retrofit underfloor insulation in an existing property.

A certain amount of heat escapes through the floor, while cool air tends to pool down there. By installing underfloor insulation you are keeping the desired air in and the undesired air out.

A great advantage of this is that the underfloor insulation cost is quickly recouped after installation, as once your home is well insulated—you tend to stop running your heaters and coolers so much.

How to Install Underfloor Insulation?

The exact process of underfloor insulation installation will depend on whether you are fixing it into a building under construction, or existing property.
