7 Reasons Why having Underfloor Insulation is Important

Insulating your residential or commercial property is important to improve its thermal efficiency. Inappropriately insulated properties have a lower thermal efficiency creating greater energy requirements to heat and cool. The floor makes up a large part of the external envelope of the project and by insulating, can greatly reduce the temperature variation inside the conditioned space caused by the transfer of heat through the floor. Failing to insulate the floor or under insulating will require an increase in mechanical heating and cooling using more energy and money.

Foilboard underfloor insulation Melbourne is some of the most efficient and effective foil insulation available today. It is cost-effective and goes above and beyond the BCA requirements that insulation needs to meet. Foilboard uses reflective insulation properties of foil and the bulk insulation of EPS to insulate effectively by creating a radiant barrier and a thermal break. These properties increase the thermal efficiency for heat transfer by radiation, convection and conduction.

Here are 6 reasons why having underfloor insulation is important.


1. Improve thermal efficiency

Foilboard rigid insulation panels help to improve the thermal efficiency of the property. Unlike traditional bulk insulation and insulation batts, the Foilboard slim profile makes it ideal thermal insulation and vapour barrier and with its superior thermal performance, it ensures that a continuous ‘esky’ effect applies to the property all year round.


2. Tailor insulation protection

There are various ways to install underfloor insulation panels. Foilboard has installation systems for new build and retrofit. These panels can either be installed between the underfloor joists using Floor saddles for a new build and Flexifast for retrofitting between the joists. Alternatively, the Foilboard sheets can be installed to the underside of the floor joists. Depending on your circumstances and the stage of the build, Foilboard rigid insulation panels have a solution to increase your floor’s resistance to change in temperature.


3. Lower energy costs

During the cold of winter and the heat of summer, the use of heater and air-conditioners to improve comfort can be expensive. It is important the floor is well insulated to prevent draughts of cool air or radiant heat affecting the interior temperature and comfort. Foilboard rigid panels seal the property with a permanent thermal and moisture barrier improving the thermal resistance of the floor reducing the heating and cooling requirements, saving money and our precious energy resources.


4. Choose appropriate R-value

The R-value indicates the thermal efficiency of the individual insulation sheet being used. The higher the R-value of an insulation panel, the higher the thermal resistance. Different homes located in different climates require different levels of thermal efficiency. Some climate zones require a much lower R-value than others. To determine the best insulation for your property, it is always a good idea to consult with underfloor insulation specialists who can assess your home and help you determine the most optimum solution for your needs.


5. No need to re-engineer

Foilboard has been designed to fit into common building designs. This means that the design of the property does not have to be reconsidered or re-engineered. This is ideal for owners who want a quick and easy solution to insulate the property without making modifications.


6. Competitive pricing

In relation to underfloor insulation cost, the rigid insulation panels vary in price according to their R-value and material. It is important to source the right insulation for the application. Foilboard Insulation panels prices are competitive and offer a great return on investment value.

Underfloor Insulation FAQs:

Does Underfloor Insulation Heat Up the Floor?

Underfloor insulation does not directly heat up the floor, but it will assist in keeping the property warm during winter. Insulation reduces thermal loss through the floor by adding to the resistance of the materials that make up the floor.

What R value insulation do I need for floors?

The R value required will depend on your project type and which climate zone the project is in. The R value required can be determined by an energy assessor using modelling software or deemed to satisfy solutions found in the National Construction Code. The higher the R value, the greater the thermal resistance of the product.

What type of insulation goes under floor?

The best insulation under floor is Foilboard rigid panels. Foilboard is easy to install and protects the floor as a moisture barrier. Foilboard can be installed in a new floor between the joists, retrofitted in between the joists with Flexifast or attached to the underside of the joist. This will increase the thermal resistance of the floor and improve efficiency to the home.
