Underfloor Insulation

Reduce your heating bills, cut out draughts and enjoy walking on warm, properly insulated floors thanks to underfloor insulation from Sprayit Solutions, Melbourne.

Heat rises, which means the problem of cold floors isn’t going to be solved by merely turning up the thermostat. To get to the heart of that problem, think underfloor insulation. What’s more, to get the right floor insulation, Melbourne customers look to Sprayit Solutions. Here’s why:

  • Our polyurethane spray foam solution (Icynene) is ideal for floor insulation. Unlike traditional insulating materials that have to be fixed in a haphazard way, our products are engineered to totally eliminate any gaps and air leaks as it bonds directly to the floor where it stays for the life of the building.
  • Our floor insulation offers the multiple benefits of lower heating bills, greater noise reduction and a more comfortable space – all delivered
  • through a once-and-for-all solution designed to deliver results throughout the lifetime of your property.
  • We supply underfloor insulation in Melbourne and greater Victoria to residential and commercial customers.

Underfloor Spray Foam Insulation FAQs

Why should I insulate my floor?

Insulating your floor is especially beneficial in Melbourne where weather conditions can change in an instant and reach extremes of cold and hot. Underfloor insulation is an effective way to eliminate drafts, prevent heat loss, inhibit air infiltration, and control the interior temperatures of your property. This will keep not only your floor but the entire home warmer in the winter and cooler in summer. Although some materials are better than others at doing this, having some form of underfloor insulation in your home will notably reduce your annual heating and cooling costs. Some insulation materials also protect your home from moisture, mildew, and mould.

What buildings can underfloor insulation be done on?

Using spray foam for your underfloor insulation is highly adaptable and can be used with a wide range of buildings, so long as there is a minimum of 400mm of accessible space beneath the floor. This method is particularly useful in homes or commercial buildings with floorboards, as it not only ensures excellent insulation but also establishes a complete air seal. This air seal created by the under-floorboard spray foam insulation helps maintain a consistent and comfortable indoor temperature while reducing energy consumption, making it an eco-friendly choice for enhanced energy efficiency.

Is spray foam (polyurethane) better than other traditional underfloor insulation materials?

Yes, spray foam insulation is considered superior to other insulation products. The unique texture and composition of spray foam allows it to expand and tightly fill the entire underfloor cavity during installation. This sets it apart from other structured materials. By filling the floor cavity, spray foam creates an air barrier. This air barrier helps to eliminate heat loss (and gain) through convection. Convection can account for up to 40% of a buildings heating and cooling costs (source: Department of Energy Building America Program). From its fit and strength it will also outlast any other traditional materials.

Why is spray foam more suitable for underfloor insulation than polyester, wool, fibreglass, insulation batts, boards, etc?

Not only does the consistency of spray foam allow it to effectively expand and fill the entire wall cavity, but polyurethane foam bonds to the surrounding building structures during installation. This means that it will stay in place for the lifetime of the building and will not age, shift, or degenerate. This is not the case for other traditional insulation materials.

What does R-value mean? Why is it important?

R-value is a standardised measure of thermal resistance. In other words, the R-value of a particular material reflects its ability to reduce the rate of heat flowing through it. The higher the R-value, the more effective the material is at insulating your property from the heat in the summer, and from the cold in the winter.

As a property owner, it is crucial to understand the basic principles of property insulation so that you can make the best decisions for your home and your pocket.

It is important to note that the R-value number alone isn’t enough to determine the effectiveness of the insulation product. This is because the performance of insulating materials is greatly influenced by other factors such as convection (heat loss and gain through air movement).


How can spray underfloor insulation save me money in the long run?

Insulating your house correctly is one of the most effective ways you can reduce the long-term heating and cooling costs of your home. Thanks to the airtight insulation of our polyurethane spray foam solution, homeowners use significantly less energy to maintain comfortable temperatures in their home, all year-round.

Although polyurethane spray foam insulation may initially seem more expensive than other insulation materials, it is, in fact, the more affordable choice. Spray foam serves as an insulator, vapour barrier, and moisture barrier all-in-one. This means that a single application of spray foam will eliminate the costs of installing most exterior caulking, building paper, and vapour barriers. Moreover, polyurethane foam will stay in place for the lifetime of the building and will not age, shift, and degenerate over time. This means that you will save on the maintenance costs of using other insulation materials, which are notorious for having shorter shelf lives.


Can commercial businesses benefit from spray-on underfloor insulation?

Yes, underfloor spray foam insulation has a range of benefits for all properties. In addition to significantly reducing energy and maintenance costs, our spray foam solution has excellent sound absorption properties which can help control mid-range sound frequencies in and around the workplaces such as offices. Furthermore, commercial buildings that are insulated with spray foam have much better protection against mildew and mould, making the application ideal for a wide range of industries.
