How to Use Spray Foam to Regulate Your House's Temperature

Proper insulation must be installed in your home to maintain a consistent temperature. By doing so, your HVAC system doesn't have to work extra hard to keep one end of the house cool while the other turns into a winter wonderland.

Fibreglass, cellulose, denim, and other insulation materials are available for homeowners and businesses to choose from. However, spray foam insulation is one of the best choices for a more robust product that can work with only half as much insulation installed.

Types of Spray Foam

High-Density Spray Foam

This type is intended for roofing and exterior walls. High-density spray foam is a type of insulation that uses incredibly high pressurized water to create a barrier between the inside and outside of the structure.

The high pressure causes the water and foam to expand, creating an incredibly effective insulating layer. The layer can be as thin as 1/4 inch, which means it can be used in places where traditional insulation would not be able to reach.

Medium-Density Spray Foam

This type is intended for interior cavity fill, continuous insulation, and unvented attic applications. It is a two-part insulation formed when an expanding gas, such as nitrogen or helium, is directed at a liquid organic substance. The gas pushes the liquids out of the pores in the insulation and forms a hard, continuous coating.

Low-Density Spray Foam

Spray foam is a material created by forcing a high-pressure stream of air and water through a container of very low-density polyethylene. This mixture is then spray-coated onto a surface to be insulated and sealed.

When the insulation is complete, the material is heated and the pressure reduced, which causes the polyethylene to fill in any gaps within the coating. This creates tighter insulation and is more resistant to thermal expansion than traditional insulation materials.

Reasons To Use Spray Foam For Energy Cost Reduction

1. Creates an Air Barrier

Your attic, crawl space, and walls are entirely sealed with foam, creating an airtight seal. As a result, during the winter and summer, you will be able to keep the warm and cold air inside, respectively.

2. Makes Moisture Barrier

The foam fills in tiny cracks in walls and ceilings and expands to a size many times larger than its original size, keeping water from entering. This will shield your house from water damage and keep the attic and crawl space from getting wet and muggy.

As a result, your dehumidifier or air conditioner won't have to work as hard to remove moisture from the air, saving you money every month on energy costs.

3. Reduce Energy Cost

If your home is well-insulated, you will lose much less warm air in the winter and much less cool air in the summer. As a result, less electricity will be used to maintain a comfortable temperature in your home by your heater and air conditioner. Your monthly energy expenses will be significantly reduced, and the savings will add up over time.


When maintaining a cozy and well-insulated home or business, consider spray foams. It can help you save money and cut down on future maintenance requirements, whether you're building a new home or remodelling an existing one.
