The best insulation materials to support your HVAC System

When the weather gets cold, many homeowners rush to their HVAC system to provide much-needed warmth. Indeed, you need a properly functioning heating system to provide warm air at the required temperature throughout the home.

But did you know that for your heating to work correctly, you need proper insulation? Your walls, roof and floors need to be insulated with a material that prevents air from leaking in and out of the property. Regardless of how efficient your HAVC system is, you may not enjoy warmth and comfort in the home if you have poor insulation. Here are some of the most reliable insulating materials that will prevent air from leaking.


Polyutherane is a useful insulating material that can be easily applied to multiple areas of the home. It exists as foam, and the foam is sprayed onto walls, roofs and floors to prevent air from leaking.

The lightweight foam is convenient to use in many different homes. Because it has a low density, it can be applied to small corners and difficult to reach places where leaking air gets in/out. Polyutherane foam is also a fire-resistant material, and it provides further protection for your property.


Fibreglass is perhaps the most common insulating material currently in the market. Its structure consists of finely woven strands of glass embedded in an insulating material. The end result is a cotton or mattress-like material that is stuffed between the layers of walls, roofs and floors.

Part of the popularity of fiberglass arises from its cost-effective nature. You can insulate large portions of your home at a reduced cost with fiberglass, which is also non-flammable.


Cellulose is another effective insulating material for the home. It is made from recycled cardboard, and it is an excellent choice for preventing leaking air and fire damage.

Cellulose fibres can be stuffed inside walls and roof layers to insulate the home. This material should be regularly inspected to ensure that fibres are not being released into the air. Indeed, damaged cellulose fibres can cause irritation or spark allergic reactions.

Plastic film

A less common, yet effective insulating material is plastic film. Also existing as polyethylene bubbles, this material operates by reflecting items away from the surface. You can use it to frame your walls and floors so that heat doesn't flow away from the home when your HVAC system is on.

Not only does proper insulation make your heating system more effective, but it also reduces energy consumption in the home.
