What You Need to Know About Spray Foam Insulation

An insulated home is a happy home. Spray foam insulation delivers lower heating costs, no dampness, and a quiet environment to your indoor spaces. The expanding nature of foam insulation ensures that all nooks and crannies are filled, and the outside is firmly left outside without seeping into your inside.

What Is Spray Foam Insulation?

Foam insulation is a polyurethane foam that can be applied to surfaces to seal all possible air leaks in a building structure. You can apply the foam around all attic vents, windows, door frames, roof joints, etc., to keep the conditioned air inside the house. 

The foam canisters contain two types of liquid that combine as they come out of the nozzle to form a foamy substance that expands to fill the space where it is applied. The foam hardens and provides a durable seal. It is a long-lasting type of insulation that will not need to be replaced during the lifespan of your house. 

Can You Spray Foam on the Underside of the Roof?

Foam insulation products can be sprayed on the underside of the roof sheeting to provide insulated attic space. Since most heat in a home is lost through the attic space, it makes sense to apply insulating products that prevent heat loss and improve the home’s energy efficiency. 

Using spray foam on the underside of a complex roof construction effectively seals the assembly and provides thermal and vapor control layers.

Can You Insulate Your Home With Spray Foam by Yourself?

The answer to this question is yes and no. Although an experienced home DIY enthusiast can attempt to fill in small areas around doors and windows as a DIY project, it is not advisable to fill in large spaces like the underside of your roof or insulate your walls by yourself. 

Although the do-it-yourself kits available in hardware stores make it seem easy to apply spray foam insulation, getting professional advice with proper product selection and application can be invaluable to the success of your project. 

Can You Install Spray Foam Into Existing Dry Wall Construction?

The answer is yes. You can install spray foam insulation into existing drywall construction. However, you need to remove the drywall before installing the foam. Without removing the drywall, you run the risk of overfilling the cavity, and as the foam expands, it will exert pressure on the plasterboard, which may cause cracks in the wall.

It is a messy and time-consuming job, but hiring experienced technicians will save you labor and provide guidance on exactly which parts of the wall need to be removed to complete the job. You will be able to enjoy the full benefits of an insulated home without the hassle and extra costs of replacing damaged drywall if your attempt goes sideways.
