Why Foam Insulation for Walls and Doors Might Be Best for Your Remodel

As you remodel your home, you should consider replacing your old fiberglass insulation with foam. Many ask why foam insulation for walls would be best to use. The advantages of using it make it a top choice for any modern home.

Why is insulation used? 

Most people know that insulation is important for keeping their homes warm in the winter and cool in the summer. But why is insulation necessary? Basically, insulation works by trapping air. This way, heat is not able to travel through the walls of your home as easily, making it easier to maintain a comfortable temperature inside. In the winter, insulation prevents heat from escaping, helping to keep your home warm. In the summer, it prevents heat from entering, helping to keep your home cool. Additionally, insulation can also help to reduce noise pollution and minimize energy costs. So if you’re looking for a way to make your home more comfortable and energy-efficient, insulation is definitely a good option.

What are the different types of insulation for a home?

When it comes to insulation, there are several different options to choose from. The most common type of insulation is fiberglass, which is made from small glass fibers that are spun into a mat. Another popular option is cellulose, which is made from recycled newspapers or other plant-based materials. There are also a number of foam-based insulation options, such as polyurethane and polystyrene. Each type of insulation has its own advantages and disadvantages, so it’s important to do some research to figure out which option is best for your home. With a little effort, you can find the perfect insulation for your needs.

Closed-Cell Foam Insulation Has a Superior R-Value

R-value measures how well different types of insulation perform, and closed-cell foam tops the list. The higher the R-value, the better the insulating qualities. Fiberglass insulation has an R-value of 3.2 per inch compared to 6.2 per inch for closed-cell foam insulation.

Seals Cracks and Gaps

If you’ve had a problem with rodents or insects getting inside your home through gaps in the walls around pipes or wiring, spray foam insulation could stop that. This is because it expands to seal all gaps and cracks.

In the same way, spray foam insulation also seals out drafts. This is especially true for old, wood frame homes. The ability of spray foam insulation to seal cracks also means that it can seal water leaks. You can also use it when installing a front door or placing a new bay window to help prevent any drafts from being able to enter the home. When sprayed around pipes, it also prevents condensation. This means that insulating your walls with it can help to prevent mold growth.


Can Strengthen Walls

Since high-density closed-cell spray foam adheres to the walls, drying to form a rigid barrier, it also adds strength to exterior wooden, vinyl, or metal walls. This is especially helpful if you are restoring a historic home that needs some reinforcement.

Also, high-density closed-cell spray foam insulation will reduce or eliminate creaking, shaking, and vibrating during windstorms. If your home is made of anything other than brick, it can add rigidity to your walls.



No matter where you live, you’ll be able to find a contractor offering spray foam insulation services. This type of insulation has quickly grown in popularity over the years, and most building contractors now offer spray foam insulation services.

Spraying it requires specialized equipment and know-how, so it’s not something the typical homeowner can do themselves. It not only involves mixing chemicals and specialized equipment, but also you’ll need to wear protective clothing and gear. Because of this, it makes sense to hire professionals like Insulation Brothers Ltd to help you do the job properly and safely.

The process of spraying it is relatively quick, but you’ll need to stay out of the area for at least 24 hours. This will give the foam time to cure and for any fumes to dissipate. Once cured, drywall can be hung over the foam.

If you are remodelling your home, consider using it. It not only has superior insulating qualities, but can also strengthen weak walls and seal out moisture, drafts, and pests.
