Spray Foam Insulation: Best Places to Use It in the Home

A home that’s not insulated well will most certainly make itself known. Fluctuating temperatures, moisture issues, drafts, and similar problems are often rooted in poor insulation. This is why replacement or repair of insulation in a home is vital before any bad weather comes around. A comprehensive insulation solution will benefit homes no matter what time of the year it is.

What Is Spray Foam Insulation?

Polyurethane spray foam insulation is arguably one of the best insulation products on the market. It’s an efficient block against many forms of energy, including sound, heat, and electricity. This means that if you want to install insulation in your home, you should consider using this material.

In this blog post, you will learn more about why it’s ideal to choose spray foam over other insulation materials and discover the best places in a home where you should use it.

Home Use

Spray foam insulation is incredibly versatile. This can be attributed to its unique feature: expansion. During the application process, polymer is mixed with a propellant and sprayed into an enclosed area. As the chemicals expand, the foam fills in the space. This makes it ideal for use when it comes to home settings.

During summertime, spray foam insulation helps keep the cool air in while preventing hot, humid air from getting inside. In the winter, spray foam insulation keeps out the cold drafts while keeping your home warm and cozy. Spraying polyurethane foam allows you to keep your comfort levels up and your energy bills low year-round.

Here are some of the best places for spray foam insulation in a home:

The Attic

An attic with no insulation or inadequate insulation is one of the largest sources of energy loss—especially in the winter. As hot air rises, it escapes through an attic that is not properly insulated. This increases your energy bills and damages your home by melting snow or ice on your roof because it was exposed to slightly warmer air, and this moisture then refreezes.

Summertime isn’t much better: heat rises to the upper levels of a home, making it stuffy and hot. A poorly insulated attic is a big culprit in rising interior temperatures. Spray foam insulation expands to fill gaps, cracks, and crevasses to solve this problem, and it works particularly well in the attic.

Make sure to keep a close eye on the ceiling and floor joists as your attic insulation is being inspected. Sealing off the living space below by insulating between and over floor joists is a crucial step when finishing your attic. Walls with attic space behind them, known as knee walls, should also be targeted.

The Walls

Warm air inside your home can escape through wall cracks, making it feel colder in the winter. At the same time, warm air outside can push its way into your house through cracks in the walls, making it uncomfortably hot in the summer. 

Interior wall insulation will require working around ductwork, wires, or pipes; the ductwork needs particular attention. This is because cold or warm air generally tends to enter homes through ducts.

Spray foam can fill any nooks and crannies with no problem.


Insulation is vital for any home. The ideal method to take on is spray foam insulation. It offers flexibility and guarantees full coverage. The best places for it in a home include the walls and the attic.
