Spray foam insulation, as the name suggests, is a spray-applied insulating product. Also referred to as spray polyurethane foam (SPF), the unique material expands upon contact to tightly seal gaps and crevices.
Due to its unique properties, spray foam insulation is highly effective. But is it the right choice for your home? The following guide may help you decide.
Open Cell Spray Polyurethane Foam
Open cell foam is the least expensive type of spray polyurethane insulation, as it as low-density material. It also has the lowest R-value, which is a measurement of how well a product prevents heat transfer and air escape.
However, open cell SPF insulation can be a great sound dampener, and contractors often use it for interior walls and unvented attic spaces. For these applications, open cell foam can be a practical choice.
Closed Cell Spray Polyurethane Foam
Medium-density and high-density closed cell foam are available, and each is typically used for different insulating purposes.
For continuous insulation and wall cavity fill, medium-density SPF insulation works well. High-density SPF, which has the highest R-value and cost of the three options, is typically reserved for exterior and roofing applications. This is because high-density polyurethane foam acts as a structural reinforcement, and these areas can benefit from both insulation and strength.
Pros & Cons of Spray Foam Insulation
Spray polyurethane foam offers several clear advantages. Reasons to choose SPF insulation include:
- Better insulation – SPF gets into all of the nooks and crannies, filling them so that no air can escape.
- Zero drafts – After applying spray foam, drafty areas and chilly spots are things of the past.
- Pest protection – SPF insulation provides a barrier to insects, preventing them from infiltrating your home.
- Moisture block – As SPF is impermeable to water, the material can protect your home from airborne moisture and water leaks.
- Energy savings – Because SPF is so effective at insulating, choosing it can result in much lower heating and cooling costs.
- Long lifespan – SPF lasts for many, many years. According to insulation experts, it has an indefinite lifespan.
Like any other type of insulation, spray foam does have a few drawbacks. It costs more than most other options, and the application process isn’t exactly neat. Without proper care, the polyurethane foam can accidentally go outside the intended target area. And if too much SPF is applied, thinner walls could buckle as the material expands.
Fortunately, with the right insulation contractor, the risks of applying SPF are minimized – and so is the cost. In northern Utah, southern Idaho and Wyoming, GreenHome Specialties is the contractor to trust.
