Perks and Benefits of Spray Foam Insulation

If you need new or replacement insulation, consider spray foam insulation for your attic and crawl space. Spray foam insulation is highly durable and energy efficient, both attributes that define the best attic and crawl space insulation. It is an excellent alternative to rock wool, fiberglass, and cellulose insulation products. Having spray foam insulation in your home or business can save you money and help you to have healthy air in your home.

Impact of Old Insulation

Poor-quality insulation can lead to unhealthy indoor air and allergic reactions for people with allergies or asthma. Fiberglass insulation, developed in the 1930s, is a common insulation in homes and businesses. Unfortunately, fiberglass insulation is limited in coverage. Coverage issues result in higher energy bills due to the gaps that allow the flow of air in or out. Because of these gaps, your air conditioner is forced to frequently go on and off, increasing your energy bill in the process.

Fiberglass insulation also collects moisture that doesn’t dry out. Eventually, damp insulation in a cool, dark space leads to mildew and moisture growth, negatively impacting air quality in your home and triggering allergies or asthmatic episodes.

 

Types of Spray Foam Insulation

There are two types of spray foam insulation: open-cell and closed-cell insulation. We’ll examine the features and benefits of insulation on both fronts.

Open-cell insulation features include:

  • ½-pound density per cubic foot
  • Dampens sound
  • Flexible with seasons
  • Less expensive than closed-cell insulation
  • R-value of 3.7 per inch

Closed-cell insulation features include:

  • 2-pound density per cubic foot
  • Acts as a moisture barrier
  • Reinforces structure
  • More expensive than open-cell insulation
  • R-value of 6 per inch

 

What’s the Best Type to Use?

Using closed-cell insulation on the exterior of a home is best, while open-cell insulation works better for the interior of a home. Installers apply these two types of spray foam insulation slightly differently. Closed-cell insulation uses chemicals and water to spray, while open-cell insulation only uses water. Closed-cell tends to dry stiff while open-cell is spongy.

Benefits of Spray Foam Insulation

Discover some of the many advantages of spray foam insulation.

1. An Excellent Insulator

Spray foam insulation is a much better alternative to traditional forms of insulation for your attic and crawl space. It expands and tightly seals spaces that were previously left exposed to the elements. The resistance value (R-value) – meaning its ability to form an airtight seal – ranks as the highest available on the insulation market. Cellulose has a value of just over 3, and rock wool and fiberglass less than 3.

2. Significant Energy Savings

One of the most important benefits of spray foam insulation to consumers is the spray foam’s ability to save on heating and cooling costs. Because spray foam’s properties provide such great insulation coverage, the savings are significant. Homeowners may save up to 50 percent on energy costs, which is much more than traditional insulation.

3. An Airtight Seal

Unlike fiberglass insulation, one of the greatest advantages of spray foam insulation is that it completely seals the spaces. Holes, cracks, beams, corners and crevices – all have an airtight seal after application. No more air leaks occur when installers properly place this type of insulation.

4. Prevents Moisture and Mold

Moisture can seep into attic and crawl spaces through holes and cracks. When sealed with spray foam insulation, these spaces become impermeable to water. This form of insulation completely seals and protects your attic or crawl space! This reduction in moisture significantly reduces the risk of mold in your attic or basement.

5. It Lasts for Years

You may need to replace or fill traditional insulation multiple times over the year you are in the home. Spray foam insulation lasts indefinitely! In contrast with other forms of insulation, it has the ability to last for long periods of time.

6. Reduces Noise

Spray foam’s airtight seal and thickness can significantly reduce noise in your home. If noise pollution is an issue for you, spray foam is an ideal solution to reduce or eliminate noise.

7. Environmentally Friendly

Spray foam insulation is eco-friendly in that it reduces energy consumption, protects against mold growth, and lasts indefinitely.
