Thinking About Using Spray Foam Insulation? Read this first...

Spray foam insulation is an effective way to retain heat, coolness, and even add reinforcement. It's also an ideal solution for protection from the elements, stabilization, pest control, as well as weatherproofing. With such a wide range of applications, it is not a surprise that people have questions regarding whether to use spray foam in certain situations.

We have collected some of the most common questions regarding spray foam usage and attempted to answer them as best we could.

How many square feet can a spray foam kit cover? 

Spray-foam kits can be packaged in many sizes. They come in aerosol cans or 55-gallon drums. One cubic foot of liquid closed-cell insulation mixed properly will expand to 35 cubic yards, which is over 30 times more than its original size in liquid. Open-cell insulating foams expand up to 130 times in liquid.

Is there any waterproof spray foam? 

Some spray foams are waterproof, but others may not be. Open-cell foam is not water-resistant or waterproof. While closed-cell foam may be water-resistant but not waterproof, the highest-density foams can truly be considered waterproof.

Do you think 2 inches of spray foam is enough? 

In certain circumstances, 2 inches of spray foam will suffice. However, it is not a standard for sufficiency. It is acceptable to use closed-cell foam in walls if it is sprayed 2 to 3. It is not sufficient to spray open-cell foam into walls with only 2 inches. At least 3 inches would be required for any open-cell foam. For spraying into attics, close-cell foam should be between 4-5 inches. Open-cell foam ceiling or roof spraying should be in the 6- to 10-inch range.

What is the cost of spray-on foam insulation? 

Spray foam insulation costs are generally broken down square feet by type and thickness. Open foam spray foam is generally between $1.50 to $1.50 per sq. foot, while closed-cell insulation can cost between $2.50 and $3.

Is spray foam insulation really worth it?

Spray foam insulation can be a huge money-saver from an energy-saving perspective. Because it is dense, closed-cell insulation can be used on walls and ceilings for a wide range of purposes. These include temperature retention, waterproofing and structure stabilization and reinforcement. Open-cell spray insulation is more economical and fills in cracks and crevices quickly. But, because it is not water-resistant or vapor resistant, it is only effective when there is no possibility of moisture getting in. It serves as a strong barrier to insects and pests entering your home through its sealing capabilities.

Spray foam is used extensively in residential and industrial buildings. It's especially useful for retrofitting older homes. Spray foam can almost be applied to any substrate. Be careful not to fill in too many areas, which can lead to expansion-related damage.

Can I apply spray foam insulation on my own? 

Spray foam kits are often sold to those who want spray foam application themselves. Spray foam solutions are made up of two chemicals (isocyanate, and polyol). Both require certain temperatures in order to stay stable and usable for application. Most spray kit use an indicator that indicates when it is too cold.

There are some rules that you should follow when spraying insulation. Spraying the insulation in areas with high moisture levels or temperatures below 50 F is not recommended. Both chemicals are harmful to skin and other organs. Spray foam should be applied with gloves, goggles, breathing apparatus, and full-body covers.

How long does spray foam insulation last off gas? 

Manufacturers will send an SDS (safety information sheet) along with their products. The SDS (safety data sheet) will include information on how to maintain the spray area clean. Spray foam can release toxic fumes and gases when applied. It should be removed from the area where it was applied (except for the person performing the work) and left to dry for 24 hours to allow these toxic vapors to dissipate.

Does spray foam insulation grow mold? 

One of the main advantages of spray foam insulation's moisture resistance is also one of its primary benefits. High levels of moisture are what mold thrives in. Spray foam can be used to reduce mold growth. Spray foam insulation will prevent mold growth. Because it reduces the moisture effects in the areas it covers it is less likely to cause mold growth.

Is foam insulation safe for mice? 

Spray foam insulation is not known to attract mice for its food content. Mice will dig through things to gain entry into homes. This is especially true when it gets cold. But a tighter seal on walls and attic reduces the chance of mice entering. Spray foam may not be effective if mice are already inside the house. The theory is that the spray foam can be bitten and clawed at by the mice. However, this could cause them to abandon their cause.

Is spray foam really worth it? 

You might need to spend a few thousand dollars on the project, whether it is professional-applied or done by you. With this information, you can compare it with your energy bills, estimate any pest control or repair expenses, and then add that amount. It is possible to break down your investment by month. You'll find that you have lower energy bills and less need for many repairs related to uninsulated walls or attics. The cost of spray foam insulation will soon be offset by all other expenses. This may take several months depending on your situation. However, it is safe to say that the upfront costs will be covered soon.
