Spray Foam Insulation

Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making the building more energy-efficient and comfortable. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution for reducing unwanted air infiltration through cracks, seams, and joints.

Spray foam forms when the distinct liquid components react with each other and expand rapidly to create a foamy texture. It acts as an effective insulator for tight spaces in wall cavities, roofs, or ceilings, sealing gaps and creating moisture, air, and vapor barriers.

Spray Foam Insulation for Your Place

Spray foam can be a great investment in your home. Spray foam is a powerful insulation material with a high R-value and air barrier properties that give it the unique ability to fill gaps and holes that could be difficult to seal. Spray foam can help lower energy bills by reducing heat loss or gain, eliminating air leaks, and improving your home's energy efficiency. It won't compress, sag, or settle over time.

Thanks to its thickness, spray foam provides optimal thermal resistance, helping to maintain a comfortable indoor temperature. By installing spray foam insulation, many homeowners improve the energy efficiency of their homes and lessen air leakage.

Where is Spray Foam Insulation Used?

Spray foam insulation seals walls, floors, and ceiling cavities against air movement. This includes spaces around electrical outlets and light fixtures, as well as where walls meet windows and doors. Spray foam can be sprayed into an open cavity, like in new construction, attics, crawl spaces, and rim joists. It can also be used in existing homes, commercial buildings, and pole barns. As long as the cavities are open and there is access, then the spray foam can be applied.

Spray foam is capable of creating a seamless, airtight barrier that isolates the construction from pesky sounds and water infiltration, fosters the upkeep of the optimum temperature, positively affects air quality inside the building, and ameliorates the overall durability of the construction. 

Professional contractors use both interior and exterior walls to effectively insulate every inch of the surface to ensure comprehensive protection and energy efficiency.

Spray Foam Advantages & Benefits

  • Lower energy cost
  • Stops drafts allergens and condensation
  • Quieter indoor environment
  • Adds structural strength
  • Seals cracks and voids

Lower Energy Costs

Considering how to improve your energy savings? Then, apply additional layers of spray foam insulation to the cracks in your new construction. Professional spray foam insulation will minimize the transfer of heat, diminish air infiltration, keep the optimal temperature, and thereby reduce your heating and cooling costs.

Stops Drafts, Allergens, and Condensation

The spray foam products fill wall cavities and seal the gaps between windows and walls, doors, and walls, preventing cold winds from entering the house. The complete coverage also allows the blocking of entry points for allergens such as pollen, dust particles, and other airborne particles deteriorating human health. Moreover, by creating a solid barrier, it diminishes the likelihood of moisture accumulation.

Does Not Settle or Shrink

The unique chemicals of the spray foam expand, insulate the cavities, and fix them in this form without losing them over time. The foam is adhesive, and once applied, it doesn't come off the surface unless you decide to remove it.

Quieter Indoor Environment

Insulating your residential area or an office building ensures peace and quiet since, among other things, the material possesses sound-deadening properties. It dampens sound waves, preventing outdoor noise from traveling through the building and creating an atmosphere of acoustic comfort.

Adds Structural Strength

The bond formed by spray foam insulation attached to different surfaces strengthens the existing structure. Filling the seams resists possible roof or wall movement, ensuring that everything sits in place.

Seals, Cracks, and Voids

The spray foam is very effective when confronting uneven surfaces, irregular shapes, and hard-to-reach spaces. It expands upon application, permeating into every inch of the cavity, no matter size or form, and ensuring seamless filling. This type of insulation is very resilient and enduring in comparison with other sealants.

Spray Foam: How to Choose

Spray foam material is a compound blend of chemicals that puffs up upon exposure to air. However, the foam differs in density, R-values, and other types of foam parameters.

Let's take a look at the popular sealant options:

Low-density spray foam insulation

Low-density spray foam has lower R-values and is soft, flexible, and more permeable. Its advantages encompass continuous insulation for preventing air and noise. Also, it is convenient for places where controlled air flow is beneficial. For instance, in climates with altering moisture levels. Unlike two others, this sealant option belongs to the open-cell foam insulation type, and its main use is for unvented attics and interior walls.

Medium-density spray foam insulation

With its higher R-value, this spray foam insulation boasts exceptional air, vapor barrier, and water barrier properties. The effect of heavy rains on it is less than with low-density spray foam, so it's more suitable for use in exterior and roofing applications. More so, it offers significant tensile and bond potency, which improves its ability to seal openings, increasing structural robustness.

High-density spray foam insulation

The thickness of this spray foam insulation determines the highest R-value it provides. This way, it appears to be the most effective in reducing the transfer of heat and cool; its characteristics allow additional support in holding the building's internal elements, and its monolithic nature contributes to establishing hermetic closures and diminishing air and water penetration.

There are also open-cell and closed-cell insulation types, each spray foam type characterized by distinct properties and applications. Open-cell foam insulation is a soft and less dense foam suitable for hardly accessible spaces due to its expansion characteristics. Open-cell insulation is perfect for soundproofing, but it also allows moisture to pass through.

As for closed-cell spray foam, it's denser and offers a robust barrier, preventing moisture from penetrating isolated spaces. The closed-cell foam acts as an effective vapor barrier, providing an extra means of moisture resistance. It's more suitable for basements and bathrooms since it won't develop mold. 

However, if you live in coastal areas where the ground level is prone to subside, this sealant may not be the best option as it lacks flexibility.

Frequently Asked Questions — FAQ

Is there a downside to spray foam insulation?

Spray foam is a good fill for hard-to-reach places, but there may be challenges connected to its use. Firstly, if you install it improperly, it may result in a reduction of its properties. If the temperature fluctuates during the foam application, it may lead to overexpansion or contraction, as a result of which some gaps will remain unsealed. Also, some foam types consist of chemicals with potentially harmful effects on the body, so it's very important to choose a trusted supplier.

Can you do spray foam insulation yourself?

In fact, you can buy a spray gun and foam, which are usually part of standard DIY kits. However, for safe foam insulation, you'll also need such things as protective gear and a polyethylene sheet to cover your items. All of these cost a decent amount of money, but they do not guarantee a satisfying result. Thus, we recommend reaching out to professionals to prevent such potential issues as mold and poor insulation performance caused by inadequate application.

Where should you not use spray foam?

Spray foam may not be as good for areas inclined to shifting. If your house is situated in a region with clay soil or on a coastal line where the ground level changes over time, the foam may crack with the amount of movement. Also, certain varieties of spray foam insulation shouldn't be exposed to direct sunlight, as their properties are reduced upon contact with UV rays. Lastly, we don't advise using foam for areas that require frequent maintenance, for example, areas near wires or pipes that deter easy access to them.
