TYPES OF SPRAY FOAM

Open-Cell Spray Foam

Open-cell spray foam is a type of insulation that expands after installation to create small, open cells within the foam. This makes it softer and more flexible compared to closed-cell foam. Its structure allows it to fill nooks and crannies in walls, providing an effective air sealing property.

Benefits

When considering spray foam insulation cost, Open Cell Spray Foam emerges as the less expensive choice. Additionally, open-cell spray foam has excellent sound-damping properties. Despite having a lower R-value (about 3.5 per inch), it is an effective insulation material and allows for bi-directional drying, preventing moisture accumulation within walls.

Applications

Open-cell spray foam is ideally used in interior walls and ceilings where soundproofing is desired. Its ability to conform to irregular shapes makes it an excellent choice for intricate framing details.

TYPES OF SPRAY FOAM

Closed-Cell Spray Foam

Closed-cell spray foam is a high-density insulation material with tiny, compact cells. This gives it a rigid structure, enabling it to provide added strength to the wall assembly, besides offering thermal insulation.

Benefits

Closed-cell spray foam offers a higher R-value (about 6-7 per inch), making it a superior insulator. Its dense structure adds rigidity to walls, enhancing the overall structural integrity. Moreover, it is highly resistant to water and air infiltration, contributing to a healthier and more energy-efficient indoor environment.

Applications

Closed-cell spray foam is best suited for exterior walls, roofs, and areas that require superior insulation and water resistance. Its strength-enhancing properties make it an excellent choice for buildings in regions prone to severe weather conditions.

Benefits of Spray Foam Insulation

A Detailed Look at the Total Cost of Spray Foam Insulation

Lasting efficiency: superior insulation that enhances energy savings and structural strength.

Superior Insulating Properties

Spray foam insulation, especially closed-cell foam, boasts a high R-Value, making it a powerful insulator. It expands to fill gaps and cracks, providing a seamless insulation barrier. This ability to conform to irregular shapes allows it to effectively seal off air and moisture infiltration, ensuring a cozy and comfortable indoor environment.

Energy Efficiency

Spray foam insulation can significantly reduce your energy consumption, leading to substantial savings on utility bills. By providing an air-tight seal, it helps maintain a consistent temperature indoors, reducing the strain on your HVAC system. This energy efficiency is not just good for your wallet, but it also contributes to a sustainable and eco-friendly lifestyle.

Enhanced Structural Integrity

Closed-cell spray foam insulation does more than just insulate. Its dense and rigid structure adds strength to your walls, roofs, and floors, enhancing the overall structural integrity of your building. This added strength can be especially beneficial in areas prone to extreme weather conditions.

Long Lifespan

Spray foam insulation is designed to last. It maintains its performance over time, often outlasting the lifespan of the building itself. With spray foam insulation, you’re investing in a long-term solution that won’t sag or settle over time, providing consistent performance year after year.

Spray Foam Applications

FAQ’s about Polyurethane Spray Foam

What is spray foam insulation?

Spray foam insulation is a type of insulation that is sprayed in place and expands to fill cavities, cracks, and gaps, providing a superior air and moisture barrier.

What is the chemical structure of polyurethane foam?

The chemical structure of polyurethane foam is based on the condensation reaction of an isocyanate and a hydroxyl-containing compound, usually a polyol. This reaction creates cross-linked molecules that form a flexible and durable foam when combined with a blowing agent.

How is polyurethane foam produced?

Polyurethane foam is produced through either a liquid injection foam or slabstock foam process, depending on the desired properties and intended use of the final product. Each method has its own advantages and disadvantages, so finding the right method for a specific application is key to achieving optimal results.

How strong is polyurethane foam?

The strength of polyurethane foam depends on various factors including density and formulation, but generally speaking it is known to be very resilient and durable material.

What is polyurethane used for?

Polyurethane foam can be used for applications ranging from cushioning, soundproofing, impact protection, energy absorption, thermal insulation, packaging materials and more.

Is polyurethane foam environmentally friendly?

Most types of polyurethanes are non-toxic and considered environmentally friendly compared to other materials such as oil-based plastics or foams made with CFCs (chlorofluorocarbons). Ecomate is a blowing agent from FSI that is EPA SNAP certified to replace blowing agents with harmful chemicals.

Are there any health risks associated with polyurethane foam?

Generally speaking there are no health risks associated with using polyurethane foams but some individuals may be sensitive to certain components such as diisocyanates which may cause irritation when handled without proper protective equipment.

What are the 2 main types of polyurethane foam?

Flexible foam, which is used mainly in cushioning and upholstery, and rigid foam, which is used mainly in insulation and structural support.

What is a polyurethane systems house?

Polyurethane systems houses provide comprehensive solutions for producing polyurethane chemical systems, utilizing state-of-the-art production processes and customized options to ensure projects are executed with precision and accuracy.

Will spray foam stop water?

Yes, spray foam insulation can stop water and prevent outside moisture from entering your home. Spray foam is water-resistant and can be completely waterproof depending on its type. The higher density of closed-cell foam makes it a great vapor barrier and can reduce moisture and mold issues in attics and crawl spaces.

Spray foam can also seal off small gaps where moisture can enter your home by forming an airtight seal at the base of the wall or ceiling.

Why is spray foam insulation so expensive?

Spray foam is expensive because of the materials, equipment, and training required to install it. It’s not as simple as picking up some insulation at the hardware store, and requires hiring a professional team to bring their spray foam machine. Spray foam can also cost more than other types of insulation, such as fiberglass, because it takes more time to install.

Spray foam insulation can cost up to $1 per square foot. While it costs more up-front than traditional insulation, it can lead to big savings on heating and cooling costs over time. Its highly effective heat retention means you don’t need to use as much energy to heat your home, which could save you up to 50% on your energy bills.
