What Is Polyurethane Foam?

Polyurethane foam is basically obtained from a blend of fast-reacting foam producing substances that are mixed in a specific mixing spray gun at the time of utilization. The density of the foam can be even modified to satisfy different purposes and may be implemented to all substrates, which are fresh, dry, and dust-free in nature.

The reaction quickly realizes full rise & a tack-free surface and also works as a sealant. The Polyurethane foam may be protected with added coating, for example, an ignition & weather barrier.

If speaking about uses, it is used for roof’s cell insulation in industrial & residential settings, agricultural & commercial settings, cold storage rooms & marine flotation devices. Besides, let’s explore more of its benefits together!

Top 8 Benefits of Insulating Home With Polyurethane Foam

1. Better Interior Cavity Filling

Residential & commercial buildings that are insulated with Polyurethane spray foam ought to provide better protection against rust and fungus. The reason being the polymer within the insulation is inert, which means it contains no food source for unwanted mold, mildew, and bacteria.

It provides a block to external moisture, limiting mold from spreading. As walls are the chief architectural component of any building, it requires to be able to resist specific amounts of forces such as shaking during high winds.

2. Improved Roof Sealing

Spray foam insulation is beneficial in sealing roofs and other areas where condensation grows the most. As a lot of moisture can lead to mold and weaken the structural integrity of buildings, Polyurethane Foam insulation protects it well.

Since the Polyurethane insulation forms a powerful bond to the roof, it strengthens its resistance to wind & pressurization in one-go. In addition to it, it is also beneficial for decreasing sound, providing a block against road traffic, and other loud noises.

3. Superior Thermal Insulation

The heat transfer coefficient of Polyurethane Foam insulation is 0.020-0.023 W/(m2K), which is better for closed cell foam insulation. This value is far lower than the other insulation elements available on the market nowadays and best to provide additional strength. The best thing about this spray insulation is, it doesn’t get penetrated by installing fasteners that have a high thermal conductivity coefficient.

4. Block Moisture

Holes and cracks in your walls and roofs can easily allow entrance to pass air. Moisture, too, can enter these areas via unsealed holes & cracks. Polyurethane Spray Foam insulation is impermeable to water. It means not only will foam thoroughly seal and protect your walls & roofs from the leaks & moisture but also protects it from the flood if it occurs in the area.

5. Opposes Harmful Chemical Compounds

One of the other amazing benefits of Polyurethane Foam insulation is, it is resistant to the biological compounds that harm your home’s roofs & walls. It possesses better safeguarding properties than other commonly available insulation products. Therefore, when you select coatings, always verify whether it can be used together or not. It is most suitable to use materials endorsed by the manufacturer.

6. Comfort All Year Around

As open cell foam insulation keeps you fresh in the summertime and helps you stay warm in the rainy season, it offers you all year long. You never find it essential to use an extra blanket or turn your AC in peak time to keep you comfortable staying in your home.

7. Minimize Noise

Noise can disturb you all way, whether it is just a sound of fast-flowing wind or the noise of raindrops. This is why you need some coating, which can block all the sounds coming into your house. Polyurethane Foam insulation is the best solution for it. It makes an airtight seal that prevents air leaks and dramatically decreases noise transmission through walls. It will not only make your home much quieter & tranquil but also help you have a calm & comfortable sleeping.

8. Better Structural Rigidity

Polyurethane Foam adds structural rigidity to your home’s walls. National Association of Home Builders Research Center carried out an experiment & concluded that a wall having dimensions 2×4 & sprayed with Polyurethane Foam Insulation has two times better racking strength than a wall which is protected with fiberglass batt insulation. When Polyurethane Insulation sprayed inside on a plywood & roof layer, it not just blocks the wind but also boosts resistance by nearly 2.5 times that of regular nailing strength.

Final Words:

We hope, now, you have understood the benefits of using Polyurethane cell Foam insulation like how it can protect your roof and walls!

Whether you need insulation for your home’s roof, office walls, or any commercial building, this spray foam always emerges out to be the best option to opt for. It helps control air infiltration, water vapor flow, and heat flow that impact your roof’s & wall’s strength. It adds strength & rigidity to the building, protecting its moisture, cold air, and harmful chemicals.

So, if you are still thinking about why you should go for this form of insulation, then do discuss your doubts with us. We’d respond to you with the best possible.
