Pu is short for polyurethane, and Pu foam is a synthetic material formed when two chemicals, isocyanate, and polyol, are reacted. It has various uses in the industry, and it is a popular insulation material. Pu foam is good for both insulating large areas and filling in cracks and gaps. In addition, it provides consumers with durable, thermal, and water-resistant insulation.

Akfix Store offers high-quality Pu foam materials that will fit your needs best no matter what kind of insulation you prefer.

What is Pu Foam?

Pu foam stands for Polyurethane Foam. It is a kind of polymer that emerges as a result of the reaction of isocyanates and polyols. It has a porous form providing it resilience and a padding effect. Therefore, it is used in many areas of the industry, such as automotive seating, footwear, furniture, packaging, bedding, soundproofing, and insulation.

Is Pu Foam Toxic?

No, it is not. After the chemical reaction is complete, polyurethane is safe for human use when applied correctly.

Is Pu Foam Recyclable?

It is not easy to recycle PU foam due to its strong chemical bonds. However, it can be mechanically downcycled or chemically broken down into its components for reuse.

How Strong is Pu Foam?

PU foam is rigid, durable, and has high compressive strength.

What is Pu Foam Used For?

Besides various industrial uses, PU foam is ideal for insulation and gap filling due to its expansion and sealing capabilities.

Pu Foam for Attic

Perfect for sealing gaps in attic doors or around pipes to prevent airflow and reduce energy expenses.

Pu Foam for Walls

For wall insulation, seal openings around flues, recessed lights, and vents. Use Akfix Maximum for small holes and Akfix 805 Big Gap Filler for larger gaps. Finish with Akfix Thermcoat for thermal and sound insulation.

Pu Foam for Crawl Space

Ideal for crawl spaces due to water resistance and mold prevention.

Pu Foam for Metal Buildings

Use high-quality PU foam to avoid rust and consider professional installation.

Pu Foam for Basement Walls

Closed-cell PU foam acts as a vapor barrier and insulates basement walls effectively.

Pu Foam for Soundproofing

It reduces noise but doesn't completely block it.

Pu Foam for Windows

Great for sealing window gaps. Use Akfix MAXIMUM for minimal expansion and flexibility.

Pu Foam for Garage

Prevents unwanted heat transfer and protects against mold and insects.

Pu Foam for Basement

Reduces energy loss significantly. Interior application is simple and effective.

Is Pu Foam Insulation Safe?

Yes, when applied and cured properly with protective gear and ventilation. Poor installation can release toxins.

Is Pu Foam Flammable?

Yes, but fire retardants reduce its flammability.

What is the R-Value of Polyurethane Foam?

Closed-cell: 5–8 per inch; Open-cell: ~3.5 per inch.

Is Spray Foam Insulation Flammable?

Yes, it can ignite at 116°C.

Is Pu Foam Waterproof?

Closed-cell foam is waterproof; open-cell is not.

Can Spray Foam Insulation Get Wet?

Yes, but it dries out since it doesn't absorb water.

Can You Paint Pu Foam?

Yes, use latex or acrylic paint. Avoid solvent-based paints.

Worth It for Older Roof?

Yes. PU foam is durable and maintains performance up to 50 years.
