It has excellent thermal properties, with an R-value of 1.1K·m2/W per 25mm – making it an ideal choice for residential or commercial insulation, as it provides both insulation and structural integrity. Not all spray PU foams offer these benefits – that’s why we take pride in using only the best.
If you run a commercial facility and are looking for a better insulation solution, closed-cell spray foam insulation is the way to go. Especially handy in cold storage facilities, it provides a vapour barrier that prevents condensation. By ensuring that the facility’s temperature and moisture levels remain stable, the foam can improve your facility’s energy efficiency and enhance its overall performance.
Open-cell Foams
Our open-cell spray foam insulation is ideal for noise insulation or cavity filling. It has a lower density than closed-cell foam, which means it requires a thicker application to achieve the same “R-Value.” However, it is a cost-effective insulation solution “R-Value.” It offers an R-value of 0.78K·m2/W per 25mm and better noise insulation properties than closed-cell foam. It rises to 80-120x its liquid volume, making it ideal for sealing cracks and crevices and providing excellent insulation coverage. However, in damp areas, it may allow water vapour to migrate through it over time.

More on Polyurethane
Polyurethane foam, sometimes shortened to PU foam, is a versatile material that has found its way into many industries due to its unique properties. There’s a reason we rate it so highly here at NZAS. From insulation to cushioning, polyurethane closed-cell foam and open-cell foam products have become our go-to material for a variety of applications.
What is Polyurethane Foam?
The resulting chemical reaction from combining polyol and isocyanate produces polyurethane foam, a special type of foam that can mould into all sorts of shapes. The foam can be produced in a wide range of densities – from low-density foam used for cushioning and packaging to high-density foam used for insulation and structural support.
Benefits of Polyurethane Foam
Foam made of polyurethane offers several benefits that make it a popular choice in many industries. First and foremost, it is an excellent insulator. When the foam has a closed-cell structure, it is an incredibly effective barrier against heat transfer, which makes it an ideal product for insulation applications.
This foam is also incredibly durable: it’s able to withstand a great deal of stress and pressure without degrading, so it’s ideal for use in products subjected to a lot of wear and tear.
Uses of Polyurethane Foam
While we make the most of its insulation properties at NZAS, polyurethane foam has found its way into many industries – it is a foam that’s useful for so much more:
1. Insulation – Polyurethane foam is an excellent insulator, ideal for insulating buildings and homes. We spray the foam into walls, ceilings, and floors to create a seamless barrier against heat transfer.
2. Cushioning – Low-density polyurethane foam is often used for cushioning in packaging and furniture. The foam is so easily moulded, it fits a variety of shapes and sizes – ideal for protecting fragile items during shipping.
3. Automotive – Polyurethane foam is used in the automotive industry for soundproofing, insulation, and cushioning. You’ll often find the foam in car seats, headrests, and door panels.
4. Construction – High-density polyurethane foam is often used in construction for structural support. The foam can be poured into cavities to create a solid foundation that is resistant to settling and shifting.
5. Footwear – Polyurethane foam is often used in the manufacturing of athletic shoes, as the foam is lightweight and provides excellent cushioning, which makes it an ideal material for running shoes and other athletic footwear.
Closed-Cell and Open-Cell Polyurethane Insulation Products
Closed-cell foam and open-cell foam are two types of polyurethane insulation products that offer different properties and advantages.
Closed-cell polyurethane foam is a denser and more rigid foam that has a higher R-value (a measure of thermal resistance) than open-cell foam. The cells of the foam are tightly packed together and sealed – as a result, the foam becomes impermeable to air and moisture. This makes closed-cell foam products an effective air and moisture barrier, which is why it is often used in applications where moisture resistance is critical, such as in basements, roofs, and crawl spaces. Additionally, closed-cell foam is also more resistant to damage from impact or compression than open-cell foam.
Open-cell polyurethane foam, on the other hand, is a softer and more flexible foam that has a lower R-value than closed-cell foam. The cells of the foam are not tightly packed together, which allows air and moisture to pass through it more easily. This makes open-cell foam effective at sound dampening – a good option for use in interior walls or ceilings where noise reduction is desired. It is also less expensive than closed-cell foam and easier to install.
When choosing between closed-cell foam and open-cell foam for insulation, it is important to consider the specific needs and requirements of your project. If moisture resistance and high R-value are a top priority, the closed-cell foam may be the best choice. However, if you are looking for an insulation material that can provide sound reduction or a more cost-effective option, the open-cell foam may be a better fit.
