Why Spray Polyurethane Foam is the Architect’s Best Friend

In the past, one thinks of polyurethane only as the material used to stuff your mattresses and sofas to make them quite comfortable for you and your family. These days, polyurethane foam is not limited to that sole purpose. It has evolved to become one of the most versatile materials on the planet. There are numerous uses and densities for polyurethane for it, with low density flexible foam is, for example, being used for your beddings and seating while a light covering of polyurethane finish over a polyester weave creates a water and windproof polyurethane laminate which is used in outerwear and shower curtains.

Did you know that polyurethane is also a recommended material for architects? It also comes in a form called spray polyurethane foam and it is absolutely one of the materials an architect cannot do without.

There are two types of spray polyurethane insulation. The architect needs to pick the correct one in order to deliver the best possible service for the client.


Open Cell Polyurethane Foam Spray

This type of foam spray uses fewer chemicals as compared closed cell spray polyurethane foam which results to it being less expensive than the other type. It is best for indoor use and has a spongy texture to it.

Closed Cell Polyurethane Foam Spray

Considered to be the denser of the two types, closed cell is the one more commonly seen in homes. It is more resistant to water and also has better insulation. Closed cell spray polyurethane foam can be used not only indoors but outdoors as well.

What’s so special about Polyurethane Foam?

Cost Efficient

One of the chief problems an architect’s client will encounter is costs. After having their dream home built, they will want to tighten the built a bit as having a home constructed is not something to be considered cheap or if it were to be termed nicely, inexpensive. By having spray polyurethane foam for insulation, you will not be only saving your clients money with construction material but in the long term as well. They will be able to save big time when it comes to energy costs and utility bills. Now isn’t that nice?

Health Is Wealth

Is the client health conscious? Then spray polyurethane foam is the way to go. Did you know that it is actually anti mold and anti-mildew? It prevents the formation of moisture, which is what causes the mold to grow. Said mold can lead to severe health problems which may land the client in the hospital. If you choose spray polyurethane foam, you can be sure harmful mold will not grow in the places you’ve used them on.


Yup, it is waterproof which makes it great material to be used for your roof. If the top layer has been damaged by different factors, you can be assured that no water will leak through as the underlying layer will protect the roof from dripping.

Adds Structural Integrity

This foam isn’t just for insulation but for structural integrity as well. If we are to become specific, it is closed cell spray polyurethane foam that provides structural integrity. The outer wall is reinforced and made more rigid by the foam. Walls with spray polyurethane are proven to be 300% stronger than those without.


Of course, the primary reason why you should choose spray polyurethane foam is for its insulation properties. It is more efficient than your fiberglass or cellulose insulation. In addition to this, it really sticks to the wood substrate and sheathing, ensuring that every single crack and crevice is covered. If you are to refer to its R-value or the thermal resistance against heat, it has the highest R-vale rating compared to fiberglass and cellulose at R-5 to R-6.


Well architects, what are you waiting for? Recommend spray polyurethane foam to your clients the next time you see them and for sure they will thank you for this wonderful suggestion.
