The Technology Behind Spray Foam Insulation

The insulation of any building structure is of critical importance. It not only reduce the energy costs involved in warming and cooling the building, but it also helps to reduce the carbon footprint of doing so. With this in mind, the best insulation method is one with the highest R-value (the value indicative of insulation efficiency) is usually the to-go-to insulation method.

One of the most efficient insulation solutions is the spray foam insulation. As an insulation method, spray foam is tremendously versatile and fast to implement all around your house. Its versatility makes it very easy to use it in different places such as the attic and the basement, without leaving any part uninsulated. Thus, it is popularity.

So, what technology drives this insulation method, you may ask. Herein we will look at the various bits that make spray foam insulation possible.

Understanding Spray Foam Technology

The basis of spray foam technology emanates from the development of the polyurethane foam right before the world war by Otto Bayer in Germany. Soon the World War II was raging, and the majority of this chemical was used in the manufacture of weapons system on the both side of the Atlantic. Image result for spray foam insulation

The second bit of innovation that improved the use of spray foam as an insulation material is the Blendometer, in the 1950s. The Blendometer allowed the mixture of the constituent chemicals used to make the spray foam. However, this device was incredibly laborious, and as such, only a few companies offered the use of polyurethane as a property insulation solution.

However, the energy crisis during the 1970s increased the need to have in place effective insulation. In this regard, the crisis spurred development of mixing and spraying technologies. This lead to the improvement of the mixing technology, by introducing the spray nozzle.

The spray nozzle was the last piece of the puzzle that led to the proliferation of the spray foam insulation. The nozzle replaced the laborious mixture and paved the way for a more convenient and easy method of spraying the foam. The spray nozzle allows the constituents of the polyurethane to mix right before ejection. This ensures that the polyol resin mixes with the isocyanate – the substance responsible for the expansion and formation of foam – stay separate until the last possible moment. Overall, the nozzle has improved the application of the spray foam, thereby improving its popularity.

The Benefits Of Using This Technology

One obvious benefit is the saving made in energy operating costs, of between 30% and 50% as it has the highest performance of any insulation solution. Additionally, it also offers stable insulation performance throughout time. This is no marginal saving such saving can amount to hundreds or even thousands of dollar annually. The spray foam also improves overall noise insulation, reducing noise transmission into your house. Winnipeg Spray foam insulation also acts as a deterrent for mold, especially in your basement. The surface of the foam is not conducive enough for mold growth. Finally, the foam also adds structural stability.
