The Science Behind Spray Foam Insulation: How It Works
May 28, 2021

What’s the king of insulations that fills every nook and cranny? Spray foam. Spray foam insulation plays a critical role in building science, as its functions consider the whole-building approach. Whether used in commercial or residential buildings, spray foam is valuable insulation that safeguards against air leakage as a thermal and sound barrier. Spray foam insulation effectively supports the performance of supplementary building materials and construction systems of a home or property.

Surely you have heard about spray foam before, but you may not be familiar with its inner processes. Are you curious about how this insulation does the trick so well? Let’s take a closer look at the science behind spray foam insulation: how it works.

Signed, Sealed, and Delivered: A Proven Tool

The energy performance and comfort level of a building revolve around its insulation. Air leakage is a major problem for homeowners with a strong impact on heating and cooling bills. Of the various insulation options available today, spray foam is a green building material that proves a better barrier for cost savings and comfort. New and existing homes alike benefit from its solutions.

The development of spray foam consists of two main composite materials: polyurethane and isocyanate. The innovative mixture of these materials creates a chemical reaction that expands to fill a space, then efficiently hardens. The application of spray foam to an open cavity works wonders to form a barrier. During installation, spray foam expands up to 100 times to fill a structure's every nook and cranny. Since spray foam is pliable and light, the insulation can move with a structure without cracking or pulling away.

Spray Foam: The Making of Successful Seals

The science behind spray foam insulation and how it works is relatively simple. As mentioned above, contractors mix two components from diverse containers to create spray foam. Conventionally, the “A” side of the system contains the main liquids, while the “B” side is a blend of catalysts that creates a reaction as soon as the chemicals mix. This mixing process happens on-site using special equipment for the task at hand.

With professional rigs and proper tech, contractors can mix the foam perfectly and maintain the correct temperature. A suitable dispensing applicator gun offers flow control for precise installation. Keep in mind that certain manufacturers have their own spray foam blend, so be sure to ask your contractors about specific products and materials before installation.
