Spray foam insulation is a type of insulation that is applied to surfaces in a liquid form and expands into a foam-like substance. It is made by combining two chemicals, polyol resin and isocyanate, which react when mixed. This reaction causes the mixture to expand and harden into foam insulation.
Applying spray foam insulation involves using a spray gun to apply the liquid mixture to the desired surface. Once applied, the foam expands and fills in gaps or cracks, creating a seamless and continuous insulation layer. This tight seal helps to protect against air leakage and improve energy efficiency.
Spray foam insulation is known for its excellent insulation properties. It has a high R-value, which measures its thermal resistance. This means that it can effectively resist the transfer of heat and cold, keeping the indoor temperature more stable and reducing energy consumption.
Types of Spray Foam Insulation
There are two main types of spray foam insulation: open-cell and closed-cell.
Open-cell spray foam insulation comprises not completely closed cells, allowing air to fill the spaces within the material. This type of insulation is less dense and has a lower R-value than closed-cell insulation. However, it is more affordable and provides good sound insulation.
On the other hand, closed-cell spray foam insulation comprises wholly closed cells, making it denser and more rigid. This type of insulation has a higher R-value and provides better moisture resistance than open-cell insulation. It is also more expensive.
