SPRAY FOAM
SPRAY FOAM
Closed-cell spray foam is a high-performance insulation solution designed to improve energy efficiency, control air leakage, and protect your home or building from moisture intrusion. With an aged R-value of over R-7.5 per inch when using HFO-blown foam, its millions of tiny closed cells provide excellent thermal resistance, low water vapor permeability, and strong water resistance.
When properly installed, closed-cell spray foam can help reduce energy use by up to 45%, depending on the building and existing conditions. By sealing gaps, cracks, and hard-to-reach spaces, it helps minimize unwanted air infiltration, heat transfer, and moisture-related issues while adding rigidity to the building structure.
WHAT IS SPRAY FOAM?
When space is limited, closed-cell spray foam can help you achieve higher R-values with less thickness than many traditional insulation materials. With an R-value of over R-7.5 per inch, it can be an effective solution for projects where wall cavities, roof assemblies, or other spaces limit insulation depth.
Beyond thermal performance, closed-cell spray foam provides additional benefits:
Air Barrier: Helps seal gaps and reduce unwanted air leakage.
Moisture Resistance: Helps limit moisture intrusion when properly installed as part of an appropriate building assembly.
Structural Support: Adds rigidity and strength to certain building assemblies.
Our team can help you explore insulation options that fit your project's space requirements and applicable building codes.
CAN’T REACH R-VALUE?
Air leaks can occur throughout your home or building, allowing conditioned air to escape and outside air to enter. Without effective insulation and air sealing, your heating and cooling systems may have to work harder, increasing energy consumption and utility costs.
Spray foam insulation helps address these issues by creating a more consistent thermal envelope, sealing hard-to-reach gaps, and improving overall building performance.
The benefits of spray foam insulation include:
Reduced Air Leakage: Seals gaps and cracks where unwanted air can enter or escape.
Improved Energy Efficiency: Helps maintain comfortable indoor temperatures and reduce heating and cooling demands.
Long-Term Savings: Can help lower energy costs over time.
Added Structural Rigidity: Closed-cell foam can add strength to certain building assemblies.
Moisture Resistance: Helps protect against moisture intrusion when installed as part of a properly designed building system.
