CLOSED CELL FOAM INSULATION
Knoxville, Maryville, & East Tennessee
Closed-cell spray foam insulation is one of the most efficient insulating materials commercially available, with aged R-Values above 6.0 per inch.
As an industry leader in high-performance spray foam insulation, Lapolla strives to raise the bar in energy efficiency and sustainable building practices.
The description “closed-cell” comes from the cell structure of the finished insulation material. One cubic inch of polyurethane foam insulation contains millions of tiny plastic closed cells filled with Enovate® 3000, a non-ozone depleting blowing agent.
The blowing agent is captured within the cells which contributes to highly efficient insulating properties. In addition, closed-cell foam provides an inherent air barrier with low moisture vapor permeability, and excellent resistance to water. The density for closed-cell spray foam is approximately two pounds per cubic foot. The medium density foam provides sheer and racking strength to wall assemblies in building applications.
Closed-cell spray foam insulation systems, when properly installed, deliver energy savings of up to 45%.
Small imperfections in the building envelope (holes, cracks, gaps) not properly sealed will eventually lead to poor building performance or worse, moisture accumulation, allergen/pathogen growth, and very possibly structural failure. The solid nature and sealing capability of closed-cell spray foam, inhibits moisture-driven elements. Two inches of closed-cell spray polyurethane foam insulation will minimize air infiltration, exfiltration, convection, conduction and control solar driven moisture in the building envelope.

Adding Spray Foam Insulation To Your Home Can Save You Money Year After Year
The bond that spray foam insulation forms can increase a building’s resistance to wind uplift. During periods of high wind, a building with a spray foam roof generally experiences less damage than a building without SPF. One prominent spray foam technical consultant notes that “when added to the inside of a structure, spray foam ‘glues’ the whole building together, enhancing overall wind and pressurization resistance. SPF insulation adds strength and resilience. The Federal Emergency Management Agency (FEMA) has classified SPF insulation as highly resistant to floodwater damage, saying, “These materials can survive wetting and drying and may be successfully cleaned after a flood to render them free of most harmful pollutants.”
Spray Foam and the Indoor Environment SPF can make your home or build more comfortable in many ways. Spray foam helps minimize airborne sound transmission. As professional, spray foam insulation contractors we’ll seal a building’s air leaks to prevent drafts, creating a more comfortable indoor environment, and providing better indoor temperature control. Closed-cell spray foam acts as a barrier to water and vapor, helping to prevent condensation and water intrusion. Sealing gaps with spray foam can provide a barrier against pollen, dust, and insects, which can be especially helpful in households with allergy sufferers.
Spray Foam Insulation can also be beneficial in fire prevention, as we saw with this client in July 2021.
