Closed-cell spray foam is a type of insulation made from polyurethane that expands upon application to form a rigid, dense barrier. It has a higher R-value per inch than many other insulation types, offering strong thermal resistance and moisture control.
Closed-cell foam is denser and provides a better air and moisture barrier compared to open-cell foam. It also has a higher R-value, adds structural strength to buildings, and is more resistant to water and vapor.
Closed-cell spray foam typically has an R-value between 6.0 and 7.0 per inch, making it one of the most efficient insulation materials available.
Closed-cell spray foam is highly resistant to water and acts as a vapor barrier. While not fully waterproof in all applications, it significantly reduces the risk of moisture intrusion.
Yes, it seals air leaks and provides continuous insulation, reducing heating and cooling costs by minimizing energy loss through walls, roofs, and floors.
It can be used in attics, crawl spaces, walls, basements, and roofs. It is suitable for both residential and commercial buildings.
Properly installed closed-cell spray foam can last over 30 years without needing replacement, maintaining its insulating properties over time.
Yes, it adds rigidity and support to walls and roofs due to its dense, hardened composition once cured.
After curing, closed-cell spray foam is inert and does not emit harmful fumes. Proper ventilation during installation is important for safety.
The ideal thickness depends on the application area. In most cases, 2 to 3 inches are sufficient for effective thermal and air barrier performance.
Yes, it is often used to upgrade insulation in older buildings, improving efficiency without the need for full-scale renovations.
It is applied using a spray gun operated by trained professionals. The foam expands and hardens quickly after contact with the surface.
It is not fireproof but can be treated with fire retardants. Building codes may require a thermal barrier or ignition barrier over the foam in certain areas.
Costs vary by project size and location but typically range from $1.00 to $1.50 per board foot, not including labor. An on-site estimate provides more accurate pricing.
While it has some soundproofing qualities, it is not as effective at noise reduction as open-cell foam. Its primary benefit is insulation and moisture control.
Once installed, it requires little to no maintenance. Periodic inspection of areas prone to structural movement or damage is recommended.
Closed-cell foam offers higher R-values, air sealing, and moisture resistance. Fiberglass is less expensive but does not provide the same level of performance.
