Closed-cell spray foam insulation is a dense, rigid foam that expands upon application to create an air and moisture barrier. It has a high R-value per inch, providing strong thermal resistance and structural reinforcement.
Closed-cell foam is denser and has a higher R-value, making it better suited for areas requiring moisture control or added strength. Open-cell foam is lighter and more flexible, typically used for interior walls where sound absorption is a priority.
Closed-cell spray foam typically offers an R-value of around 6 to 7 per inch. This makes it one of the most effective insulation types for energy efficiency.
Yes, it is suitable for both residential and commercial applications. It is often used in walls, roofs, crawl spaces, and basements for its high insulation performance and moisture resistance.
It is water-resistant and acts as a moisture barrier, but it is not entirely waterproof. It helps prevent water vapor and humidity from penetrating the insulated area.
Yes, once cured, closed-cell foam adds rigidity and structural strength to walls, roofs, and other building elements. This can improve overall building durability.
With proper installation, it can last the lifetime of the structure. It does not sag, settle, or degrade under normal conditions.
When installed by professionals following safety guidelines, it is safe. Off-gassing primarily occurs during installation, and re-entry is safe after proper ventilation and curing.
The thickness depends on the area and insulation goals. Typically, 2 to 3 inches is sufficient for walls, while roof decks might require more for code compliance.
Most residential installations take one to two days, depending on the size and complexity of the project. Larger or more intricate jobs may require additional time.
In some cases, yes, but the existing material must be dry and in good condition. A professional assessment is needed to determine compatibility.
Closed-cell spray foam significantly reduces air leakage, leading to lower heating and cooling costs. It helps maintain consistent indoor temperatures throughout the year.
It provides some sound dampening, but not as effectively as open-cell foam. Its density does reduce noise transfer to a certain extent.
Costs vary by project size and location but generally range from $1.00 to $1.50 per board foot. A detailed estimate is provided after an inspection.
Some energy efficiency programs may offer rebates or tax credits. Local guidelines and federal programs should be reviewed for current opportunities.
Closed-cell spray foam requires minimal maintenance. Regular home inspections are recommended to check for any structural changes that may affect insulation.
Removal is possible but can be labor-intensive. Modifications often require cutting out sections and replacing them, which should be done by professionals.
