Spray Foam Insulation
Spray Foam Insulation is a versatile material and proven solution to a variety of construction challenges like:
- Creating of a complete air barrier
- Controlling moisture and condensation
- Stopping rodent and insect intrusion
- Preventing mold
- Inhibiting ice formation
- Eliminating squeaky building components
- Reducing convective currents in walls or attics
- Reducing outside noise
- Adding structural strength
All these benefits translate into:
- Energy efficiency (a high R-value per inch)
- Cost-savings, it reduces the cost of installing multiple products to achieve one thing
- Peace of mind, it keeps unwanted things out
OPEN CELL AND CLOSED CELL
The selection of Open Cell SPF versus Closed Cell SPF depends on the project and what is needed in terms of its performance or specific application requirements.
Open Cell SPF produces cells which do not completely close when applied. Air is allowed to fill the space inside the material. It is often installed in the same way unfaced-fiberglass insulation is used. In terms of cost and R-value, Open Cell SPF is the more efficient use of polyurethane foam. In other words, as an air barrier, it uses minimal material to create maximum affect.
Closed Cell SPF produces tiny cells that are completely closed making it a denser, heavier, and stronger material. Its composition is better for preventing vapor and moisture penetration. It is often used in basements, crawlspaces, unvented cathedral ceilings, wine cellars, and other areas of high moisture potential. Despite the higher R-value, Closed Cell SPF requires more material, is more expensive and has a higher cost per R-value.
