ATLANTA SPRAY ON FOAM INSULATION: OPEN CELL AND CLOSED CELL APPLICATIONS
Spray foam insulation also known as polyurethane spray foam insulation is often categorized as either “open-cell” or “closed-cell”. Spray polyurethane foam (SPF) is a highly-effective and widely used insulation and air sealant material. Spray foam insulation can be sprayed into walls, ceilings, floors, crawls paces and attics to reduce energy waste and reduce heating and cooling costs in both new and existing homes. The main differences between open and closed cell foam are moisture permeability, R-value, and flexibility. Closed cell foam is an air barrier & a moisture vapor barrier. This means that it will not allow moisture to pass through the foam. Open cell foam is an air barrier at a specific thickness but is not a moisture vapor barrier, and will allow moisture to pass. The best foam to use should be determined by the application not the R-value.
OPEN CELL SPRAY ON FOAM INSULATION:
Aladdin’s professionally Open-cell spray foam (JM ocSPF) is a low-density, non structural insulation that offers a high yield while still providing important air isolation, versatile R-values, excellent acoustical performance. Open-cell foam costs slightly less for the same thickness, but offers lower per-inch R-values than closed-cell products. In some instances, this is a disadvantage, but where thickness is less relevant, or where higher R-values are not needed, then open-cell can provide the better choice. Because of the open cell structure, open-cell foam allows some vapor to pass through, making it a good choice in hot, humid climates, and under roof sheathing, such as in conditioned attics, where water vapor caught between insulation and sheathing could promote wood rot. When installed at a thickness of 1″ inch, it provides an R-value of 3.8, R-13 at 3.5″ inches, and R-19 at 5.5″ inches.
OPEN CELL SPRAY FOAM BENEFITS:
- Spray in place insulation and air barrier
- Vapor permeable
- Will accommodate long term creep and seasonal movements
- Typical R-value of 3.6 per inch
- Increase comfort & efficiency
- Suitable for interior applications only                              Â
- Soft open cell structure allows for greater sound
absorption versus closed cell structure
OPEN CELL APPLICATIONS:
- Underside Of Roof Deck (Unvented Attic)
- Exterior And Interior Walls
- Attic Floor (Vented Attic)
- Knee walls
- Cathedral ceilings
- Crawl Spaces
CLOSED CELL SPRAY ON FOAM INSULATION:
Aladdin’s professionally installed Closed Cell polyurethane spray foam is among the most efficient insulating materials commercially available, with R-values commonly around 6.0 per inch. Closed-cell foam incorporates an insulating gas that is retained within the cells (foam “blowing agent”), which leads to the highly efficient insulating properties of the material. It provides both a vapor and air barrier and offers an aged R-value of a whopping 6.0 up to 6.5 per inch. The dense polyurethane foam insulation is extremely durable, expanding and fully adhering to surfaces, strengthening the structure of a home. It provides incredible thermal performance and can be installed in areas that would be inaccessible or difficult for other forms of insulation
CLOSED CELL SPRAY FOAM BENEFITS:
- Spray in place insulation and air barrier
- Low vapor permeance
- Vapor barrier
- Rigid design adds structural reinforcement
- Will stay in desired location
- Rejects bulk water (even submerged)
- Typical R-value of 6.0 per inch
- Suitable for both interior and exterior applications
CLOSED CELL APPLICATIONS:
- Inerior and Exterior Applications
- Metal Duct Work
- Attic Floor
- Walls
- Knee walls
- Crawls paces
- Commercial Building Roof
