ATLANTA SPRAY ON FOAM INSULATION: OPEN CELL AND CLOSED CELL APPLICATIONS<\/a><\/strong><\/span>
\nSpray 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.<\/p>\n

OPEN CELL SPRAY ON FOAM INSULATION:<\/a><\/strong><\/span>
\nAladdin’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.<\/p>\n
