Wet Spray Fiber Insulation comes in variable thickness levels can fill 2×4 cavities up to an R-15 thermal rating, 2×6 cavities up to R-23, and six-inch steel stud cavities up to R-25. The insulation also reduces sound transmission, achieving a Sound Transmission Class of 43 in a standard 2×4 wood-framed wall. The insulation also resists mold because it sprays in almost dry (less moisture content than wood framing), and is treated with a U.S. EPA-registered mold inhibitor to protect the insulation against mold. It can be used for both wall and ceiling applications. In addition, only fiber glass insulation made without formaldehyde and can pass Environmental Specification 1350, the toughest indoor air quality test in North America, with a non-detect for formaldehyde.
Spray-applied cellulose is used for applying cellulose to new wall construction. The differences are the addition of water to the cellulose while spraying as well as adding some kind of moisture retardant such as chlorine to prevent mold cultures. In some cases the insulation might also mix in a very small percentage of adhesive or activate a dry adhesive present in the cellulose. Wet-spray allows application without the need for a temporary retainer. In addition, wet-spray allows for an even better seal of the insulated cavity against air infiltration and eliminates settling problems. Wet-spray installation requires that the wall be allowed to dry for a minimum of 24 hours (or until maximum of 25% moisture is reached) before being covered.
Air leakage, or infiltration, is a major problem in both new and older homes. Besides wasting hundreds of dollars on energy bills, air leakage paths can cause building durability problems, increase the risk of fire spread, permit insect and rodent entry, and create unhealthy indoor air quality. Reducing air leakage usually adds little to the materials’ cost of a house and does not require specialized labor.
Although windows, doors, and outside walls contribute to air leakage, the biggest holes are usually hidden from view and connect the house to the attic, crawlspace, or basement. The key is to identify these areas during the design process, assign responsibility for sealing holes, and check to ensure that the air sealing was done effectively. Usually, seal all the big holes first, then the large cracks and penetrations, and finally the smaller cracks and seams.
Great Care Should Be Taken To Seal The Following Areas:
- any openings or cracks where two walls meet, where the wall meets the ceiling or near interior door frames
- gaps around electrical outlets, switch boxes and recessed fixtures
- gaps behind recessed cabinets and furred or false ceilings such as kitchen or bathroom soffits
- gaps around attic access hatches and pull-down stairs
- behind bath tubs and shower stall units
- through floor cavities of finished attics adjacent to unconditioned attic spaces utility chase ways for ducts, etc., and plumbing and electrical wiring penetrations
Blown insulation is an affordable solution for homeowners seeking superior insulation.
