JM SPIDER® CUSTOM INSULATION SYSTEM
Johns Manville Spider® Custom 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. JM Spider® insulation also reduces sound transmission, achieving a Sound Transmission Class of 43 in a standard 2×4 wood-framed wall.
JM Spider® insulation resists mold because it sprays in almost dry and is treated with a U.S. EPA-registered mold inhibitor to protect the insulation against mold. JM Spider® insulation can be used for both wall and ceiling applications. In addition, only fiber glass insulation made without formaldehyde—such as JM Spider® Custom Insulation—can pass Environmental Specification 1350, the toughest indoor air quality test in North America, with a non-detect for formaldehyde.
SPIDER Insulation is very good at fitting around items in walls like pipes and wiring, leaving no air pockets that can reduce the overall efficiency of the wall. Dense pack SPIDER produced by Johns Manville can seal walls from air infiltration while providing the density to limit convection, when installed properly. It is made of recycled glass content with a clean, white appearance and uniform texture. Unlike dense pack cellulose, SPIDER applies with less moisture than the wood framing in homes, dries fast for quick sheetrock installation with no concerns of moisture and guarantees not to sag over time.
