JM Spider Custom Insulation System
Johns Manville Spider® Custom Insulation is a spray applied fiberglass that is installed with an adhesive. Spider provides high thermal performance as exemplified by its ability to achieve an R-15 in a 2x4 cavity and an R-23 in a 2x6 cavity. JM Spider® insulation also reduces sound transmission, achieving a Sound Transmission Class of 43 in a standard 2x4 wood-framed wall. JM Spider® insulation 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. 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.
JM Spider insulation:
- Custom fits every cavity filling in gaps around wiring, plumbing and ducts.
- Delivers high performance thermal insulation and effective R-value.
- Doesn't sag, settle, or shrink.
