JM Spider Insulation Reduces Outside Noise

JM Spider insulation sprays in to fill gaps and voids where noise can travel into the home. For example, JM Spider insulation achieves a Sound Transmission Class (STC) of 43 in an exterior 2×4 wood framed wall with 1/2″ particle board siding, 1/8″ pressed cardboard sheathing and 1/2″ gypsum board. Compare JM Spider insulation with other systems, and you’ll see that it is the best choice for reducing sound transmission. Homeowners will enjoy more peace and quiet in their new home.

JM Spider Insulation Adds a Layer of Protection Against Mold

There has been a rising concern over some spray insulation systems that use water, which and can be a food source for mold. JM Spider insulation is made from fiberglass, an inorganic material that is naturally mold resistant.

In addition, JM Spider insulation adhesive contains a U.S. EPA registered mold inhibitor, giving the insulation an additional layer of protection against the growth of mold, and thus improving the quality and durability of the homes you build.

JM Spider insulation sprays on practically dry to the touch, using less than 8 oz of moisture per cavity in the adhesive while some other systems use more than 32 oz of water per cavity! In fact, JM Spider insulation can contain even less moisture than the surrounding wood framing.

JM Spider Insulation Saves Money and Reduces Cycle Time

JM Spider insulation needs no drying time when installed with the recommended amount of moisture. You can be done with the job in just one day! You can put drywall up right away, while other upgrade spray systems may take 2-3 days to prep, install and dry.
