JM Spider® Custom Insulation System Exclusively by Magnus Insulation and Fireproofing.

JM Spider insulation with BIBS creates a consistent thermal barrier that minimizes energy loss in areas such as exterior walls, vaulted ceilings, bonus rooms and unvented attic assemblies. Because of the size and dimension of the JM Spider fiber, when densely packed, thermal protection increases over open-cell foam and cellulose.

JM Spider insulation saves money and reduces cycle time.
JM Spider insulation needs no drying time if you install it with the recommended amount of moisture, so you can put drywall up right away. Other upgrade spray systems can take two to three days to prep, install and dry. With JM Spider insulation, you can be done in one day.
