Finding the best insulation for your home is crucial. Johns Manville® insulation helps improve your home’s energy efficiency by trapping air in the fiberglass, so you can keep cool in the summer and warm in the winter. Plus, Johns Manville is a partner of the ENERGY STAR Seal and Insulate program and is both GREENGUARD Gold Certified and SCS Certified for indoor air quality.
Johns Manville® fiberglass insulation, available in batt, rolls and blow-in, won’t corrode pipes, wiring or metal studs and doesn’t contain formaldehyde - protecting your family from chemicals leeching into the air. Johns Manville Attic Protector® blow-in insulation provides complete coverage by filling in the nooks, crannies and hard to reach areas, and is fire-resistant. It also won’t settle and lose R-value (a rating of how well the insulation will resist heat), keeping your house properly insulated. This insulation won’t rot, mildew, deteriorate or provide food for animals. Johns Manville AP™ Foil-Faced Polyiso Foam Sheathing is available in R-values up to R-28 and offers exceptional heat, moisture and air control. This sheathing eliminates all major thermal bridges that cause heat loss, providing maximum coverage for energy loss. Best of all, McCoy’s carries Johns Manville insulation in stock, so you have access to what you need, when you need it.
