In addition to absorbing sound, appliance insulation must be thoughtfully designed to prevent thermal transfer. It’s why Johns Manville has been a trusted partner to Original Equipment Manufacturers and fabricators for more than 30 years. Our appliance insulation products are just one more way we demonstrate our commitment to you and the performance on which you depend.
Whether designing for microwaves, ranges, ovens, water heaters, or refrigerators, highly effective insulation can improve the appliance’s operating efficiency and lower its overall operating costs. To help realize these benefits, we provide a wide variety of solutions in a multitude of sizes, densities and forms designed and developed specifically for appliance applications. Each solution can be specially fabricated to make final assembly quicker and easier, and to satisfy your unique thermal and acoustical needs.
Microlite MW & Microlite MW XG
Johns Manville Microlite® MW is a lightweight, highly resilient blanket type thermal insulation made of fine, flame-attenuated glass fibers bonded with a thermosetting phenolic resin. It is specifically designed for use in convection microwave ovens where temperatures do not exceed 500°F (260°C).
Johns Manville Microlite® MW XG is a lightweight, Formaldehyde-free™ blanket type thermal insulation made of fine, flame-attenuated glass fibers bonded with a thermosetting acrylic resin. It is specifically designed for use in convection microwave ovens where temperatures do not exceed 500°F (260°C) and a Formaldehyde-free™ product is desired.

XSPECT ISOfoam APF Board
The XSPECT® ISOfoam APF board is a closed-cell polyisocyanurate foam core bonded to a foil facer on both sides. It is a highly versatile insulation that can be used in a variety of mechanical and OEM applications, including rooftop ducts, appliances, HVAC equipment, refrigerated transportation, storage vessels, and railcars.
XSPECT ISOfoam APF board offers one of the highest R-values of any rigid insulation available, making it ideal for both hot and cold applications. The foil facer on the insulation operates as an excellent vapor-retarder, working in tandem with the closed cell foam to contribute to a tightly sealed system. Additionally, the lightweight foam makes it easy to fabricate and install.
R-Value: R-2.7 - R-26
Thickness: 1" - 4"
