Fiberglass Insulation Materials

Fiberglass Insulation Materials are manufactured from extremely fine silica-based glass fibers and various bonding agents. These Materials offer excellent thermal Insulation, nose reduction, and heat resistant properties up to 1200 degrees F depending on the particular material selected. Fiberglass products come in Blanket, Board, and Nonwoven forms and are available with foil laminate skin for additional thermal shielding.

Fiberglass Blanket Materials (available with or without foil and other backing Materials)

fiberglass blanketSG Series Spin-Glas® a Johns Manville Product appliance Insulation, is an efficient thermal and acoustical Blanket made from rotary-process glass fibers bonded with a thermosetting resin. This product was developed specifically for freezers, refrigerators, and other low and medium temperature appliances operating up to 350° F (177° C). Also ideal for use in double-wall HVAC equipment.

The range of density and thickness of SG Series Spin-Glas permits the optimization of thermal, acoustical, and space requirements. These resilient fiber glass Blankets resist damage and are easily cut with a knife, shear, or steel rule die. The Blankets do not contribute to or absorb odors and carry UL Fire Hazard Classification 25/50. The Insulation readily conforms to curved and irregular shapes.

SG Series Spin-Glas is available in rolls in a wide range of thicknesses and densities. Densities are adjusted to meet thermal conductivity requirements.
