Product Description

Product Overview

Glass wool board is a high-performance thermal and acoustical insulation material designed for residential, commercial, and industrial building applications. Composed of fine inorganic glass fibers bonded with fire-retardant thermosetting resin, these boards provide exceptional insulation properties.

Applications

Exterior and interior wall insulation
Cavity wall construction and partitions
Floor insulation and precast structures
Duct work and mechanical system insulation
Vessel and tank insulation where abuse resistance is required
Prefabricated housing applications
