Spin-Glas® is a rigid, board-type fiberglass insulation manufactured from fine, rotary-process glass fibers bonded with a special thermosetting resin. This fiberglass insulation provides superior thermal and acoustical capabilities. It is ideal for use in applications requiring strength and durability, high thermal and acoustical values, space adaptability and attractive appearance.


Spin-Glas® is well-suited for use in office partitions, ceiling panels, wall panels, and HVAC equipment in an effort to reduce thermal transfer and sound transmission. Because the glass fibers in Spin-Glas® are extremely fine, they create an enormous number of minute air spaces, making this fiberglass insulation highly effective for sound and heat absorption.

This product is available plain, FSK-faced or coated for use in a variety of applications.


Spin-Glas® fiberglass board is resistant to the effects of moisture, oil, grease and most acids. Because these fibers are highly resilient, they resist settling, break down, or sagging from vibration. They yield readily to impact and protect facings from puncture or tearing.

The properties of this product assure ease of application. It can be readily cut with a knife and secured with mechanical fasteners or adhesives. This fiberglass insulation product can be faced with a variety of products to meet airstream requirements.
