Flame-Retardant FRP Fiberglass Sheets and Bars

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

Flame-Retardant FRP Fiberglass 90° Angles

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

Arc-Resistant Garolite G-9 Angles

Machine these angles into arc barriers, switch mounts, and components for circuit breakers and electrical equipment. They resist carrying electric currents in dry or humid areas, even when exposed to sudden electric discharge.

Arc-Resistant Garolite G-9 Rods

Frequently called electrical-grade Garolite, this Garolite G-9 is strong, electrically insulating, and arc resistant in dry environments.

Oil- and Heat-Resistant
Silicone-Coated Fiberglass Fabric

In addition to being oil resistant, this fabric protects against molten metal spatter when used vertically. Use as a heat shield or a welding curtain.

Flexible Metal Conduit for Fiber Optic Cable

Protect fiber optic cable with this small-diameter conduit.

Thermal Insulation

Fiberglass Insulation Sheets

These lightweight flexible fiberglass sheets are typically used to insulate equipment and appliances.

Quick-Install Fiberglass Pipe Insulation

Hook-and-loop fasteners make it easy to install, remove, and reuse this flexible insulation. Use on steam, hot water, and process pipes and fittings.

Fiberglass Building Insulation Sheets and Strips

Also known as batts, these fiberglass sheets and strips are used to insulate walls, ceilings, and floors.

Fiberglass Stair Treads

These lightweight fiberglass treads are corrosion resistant, nonconductive, and nonmagnetic.

Strut Channel Framing and Fittings
