About Selecting Wool Felt

Fiberglass Fabric Sheets and Strips

Commonly used as curtains and in sealing applications.

Wet-and-Stick Fiberglass Fabric Sheets and Strips

Similar to plaster, these adhesive-impregnated sheets and strips become moldable when water is added and harden as they dry. They can be used in sealing, insulating, and covering applications.

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.

Very High-Temperature
Vermiculite-Coated Fiberglass Fabric

Resistant to sparks and molten metal spatter, this fabric withstands temperatures up to 1000° F. It's often used for curtains, blankets, and gaskets.

Static-Control PTFE-Coated Fiberglass Fabric Sheets

These sheets can be grounded to reduce static electricity.

Tear-Resistant PTFE-Coated Fiberglass Fabric Sheets

These sheets are 50% more tear resistant than other fiberglass fabric sheets.

PTFE-Coated Fiberglass Mesh Fabric Sheets

With larger openings than porous fiberglass fabric, these sheets allow for more air circulation in drying applications.

PTFE-Coated Fiberglass Fabric Sheets

The PTFE coating makes these fiberglass sheets nonstick and chemical resistant.

Porous PTFE-Coated Fiberglass Fabric Sheets

Pores allow for air circulation, so these sheets are often used in drying applications.

Heat-Deflecting Foil-Backed Fiberglass Fabric

Often used to create curtains and screens, this fabric has an aluminum foil backing that deflects radiant heat.

Mildew-Resistant Aramid/Fiberglass Blend Fabric

A blend of aramid and fiberglass, this fabric resists mildew and abrasion. It is self-extinguishing and won't melt, so it's often used for insulation applications.

Abrasion- and Heat-Resistant
Acrylic-Coated Fiberglass Fabric

This abrasion-resistant fabric sheds molten metal spatter when placed at an incline of 15° or greater. Use as a welding curtain.

Flexible Silica Fabric Sheets and Strips

More flexible than standard silica fabric, wrap these sheets and strips to insulate pipes, wires, and hose. This fabric also protects against welding spatter.

Silica Fabric Sheets

Commonly used as curtains, covers, insulation, and splash shields, these sheets protect against welding spatter.

Fire-Retardant Carbon Fiber Sheets

Even when exposed for as long as 2 minutes to temperatures up to 2600° F, these sheets won't ignite or melt.

Carbon Fiber Fabric Strips

Use these strips for high-temperature seals and heat insulation.

Nomex Aramid Fabric Sheets

Lighter than Kevlar, Nomex is often used for temperature-resistant garments.

Fabric

Velvet Fabric

This low-pile velvet cushions and damps vibration.

Flame-Resistant Cotton Fabric Sheets

This cotton fabric is treated to resist flames. Use as tarps.

Water-Repellent Cotton Fabric Sheets

Saturated with wax, these sheets also have a polyester coating on one side to resist corrosion and moisture. Protect piping and wrap irregularly shaped objects with this very flexible fabric.

Felt

High-Temperature Felt

This Nomex aramid felt withstands temperatures three times as high as wool felt. It is chemical resistant and often used as insulation.

Synthetic Felt

This synthetic felt is an economical alternative to wool felt.

Soft Felt Sheets and Strips

Soft Felt Lining Sheets

Line toolboxes and drawers to cushion and protect small parts.

Firm Felt Sheets and Strips

Firm Felt Discs

Firm Felt Cords

Hard Felt

Made of 100% wool, this is the hardest felt we offer, yet it can still be used for polishing. It is more abrasion resistant and better at damping vibration than other felt. Includes S2-32, S2-24, and S2-20 felt grades.

High-Strength Basalt Pipe Insulation

Superior in strength and durability, these thin strips insulate as well as protect personnel from accidental contact with hot pipes. Use for exhaust, hot water, and process pipes.
