Fiberglass Welding Blankets | Weld Armor Heat Cleaned Fiberglass
Steel Guard’s Weld Armor fiberglass welding blankets are the economical choice for everyday MIG, TIG, and stick welding protection. Made from 18 oz heat cleaned fiberglass and rated to 1,000°F, Weld Armor blankets reliably protect against sparks, spatter, arc flash, and solvent exposure in standard welding shop environments. Heat cleaned fiberglass removes the binder coating from the fibers — improving flexibility, temperature resistance, and overall blanket performance compared to standard fiberglass.
Every Weld Armor blanket is sewn with high-heat thread and includes grommets set every 24″ on all sides for secure hanging and attachment in both horizontal and vertical applications. All blankets meet FM Global and NFPA-701 flame retardancy certifications. Custom sizes available on request. Part of the Steel Guard welding blanket lineup — compare all materials to find the right protection level for your application.

Additional Information:
What Is Heat Cleaned Fiberglass?
Standard fiberglass fabric is manufactured with a sizing or binder coating applied to the fibers to aid in weaving. For welding blanket applications this binder reduces temperature resistance and flexibility. Heat cleaned fiberglass goes through a high-temperature process that burns off this binder coating — resulting in a cleaner, more flexible fabric with improved temperature resistance and better performance in welding environments. All Steel Guard Weld Armor blankets use heat cleaned fiberglass rather than standard binder-coated fiberglass.
Weld Armor Fiberglass Welding Blanket Applications
- MIG, TIG, and stick welding spark and spatter protection
- Arc welding heat shield barriers
- Equipment and machinery protection during welding operations
- Floor and surface protection from weld slag and spatter
- Vertical curtain applications in welding bays and fabrication areas
- Pipe and structural steel protection during welding
- Heat treating applications using multiple blanket layers
- Solvent exposure protection in welding environments
When Fiberglass Is the Right Choice
Fiberglass welding blankets are the right choice for the majority of everyday welding shop applications. Choose Weld Armor fiberglass when:
- Your application involves standard MIG, TIG, or stick welding at typical shop temperatures
- You need reliable spark and spatter protection at the most economical price point
- Surface scratching is not a concern — protecting steel, concrete, or non-finished surfaces
- You need stock sizes available for fast shipment in 2–3 business days
If your application involves extreme temperatures, scratch-sensitive surfaces, or heavy abrasion, consider upgrading to a higher-performance material in our lineup.

Weld Armor fiberglass welding blankets are rated to 1,000°F. This makes them suitable for standard MIG, TIG, and stick welding applications, arc welding heat shielding, and light heat treating with multiple layers. For continuous exposure above 1,000°F our silica or carbon fiber welding blankets provide higher temperature ratings.
Heat cleaned fiberglass is standard fiberglass fabric processed at high temperature to remove the sizing or binder coating applied during manufacturing. This results in improved flexibility, better temperature resistance, and cleaner performance in welding environments compared to standard binder-coated fiberglass. All Weld Armor blankets use heat cleaned fiberglass.
Fiberglass fabric is made from very fine glass fibers that can cause skin irritation and itching on contact. Always handle fiberglass welding blankets with work gloves to protect your hands and forearms. If you prefer a blanket that does not require gloves for handling, our Knight Armor carbon fiber felt welding blankets have a soft scratch-free surface with no irritation.
Yes — Weld Armor fiberglass welding blankets can be used in heat treating applications when multiple layers are used together. For dedicated heat treating applications requiring sustained high-temperature coverage, our White Spark silica blankets are the preferred choice with a continuous 1,800°F rating.
- Fiberglass welding blankets are the economical choice for standard welding temperatures — ideal for everyday MIG, TIG, and stick welding protection. Silica welding blankets are engineered for higher continuous temperature exposure — particularly heat treating, foundry work, and furnace applications where fiberglass reaches its performance limits.
