Welding Blankets & Curtains

Industrial Welding Blankets & Curtains for Maximum Thermal Protection

In industrial fabrication, shipbuilding, and heavy construction, protecting personnel and surrounding equipment from extreme heat, sparks, and molten slag is not optional—it is a critical safety requirement. DeBrovys manufactures and supplies a comprehensive line of industrial-grade welding blankets and curtains designed to withstand the most severe thermal environments. Since 1885, we have partnered with professional fabricators to deliver safety solutions that meet or exceed OSHA and ANSI Z49.1 standards. Whether you need a lightweight fiberglass curtain to shield workers from UV/IR arc flash, or a heavy-duty heat-treated blanket capable of withstanding 1,000°F continuous heat during heavy slag operations, our extensive product line ensures you have the exact thermal barrier required for the job.

The distinction between a welding curtain and a welding blanket is primarily determined by its application and orientation. Welding curtains are designed to hang vertically, creating a visual and physical barrier around the welding cell. They block hazardous ultraviolet (UV) and infrared (IR) radiation while deflecting light sparks. Welding blankets, conversely, are designed for horizontal deployment. They are draped directly over equipment, machinery, or structural components to provide intense, direct protection against heavy sparks, spatter, and molten metal slag. DeBrovys offers both solutions in a variety of specialized materials, weights, and custom dimensions to fit your specific facility layout.

Advanced Thermal Materials: Fiberglass, Neoprene, and Silicone

The performance of a welding blanket or curtain is entirely dependent on its base material and specialized coating. DeBrovys utilizes advanced high-temperature fabrics engineered for specific welding processes, from light TIG welding to heavy-duty arc gouging and plasma cutting. Our baseline thermal fabrics are constructed from premium woven fiberglass, which provides exceptional baseline heat resistance and structural integrity. However, raw fiberglass can be abrasive and prone to fraying, which is why we apply specialized coatings to enhance both performance and handling.

For applications requiring a balance of heat resistance and abrasion durability, our Neoprene Welding Blankets are the industry standard. The neoprene coating locks the fiberglass fibers in place, creating a smooth, durable surface that sheds sparks and resists oil and water absorption. For extreme temperature environments, our Heat Treated Fiberglass Blankets undergo a specialized thermal process that burns off organic binders, resulting in a clean, smoke-free fabric capable of withstanding 1,000°F continuous heat. We also offer premium silicone-coated options and specialized acrylic-coated Slag-Shed fabrics for maximum molten metal deflection.

Technical Specifications: Material Selection Guide

Selecting the correct thermal fabric requires understanding the specific temperature thresholds and spark deflection characteristics of each material. Using a light-duty curtain for a heavy-slag application will result in immediate burn-through and potential fire hazards. Use the comparison table below to determine the appropriate DeBrovys material for your specific welding operation.

Custom Fabrication and Installation Accessories

While we stock a vast inventory of standard-sized blankets and curtains for immediate shipment, DeBrovys operates a full custom manufacturing facility in Louisville, Kentucky. We can fabricate thermal barriers to your exact dimensional specifications, complete with custom grommet spacing, reinforced hems, and specialized cut-outs to fit precisely around machinery or structural columns. Every custom blanket is finished with heavy-duty Kevlar or Nomex thread to ensure the seams withstand the same extreme temperatures as the base fabric.

To facilitate easy installation of your vertical safety barriers, we also supply a complete line of curtain hardware, including heavy-duty track systems, nylon rollers, and steel mounting brackets. If your facility requires transparent perimeter protection rather than solid thermal barriers, explore our Insta-Curtains Weld-View line.

Frequently Asked Questions

What is the difference between a welding blanket and a welding curtain?

The primary difference is orientation and intended use. A welding curtain is designed to hang vertically to enclose a workspace. Its main function is to block hazardous UV/IR arc flash from harming bystanders and to deflect light sparks. A welding blanket is designed to be draped horizontally directly over equipment, floors, or vehicles. Blankets are constructed from heavier, more heat-resistant materials designed to catch and hold molten slag and heavy spatter without burning through.

Are DeBrovys welding curtains OSHA compliant?

Yes. Our Insta-Curtains Weld-View vinyl laminate curtains meet OSHA 29 CFR 1910.252 requirements for arc welding and cutting operations, as well as ANSI Z49.1 safety standards. They are specifically tinted to filter out harmful ultraviolet (UV) and infrared (IR) radiation while allowing enough visible light transmission for supervisors to monitor the work area safely.

Which blanket material is best for heavy molten slag?

For applications generating heavy molten slag (such as arc gouging or heavy stick welding), we recommend our 35 oz. Heat Treated Fiberglass or our 32 oz. Silicone Coated Fiberglass blankets. The heavier weight provides the necessary thermal mass to absorb intense heat, while the silicone coating on the 32 oz. variant actively sheds molten metal before it can burn into the base fabric.

Can I wash or clean a fiberglass welding blanket?

We do not recommend machine washing any fiberglass-based thermal blanket, as the agitation can break down the woven fibers and degrade the heat-resistant coatings. For coated blankets (Neoprene, Silicone, or Acrylic), you can gently wipe the surface with a damp cloth to remove dust and light oil. Uncoated or heat-treated fiberglass blankets should only be shaken out or lightly brushed to remove debris.
