Welding Blankets & Curtains
The Complete Guide to Welding Blankets and Welding Curtains
Whether you are protecting adjacent equipment from welding sparks, partitioning a fabrication floor for OSHA compliance, or covering sensitive components during hot work, selecting the right welding blanket or welding curtain is a critical safety decision. DeBrovys has manufactured industrial-grade welding protection equipment since 1885, supplying fabricators, shipbuilders, contractors, and industrial maintenance teams across North America.
This page is your complete resource for understanding the different types of welding blankets and curtains available, how to select the right product for your application, and what the 2026 OSHA and ANSI standards require. Use the navigation below to jump directly to the product category you need.
Welding Blanket Types: Which Coating Is Right for Your Application?
Not all welding blankets are created equal. The base material — woven fiberglass — is consistent across most industrial welding blankets, but the coating determines the blanket's performance in specific environments. Choosing the wrong coating means premature failure, increased replacement costs, and potential OSHA compliance gaps. Here is how each coating type performs:
| Blanket Type | Continuous Temp | Key Advantage | Best Application |
|---|---|---|---|
| Vermiculite Coated | Up to 1,800°F | Superior heat & abrasion resistance; handles heavy spatter | Foundry work, plasma cutting, heavy structural welding |
| Aluminized Fiberglass | Up to 1,500°F | Reflects radiant heat away; reduces ambient temperature rise | Furnace work, high-radiant-heat environments, pipe insulation |
| Neoprene Coated | Up to 1,000°F | Resists oil, water, and chemicals; does not absorb liquids | Outdoor construction, shipyards, automotive & equipment repair |
| CH-Grade Silica Cloth | Up to 1,800°F | Highest continuous service temperature; low thermal conductivity | Glass manufacturing, ceramics, aerospace, extreme heat applications |
| Heat Treated Fiberglass | Up to 1,200°F | Clean, smoke-free; binder removed for reduced outgassing | Food processing, clean rooms, semiconductor manufacturing |
Welding Curtains: OSHA Compliance and UV/IR Protection
While welding blankets protect horizontal surfaces and equipment, welding curtains create vertical barriers that protect bystanders and adjacent workers from UV radiation, infrared radiation, and welding spatter. OSHA Standard 29 CFR 1910.252(b)(2)(i) requires that welding operations in areas where other workers are present must be shielded by "non-combustible or flameproof screens or shields."
DeBrovys Insta-Curtains Weld-View vinyl laminate welding curtains meet this requirement and are available in three ANSI Z49.1-compliant colors — Red (shade 3), Gold/Yellow (shade 5), and Blue/Purple (shade 8) — each providing a different level of UV/IR filtration appropriate for different welding processes.

How to Choose the Right Welding Blanket: A Decision Framework
The correct welding blanket selection depends on four key variables: the temperature of the welding process, the environment (indoor vs. outdoor, presence of liquids), the duration of exposure (continuous vs. intermittent), and the specific hazard being guarded against (sparks, spatter, radiant heat, or chemical exposure).
| Your Situation | Recommended Blanket |
|---|---|
| Heavy structural welding, foundry, or plasma cutting with high spatter volume | Vermiculite Coated (20 oz., 27 oz., or 40 oz.) |
| Outdoor welding, shipyard, or any environment with oil/water/chemical exposure | Neoprene Coated (17 oz. Salmon) |
| Furnace work, boiler maintenance, or high radiant heat environment | Aluminized Fiberglass (18 oz.) |
| Extreme continuous heat above 1,200°F or aerospace/glass manufacturing | CH-Grade Silica Cloth |
| Clean room, food processing, or semiconductor environment | Heat Treated Fiberglass |
| General purpose indoor welding with moderate sparks and spatter | Vermiculite Coated 20 oz. (most popular all-around choice) |
OSHA Requirements for Welding Blankets and Fire Protection (2026)
OSHA 29 CFR 1910.252 — the primary standard governing welding, cutting, and brazing in general industry — requires that combustible materials within 35 feet of a welding operation must either be removed or protected by fire-resistant shields. Welding blankets serve as those shields.
The 2026 enforcement landscape has tightened around hot work permit compliance, particularly in facilities subject to NFPA 51B (Standard for Fire Prevention During Welding, Cutting, and Other Hot Work). Key requirements include:
- Blankets must be fire-resistant, not merely fire-retardant — a distinction OSHA inspectors now actively enforce
- Blankets must remain uncontaminated — an oil-saturated uncoated fiberglass blanket may be cited as non-compliant; neoprene-coated blankets eliminate this risk
- Blankets must be properly sized to cover all combustible materials within the work zone
- Hot work permits must document the specific protective measures in place, including blanket type and coverage area
All DeBrovys welding blankets meet the fire-resistant shield requirements of OSHA 29 CFR 1910.252 and ANSI Z49.1. For documentation requests, contact our team.
Welding Blanket Sizes: Standard and Custom
DeBrovys manufactures welding blankets in standard sizes from 4×6 ft through 12×12 ft, with larger custom sizes available for equipment coverage, pipeline protection, and structural applications. Standard sizes ship within 1–3 business days. Custom sizes — including non-standard dimensions, custom grommet spacing, and reinforced edges — typically ship within 5–7 business days with no minimum order requirement.
Common standard sizes available: 4×6, 4×8, 6×6, 6×8, 8×8, 8×10, 10×10, 10×12, 12×12 ft. All blankets include brass grommets every 24 inches along all edges for easy hanging and securing.
