Vermiculite Coated Fiberglass Welding Blanket – High-Temperature Welding & Fire Protection
Product Overview
The Vermiculite Coated Fiberglass Welding Blanket is a high-temperature protective blanket designed to shield personnel, equipment, and surrounding areas from sparks, spatter, molten metal, and radiant heat generated during welding and hot work operations.
Manufactured from woven fiberglass fabric and coated with vermiculite, this welding blanket offers enhanced heat resistance, improved abrasion durability, and reduced fiber shedding compared to uncoated fiberglass blankets. It is widely used in industrial welding, metal fabrication, shipbuilding, construction, and maintenance environments where fire risk control is essential.
Key Features & Benefits
-
High resistance to welding sparks, spatter, and molten metal
-
Vermiculite coating enhances heat resistance and surface durability
-
Reduced fiberglass dust and improved handling comfort
-
Flexible and easy to drape over equipment or work areas
-
Suitable for both indoor and outdoor welding applications
-
Available in multiple sizes, thicknesses, and weights
Material & Construction
The welding blanket is constructed from high-quality E-glass fiberglass fabric, uniformly coated with vermiculite on the surface. The vermiculite coating improves:
-
Resistance to surface abrasion and wear
-
Protection against molten metal splash
-
Dimensional stability under high temperatures
This construction makes the blanket more durable and longer-lasting in demanding welding environments.
Typical Applications
The Vermiculite Coated Fiberglass Welding Blanket is commonly used for:
-
Welding and cutting operations (MIG, TIG, stick welding)
-
Protection of nearby machinery, cables, hoses, and floors
-
Fire prevention during hot work maintenance
-
Shipbuilding and offshore fabrication
-
Construction sites and metal workshops
Thermal Performance
-
Designed to withstand short-term exposure to sparks and molten metal
-
Provides effective shielding from radiant heat
-
Suitable for high-temperature industrial welding environments
Note: This product is intended for welding and fire protection. It is not designed as a continuous thermal insulation blanket.
Engineering Insight: Common Welding-Related Risks & Protection
Risk 1: Spark and Spatter Ignition
Cause:
Welding sparks and molten metal droplets can ignite nearby combustible materials.
Risk:
Fire hazards, equipment damage, and workplace safety incidents.
Protection Provided:
The vermiculite-coated surface resists molten metal splash and prevents ignition of protected areas.
Risk 2: Radiant Heat Damage
Cause:
Radiant heat from welding arcs and hot metal surfaces.
Risk:
Heat damage to cables, hoses, machinery, and structural components.
Protection Provided:
The fiberglass core reflects and dissipates radiant heat, reducing heat transfer to protected objects.
Risk 3: Mechanical Wear During Use
Cause:
Frequent dragging, folding, and repositioning of blankets in industrial environments.
Risk:
Premature fabric wear and reduced service life.
Protection Provided:
The vermiculite coating enhances surface durability and abrasion resistance.

-
Not designed for continuous thermal insulation
-
Not suitable for use as a personal protective garment
For extreme heat or flame exposure, specialized fire-resistant textiles should be considered.
Frequently Asked Questions (FAQ)
Is this welding blanket fireproof?
The blanket is fire-resistant and designed to protect against welding sparks, spatter, and radiant heat, but it is not completely fireproof.
Can it be reused?
Yes. With proper handling, the blanket can be reused multiple times depending on exposure conditions.
Is the vermiculite coating safe?
Yes. Vermiculite coating is widely used in industrial welding blankets to improve heat resistance and durability.
Are custom sizes available?
Yes. Custom dimensions, thicknesses, and packaging options are available.
Engineering Recommendation
For welding and hot work operations where sparks, molten metal, and radiant heat pose a fire risk, the use of a Vermiculite Coated Fiberglass Welding Blanket is recommended as an effective and practical protective solution.
