Its flexible woven structure allows it to be wrapped tightly around pipes for stress relieving, draped over freshly welded castings for controlled cooling, or placed over sensitive equipment to protect against radiant heat. The un-coated fiberglass excels at trapping air and resisting thermal transfer, making it ideal for applications where heat retention is as important as heat protection. In stress-relieving operations, the Insul-Shield blanket's thermal insulation properties ensure that metal components cool slowly and uniformly, reducing residual stress and preventing warping or cracking. This controlled cooling capability is essential for high-precision manufacturing and aerospace applications. Vertical Thermal Curtains (Hanging) Equipped with brass grommets every 24 inches, this blanket can also be suspended vertically to create thermal barriers. While it can serve as a welding curtain for spark protection, its true value in vertical applications is isolating heat-generating equipment (like furnaces or large welding operations) from adjacent work areas, protecting personnel from radiant heat exposure. The vertical deployment capability makes the 24 oz. Insul-Shield ideal for creating temporary or permanent thermal zones in manufacturing facilities, protecting nearby equipment and personnel from high-temperature operations.

Insul-Shield vs. Coated Welding Blankets Understanding the differences between un-coated and coated welding blankets is essential for selecting the right thermal protection solution for your application: Un-Coated Insul-Shield (24 oz.) Superior thermal insulation and heat retention Ideal for stress relieving and controlled cooling applications Minimal smoke and outgassing due to heat treatment Excellent for wrapping and draping applications Lower cost per unit Best for heat management rather than spark protection Coated Welding Blankets (Silicone, Neoprene, Acrylic) Superior spark and spatter protection Better fluid resistance (oil, coolant, water) Easier to clean and maintain Better for heavy welding and cutting operations Higher cost Reduced thermal insulation capacity The Bottom Line: If your primary need is thermal insulation and heat management, the 24 oz. Insul-Shield is the superior choice. If you need maximum spark and spatter protection with fluid resistance, a coated blanket may be more appropriate. Many facilities use both types in different areas of their operations. Frequently Asked Questions (FAQ) What is the difference between Insul-Shield and coated welding blankets? Coated blankets (like silicone, neoprene, or acrylic) are designed primarily to shed sparks, slag, and fluids. The Insul-Shield is un-coated, heat-treated fiberglass designed specifically for thermal insulation and heat retention. It is better at trapping heat for stress relieving, while coated blankets are better for heavy spatter protection. Can the 24 oz. Insul-Shield be used for stress relieving? Yes, this is one of its primary applications. The 24 oz. weight provides excellent thermal insulation, allowing it to be wrapped around pipes or draped over welds to ensure a slow, controlled cooling process, which is critical for stress relieving and preventing residual stress in metal components. Does this blanket produce smoke when heated? Because the Insul-Shield fiberglass is heat-treated during manufacturing to remove sizing and organic binders, it produces significantly less smoke and outgassing compared to standard, non-treated fiberglass when exposed to high temperatures. This makes it ideal for indoor applications where air quality is a concern. Is the 24 oz. Insul-Shield itchy to handle? Like all un-coated fiberglass products, it can cause skin irritation. We strongly recommend wearing gloves, long sleeves, and appropriate PPE when handling, installing, or removing the blanket. Proper protective equipment ensures safe handling and prevents irritation. Can I cut this blanket to a custom size myself? While it can be cut, we do not recommend it because the woven fiberglass edges will fray and unravel quickly without a properly sewn hem. We offer 21 standard sizes, and if you need a specific dimension, DeBrovys provides custom fabrication services to ensure the edges are properly finished and grommeted. What is the maximum continuous temperature rating? The 24 oz. Insul-Shield has a continuous temperature rating of 1000°F (537°C) and an intermittent rating of 1500°F (815°C). These ratings ensure reliable performance in demanding thermal applications while maintaining structural integrity. Are the grommets rust-resistant? Yes, the grommets are made from heavy-duty brass, which is naturally rust-resistant and corrosion-resistant. This ensures the grommets will maintain their functionality and appearance even in harsh industrial environments or outdoor applications. Can I use the Insul-Shield for outdoor applications? Yes, the 24 oz. Insul-Shield can be used outdoors. The brass grommets are corrosion-resistant, and the heat-treated fiberglass is durable and weather-resistant. However, prolonged UV exposure may gradually affect the fiberglass, so we recommend covering the blanket when not in use for extended outdoor storage.
