Best Heat-Resistant Fabrics for Industrial Applications

In today’s industrial environments, heat is more than an inconvenience; it’s a serious hazard. From power generation, to industrial processing plants, to shipbuilding and construction, to metal casting foundries and more, workers and equipment are regularly exposed to high temperatures that can reach thousands of degrees. Without proper protection, extreme heat can damage machinery, reduce efficiency, and pose a risk to lives.

That’s where heat-resistant insulation fabrics come in. These specialized materials are engineered to withstand both flames, sparks, molten metal splashes, and radiant energy from the exterior, while also being used to retain and hold heat and energy within designated operating systems. Though exposed to extreme conditions, these fabrics, tapes, and other materials maintain durability and flexibility.

They are the foundation of well-designed machine and piping insulation systems.  The critical element of fire and smoke barriers, curtains, and industrial heat shields.  And used to protect people in specialized PPE during hazardous work 

In this guide, we’ll break down the types of high-temperature fabrics for industrial applications offered by Newtex Industries, explore their key properties, and highlight where they are most effective.

Why Heat-Resistant Fabrics Matter in Industrial Applications?

Texturized fiberglass heat-resistant insulation fabrics are critical in industry because they serve as the frontline defense against workplace hazards that ordinary textiles cannot withstand. In high-temperature environments, they:

1) Protect workers from life-threatening risks such as flames, sparks, molten metal splashes, and radiant heat.

2) Ensure operational safety by preventing fire spread through smoke curtains, fire blankets, and insulation systems.

3) Extend equipment life by shielding machinery from thermal damage and reducing costly downtime.

4) Improve efficiency by minimizing heat loss with thermal insulation fabric materials.

5) Support compliance with strict safety regulations such as NFPA, ISO, and ASTM standards.

In short, these fabrics matter because they safeguard people, property, and productivity in high-temperature environments.

Key Properties of Heat-Resistant Fabrics

When engineers and safety managers evaluate fabrics for industrial use, they look for a balance of properties:

  • High temperature resistance (conductive, convective, and radiant exposure).

  • Non-flammable and fire-retardant to prevent ignition and flame spread.

  • Texturized with entrapped air to provide thermal insulation and reduce heat transfer.

  • Durability against abrasion, flexing, and vibration.

  • Chemical resistance to oils, molten splash, and industrial contaminants.

  • Flexibility for fabrication into apparel or barriers.

The best thermal insulation fabric materials combine these qualities to protect both people and processes.

5 Types of High-Temperature Fabrics Offered By Newtex Industries

Industrial operations push materials to their limits. From molten metal processing to automotive heat shielding and marine fire protection, fabrics must deliver safety, reliability, and performance where ordinary textiles fail.

Newtex Industries has built a portfolio of specialized high-temperature fabrics to meet these challenges. These solutions are trusted worldwide in industries including smelting, automotive manufacturing, power generation, and marine safety.

We offer five distinct categories of high-performance fabrics, each designed to deliver reliable protection and superior performance in demanding industrial environments:

1. High Temperature Safety Apparel Fabrics

When workers are exposed to direct flame, molten metal, or radiant energy, these high-temperature heat & fire-retardant fabrics can provide reliable protection.

A. Aluminized Fabrics (Z-Flex® II, DualMirror® II): Designed for proximity firefighting and foundry operations, these fabrics use advanced aluminization technology to reflect up to 95% of radiant heat. The reflective surface keeps core body temperatures safer while protecting against sparks and molten splashes.

B. Zetex® & ZetexPlus® Glass Fabrics: These highly texturized fiberglass fabrics excel in heat contact applications such as gloves and mitts. Workers handling hot molds, glass, or tools rely on them for insulation up to 2000°F.

These fabrics are widely certified to meet NFPA, ISO, and ASTM standards, making them trusted choices for PPE designers worldwide.

Applications:

  • Firefighting suits

  • Foundry jackets and aprons

  • Welding apparel

  • High-temp gloves and mitts

2. Insulation Fabrics

In addition to apparel, thermal insulation fabrics are essential for controlling heat in industrial systems. They reduce energy loss, maintain process efficiency, and shield personnel from burn hazards.

A. Zetex® & ZetexPlus® Fiberglass: Used as insulation wraps, pads, and jackets, these fabrics maintain strength even at continuous high temperatures.

B. Silica and OPAN Felt Mats: Designed for intensive insulation applications in furnaces, turbines, and piping systems.

C. Coated Fabrics (Z-Tuff™ Silicone & PTFE): Provide durable weather and chemical resistance for exterior applications.

By combining insulation fabric with coatings and laminates, Newtex delivers solutions that resist abrasion, moisture, and environmental stress while maintaining heat resistance.

Applications:

  • Removable insulation blankets

  • Furnace and turbine insulation

  • Heat containment covers

  • Pipe and valve wraps

3. Radiant Heat Shield Fabrics

Industrial and automotive environments often require heat shield fabric that reflects radiant energy while withstanding vibration and flexing.

A. Z-Flex® II Multilayer Aluminized Fabrics: Feature a proprietary vacuum-deposited aluminum film that bonds flexibly with fiberglass or aramid substrates. Unlike standard foil laminates, these fabrics resist cracking and delamination under movement.

B. DualMirror® II Aluminized Fabrics: Provide excellent radiant heat protection and durability, ideal for protective clothing and industrial heat shields.

C. Z-Flex® AF Foil Fabrics: A cost-effective option for static heat barriers where flexibility is less critical.

Applications:

  • Automotive exhaust and engine shields

  • Industrial heat shields for machinery

  • Proximity protective apparel

  • High-vibration shielding in aerospace and manufacturing

4. Fire & Smoke Control Fabrics

Managing fire hazards isn’t limited to withstanding heat. Fabrics designed for smoke control and flame containment play an equally vital role in industrial safety, ensuring both people and infrastructure remain protected.

A. Z-Block® FS Fabrics: Lightweight yet strong polyurethane-coated textiles designed for smoke curtains in commercial and industrial buildings.

B. ZetexPlus® Fire Curtains: Used in theaters and performance halls to provide fire barriers that drop automatically during emergencies.

C. Z-Shield® Marine Hullboard: Provides both fire resistance and insulation for marine interiors, ensuring safety without compromising comfort.

Applications:

  • Automated smoke curtains

  • Fire containment covers (FCCs)

  • Marine fire protection systems

  • Theatrical stage fire curtains

5. Welding Fabrics

Few environments are as demanding as welding, where sparks, spatter, and intense radiant heat are constant. Welding fabrics must resist not only flames but also molten metal droplets.

A. Z-Shield™ and ZetexPlus® Fabrics: Available in multiple colors and styles for welding blankets, curtains, and drapes. They protect both workers and nearby equipment from sparks and heat damage.

B. High-Visibility Drapes (available in Bulldog Red and Salmon colors): Improve safety by clearly marking welding zones while offering superior flame resistance.

Applications:

  • Welding blankets and pads

  • Heat- and spark-resistant curtains

  • Machine protection covers

  • Hot work isolation barriers
