What Is Fiberglass & Why It Matters

Fiberglass is a reinforced plastic made from extremely fine glass fibers that are woven or laid into mats, cloths, braids, or knitted forms. It combines lightweight strength, high temperature resistance, moisture/chemical resistance, and electrical insulation in one material.

Its core advantages include a high strength-to-weight ratio, corrosion and moisture resistance, non-conductivity, and flexibility in forming complex shapes.

These qualities make fiberglass the ideal choice for your projects, delivering reliable, long-lasting gasketing and insulation solutions designed around your specific needs

Ready to maximize performance and reliability with top-quality custom fiberglass solutions?

Engineered to Withstand Harsh Industrial Conditions

Your applications demand materials that perform under pressure. Our fiberglass products are built for continuous service in extreme environments, ensuring long-lasting reliability for your industry needs.

• Temperature Resistance — Continuous service up to 1000 °F (538 °C), with short-term exposure capabilities beyond this threshold depending on product form.
• Chemical Resistance — Unaffected by most common oils, solvents, and cleaning agents.
• Moisture Resistance — Maintains structural integrity even in humid or wet environments.
• Low Off-Gassing —Suitable for clean manufacturing and appliance applications.
• Availability— Tapes, ropes, tadpole tapes, paper, boards, and blankets are available in multiple densities, thicknesses, and widths for specific gasketing and insulation needs.

HVAC and Mechanical Systems: In heating, ventilation, and air conditioning systems, fiberglass is essential for thermal insulation and gasketing. Common products include: ManniGlass & Fiberglass Insulation, which provides thermal insulation for HVAC components to improve energy efficiency. Fiberglass Ropes and Tapes, which are essential for sealing and insulating ducting, boiler doors, and high-heat areas in HVAC systems.

Commercial Kitchens: High-output kitchens rely on appliances and equipment that generate extreme heat on a daily basis. Common products include: Fiberglass Paper which is lightweight, durable, and heat-resistant, ideal for use in high-temperature kitchen environments. Fiberglass Insulation is a versatile, reliable insulation material that ensures heat retention and energy efficiency. Fiberglass Ropes and Tapes, which provide secure gasketing and seals for ovens, fryers, and other equipment exposed to continuous thermal cycling.

Hearth, Stove, and Fireplace Manufacturing: Fiberglass has become the industry standard for gasketing and sealing in hearth products, including wood stoves, pellet stoves, and fireplaces. Common products include: Fiberglass Paper provides a lightweight, durable, and heat-resistant seal, ideal for various high-temperature insulation applications. Fiberglass Insulation is an industry-standard material for thermal protection, offering strong heat retention and energy efficiency. Fiberglass Mat is flexible and easy to install, providing excellent heat insulation in critical system areas. Fiberglass Ropes, Tapes and Tadpole Tapes offer high-temperature sealing solutions engineered to create secure gaskets, reliable barriers, and provide strong seals on uneven surfaces in demanding industrial and hearth applications.

Industrial and OEM Applications In large-scale industrial manufacturing, fiberglass is a go-to material for high-volume gasketing and insulation. From furnaces and kilns to heavy machinery and automotive systems, fiberglass products are custom-fabricated to precise specifications. Common products include: Fiberglass Blanket & Insulation are premium insulating materials built for high heat environments, delivering thermal protection and energy savings in heavy-duty industrial systems. Fiberglass Paper comes in lightweight, durable sheets that resist heat and flame, ideal for clean high-temperature installations and tight spaces. Fiberglass Tapes, Ropes & Tadpole Tapes are engineered to form tight, reliable seals, secure gasketing, and adaptive sealing around curves and joints in demanding industrial applications.
