Core Advantages of Xiaolong Fiberglass Blanket Insulation

Combined Thermal-Acoustic Performance

· Low thermal conductivity limits heat transfer through walls, roofs, and ductwork while reducing airborne noise.

· Consistent fiber structure keeps performance stable across the full thickness and density range.

A1 Non-Combustible With No Toxic Fumes at High Temperatures

· Classified as non-combustible material, supporting fire-safety requirements in commercial and industrial buildings.

· Does not release toxic smoke when exposed to high heat, protecting occupants during a fire event.

Compressible Roll With High Resilience for Complex Surfaces

· Compresses for compact shipping and storage, then recovers its full thickness after installation.

· Flexes around pipes, ducts, and irregular surfaces without tearing or losing shape.

Hydrophobic and Mildew-Resistant for Damp Environments

· Repels moisture so insulating value is preserved in humid or wet-prone conditions.

· Resists mold and mildew growth, supporting a cleaner, healthier building envelope over time.

Key Specifications

Application Fields for Fiberglass Blanket Insulation

Commercial & Public Building Thermal-Acoustic Insulation

· Wall and roof cavities in offices, shopping centers, and public facilities.

· Interior partitions where both heat control and noise reduction are required.

Industrial Equipment & Vessel Insulation

· Wrapping for tanks, boilers, and pressure vessels operating at elevated temperatures.

· Pipe and vessel jacketing to reduce heat loss and protect personnel from hot surfaces.

HVAC Duct and Air-Handling System Projects

· External wrap insulation for sheet-metal ductwork to prevent condensation and heat loss.

· Internal duct liner applications where sound attenuation is also needed.

Steel Structure Workshop Envelope Insulation

· Roof and wall insulation layers under metal cladding in factories and warehouses.

· Reduces indoor temperature swings caused by direct sun exposure on steel roofing.

Mechanical Room & Noise-Reduction Works

· Acoustic lining for plant rooms housing pumps, generators, and compressors.

· Insulation around mechanical equipment to dampen operational noise transfer to adjacent spaces.

Common Buyer Questions for Fiberglass Blanket Insulation Rolls

1. What is the difference between faced and unfaced fiberglass blanket insulation?

Faced insulation includes a layer such as aluminum foil or tissue paper, which adds a vapor barrier or reflective surface. Unfaced insulation is used when a separate vapor barrier is installed or when facing isn't required by the application.

3. What temperature range can this insulation withstand?

It is rated for continuous operation from -20℃ to 350℃, which covers most building, HVAC, and industrial process applications.

4. How is fiberglass blanket insulation packaged for shipping?

Rolls are compressed for packing, which reduces shipping volume, then expand back to full thickness once unrolled at the job site.

5. Is this insulation suitable for humid or coastal climates?

Yes. The hydrophobic treatment resists moisture absorption, helping maintain insulating performance in damp or humid environments.
