Fiberglass Board Insulation for Industrial and Commercial Projects

Trusted Fiberglass Board Supplier for HVAC Duct & Building AcousticThermal Solutions

Xiaolong is a manufacturer of fiberglass board insulation built for commercial construction, ventilation systems, and industrial thermal-acoustic control. Fiberglass board insulation from Xiaolong solves this with a rigid, stable board that holds its shape, resists moisture, and delivers steady thermal and acoustic performance across a wide temperature range.

Every board is produced under controlled manufacturing conditions, so density, thickness, and thermal conductivity stay consistent from batch to batch. Project teams, contractors, and distributors work with Xiaolong because the product performs the same way on every job site and every order.

Notable Performance Benefits of Fiberglass Board Insulation

Reliable Thermal & Acoustic Performance

· Thermal conductivity of 0.034–0.038 W/(m·K) at 25°C keeps heat loss and heat gain low across HVAC ductwork and building envelopes.

· Dense fiber structure absorbs airborne sound, reducing noise transfer through mechanical rooms and partitions.

A1 Non-Combustible for Enhanced Fire Safety

· Made from inorganic fiberglass, so the board does not add fuel load to a structure.

· Suitable for use near mechanical equipment and in fire-rated assemblies where non-combustible materials are required.

Rigid Board with Excellent Dimensional Stability

· Holds a flat, straight profile after cutting and installation, with minimal sagging over time.

· Density range of 10–48 kg/m³ lets teams choose a firmer or lighter board depending on load and application.

Hydrophobic Anti-Mildew for Damp Environments

· Hydrophobic rate of ≥98% keeps moisture from soaking into the board, protecting R-value in humid or semi-exposed settings.

· Resists mold and mildew growth, which extends service life in coastal, tropical, or high-humidity projects.

Key Specifications

Practical Use-Cases of Fiberglass Board Insulation

Transit Infrastructure Auxiliary Zones

· Insulating ductwork and mechanical rooms in transit stations and depots.

· Acoustic damping in equipment rooms near platforms and public areas.

· Thermal lining for auxiliary buildings exposed to fluctuating outdoor temperatures.

Prefabricated Modular Unit Envelopes

· Wall and roof insulation for modular housing and portable buildings.

· Thermal cores for prefabricated cold storage or utility units.

· Fast-install boards that fit standard modular panel dimensions.

Semi-Exposed Shelter Structures

· Insulating equipment shelters, guard booths, and utility enclosures.

· Roof insulation for open-sided or semi-enclosed structures exposed to weather.

· Damp-resistant boards for shelters near coastal or high-humidity sites.

Building Retrofit & Renovation Projects

· Upgrading thermal performance in older commercial buildings without major structural changes.

· Replacing degraded or moisture-damaged insulation during envelope renovations.

· Adding acoustic control to renovated office, retail, or mixed-use spaces.

Frequently Asked Questions for Fiberglass Board Insulation

Does the board come with a facing, or is it available unfaced?

Both. Xiaolong offers unfaced boards as well as boards faced with aluminum foil or tissue paper, depending on your vapor barrier and finish requirements.

How is fiberglass board insulation packaged for shipping?

Boards are compressed into rolls for efficient shipping and storage, then expand to full thickness once unrolled and installed.

Is fiberglass board insulation resistant to moisture and mold?

Yes. With a hydrophobic rate of ≥98%, the board repels moisture rather than absorbing it, which helps prevent mold and mildew growth in damp or humid conditions.
