Glass Wool Strip

Glass Wool Strip is a professional strip-shaped thermal insulation and sound-absorbing material processed by precision slitting of high-quality glass wool boards/blankets, manufactured through molten glass centrifugal fiber forming, thermosetting resin spraying, thermal curing and special slitting molding processes. With a regular strip structure and adjustable width, thickness and density, it is tailor-made for the insulation and sound insulation needs of special parts such as pipeline wrapping, building partition joints and equipment gap filling. The product inherits all the excellent core properties of glass wool materials, including Grade A non-combustibility, low thermal conductivity, high hydrophobicity and stable chemical performance, and features easy cutting, close fitting and convenient construction. It is a key matching material for pipeline insulation engineering and building partition construction, which can effectively fill the gap of special construction parts, ensure the integrity of the insulation and sound insulation system, and is widely used in chemical, electric power, construction and HVAC fields, fully meeting the high-standard requirements of engineering for the insulation of special-shaped and small-size parts.

Core Performance Features

High-Efficiency Thermal Insulation & Sealing

It has a low thermal conductivity coefficient of 0.034-0.050 W/(m·K), and the dense fibrous structure forms a closed thermal insulation layer, which can effectively block heat conduction and convection in narrow gaps and pipeline wrapping parts. It makes up for the insulation blank of ordinary glass wool products in special parts, ensures the overall thermal insulation effect of the engineering system, and reduces energy loss of pipelines and buildings.

Grade A Non-Combustible Fire Resistance

As an inorganic non-combustible glass wool material, it meets the Grade A (A1) non-combustible standard for building insulation materials. It will not burn or spread fire when exposed to high temperature or fire, can effectively block the spread of fire along pipeline gaps and building partition joints, and does not release toxic smoke at high temperature, providing reliable fire safety protection for the whole engineering system.

Excellent Hydrophobic & Moisture-Resistant Performance

With a hydrophobic rate of up to 90% (far exceeding the national standard of ≥98.0%) and a mass moisture absorption rate of only 2.0% (better than the standard requirement of ≤5.0%), it can effectively prevent liquid water and water vapor from penetrating into the material. It can maintain stable insulation performance in humid environments such as underground pipelines, building outer walls and equipment basements, and avoid performance degradation caused by water absorption.

Outstanding Sound Insulation & Noise Reduction

The fine and disorderly glass fiber structure can effectively absorb the noise transmitted through gaps and pipeline vibrations, reduce the spread of air-borne and solid-borne noise, and optimize the acoustic environment of industrial workshops and building interiors. It is especially suitable for the sound insulation treatment of building partition joints and industrial pipeline wrapping parts.

Stable Physical & Chemical Properties

It has good chemical stability and is not easy to react with acids, alkalis, oil and other chemical media, with excellent corrosion and aging resistance; it has appropriate structural strength and toughness, is not easy to crack or break during construction and use, and can adapt to the thermal expansion and contraction of pipelines and buildings, ensuring long-term stable use.

Environmental Protection & Health Safety

The product does not contain formaldehyde, asbestos, acrylic and other harmful substances, no harmful gas is released during production, construction and long-term use, complying with national green building material standards and indoor air quality requirements, and is harmless to construction personnel and the use environment.

Main Application Fields

Industrial Pipeline Wrapping & Insulation

Widely used for the insulation and wrapping of various industrial pipelines such as chemical, electric power and metallurgy, especially for the insulation treatment of pipeline elbows, tees, flanges and other special-shaped parts, as well as the gap filling between pipeline brackets and pipelines, ensuring the integrity of the pipeline insulation layer.

Building Partition & Joint Sealing

Applied to the gap filling and sound insulation treatment of building interior partitions, outer wall joints, floor interlayers and ceiling gaps, it can effectively block the heat and noise transmission through gaps, improve the overall thermal insulation and sound insulation effect of buildings, and is an important auxiliary material for green building construction.

HVAC System Matching Insulation

Used for the gap filling of central air conditioning duct joints, fan coil brackets and pipeline connection parts, it makes up for the insulation blank of the air conditioning system's small parts, reduces the cold and heat loss of the air conditioning system, and improves the overall energy efficiency of the system.

Equipment Gap Filling & Insulation

Suitable for the insulation and sealing of gaps between industrial equipment components, mechanical equipment basements and metal structural joints, it can reduce the heat loss of equipment and the spread of mechanical noise, and improve the operating efficiency and working environment of the equipment.

Product Specifications & Customization Advantages

The product supports full specification customization according to engineering needs, and the conventional customizable parameters are matched with glass wool boards/blankets, with the following core specifications (special sizes can be customized as required):

Length: Customizable according to construction needs (1000~2400mm is common)

Width: 50~500mm (precision slitting, adjustable according to gap size)

Thickness: 20~100mm (consistent with the thickness of glass wool board raw materials)

Density: 24~96kg/m³ (selectable according to insulation and strength requirements)

Construction & Application Advantages

Precise Fitting & Easy Construction

With a regular strip structure, it can be perfectly fitted with the gap size of pipelines, buildings and equipment, avoiding the problem of poor sealing of irregular materials; it can be arbitrarily cut and spliced on site without special construction equipment, and the construction process is simple and efficient.

Good Toughness & No Cracking

It has no stress corrosion, and will not break within 1 minute during cutting and installation; the low short-term water absorption (1.3kg/m²) ensures the material integrity during construction, and avoids performance damage caused by construction operation.

Strong Compatibility & Wide Adaptability

It can be used in combination with glass wool boards, pipes, blankets and other glass wool products, forming a complete insulation and sound insulation system; it is suitable for various construction environments such as dry, humid and high temperature, and can adapt to the use requirements of different fields and special parts.

Cost-Effective & Material Saving

Precision slitting forming ensures the full utilization of raw materials, avoids waste caused by on-site cutting of large-size glass wool boards; as an auxiliary matching material, it improves the overall use effect of the main insulation material, reduces the later energy consumption loss of the project, and has high comprehensive cost performance.
