Glass Wool Board Pipe Roll
Glass Wool Board Pipe Roll (commonly known as Fiberglass) is a lightweight, non-combustible thermal and acoustic insulation material made from spinning molten glass into fine fibers. These fibers are then bound together with a resin binder and manufactured into various densities and forms (rolls, boards, pipe covers). Glass Wool is primarily used for low to medium-temperature insulation where cost-effectiveness, fire resistance, and superior acoustic performance are major considerations.
Main Composition
The material is predominantly amorphous SiO2 (Silicon Dioxide, glass) with small amounts of fluxing agents, binders, and oils.
| CATEGORY | COMPOSITION | TYPICAL MST (Continuous) | PRIMARY APPLICATION FOCUS |
| Fiberglass | SiO2 | 230°C to 450°C (450 F to 850 F) | Low to medium T thermal insulation and noise reduction. |
Key Forms and Use
| PRODUCT FORM | CONSTRUCTION | PRIMARY APPLICATION |
| Roll/Batt | Flexible blanket, often faced with foil or paper | Wall cavities, roof/ceiling insulation, ducts (low-density). |
| Board | Semi-rigid or rigid panel | HVAC duct lining, external wall sheathing, acoustic panels (medium/high-density). |
| Pipe | Pre-formed cylindrical sections (two halves) | Low-pressure steam, hot/cold water, and process piping. |

Advantages and Key Characteristics
Glass Wool is the most widely used insulation material globally, valued for its versatility and balance of performance and cost.
- Excellent Thermal Performance (k): The fine fibers trap a large volume of air, providing a low thermal conductivity that efficiently reduces heat transfer in low to medium-temperature ranges.
- Acoustic Absorption: The open-cell, fibrous structure is highly effective at absorbing sound energy (noise reduction), making it invaluable in HVAC systems, offices, and industrial buildings.
- Non-Combustible: The glass fibers themselves will not burn, although the binder may smoke or char at lower temperatures (~230°C). It is a highly fire-safe material.
- Cost-Effective: It is generally the lowest-cost option for insulating large areas and is available in forms suitable for standard construction methods.
Typical Industries and Applications
Glass wool is the insulation staple in most commercial and residential sectors:
- Commercial/Residential Building: Rolls/Batts are used in walls, floors, and attics for thermal and sound insulation.
- HVAC Systems: Boards are used to line the interior of air ducts for thermal insulation and noise suppression, or on the exterior of sheet metal ducts.
- Process Piping: Pipe covers are used to insulate cold water lines (to prevent condensation and freezing) and hot lines (up to 450°C) in industrial and commercial plumbing systems.
- OEM Equipment: Used as interior lining for ovens, dryers, and commercial appliances.
Key Data Sheet Properties to Consider
Selection is based on density, temperature, and facing:
- Maximum Service Temperature (MST): CRITICAL VALUE. Must not be exceeded, as the resin binder will degrade and the insulation performance will diminish.
- Density: Higher density boards provide better structural integrity and acoustic absorption but higher cost. Lower density rolls are more flexible and common in walls.
- Facing: Foil-scrim-kraft (FSK) facings are common for rolls and pipe covers to act as a vapor barrier and provide a smooth, durable exterior surface.
Technical Guidance: When used in high-humidity or cold-side applications (e.g., cold water pipes), the vapor barrier (facing) must be installed correctly and continuously sealed to prevent moisture migration into the insulation, which would compromise the thermal performance and risk Corrosion Under Insulation (CUI).

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
Q: Where are the Rabatec refractories and materials produced? | A: Our products are primarily sourced from specialized manufacturing plants in China. Crucially, these facilities have all undergone rigorous audits and achieved comprehensive ISO certifications (Quality, Environment, and Safety), ensuring that production adheres to the highest global standards for consistency and performance. |
Q: What refractory materials does the company offer? | A: We supply a comprehensive portfolio of advanced refractory solutions, including: Shaped Products: Alumina & Silica Bricks, Basic & Specialized Bricks (e.g., Magnesia), SiC & Structural Ceramics, and Precast Shapes. Monolithic Products: Refractory Castables, Mixes & Mortars. Insulation: Insulation Fibre and High-Performance Insulation Products. |
Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
