Insulated glass wool roll felt is a versatile material designed for thermal and acoustic insulation purposes in various construction and industrial applications. Composed primarily of glass fibers, this material is engineered to offer excellent thermal resistance, sound absorption properties, and fire-retardant characteristics. Here's a detailed specification of insulated glass wool roll felt:
1. Composition:
Main Material: Glass fibers derived from recycled glass, silica sand, limestone, and soda ash.
Binder: Thermosetting resin (usually phenolic resin) for cohesion and stability.
2. Thermal Insulation Properties:
Thermal Conductivity: Typically ranging from 0.030 to 0.045 W/mK, depending on density and thickness.
Thermal Resistance (R-value): Varied, but commonly ranges from R-3.5 to R-4.3 per inch of thickness.
3. Acoustic Insulation Properties:
Sound Absorption Coefficient: High sound absorption capacity across a broad range of frequencies.
Noise Reduction Coefficient (NRC): Typically ranging from 0.75 to 0.95, indicating excellent sound absorption.
4. Density and Thickness:
Density: Usually ranges from 10 kg/m3 to 48 kg/m3, with higher densities offering better insulation properties.
Thickness: Available in various thicknesses, commonly ranging from 25mm to 100mm or more.
5. Dimensions and Packaging:
Roll Width: Typically available in widths ranging from 600mm to 1200mm.
Roll Length: Can vary, often supplied in lengths of 5 meters to 30 meters.
Packaging: Rolls are compressed and packed in polyethylene or polypropylene packaging for easy transportation and handling.
6. Fire Performance:
Fire Rating: Classified as non-combustible or fire-resistant (Class A1 or A2) according to relevant standards (e.g., ASTM E84, EN 13501).
Melting Point: Glass wool fibers melt at high temperatures, reducing fire spread and heat transfer.
7. Environmental and Safety Considerations:
Environmental Impact: Typically contains recycled materials and is itself recyclable.
Health and Safety: Generally safe to handle, but wearing appropriate protective equipment (e.g., gloves, masks) during installation is recommended due to potential irritation from glass fibers.
8. Applications:
Residential: Insulation for walls, roofs, attics, floors, and HVAC ducts in homes and apartments.
Commercial/Industrial: Thermal and acoustic insulation for offices, factories, warehouses, and industrial facilities.
HVAC Systems: Insulating air ducts, pipes, and equipment to improve energy efficiency and reduce noise transmission.
Marine and Automotive: Insulation for ships, boats, automobiles, and trains to enhance comfort and safety.
9. Installation:
Typically installed between framing members or over existing surfaces using staples, adhesive, or mechanical fasteners.
Installation should follow manufacturer's guidelines and local building codes to ensure proper performance and safety.
10. Maintenance:
Requires minimal maintenance once installed properly.
Should not be exposed to excessive moisture to prevent degradation of insulation properties.
In summary, insulated glass wool roll felt is a high-performance insulation material offering excellent thermal and acoustic properties, fire resistance, and environmental sustainability. Its versatility makes it suitable for a wide range of applications in residential, commercial, industrial, marine, and automotive settings, providing energy efficiency, comfort, and safety benefits.
