Product type
Glass wool insulation is a lightweight, fibrous material made from recycled glass that is melted and spun into fine strands. It is designed to provide thermal insulation by trapping air within its structure, which helps to reduce heat transfer. This material is commonly used in residential and commercial buildings to improve energy efficiency and maintain comfortable indoor temperatures.
| Thermal conductivity | 0.030 to 0.045 W/m·K |
| Density | 10 to 100 kg/m³ |
| Thickness | 25 to 100 mm |
| Fire rating | Class A (non-combustible) |
| Sound absorption | NRC 0.75 to 1.00 |
When selecting glass wool insulation, consider the thermal conductivity rating to ensure optimal energy efficiency. It's also important to specify the desired thickness and density based on your project requirements. Check for fire ratings and any relevant certifications, especially for commercial applications. Providing the quantity needed will help suppliers give accurate quotes.
