The Thermal Blanket R3.7 Roof Insulation is a premium high-performance glasswool insulation solution designed to deliver exceptional thermal resistance and maximise energy efficiency in roofing systems. With a higher-density construction (22 kg/m³), it provides improved insulation performance and enhanced comfort in both hot and cold climates.
Dimensions: 130mm (Thickness) x 1.2m (Width)
Density: 22 kg/m³
Thermal Rating: R3.7
Application: Roof insulation / under metal roof systems
Material: Glasswool insulation blanket (foil or faced system depending on variant)
Thermal Performance: Provides very high thermal resistance, significantly reducing heat transfer through the roof structure. Helps minimise heat gain in summer and heat loss in winter for stable indoor temperatures year-round.
Energy Efficiency: Improves overall building energy performance by reducing reliance on heating and cooling systems, helping lower energy consumption and operating costs.
Installation: Supplied in roll format for efficient installation over roof trusses or battens. Flexible blanket design allows easy handling, cutting, and fitting to standard roof spacings for continuous coverage and minimal thermal bridging.
Sustainability: Typically manufactured using recycled glass content and environmentally responsible binder technology, supporting sustainable construction practices.
The Thermal Blanket R3.7 is suitable for residential, commercial, and light industrial roofing applications, especially under metal roofs. It is commonly used in homes, warehouses, and sheds where maximum thermal performance is required to improve comfort and reduce long-term energy costs.
