Knauf Earth Wool Roll Insulation

The 150mm Loft Roll itself is made of Knauf’s Earth Wool material. The roll has excellent thermal qualities and is constructed of low-density glass mineral wool. Without the use of CFCs or HCFCs, Knauf Loft Roll is favourable for the environment because it does not have the capacity to deplete the ozone layer and has little to no ability to contribute to global warming. Since Earth Wool insulation can trap heat, it reduces the amount of energy needed to keep a structure warm. It also aids in reducing the building’s carbon footprint.

In order to create the Loft Roll, Knauf uses revolutionary ECOSE® Technology together with a distinctive bio-based binder. Furthermore, the notion that this binder contains no extra phenol or formaldehyde suggests that the lower dust levels are far less frequent.

Additionally, ECOSE® technology from Knauf uses up to 70% less energy than traditional binders, allowing it to be one of the more ecologically friendly products.

Knauf Loft Roll Manufacturing Process

Knauf 150mm Loft Roll is now more manageable than ever due to the production technologies employed throughout the design phase. Despite the fact that customers regularly remark on how soft the product feels to the touch, we nevertheless suggest wearing the appropriate PPE when handling any kind of loft roll because it may cause skin irritation.

Traditionally, handling glass wool materials like loft roll has the potential to injure or scratch your skin. Due to new industrial production techniques that have arisen in recent years, the product is now categorised as minimal itch. It is still advised to handle mineral wool with care to prevent agitating yourself or other people. Use a crawl board to navigate a loft safely and use caution when doing this.
