Knauf Insulation - Loft Roll 44 - 150mm

The R-value depends on the thickness and installation method. For 150mm, the U-value is approximately 0.24 W/m²K when installed correctly in a pitched roof, which corresponds to a significant R-value. Exact R-values can be calculated based on the thermal conductivity (0.044 W/mK) and the thickness.

This specific product, Loft Roll 44, is primarily designed for pitched roofs at ceiling level and floors. While it provides thermal insulation, specialized products are typically recommended for external wall applications to meet specific performance and building code requirements.

'A1 non-combustible' is the highest European classification for fire performance. It means the material does not contribute to fire in any way and is considered virtually non-combustible.

Knauf Insulation sometimes partners with other manufacturers like Isover and Superglass to ensure product availability. These rolls are guaranteed to be of the same specification, quality, and price point as the Knauf product.

Store the rolls upright in a dry, well-ventilated area, protected from moisture and direct sunlight. Avoid stacking too many rolls high to prevent excessive compression.

While primarily a thermal insulator, mineral wool products do offer some acoustic absorption benefits due to their density and fibrous structure, helping to reduce sound transmission.

ECOSE Technology is a binder technology used by Knauf Insulation that replaces traditional petroleum-based binders with a plant-based, renewable alternative. This results in a softer, more comfortable product to handle and reduces dust compared to older mineral wools.

Although ECOSE Technology makes the fibers softer, wearing gloves, long sleeves, eye protection, and a dust mask is still recommended during handling and installation to prevent skin and respiratory irritation.

Ensure precise cuts are made to fit snugly between joists or rafters. Avoid compressing the insulation, as this reduces its thermal performance. Check for and fill any gaps with small pieces of insulation.

Use a sharp utility knife or a dedicated insulation saw. Cutting along the pre-defined perforations will facilitate straighter and easier cuts.

Ensure the area was dry before installation and that there are no sources of moisture ingress. Proper ventilation in roof spaces is crucial to prevent condensation. The insulation itself should be kept dry during storage and installation.
