135mm Knauf Ceiling Rolls

The 135mm Knauf Insulation is a premium product within the Knauf Insulation range, offering superior thermal and acoustic properties. It’s made from high-quality glass mineral wool, known for its excellent performance characteristics.

The 135mm thickness is especially effective for applications requiring higher levels of thermal resistance, such as in colder climates or for buildings aiming for higher energy efficiency standards. This increased thickness provides enhanced insulation, ensuring buildings remain warm in the winter and cool in the summer, contributing to overall energy savings and comfort.

Benefits of 135mm Knauf

• Non-combustible
• High R-value
• High Density
• Lightweight quilt for ease of installation
• Economical packs for less storage and handling
• Manufactured with ECOSE® Technology

Thermal Conductivity

The thermal conductivity of Knauf Insulation 135mm is impressively low, typically around 0.037 W/mK, making it one of the more efficient options available. This low conductivity indicates that the material is highly effective at minimizing heat transfer, which is crucial for maintaining stable indoor temperatures. Installing this insulation can lead to significant reductions in heating and cooling costs, benefiting both the environment and the building’s occupants. It also complies with stringent building regulations and standards, ensuring its suitability for a wide range of construction and renovation projects.

Application

135mm Knauf Ceiling Rolls (Combi-cut) are primarily used for the thermal and acoustic insulation of pitched roofs at ceiling level. When used at ceiling level it is usually laid in one or two layers, with the first layer between the joists and the second layer over and at right angles to the joists.

Standards

Ceiling Rolls (Combi-cut) are manufactured in factories that are certified by Bureau Veritas to the following management system standards: EN 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems. These factories also produce materials compliant with the European product standard for insulation materials EN 13162.

Environmental

Ceiling Rolls (Combi-cut) represent no known threat to the environment and has zero Ozone Depletion Potential and zero Global Warming Potential.

Vapour resistivity

Ceiling Rolls (Combi-cut) offer negligible resistance to the passage of water vapour and has a vapour resistivity of 5.00MNs/g.m.

Handling and storage

Ceiling Roll is easy to handle and install, being lightweight and easy to separate into either 800 + 400mm or 2 x 600mm widths. The ceiling insulation is supplied in polythene packs which are designed for short term protection only. For longer-term protection on site, the product should be stored either indoors, or undercover and off the ground. The ceiling roll should not be left permanently exposed to the elements.
