Slabs

Manufactured from renewable volcanic rock, this 50mm thick ROCKWOOL Flexi Slab acoustic insulation has a total coverage of 8.64m². Fire resistant, innovative and flexi-edged it is designed to reduce your building's carbon footprint, this product provides both thermal insulation and acoustic performance.

Made with patented technology and one flexible edge, this insulation slab is a quick and seamless fit between timber and metal frame systems in walls, floors, roofs and partitions. There is no need to cut the multi-use slab which reduces waste, and minimal maintenance is required.

• 50mm x 1200mm x 600mm.
• 8.64m² pack coverage.
• 0.038 W/mK thermal conductivity.
• 12 slabs per pack.
• Easy to cut to any shape with a sharp knife if necessary.
• Low in maintenance.
• Tight and secure fit.
• Versatile across applications, including walls, floors, roofs and partitions.
• Flexi-edged and fire resistant.
• A1 classification to BS EN 13501-1.

ROCKWOOL stone wool products achieve noise reduction through: impeding the sound transmission in an element of the structure, and absorbing the sound into the surface due to the structured fibres. They are great absorbers with characteristically high coefficients across a large frequency range.

Knauf DriTherm Cavity Slabs are semi-rigid and rigid glass mineral wool slabs well-known for their water-repellent and non-combustible qualities. They are excellent for conventional upright wall tie spacings, ensuring a secure joint with adjoining slabs.

Suitable for structures up to 12m high in any exposure zone and multi-storey uses up to 25m. As a pro tip, remember that tightly knitting the slabs together eliminates air gaps within the neighbouring slabs ensuring stronger and better insulation.

DriTherm Cavity 37 Slabs pose no threat to the environment and contribute zero Ozone Depletion Potential (ODP) and have a low Global Warming Potential. Knauf Insulation mineral wool is created by making use of a bio-based and innovative formaldehyde-free binder technology. The raw materials for these Knauf Insulation cavity slabs are renewable materials, rather than petroleum-based compounds. The glass mineral wool water-repellent insulation slabs pass on higher environmental sustainability making them extremely eco-friendly.

FEATURES

• Premium glass mineral wool
• Sturdy slabs
• Sold in pallets
• Fire-safe
• Water-repellent
• Scent-free, rot proof
• Eco-friendly insulation
• Water-vapour resistant: No

STORAGE

For a continued protection on-site, store the Knauf slabs indoors. Keep them covered by a weatherproof tarpaulin and off the ground. Do not leave the pallets outdoors, permanently exposed to the elements.

CERTIFICATIONS

Knauf DriTherm Cavity Slabs 37 are produced as per BS EN 13162, EN 16001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as approved by Bureau Veritas.
