Sustainability

Relying on entrapped air for its thermal properties, Rockwool insulation does not contain (and has nevercontained) gases that have Ozone Depleting Potential (ODP) or Global Warming Potential (GWP). Rockwool therefore complies with the relatively modest threshold of GWP<5 included in documents such as the Code for Sustainable Homes.

Rockwool Ltd is increasingly involved in recycling waste Rockwool material that may be generated during installation or at end of life disposal, and has a recycling scheme that is recognised by WRAP andthe Environment Agency.
We are happy to discuss the individual requirementsof contractors and users considering returningRockwool materials to our factory for recycling.

Fireproofing

RockPrime blown loft insulation achieves an A1 classification in accordance with BS EN 13501-1 and is therefore non-combustible as defined in UK and Ireland building regulations.

Soundproofing

Insulation can improve the acoustic performance, i.e. soundproofing, of a building. 250mm of Rockwool Blown Loft Insulation, with an isolated 12.5mm plasterboard ceiling, achieved > 50dB reduction in a tiled roof construction.

A typical tiled roof construction incorporating a plasterboard ceiling and insulated with RockPrime should achieve and airbourne sound reduction of approximately 31dB.

Durability

Blown Loft Insulation is a durable material. When installed it will not be affected by normal ventilation within the loft space and will remain an effective insulant for the lifetime of the building.

Because of its density, Blown Loft Insulation will not suffer from wind displacement via air movement. Blown Loft Insulation is a completely inert, rot-proof material and does not encourage the growth of fungi, moulds and bacteria or offer sustenance to vermin.

Compatibility

Rockwool will not react with any metal components in the loft, nor will it cause loss of plasticiser from PVC cables and pipes.
