Installation

Apply the ROCKWOOL Acoustic Infill strips directlywithin the troughs of the metal deck. Ensure that alljoints are tightly butted together. Where lengths ofROCKWOOL Acoustic Infill require to be cut, this iseasily facilitated with a sharp knife.

Follow with the installation of the appropriate VCL,ROCKWOOL insulation and waterproofing layer inaccordance with the manufacturers’ requirements. Dayjoints must be formed at the conclusion of each sectionof work to seal exposed edges of the ROCKWOOLAcoustic Infill and HARDROCK DD roofing boards. Forroof board installation, see the HARDROCK® datasheet.

Design

The roof construction and design should comply with BS 6229:2003 (Code of practice for flat roofs withcontinuous supported coverings).

Vapour control layer

The need for a vapour control layer should be calculated in accordance with BS 5250: 2002 (Code of practice for control of condesation in buildings) and with reference to BS 6229: 2003 (Code of Practice for Flat Roofs with Continuously Supported Coverings).

Storage and handling

The need for a vapour control layer should be calculated in accordance with BS 5250: 2002 (Code of practice for control of condesation in buildings) and with reference to BS 6229: 2003 (Code of Practice for Flat Roofs with Continuously Supported Coverings).

All ROCKWOOL products provide outstanding thermalprotection as well as four added benefits:

Fire resistance

Acoustic comfort

Sustainable materials

Durability

Health and safety

The safety of ROCKWOOL stone wool is confirmed by current UK and Republic of Ireland health & safety regulations and EU directive 97/69/EC: ROCKWOOL stone wool fibres are not classified as a possible human carcinogen. A Material Safety Data Sheet is available and can be downloaded from www.rockwool.co.uk to assist in the preparation of risk assessments, as required by the Control of Substances Hazardous to Health Regulations (COSHH).

Environment

Made from a renewable and plentiful naturally occurring resource, ROCKWOOL insulation saves fuel costs and energy in use and relies on trapped air for its thermal properties.

ROCKWOOL insulation does not contain (and has never contained) gases that have ozone depletion potential (ODP) or global warming potential (GWP).

ROCKWOOL stone wool insulation is approximately 97% recyclable. For waste ROCKWOOL material that may be generated during installation or at end of life, we are happy to discuss the individual requirements of contractors and users considering returning these materials to our factory for recycling.
