Application

For the thermal insulation of cold pitched roofs at ceiling level. They are usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists.

Description

Glass mineral wool rolls, designed for use in

cold lofts where pitched roofs are insulated at ceiling level.


They are non-combustible with the best possible Euroclass A1 reaction to fire classification, and are manufactured using the manufacturer's exclusive bio-based binder, ECOSE® Technology.


Available in the following formats, giving a wide range of choice to suit specific installation requirements:

  • Combi-cut rolls
  • Ready-cut rolls
  • Uncut rolls
  • Short length, combi-cut rolls


Features and benefits:

  • Manufactured in two different options; long lengths to allow quick and simple installation maximizing efficiency, and shorter lengths for ease of handling on-site.
  • Combi-cut products are supplied partially perforated, providing the flexibility to be used between joists or used uncut as a full-width roll as a top-up layer, maximizing on-site efficiency.
  • Compression packed and lightweight for easy handling and moving around a site.
  • Awarded the DECLARE 'Red List Free' label which means it is free of any harmful chemicals listed on the Living Building Challenge (LBC) Red List.
  • A+ generic BRE Green Guide rating.
  • Easier to install correctly than other insulants such as rigid boards as they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
  • Durability: Odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.
  • Environmental: Contains no ozone-depleting substances or greenhouse gases. For further environmental information consult the relevant Environmental Product Declaration (EPD) on the manufacturer's website.


Available as partially cut rolls for use with:

  • Timber joists at 400 mm centres;
  • Timber joists at 600 mm centres;
  • Unsplit as a full width roll;
  • Partially cut, shorter length rolls;
  • Ready cut rolls for use between joists at 600 mm centres.


Standards and certification:

Manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management systems, as certified by TÜV Nord.

All of the manufacturer's glass mineral wool products have been awarded the DECLARE ‘Red List Free’ label. Having the ‘Red List Free’ label means that there are no ingredients in the product that are on the red list, including formaldehyde or phenol.
