Application

Designed for use as thermal sheathing insulation in rainscreen facade systems either below and above 18 m in height.

Recommended for use in rainscreen facade systems using a timber, SFS, masonry or reinforced concrete substrate. Also recommended for use in partial fill applications, behind a steel or timber frame with a masonry outer facade.

Description

Rocksilk® RainScreen Slab is a BBA-certified rock mineral wool slab designed for use as sheathing insulation in rainscreen facade systems both below and above 18 m in height.


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


Features and benefits:

  • BBA certified (certificate 19/5609) for use in multiple build-ups.
  • A BBA-accredited 3D U-value calculation service is available.
  • Made with a water-repellent additive - slabs will maintain their integrity while exposed on site.
  • Non-combustible A1 Euroclass Reaction to Fire classification.
  • Good sound absorption characteristics provide high levels of sound reduction.
  • Suitable for use on all buildings including those above 18 m in height providing compliance with fire related building regulations.
  • Contributes to building regulation compliance without reliance on separate testing or desktop studies.
  • Provides an exclusive combination of thermal, fire and acoustic performance.
  • Can be installed either way round on site without compromising performance.
  • A+ generic BRE Green Guide rating.
  • Durability: Odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. The product will have a life equivalent to that of the wall structure in which it is incorporated.


Lightweight but rigid enough to resist the compression forces generated when fixing the insulation slabs to the buildings substrate.

The water repellent additive provides a further line of defence against rain penetration.


Standards and certification:

  • Assessed by the British Board of Agrément (BBA) under Certificate 19/5609 PS1 for use in rainscreen facade systems on new and existing timber, steel-frame, reinforced concrete or masonry walls.
  • Further assessed under Certificate 19/5609 PS2 for use in new and existing partially filled steel frame or timber frame walls with a masonry outer facade.
  • Approved to be used in situations where it bridges the DPCs of the inner and outer leaf because it does not absorb water by capillary action. It is certified for thicknesses from 50 to 250 mm.


The certification offers evidence that the slab is fit for its intended use and will have a life equivalent to that of the wall structure in which it is incorporated, provided that it is stored and installed correctly.


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.


Real performance:

Glass and rock mineral wool are easier to install correctly than other insulants such as rigid boards because 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.


Environmental:

Contains no ozone-depleting substances or greenhouse gases. For further environmental information consult the relevant Environmental Product Declaration (EPD), available on the manufacturer's website.


Moisture:

The physical and chemical characteristics of the fibres are unaltered by wetting. Therefore the thermal properties of the slab are not affected by exposure to moisture and the product will perform as expected once dry.


Thermal performance:

The U-value of a proprietary rainscreen facade system is dependent on the degree of thermal bridging in the system. Calculations should be created using 2D or 3D modelling programs which comply with the methodologies detailed in BS EN ISO 10211.


Consult the manufacturer for details of 3D numerically modelled U-value calculations compliant with BS EN ISO 10211 under the BBA/TIMSA U-value and Condensation Risk Analysis Competence Scheme.
