The WBS Mineral Fibre Insulated Render System offers a versatile solution for both new build and refurbishment applications and is ideal for use on a variety of substrates including brickwork, blockwork, steel and timber frame, and structural insulated panels (SIPS).

WBS Mineral Fibre boards are manufactured without the use of CFCs or HCFC’s and therefore have a Zero ODP, is a non-combustible insulant classified as Class A1 – (BS EN 13501-1: 2002), and is therefore ideal for use on highrise applications or schools where spread of flame control is of significant importance.

The WBS Mineral Fibre Insulated Render System can be finished using a variety of final finishes or textures including thin coat silicones & acrylics, cementitious renders, dashing aggregates and brick slips.


  • Offers a Class O Fire rating – non-combustible insulant Class A1 – (BS EN 13501-1: 2002).
  • Suitable for new build & refurbishment projects.
  • Suitable for high, medium & low rise properties.
  • Acoustic reduction properties – highly suitable for public buildings, hospitals & schools.
  • Allows vapour permeability.
  • Fixing options – mechanical only and adhesive & mechanical.
  • BBA Certified.


  • This system has an assessed anticipated lifespan in excess of thirty years.

Movement joints:

  • Where movement joints are present in the existing substrate, it is highly recommended that they are carried through the WBS system. Please consult with WBS Technical Support for further details on where movement joints are required.

Design Considerations:

  • Should the proposed project incorporate any unique design elements or curved elevations, please contact WBS Technical Support for recommendations or assistance.

Standard product features


- WBS Mineral Fibre insulation boards:

  • Thickness: 30–200 mm.
  • K Value: 0.036-0.038 W/m²K.
  • Thermal calculations are carried out for each project to help to determine the thickness of insulation required to meet current Building Regulation requirements.
  • WBS Mineral Fibre is odourless, non-hygroscopic, rot proof, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

- Fire performance:

  • WBS Mineral Fibre is a non-combustible insulant classified to BS 476-4: 1970 (1984) and Euroclass A1 (BS EN 13501-1: 2002), Class 1 Surface Spread of Flame to BS 476-7 1997 and Class ‘O’ to the Building Regulations on a WBS mineral fibre system, fire breaks are not required. Please refer to BR 135 ‘Fire Performance of External and Thermal Insulation for Walls of Multi Storey Buildings’; 2nd edition, 2002.

- Moisture Resistance:

  • WBS Mineral Fibre are non-wicking when tested to BS 2972: 1989: Section 12. When exposed to 90% relative humidity at 20°C, WBS Mineral Fibre absorbs less than 0.004% of moisture. Rocksilk EWI Slab and EWI Slab Plus contain a water repellent additive to ensure that no liquid water is able to pass through the slab and reach the structure.

- Vapour Resistance:

  • WBS Mineral Fibre has a vapour resistance of 7.00 MN.s/g.m.

Product Options


  • Where mechanical fixings are required, the length, type and number of fixings required can only be determined following an on-site pull out test.
  • Secondary pinning may be required on high-rise applications. Please consult with WBS Technical Support for recommendations.


- Polymer modified renders:

  • A range of BBA certified through coloured polymer modified renders are available in a variety of colours. Special colours may be available on request.

- Dry dash:

  • A wide range of coloured dashing mortars and complimentary dashing aggregates are also available. A list of standard colours can be found at

- Flexible Silicone & Acrylic Finishes:

  • WBS flexible silicone & acrylic thincoat finishes are supplied pre-mixed and are available in 100 standard colours. Special colours and colour-matching to other manufacturer's palettes may be available on request. WBS silicone and acrylic finishes are available in four standard grain sizes in the 'K' range and two grain sizes in the 'R' range. Other grain sizes can be acquired on request.
  • WBS Silicone & Acrylic systems are certified for European Technical Approval from the DIBT, Germany. ETA is an EEC wide accepted equivalent to BBA. Standard.
  • Please consult with WBS technical department before specifying any dark colours with a lightness value of less than 20.

- Epsibrick Brick Slips:

  • The basis of the WBS Epsibrick Brick Slip System is the specially profiled galvanised steel/ stainless steel brick mesh which is fixed directly onto the EWI system. The mesh is fixed using specialist fasteners of the appropriate length to give a suitable penetration into all types of substrate, which must comply with wind loading requirements. Due to the overall weight of the system, it is recommended that WBS brick slips are only used up to three storeys.

- Epsibrick 7 mm Brick Slips:

WBS Epsibrick 7 mm Brick Slip System incorporating real clay brick slips adhesively fixed to a high impact, reinforced basecoat. The reduced brick slip thickness makes this an extremely durable, lightweight system, offering a wide range of colours, enabling tenants to retain the look of their original brick façade.
