Specification data - Pressure-equalized rainscreen cladding systems
Classification data | |
Thermal insulation | Manufacturer guidanceRainscreen cladding does not have any specific requirement with regard to the insulation. Insulation must be structurally self-supporting or supported when installed so that it will not sag and form unvented voids or cause loss of thermal efficiency. An insulation used as a directly supporting substrate must have a minimum compression strength of 50kPa (0.5 kg/cm2) with deformation limited to a maximum of 10%. The insulation must also be dimensionally stable up to 100°C. All insulation must be kept dry and protected prior to metal covering being laid. |
Breather membrane | |
Material | Envirotect Class B-S1,D0 Fire Walling Membrane. Guidance for specification option: May be used when a non-combustible option is required. ISO-Mat Pro® underlay. Guidance for specification option: Recommended for cold vented substrate applications. Manufacturer guidanceThe breather membrane must comply with EN 13859-2 for walls and must also be CE compliant. It is commonly used as a separating underlay, when the metal is being used in conjunction with a metal substrate, to reduce noise. |
Fasteners | Manufacturer guidanceThe breather membrane must be fully supported, lapped and sealed and then further sealed to all surrounding abutments and surface penetrations. |
Secondary support structure | As design. |
Cavity fire barriers | |
Horizontal | To BS 9991. |
Vertical | To BS 9991. |
Cladding panels | |
Material | Cor-Ten. |
Panel joints | Longitudinal joints: Shadow gap with panel closed ends, refer to drawings. |
System accessories | Manufacturer guidanceAll associated flashings to match can be fabricated from coil by Metal Solutions Ltd as per typical details and industry standards. Associated rainwater goods in various sizes and profiles are available in the same material. Consult manufacturer for details and insert requirements. |

Stainless screw, DS3-SS-SF-4.8x16. Guidance for specification option: For fixing to metal. Manufacturer guidanceFixings to suit substrate. All associated flashings to perimeters and openings available upon request from Metal Solutions. |
Colour/ Finish | Cor-Ten. |
Size and profile | 300 x 6000 mm. Guidance for specification option: As standard. Other. Guidance for specification option: Narrower and variable widths available on request. Longer lengths on request. |
Weight | 0.9 mm material weight 7.12 kg/m². Guidance for specification option: System weight dependant on panel size and shadow gap. |
Fire classification | Reaction to fire: A1. Guidance for specification option: CWFT – Classified without Further Testing (EU fire protection standards). |
Thickness | 0.9 mm. |
Air and vapour control layer | Manufacturer guidanceVapour barrier membranes must comply with EN 13859-2 for walls and must also be CE compliant. For fully supported metal cladding the vapour barrier membrane must have a minimum water vapour resistance of 4000 MNs/g and comply to BS SO 12572. It also must have a resistance against a supported column of water 2m high for a period of 15 mins to comply with DIN EN 20811. All cladding must have a vapour barrier membrane regardless of being ventilated, unventilated cold or warm in design. The membrane must be positioned behind the insulation and on the warm side of the construction. |
