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 50 kPa (0.5 kg/cm²) with deformation limited to a maximum of 10%. The insulation must also be dimensionally stable up to 100C. All insulation must be kept dry and protected prior to metal covering being laid. |
Breather membrane | |
Material | ISO-Mat Pro® underlay. Guidance for specification option: Recommended for wall or cold roof applications. Envirotect Class B-s1,d0 fire membrane. Guidance for specification option: Can be used when a non-combustible option is required. Manufacturer guidanceThe breather membrane must comply with EN 13859-2 for walls and must also be CE compliant. The breather membrane must be fully supported, lapped and sealed and then further sealed to all surrounding abutments and surface penetrations. A breather membrane is commonly used as a separating underlay, when the metal is being used in conjunction with a metal substrate, to reduce noise. |

Fire classification | Reaction to fire: A1 To EN 13501-5. External Fire Performance: Class BROOF (t1). |
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 VB must have a minimum water vapour resistance of 4000MNs/g and comply to BS SO 12572. The VB 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 regardless of being ventilated, unventilated cold or warm in design. The VB must be positioned behind the insulation and on the warm side of the construction. |
Fasteners | Timber - stainless screw, SPT-R-S-4.3x20-RS. Metal - stainless screw, SX2-D9-4.8x22. Metal - stainless screw, DS3-SS-SF-4.8x16. Manufacturer guidanceFixings to suit substrate. |
