Here you can find an overview of all of the additional processes, such as perforating, crimping , smooth curving, that you can have on the profiled cladding. There is also information about the usage and application of protective film and anti-condensation foil.
If the acoustic requirements so demand, you can have the profiled roof and wall cladding and structural inner linings perforated. But you can also request perforation just because you think it's attractive. Should you opt for perforation, however, please bear in mind that this alters the permissible load and the deflection of the materials. You can read more about this in the technical manual. SAB supplies two standard perforated patterns: Perfo 3 and Perfo 4.
Crimping entails bending a panel at a certain point to create an angle. Each crimp creates an angle of between 1 and 5 degrees. The spacing between the crimps must be at least 32 mm. The panel must remain straight for at least 150 mm on either end before the first crimp.
Smooth curving entails rolling the sheet into a continuous curve. Smooth curving can only be applied along the entire length of a sheet.
Cold roof cladding (but also façade cladding and warm roof cladding) can be fitted on the inside with an anti-condensation foil to prevent the dripping down of condensation. Anti-condensation foil is especially intended for inside use. It is not suitable for use in humid rooms or in rooms with a permanently high humidity, where there is no ventilation and/or where the absorption surface cannot dry. Anti-condensation foil is also suitable for canopies exposed to (reduced) humidity. The light-grey anti-condensation membrane comprises fibres that clasp together, but which provide sufficient space to absorb condensation. When the temperature rises and there is ventilation, the moisture absorbed is released to the air. Apart from the good moisture-absorbing properties (500 to 900 gr/m²), the membrane also offers extra sound absorption. For headed overlap and ends above the drain (over a width of 200 mm), it is important that profile plates with anti-condensation foil on the building are finished with an air drier. The heating causes the membrane to deform, which prevents the sucking in of water from outside.
SAB can apply a protective film to all coatings and aluminium to prevent damage. This film is applied as standard to all stainless steel and the exterior skin of sandwich panels. SAB-profiel firmly recommends that all smooth coatings, such as polyester and PVDF, should always be ordered with protective film. This film can be easily removed either immediately prior to or following installation.
