The NZ Metal Roof and Wall Cladding Code of Practice is a comprehensive design & installation guide, and a recognised related document for Acceptable Solution E2/AS1 of the NZ Building Code.
Strippable film is a clear pressure sensitive polyethylene plastic film that is applied to some roofing products to assist in protecting the surface from damage and scratching during forming, transportation, handling, storage, and erection.
Strippable film is designed to provide some protection to the product before and during installation on the building. It is not designed to protect against corrosion, humidity, or chemicals.
Strippable film must be removed before prolonged exposure to sunlight, as that may make it extremely difficult to remove. Prolonged exposure and wet conditions can also cause the film adhesive to whiten and breakdown, leaving residue on the painted surface when the film is removed. Once removed from the sheet for installation, strippable film must be collected and removed from the site.
