Storage & Handling of Materials
All rolls of single ply membrane and components must be placed carefully and stored on a clean, dry and level surface. The rolls are usually individually wrapped with protective film and may be stacked on pallets 3-4 rolls high. This wrapping is for protection in transit and handling of individual rolls. It is not a suitable weather protection.
Insulation boards must be protected from weather (preferably by dry storage) on the site and during installation (the wrapping on boards as delivered is not a suitable weather protection). If internal storage is not possible, the boards must be protected by a waterproof sheeting, secured against wind load and fitted such that some air movement below is possible, to avoid accumulation of condensate.
Routine good-site practices should be observed at all times, including care in the handling of scaffolding and other builders’ plant, by avoiding the mixing of cement or mortar on the roof surface and by avoiding storing material of any kind directly on the surface.
