FIXINGS FOR LEAD
- Fixing clips are required for securing free edges of lead sheet against wind lift.
- Copper or stainless steel fixing clips are recommended for most applications.
- Cast lead domes are the preferred alternative to lead burning exposed fixings and can be used with lead sheet or lead clad steel panels.
- Copper and stainless steel annular ring shank nails are recommended for fixing sheet and clips to timber.
PREMIUM FIXING CLIPS AND STRIP
Premium Roofing Products provide a selection of fixing clips together with strip, from which fixing clips of the desired size may be cut. Both clips and strip are available in copper and stainless steel. Clips either from 0.6mm gauge copper or 0.4mm stainless steel are normally recommended. However, when clips are required to be malleable enough to follow complex profiles, only copper clips can be used. Steel clips are preferred when the clip can only be fixed at its top extremity and rigidity is required, e.g. over a glass roof.
PREMIUM ANNULAR RING SHANK NAILS
Premium Annular Ring Shank Nails are available in both copper and stainless steel. These are recommended for fixing thelead sheet panels, clips etc. to a timber substrate.
PREMIUM CAST LEAD DOMES
For intermediate cladding fixings and for fixing to stone masonry, brass or stainless steel screws are required. For intermediate fixings, the screw must be covered. Premium Cast Lead Domes are ideal for this application as they are supplied as sets of brass screws, lead buttons and serrated edged washers, over which the buttons are crimped.
ADVICE ON USE
- Clips should not be less than 50mm wide.
- In sheltered conditions, copper and stainless steel clips may be fixed at a maximum spacing of 500mm for each lap of lead sheet. Clips should be spaced more closely in exposed situations.
- Clip strength is increased the closer the clip is fixed to the free edge of the lead sheet or flashing. Although fixing near the base of the clip is not recommended for lower pitched roofs, due to the risk of water penetration through the fixing hole.
- An expansion gap of at least 6mm should be left between the edge of the lead sheet and the clip to allow for thermal movement.
- Positions of fixings, particularly intermediate fixings, should be chosen carefully so that the thermal movement of the lead sheet is not impeded.
- The nylite washer included in the Cast Lead Dome Set is specifically for use with lead clad steel and can be omitted when fixing lead sheet.
