    Key Features
  • Panels may be laid vertically or horizontally - the same principles of sealing and flashing apply.
  • Panels may have 'flat' or profiled external faces. Vertically laid panels with profiled faces can be detailed to minimise the thermal bridge. The liner and sill of the flat panel construction bridge the insulation and the Y value will be high.
  • Internal trim should be typically 1.5mm thick, with sealed joints.
  • Seal to wall/floor must be substantial to cater for inevitable variation in concrete/masonry.
  • Ensure temporary fix for internal trim and fixing for drip flashings do not compromise air seals. Use rivets, and/or remove temporary hex head types, as work progresses.
  • Use fasteners and seals recommended by manufacturers.
