  Aluflash

  

  Aluflash is a flexible, environmentally friendly alternative to lead as a weathering flashing material for buildings. It is aluminium based and available in two unique surface finishes depending on the application.

  Embossed Finish

  The embossed finish is designed for applications requiring less complex shapes such as pitched roof valleys, secret gutters, soakers for slates and double lap tiles and box gutter.

  Corrugated Finish

  The cross corrugated finish allows up to 25% extensibility and is designed for use where the flashing has to be moulded over and around complex shapes such as profiled roof tiles and corner junctions.

  Benefits

  • Minimum 30 year design life.
  • Non-toxic. No potential hazards for installer and no contamination of run-off water.

  • Easy to form over a range of roof profiles without the need for specialist skills or tools.
