Why Custom Flashings Matter on Every Project

Standard off-the-shelf flashings rarely fit site conditions precisely. Gaps, overlaps, and poor detailing at junctions let water in and compromise the building envelope. Custom folded flashings manufactured to your exact dimensions eliminate these problems.

  • Manufactured to suit site conditions and construction details
  • Ideal for roofing, facades, and external wall insulation systems
  • Colour matched for a clean, coordinated appearance
  • Manufactured in lengths up to 4 metres
  • Improves weather protection at critical junctions
  • Powder coated in any RAL Classic colour
