Aluminium flashings are essential components in waterproofing systems, providing a secure and durable termination for waterproofing membranes. They protect exposed edges from water ingress, UV exposure, and mechanical damage, ensuring long-term performance and structural integrity. Lightweight, corrosion-resistant, and easy to install, aluminium flashings are widely used in roofing, facades, and foundation waterproofing applications.
Material Specification:
-
Alloy: Typically Aluminium 3003, 5052, or 6061 for corrosion resistance
-
Finish: Mill finish, anodized, or powder-coated for enhanced durability
-
Thickness:
-
0.8 mm – 1.2mm for standard waterproofing applications
-
1.5 mm–2.0 mm for high-exposure or heavy-duty conditions
-
-
Lengths: Standard 2.44 or 3 m lengths, custom sizes available on request
Profile Dimensions & Configurations:
-
Flat Flashing—Width: 50 mm–150 mm, used for general membrane terminations
-
Drip Edge Flashing – Overhang: 25mm – 50mm, designed to direct water away from the structure
-
Angle Flashing (L-Profile)—Sizes: 50×50 mm, 75×75 mm, 100×100 mm, for corner terminations
-
Capping Flashing (Z-Profile or Coping Cap) – Width: 100 mm–300 mm, used for parapet wall protection
Installation Considerations:
-
Fastening: Secured with stainless steel screws, rivets, or adhesive bonding
-
Jointing: Overlapping of 50 mm–100 mm, with optional sealant application for waterproofing
-
Expansion Allowance: Thermal expansion gaps recommended every 2.44-3 LM.
These aluminium flashings are widely used for roofing, façade waterproofing, podium decks, and external wall terminations, ensuring a robust, weatherproof system.
