Aluminium Flashings for waterproofing membrane termination

Description

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:

  • 0.8mm – 1.2mm for standard waterproofing applications

  • 1.5mm – 2.0mm for high-exposure or heavy-duty conditions

• Lengths: Standard 3m or 6m lengths, custom sizes available on request

Profile Dimensions & Configurations:

1. Flat Flashing – Width: 50mm – 150mm, used for general membrane terminations

2. Drip Edge Flashing – Overhang: 25mm – 50mm, designed to direct water away from the structure

3. Angle Flashing (L-Profile) – Sizes: 50x50mm, 75x75mm, 100x100mm, for corner terminations

4. Capping Flashing (Z-Profile or Coping Cap) – Width: 100mm – 300mm, used for parapet wall protection

Installation Considerations:

• Fastening: Secured with stainless steel screws, rivets, or adhesive bonding

• Jointing: Overlapping of 50mm – 100mm, with optional sealant application for waterproofing

• Expansion Allowance: Thermal expansion gaps recommended every 3m – 6m

These aluminium flashings are widely used in roofing, façade waterproofing, podium decks, and external wall terminations, ensuring a robust and weatherproof system.
