Verified by manufacturer today
Wind Uplift Test Certificate
Certificate type
Concealed-fix aluminium parapet capping with cantilever bracket support, providing durable weather protection, ventilation and secure installation across extended or offset roof-edge conditions.
Application
Aluminium parapet capping system for weatherproofing and ventilating upstanding walls where the capping extends beyond the supporting wall line, using cantilever brackets to provide a secure fixing platform across wider overhangs, insulation zones or façade offsets.
Description
SnapLok Cantilever Bracket Capping provides a secure, secret-fix aluminium parapet capping solution where the roof edge extends beyond the supporting wall line. A purpose-designed galvanised steel cantilever bracket creates a stable fixing platform across wider overhangs, insulation zones and façade offsets, allowing the SnapLok retaining bracket and capping to be securely installed above.
The system combines structural support with a clean architectural finish, maintaining the concealed fixing principle and uninterrupted roofline associated with SnapLok Capping.
Features and benefits:
- Provides engineered support where the capping extends beyond the supporting parapet or wall construction.
- Suitable for wider overhangs, external insulation zones and façade offsets.
- Purpose-designed galvanised steel cantilever brackets provide a stable fixing platform for the capping system.
- Concealed SnapLok retaining brackets secure and align the aluminium capping without visible fixings through the finished surface.
- Avoids penetration of the capping face while allowing ventilation over the top of the parapet construction.
- Suitable for both flat and pitched roof applications.
- Capping widths, internal and external leg depths and section lengths can be manufactured to suit individual project requirements.
- Can accommodate project-specific falls and drainage strategies.
- Available in 1.5 mm, 2.0 mm, 2.5 mm and 3.0 mm aluminium thicknesses.
- Straight, curved, ridged and sloping profiles can be manufactured to suit the building geometry.
- Bespoke welded corners, stopends, abutments, transitions and junctions are available to create a complete coordinated system.
- Independently wind tested to speeds in excess of 400 mph.
- Optional abseil loading support can be incorporated where façade maintenance access is required.
- Available in a wide range of powder-coated, anodised and natural finishes.
- Suitable for demanding commercial, residential and high-rise applications.
