Horizontal Interlocking System
- WALL / SOFFIT
Features & benefits
- Provides a smooth, flat appearance with negative details.
- Natural ventilated air flow.
- Solid panel design installed directly on to a galvanised top hat or trapezoidal substructure and fixed directly onto the structural element of the building.
- It is classified as a rain screen system allowing water to enter through the panel surface and drain behind in a ventilated cavity.
- Fully waterproof with the use of membranes, without the use of exposed mastics and sealants.
- Flexibility in overall appearance. Joints can vary from 15–25mm.
- The panels are adaptable in width. Fully non-combustible system.
- Superior quality aluminium, produced overseas and available for use in all our panel systems.
- Alloy 3005 with a temper of H42.
- Pre-painted using a PVDF paint system, using at least two layers to produce a minimum paint thickness of 27 microns.
- Can be used in areas without direct rainfall with no corroding or discolouring.
- Composed of very high quality zinc (at least 99% pure) alloyed with copper and titanium to make it harder and stronger, increasing both mechanical and creep resistance.
- Continues to develop a natural protective layer (or patina) as it ages, self-repairing any marks and scratches throughout its lifetime.
- Lifespan of 70–100 years, depending on exact location.
- As a result of surface oxidisation caused by weathering, copper forms a protective barrier (patina) that resists further corrosion and extends its life.
- This results in ongoing colour changes depending on the environment – from blue-green to nut-brown.
Retains its bright red copper colouring after installation, before forming a protective oxide layer and gradually changing from matt, through a wide range of brown tones, and finally a robust green patina on sloping surfaces.
