Optima XTR Wave: Where Curves Meet Design Magic

XTR Wave is a groundbreaking addition to our Optima XTR extrusion collection.  The unique extrusion offers four specially curved profiles that work in perfect harmony to craft facades that are not just curved but also richly dimensional.

Optima XTR Trigon: Trigon XTR Extrusion Modernises Facades

Introducing Optima XTR Trigon extrusion.  Trigon redefines the conventional geometry of facades by focusing on one of the most fundamental shapes: the triangle.


Anodising is an A1 non-combustible finish. It is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

Due to the nature of the anodising process and the tight quality controls on both the aluminium and the surface treatment, anodising has a homogeneous (matching & consistent) appearance.

Colours, textures and patterns can be incorporated in the anodic film, enhancing the natural metallic appearance without affecting the total UV resistance of the rainscreen cladding.

Anodising enhances the natural qualities of aluminium further; it permits a strongly contemporary finish with incomparable corrosion and abrasion resistance.

Aluminium is exceptionally recyclable, requires minimal maintenance and has proven lifetime performance.

Polyester Powder CoatED ALUMINIUM (PPC)

PPC is an A2 limited combustibility finish.

PPC is a type of dry coating, rather than a conventional liquid paint, and is applied to metal rainscreen as a free flowing, dry powder. The powder is applied to rainscreen panels electrostatically and is then cured under heat to allow it to form a ‘skin’. This electrostatic powder process means we can ensure complete coverage of the panels, even on more complex shapes.

Powder Coating can produce a much thicker coating than conventional liquid coating leaving PPC rainscreen cladding with a hard finish. This is much tougher than normal paint and its strong abrasion and corrosion resistance properties make it extremely durable and long lasting.

If you are looking for a finish to make your project stand out PPC is a great specification choice with a range of 200 standard RAL colours and a wide choice of special effects offer a great alternative to anodised aluminium and stone, natural effects and different textures can be used to add a unique touch to your project.



The CWCT ‘Standard for systemised building envelopes’ gives a framework for specifying building envelopes and provides a ‘Specifiers checklist’ showing information that will change from project to project.

This includes:

  • Internal and external environment
  • Air permeability
  • Thermal performance
  • Access and safety
  • Design life

Learning Zone

Learn More…

The Learning Zone plays host to innovative design workshops, CPD seminars and launch events where designers, contractors and material manufacturers can meet, evaluate and review projects and address technical issues at the very start of the design process.

We also have constructed training walls where installation teams can come and familiarise themselves with our Optima Rainscreen Systems, and products can be tried, tested and handled prior to going on site.


There is a huge range of materials, finishes, colours and design options, offering the specifier an almost limitless choice of products, presented in a practical and convenient way designed to cut research time for the designer and provide an in-depth technical resource.


Experience the range of systems and choice of materials, explore technical solutions to specific problems, iron out design details and gain an understanding of scheduling requirements.  All systems can be examined in detail and real-life applications can be rigorously reviewed and tested.
