Optima IPC, Interlocking Pressed Plank Rainscreen


PRESSED planks THAT are connected by a simple interlocking male/female joint, which offers either a recessed or hairline appearance.

The Optima IPC, Interlocking Pressed Plank is secretly fixed onto extruded aluminium support framework horizontally, vertically or diagonally in a variety of materials.

As the longitudinal joint is not ventilated this product can be used as a weathered screen introducing ventilation at the base of a wall and at the top or some ventilation can be introduced at the cross plank joints by leaving a gap with the support structure behind creating a baffle.


The Optima IPC Rainscreen system offers a superior approach to traditional cladding with a range of benefits that enhance the functionality and aesthetic of your building. Designed for both aesthetic appeal and performance longevity, it's the ideal solution for modern architectural needs. The Optima IPC Rainscreen system offers an innovative slide and lock adjustment mechanism, with the secret fix hook on rainscreen system enhancing the functionality and aesthetics of your building.

  • The pressed metal plank is available in a variety of materials and thicknesses up to 2mm, enabling greater module sizes far in excess of the limitations found in some rolled systems.
  • The metal planks are connected by a simple interlocking male/female joint, which offers either a recessed or hairline appearance.
  • Flashings and ancillary products available such as copings, fascia soffit, column casings, solar shading, and architectural features.
  • Euroclass A1 and A2 – s1,d0 panel materials up to 2mm.
  • Mechanical fixing methods and no use of adhesives, providing true A1 and A2 cladding systems.
  • The system has been independently tested and certified to meet CWCT rigorous specification for rainscreen cladding.
  • Panels are fixed using wafer head, self-tapping stainless steel screws through pre-punched holes.
  • Panels can be fixed to a simple top hat or timber baton of minimum 38mm depth to create ventilation with a cladding zone as shallow as 90mm.
  • Components meet the requirements of Class 0 fire performance in accordance with building regulations.
  • NBS specifications available tailored to your project.

Building a Reliable Foundation with Quality Materials

The Optima XPC system isn’t just about the panels; the substructure is equally important in ensuring longevity and performance. Built using materials from quality brands, the system guarantees reliability and durability. The system’s adaptability is evident in its suitability for all types of wall constructions, whether for new builds or refurbishments. The fully adjustable system allows for precise alignment and levelling of the cladding zones, accommodating variations in insulation thickness and wall irregularities. This precision ensures a flawless finish and long-lasting performance, keeping the project’s aesthetic and structural integrity intact over time.


Ease and Versatility in Application

Finally, the Optima XPC system’s installation and backing walls are designed with ease and versatility in mind. Compatible with various types of external insulation and wall constructions, it offers solutions for easy installation. The system’s adjustability, along with the use of wafer head, self-tapping stainless-steel screws, ensures a secure and precise installation. Ventilation zones behind the panels are often designed to exceed CWCT minimum requirements, considering structural rails and other constraints. With such detailed attention to functionality, adaptability, and aesthetic, the Optima XPC system provides a comprehensive solution for modern cladding needs.


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.


Copper is an A1 non-combustible material. It is a traditional construction material excelling in durability, malleability and corrosion resistance.

Copper is perfect for architectural cladding, giving a unique aesthetic appearance with low maintenance costs due to a naturally forming, self-protecting patina.

The material is 99.9% recyclable and using only 15% of the energy used in the original manufacture to recycle product.

The material protects itself by developing a patina over time, however patination can be accelerated by a chemical process meaning the material is available in varying shades.

Strong, dimensionally stable, light and low maintenance.

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.



Pre-PAINTED Aluminium is a great choice for large facade cladding projects, tough and hard-wearing.

It is available in a wide choice of colours and surfaces and gives a uniform paint layer and consistent colour minimising shade variation between panels – Euroclass A1 Fire Rating.

In addition to its UV and weather resistance, it is also easy to transform and allows creations of original shapes.

Prepainted metal is the choice for sustainable design, the aluminium coating is an environmentally friendly process and can be recycled without any loss in quality.

Stainless Steel

The appearance of stainless steel panels is easy to maintain, as the material is highly resistant to atmospheric and pure water environments, it is also 100% recyclable and Euroclass A1 Fire Rating.

Rimex offer Stainless Steel patters that are produced by texturing or rigidizing ferrous and non-ferrous metals, increasing strength in all directions.

Textures diffuse light patterns to produce an optical flatness to sheet metals, eliminating the unwanted oil-canning effect. Deep textured metals resist dents and scratches resulting in low maintenance costs.

Richard Austin Alloys provide a complete range of processing services including surface finishing. Using various techniques we can provide you with grades bright, reflective and highly polished finishes.

Stainless Steel is Euroclass A1 Fire rating, the appearance of stainless steel panels is easy to maintain and 100% recyclable.


A traditional construction material excelling in durability, malleability and corrosion resistance due to a naturally forming, self-protecting patina.

Naturally resistance to corrosion and virtually maintenance free as the rinsing effect of rainwater performs this task naturally. Zinc lends itself to both traditional and contemporary design. – Euroclass A1 Fire rating

One of the most unique features of Zinc Composite Material is that it uses the effect of air and the elements to enhance it’s finish; available in a natural blue grey, as well as numerous other shades, ZCM’s pre-weathered finish means that it matures over time as it’s exposed to the outside, and the natural patina that develops means that scratches and imperfections are virtually unnoticeable.

The surface only requires minor cleaning and maintenance over its lifetime.
