OPTIMA Shingles



Shingles have been around in one form or another for hundreds of years. Sotech still offer traditional copper and zinc shingles, but the range has been extended to aluminium and stainless steel. Unlike our rainscreen systems, shingles do not need a bracket and rail carrier system. Shingles fix directly onto a suitable backing wall with stainless steel clips. The clips hold the shingle and then the next shingle overlaps to create a secret fix seam.

As the shingles are fully supported on the backing wall, they are ideal for thinner gauge metals, which tend to rise and fall at the edges to form the overlaps and underlaps. These subtle profile changes add another dimension to how the chosen shingle material can reflect and responds to changing light conditions.

Benefits of the Optima Shingles System

  • The plywall should be covered with a weather membrane prior to fixing the shingles
  • Simple tophats can be fixed creating airspace in front of the primary structure in whatever direction the shingles are aligned and the shingles can be clipped back to the tophat
  • Suitable for all types of wall constructions either new build or refurbishment
  • Shingles are fixed by stainless steel clips to the profile sheet.
  • Shingles are a series of interlocking shapes retained to the building via stainless steel clips.
  • Optima substructure is fully adjustable and can be installed to support a plywood cloaking.


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.



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.


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.
