OPTIMA FLASHINGS
Precision-Engineered Flashings for Complete Facade Detailing.
Sotech Optima Flashings are manufactured to provide essential weather protection, clean detailing and seamless integration across the building envelope. Designed for use with rainscreen cladding, curtain walling and other facade systems, they help prevent water ingress at vulnerable junctions, edges and interfaces while maintaining a consistent architectural finish.
Produced under controlled factory conditions, each flashing is fabricated with precision to ensure dimensional accuracy, reliable fit and efficient installation on site. Available in a wide range of standard and bespoke profiles, Optima Flashings can be tailored to suit both straightforward details and more complex project requirements.
KEY BENEFITS
Manufactured in a wide range of materials, with a broad choice of finishes, they deliver durability, performance and appearance.

Interact with the Optima Flashings using the 3D model. Rotate, zoom and gain a better understanding of some of our offerings and how they can benefit in your next project.
Using the 3D model can help during early design stages to:
- Understand the general system construction and build-up.
- Visualise integration on new build and refurbishments.
- Explore the durable, weatherproof protection and seamless integration across the building envelope.
- Available in a wide range of standard and bespoke profiles.
Optima Flashings are designed to provide a clean, aligned appearance, while being robust and low-maintenance that accommodates thermal movement.

OPTIONS
At Sotech, we’re able to manufacture bespoke flashings tailored to individual project requirements, alongside standard solutions for a wide range of applications.
Check out below some of what we are able to produce.


ANODISED ALUMINIUM
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.
Fire Performance of PPC
PRE-PAINT ALUMINIUM
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.
