Fins & screening

Timber fins offer a striking way to add depth, rhythm and architectural interest to façades and outdoor spaces. Used for screening, solar shading or architectural detailing, they provide a low-carbon alternative to aluminium and fibre-cement. Russwood supplies high-quality timber fins alongside engineered fixing systems, with a choice of dimensions, species and finishes to help you create a solution tailored to your project’s design and performance requirements.

Minimum thickness guidelines

To ensure structural stability and safe fixing, we recommend a minimum thickness of 42mm for modified timbers (such as Lunawood, Thermopine® and Abodo®) and 63mm for Scotlarch®. These dimensions are based on best practice, ensuring that screw fixings are positioned at least four times their diameter from the edge of the fin.

Surface finishes

Russwood fins can be finished in a range of surface textures, including brushed, planed, fine-sawn, and Microtex®. If fins are being used alongside cladding, selecting a matching surface finish can help achieve a consistent and cohesive appearance across your project. Our team can advise on the best options to align with your chosen aesthetic and fin dimensions.

Fin fixings

We also offer specialist hidden fixings for fins through our FinFix® and SIHGA LamellenFix® systems. These provide a secure and aesthetically clean solution, allowing uninterrupted timber surfaces and seamless integration into your design.
