Timber fins in modern architecture: innovative solutions for secret fixing
Timber fins are becoming a defining feature in modern architecture. Practically, they provide shade from the sun, while also allowing in natural light – unlike a solid façade would. Aesthetically, they add contrast and make a bold design statement by breaking up solid surfaces. Timber fins can also be used to create interesting shadow play and texture as the sun moves throughout the day. However, the challenge has always been installing them easily while achieving a clean, fixing-free finish—particularly in high-end projects that demand a refined finish.
The challenge: fixing timber fins
Traditionally, specifying timber fins for a project requires a custom solution tailored to the building’s design. This might involve the use of bulky U-clamps or even fully bespoke masking systems. While these methods are functional, they fall short of delivering the refined, hidden-fixing aesthetic that contemporary architectural designs demand. The process also adds complexity and extra work for both architects and contractors, who must devise a solution that not only meets the project’s aesthetic vision but also avoids being cumbersome or time-consuming to install.
The solution: hidden fixing systems
At Russwood, we’re excited to offer two innovative solutions for the secret-fixing of timber fins. Both systems deliver a fixing-free finish for a flawless, high-end finish. Designed with sustainability in mind, these systems are circular-economy ready, allowing timber fins to be easily disassembled, repurposed, reused, or recycled at the end of their life. Engineered for safety and reliability, these systems have undergone rigorous structural assessments, ensuring a safe and failure-free installation. Both systems are user-friendly, with comprehensive installation instructions provided, making the process straightforward for contractors. Whether it’s for smaller fin sections on residential projects or large-scale commercial builds, our systems – Russwood FinFix® and SIHGA LamellenFix – offer a solution tailored to both.
Russwood FinFix®: for smaller fin sections
Designed by Russwood’s in-house R&D team to meet architects’ demands and independently assessed by structural engineers, Russwood FinFix® is specifically designed for secret-fixing smaller timber fin sections in architectural projects. Offering a high-end finish for timber fins with no visible fixings, Russwood FinFix® is fully compatible with the Russwood Battening System and cladding products, ensuring seamless integration without any concerns about component fit. Fin dimensions of 42mm x 68mm, 92mm, or 140mm can be used with Thermopine® and 63mm x 150mm can be used with Scotlarch®. This compatibility adds to the ease of installation with one simple, efficient solution. The simple design ensures no water traps which could lead to potential durability issues. Plus the bracket and screws are made from stainless steel, which avoids any potential staining that occurs with cheaper materials. Both the design and materials used for the bracket have been carefully considered to ensure your fins look good and stand the test of time.
Specifier tip: We recommend using Thermopine® fins with the Russwood Battening System and Russwood FinFix®. This complete system is a stock item, ensuring short lead times for your projects.
