AUTHENTIC SASH WINDOW DETAIL
At Sash Windows UK, we excel in replicating period features with precision when working on period redevelopments or new builds with traditional designs. Our expertise ensures that elements such as glazing bar layouts, moulding, horn details, and overall shape are meticulously designed and manufactured to closely match historical specifications. Whether you’re restoring heritage properties or incorporating period features into new developments, our attention to detail and commitment to authenticity make Sash Windows UK the ideal partner for your project.
TAILORED HIGH PERFORMANCE
Our timber sash windows comply with the latest Part L Building and PAS24 Regulations, ensuring exceptional energy efficiency and security. With double glazing, we deliver U-values starting at 1.4 W/m²K. For ultra-low energy retrofits, our vacuum glazing systems can reach U-values as low as 0.8 – 1.0 W/m²K. Sash Windows UK offers tailored energy-saving solutions for both modern and traditional properties.
SPRING OR CORD SASH WINDOWS?
We provide both cord and counterweight or spring balanced opening systems to suit your project’s requirements and budget. The cord and counterweight system is considered the premium option for sash windows, while the spring balanced system offers a more budget-friendly alternative. Whichever you choose, both come with the assurance of a robust 20-year warranty for lasting peace of mind.
ADVANCED PAINT PROTECTION
Every window is treated using our highly specialized 5-stage Teknos spray system, providing superior protection and durability for your sash windows. Available in a wide range of colours, with the option to specify different finishes for internal and external surfaces, we offer the flexibility to meet the exact specifications of your project. This process ensures long-term performance and aesthetic quality, making it ideal for high-demand commercial and residential applications.
