Years' expertise
Every Component. Every Joint. Every Detail.
From sash cords and pulley wheels to glazing bars, parting beads and pivot pins — we handcraft every part of a traditional sash and case window. That intimate knowledge is what lets us replace tired windows with bespoke replicas that look, move and last like the originals.
Traditional Craftsmanship. Modern Thinking.
We are Sash & Case Windows Direct. We believe in preserving the traditional aesthetics of your property without compromising on quality. Our handcrafted replacements bring a notable upgrade, improved frames and glass for unmatched performance, while keeping the appearance Edinburgh's period properties were designed for.
A Perfect Window Made For Your Property
There's no one-size-fits-all approach. Every window we manufacture is bespoke, made to measure and quality inspected throughout the manufacturing process. Our bespoke solutions cover a range of profiles to ensure your property gets the right product to suit your needs.
Engineered Timber That Outperforms Traditional Timber
Our engineered timber windows are meticulously crafted using advanced technology and high-quality materials. The process eliminates the inherent weaknesses of traditional timber, warping, twisting and shrinking, through cross-laid grain layers. The result is superior durability, stability and resistance to moisture, with minimal maintenance and a 60+ year lifespan.
Colours, Finishes & Period Features
Our windows are treated with three standard coats of Sherwin-Williams superior water-based paint. This comprehensive application guarantees our paintwork for 10 years. For bespoke aesthetics, we offer a dual finish on all windows, allowing for distinct colours on the interior and exterior. We also incorporate traditional architectural features such as astragals, horns, concealed vents, pulley wheels, sash fasteners, simplex fittings and sash lifts & rings.
Sustainable Sourcing. Engineered Excellence.
Built to last. Built to perform. Engineered timbers utilise smaller pieces of wood from fast-growing, renewable sources, less waste and enhanced sustainability. All our timber is FSC certified, and we are platinum accredited by Zero Waste Scotland.
