Every Component. Every Joint. Every Detail.
From sash cords and pulley wheels to glazing bars, parting beads and pivot pins, every part of a traditional Sash & Case window is handcrafted in our Edinburgh workshop from pressure-treated engineered timber. 55+ years of expertise, built into every detail.
How do Sash & Case Windows Direct's engineered timber windows outperform 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. The result is superior durability, stability and resistance to moisture, with long-lasting performance and minimal maintenance.
Preservation
Our timbers undergo a proprietary pressure treatment to extend their life, making them highly resistant to rot, decay and insects. This stabilises the wood, reducing moisture absorption and preventing the sweating and shrinking that open gaps and draughts.
Factory paint finish
Factory finishing outlasts site painting. The timber is coated under controlled humidity and temperature, then sealed with three layers of water-based microporous Sherwin-Williams paint or stain.
Strength
Smaller pieces of wood are layered with the grain running in different directions. That composite is stronger and more stable than a single solid section.
Sustainability
Engineered timbers use smaller pieces of wood from fast-growing, renewable, FSC-certified sources. Less waste, and a longer service life.
Stability
Cross-laid grain layers give minimal warping or movement. Sashes and doors keep sliding and closing as they should, year-round.
Consistency
More even grain, fewer knots and blemishes. Every window goes through quality-control checks before it leaves the workshop.
60+ year lifespan
Premium engineered redwood and Grandis hardwood are built to last 60+ years with the aftercare we specify. The lifespan protects the look of the property and the value of the investment.

Enhance your property's market value with engineered timber Sash & Case windows.
Upgrading to engineered timber Sash & Case windows is a smart choice for your home's value, kerb appeal and efficiency. Cross-laid, pressure-treated timber keeps the traditional profile while resisting the warping that lets heat and draughts in.
A 60+ year lifespan and a factory Sherwin-Williams finish mean the investment holds its look and its energy performance, rather than needing early replacement.
FSC-certified timber from renewable sources, less waste than solid stock, and a finish that lasts: the windows raise the property and lower the running cost.

Our dedicated craftsmen produce a finish that is second to none.
Sash & Case Windows Direct was recommended to me by a friend of mine that is a historic building's architect and my experience of the company has been entirely positive. I cannot thank you enough, the two young and enthusiastic craftsmen who came to do the work knew exactly what they were doing. They were extremely helpful and in fact a delight to have in the house.

We recently had the pleasure of using Sash & Case Windows Direct for the installation of new windows in our Edinburgh property. From the outset, we were incredibly impressed with their professionalism and expertise. The team of joiners were not only highly skilled but were also friendly and approachable, making the entire process smooth and hassle-free. They took the time to explain the procedure, answer any queries we had, and ensured our satisfaction at every step. The windows themselves are of exceptional quality, a testament to the craftsmanship and attention to detail the company puts into their work. They have truly transformed our home.
