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.

Edinburgh Craftsmanship Since 1970

Why engineered timber

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.

  • Quality 01 of 07

    Pressure-treated against rot

    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.

  • Quality 02 of 07

    Three coats, sealed in the factory

    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.

  • Quality 03 of 07

    Cross-laid, layered sections

    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.

  • Quality 04 of 07

    FSC-certified, fast-growing sources

    Sustainability

    Engineered timbers use smaller pieces of wood from fast-growing, renewable, FSC-certified sources. Less waste, and a longer service life.

  • Quality 05 of 07

    Minimal movement, year-round

    Stability

    Cross-laid grain layers give minimal warping or movement. Sashes and doors keep sliding and closing as they should, year-round.

  • Quality 06 of 07

    Every window quality-checked

    Consistency

    More even grain, fewer knots and blemishes. Every window goes through quality-control checks before it leaves the workshop.

  • Quality 07 of 07

    Built to last 60+ years

    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.

Invest In Your Property

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.

Why we use engineered timber
  • 01

    Raise Your Property Market Value

    Beautiful, handcrafted timber windows that boost kerb appeal on Edinburgh's period market.

  • 02

    Reduce Your Energy Bills

    A+ rated double glazing reduces heat loss by up to 60%, saving on heating year after year.

  • 03

    Reduce External Noise Levels

    Sound reduction of 30-35 dB, up to 80% with secondary glazing.

  • 04

    Reduce Heat Loss

    Pressure-treated, cross-laminated engineered timber resists Scottish weather year-round.

  • 05

    Designed to Prevent Condensation

    Say goodbye to misted-up windows. Our design keeps the inner glass warmer, reducing condensation for a clearer, drier home.

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.

  • “Sash and Case / B+M Joiners did a great job replacing windows in my New Town property with modern double-glazed - excellent quality, fit, and finish. Team was responsive, courteous, and skilled, and finished the job on on the timeline they advised to us. My only tiny quibble was that they needed to schedule a 2nd measurement appointment for fabrication after the 1st appointment for estimation - the timeline ultimately worked out, however !”

The joiners did an excellent job from start to finish: professional, reliable, and highly skilled craftsmanship throughout. The new windows look fantastic, perfectly suit the character of the property, and the quality of the finish is outstanding. Everything was completed with great attention to detail and the work area was kept clean and tidy at all times. I am very impressed!”

  • “WOW, my new wooden sash & case windows are absolutely stunning. Thank you so much to Danny and Mark and the Team with their incredibly skilled craftsman Joiners, for making my whole experience from beginning to end an absolute joy. Since buying my old Property in 2024, I inherited old, rotten, drafty, couldn't even open 'non original' design sash and case windows, which were probably installed in the late 1980s/90s. B&M Joiners removed the 'not fit for purpose' old ones and reinstalled with my new stunning Georgian 6/6 sash and case wooden windows. Windows in keeping with the age of property. Quite simply exquisite. The Joiners took great care of the inside of my property too and brought with them endless amounts of dust sheets. Leaving me with a very tidy clean house for my return, exactly as I had left it. A first class service was provided to me from B&M Joiners/Sash & Case Windows Direct. I'm walking on air with my beautiful and stunning new windows. A fantastic experience all round. Thank you so much. I can't recommend this company highly enough. Excellent customer service and great price too. An absolute Joy. A true Company to be proud off.”

  • “We couldn't be happier with our new heritage sash windows. The team at Sash & Case were brilliant from the first survey through to installation. Callum's measurements were precise, and Ewan's fitting team were careful, tidy, and genuinely lovely to have in the house. The windows are beautiful and our home is noticeably warmer. Worth every penny.”
