Curtain Wall — Loewen Windows

Timber Curtain Wall

The Loewen Timber Curtain Wall system offers large glass assemblies with extremely narrow mullions. Our structurally engineered timbers create a beautiful and warm interior, while the exterior covers are available in painted or anodized extruded aluminum, solid wood, or Cyprium - copper or bronze cladding.


  • Our structurally engineered wood timbers are available in Coastal Douglas Fir (standard) as well as optional species, including Honduran Mahogany and White Oak
  • In addition to aluminum clad, optional exterior cladding is available in Coastal Douglas Fir, Honduran Mahogany, and Cyprium (Copper or Bronze)
  • Pre-assembly at our facility (including fasteners and gaskets) ensures a smoother jobsite installation
  • The water management system is designed to drain water through the verticals – this eliminates unsightly drainage holes in the horizontal faces that can leave streak marks on the glass surfaces below

The best way to get up to speed on our products is an in-person walk-through with one of our product experts. Since that’s not always possible, we’ve produced some videos to explain operation, features, and options.

Exterior Styling

Metal-Clad or All-Wood

Our Timber Curtain Wall exteriors can be metal-clad (extruded aluminum) or non-clad (all wood). To understand all the exterior styles available, hop over to our Colors & Finishes page. You’ll want to look at the clad colors and wood paints & stains.

Interior Styling

The Warmth of Wood

The interior of our Timber Curtain Walls will be a beautiful and high-performing wood species. Our standard of course is Coastal Douglas Fir, but alternative species like Honduran Mahogany are also available. You can leave the interior with a simple clear coat, stain it, or paint it. To see our limited pre-finishing options, see our Colors & Finishes page.
