  • 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)
  • Designed for maximum flexibility, the Loewen Timber Curtain Wall system allows for configurations of operating doors and windows, and can be designed for load bearing applications if required.

  • 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

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.
