Clad Wood

Loewen clad engineering creates extraordinary strength and durability, enabling dramatic design, innovation and inspiration. Loewen Clad and Wood fenestration products use coastal Douglas Fir or Mahogany in frames and sashes. Our low maintenance extruded aluminum is applied for the ultimate in strength, performance and finish longevity. Loewen uses only pre-finished extruded aluminum cladding to better protect window and door exteriors and eliminate the need for painting. Robust design and engineering can achieve the ideal solution for any opening. Complete your vision with sharp design, customizable options, and the wide-open views that only Loewen can provide.


Loewen Wood products feature only* Coastal Douglas Fir or plantation-grown Mahogany in our frames and sashes. These woods do more than just give our windows a rich, warm texture – they’re also naturally tough and resilient, yet remarkably workable, meaning they are ideal for precision milling and capable of holding the smallest, most intricate detailing. To enhance our woods’ high natural resistance to moisture absorption, decay and insect infestation, every Loewen wood component is treated with a water repellent, wood preservative before assembly. Douglas Fir is North America’s most plentiful softwood species, accounting for one-fifth of the continent’s total softwood reserves. It is beautiful and durable, making it the ideal species for fenestration and a hallmark of the Loewen all wood offering. Versatility is one of the key elements in the Loewen product offering – there are endless possible combinations of standard Loewen products.
