Unlike other window makers, we use Coastal Douglas Fir (Pseudotsuga Menziesii to be botanically precise) as the standard species in our frames and sashes. This tightly grained wood does more than just give our windows a rich, warm texture— it’s also naturally tough and resilient, yet remarkably workable, meaning it is ideal for precision milling and capable of holding the smallest, most intricate detailing.

To enhance our wood’s high natural resistance to moisture absorption, decay and insect infestation, every Loewen wood component is treated with a water repellant/wood preservative sealant before assembly.

• Douglas Fir is North America’s most plentiful softwood species, accounting for one-fifth of the continent’s total softwood reserves.
• Roughly 88% of the Douglas Fir purchased by Loewen comes from forestland that is Sustainable Forestry Initiative (SFI) certified. In addition to SFI certification, many of our Douglas Fir suppliers in Canada are ISO 14001 and/or CSA certified.
• Douglas Fir — different, durable. The ideal species for fenestration and a hallmark of the Loewen brand.

Windows and doors are active components. They are opened and closed — even slammed! Tight, stable joinery and the ability of fasteners and hardware to remain solidly attached are key factors in a long, dependable working life for your home’s fenestration.
