The greenhouse is made from cedar and glass. The windows are traditionally constructed with mullions and muntins. The “frame within a frame” method of construction uses more wood but allows natural wood movement and also makes it possible to remove window frames or to dissemble the greenhouse completely. All horizontal sills are given a 5 degree slope to shed moisture. 8′ sidewalls and 12/12 pitch roof provide sufficient ceiling height to create a chimney effect that keeps the greenhouse air fresh. Good ventilation means that the greenhouse stays cool even during the hottest summer months while the clear glass collects all available solar energy during the shoulder months. Careful thought went into incorporating classical architectural features. Only highest quality screws, glue, and sealant used.

The greenhouse is nearly indestructible. It went through a powerful hailstorm west of Innisfail that cracked windows and windshields (on both of my vehicles), broke siding, and destroyed shingles on all of the houses in the area, but the greenhouse was unscathed. This is due in part to the strength of a 1/4″ pane of glass fitted into a wooden frame that absorbs impact. Another advantage of wood is that it does not conduct cold into the greenhouse. Finally, cedar is naturally rot resistant. The wood is further protected from the elements with two coats of Sashco Capture stain and one coat of Saschco Cascade clear coat.
