The 2″ x 2″ clear grade, dried redwood framing is naturally resistant to insect and moisture damage. It resists warping in moist or dry environments. No protective treatment is necessary. Only second growth redwood is used in the Gardenhouse, preserving old-growth redwood forests. The frame base is 2″ x 4″ plastic lumber made of 100% recycled plastic. It is impervious to rot, mildew and insects and matches the redwood frame’s color.
Virtually unbreakable polycarbonate is the same high-tech plastic used in aircraft windshields and helmets. Temperature extremes don’t affect its impact resistance. Hail and baseballs bound off. Its impact strength is 30 times greater than acrylic and 200 times greater than glass. After glass, polycarbonate is the most flame resistant glazing.
Double-wall panels retain heat to help plants stay 10-20°F warmer in winter. If you use a heater, you’ll save 40% of the cost of heating a single-pane glass greenhouse. Design maximizes the quality of light for full, straight and even plant growth. Sunlight is scattered by the ribs between panel walls to surround plants without shadowing or burning them.
UV-resistant additive in panels blocks 98% of the harmful UV rays while transmitting 83% of the visible rays that plants need for maximum growth. Plants are more productive. Panels won’t crack or shatter. They may be cut with a fine toothed saw, allowing easy installation of plumbing or heating equipment.
Major components are panelized for an easy, sure fit. Panelized sections are joined by screws. A power screwdriver, a 6′ stepladder and a tape measure are all that’s needed for easy assembly. The 6′ x 8′ model takes about 3-4 hours to assemble. Even the 8′ x 12′ model takes less than a day for a “non-builder” to complete.
Exceptionally rigid and lightweight, only the corners of a Gardenhouse need to be anchored to the ground.
Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F. As it cools and the paraffin contracts, the operator’s springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.
The roof vent allows air to escape at the hottest point, the roof ridge. Cooler air enters the base vent, creating a chimney effect and circulating cool fresh air throughout the Gardenhouse. The convenient Dutch door provides additional ventilation control and easy access.
The optimum 45 degree roof slope transmits low angle sun in the winter and reflects high angle sun in the summer. This increases heat in the winter and reduces it in the summer. It also leaves lots of headroom and plant hanging space. The steep roof slope sheds snow in the winter and can withstand a snow load of 18 lb. per square foot.
Specially designed matching redwood benches are available that run the full length of the Gardenhouse. Benches are 21″ deep for all models except the 8′ x 12′ and 8′ x 16′ models, which are 30″ deep. They can be stacked to provide additional growing surface.
The 6′ x 8′ kit is packed in four boxes; the 6′ x 12′ kit is in five boxes; the 8′ x 12′ kit is in seven boxes. Maximum weight of any box is 85 lb. and any one of the kits will fit into a standard size pickup truck.
The Sunshine Gardenhouse is guaranteed to be free from defects in materials and workmanship for five years from the date of purchase. The polycarbonate glazing is fully warranted against excessive discoloration for the first five years and has a prorated warranty the second five years.
