BEAUTIFUL HIGH QUALITY REDWOOD GREENHOUSE KITS!
The Beauty's More Than Skin Deep!
High quality materials and functional design create the most effective and durable greenhouse. A Sunshine GardenHouse' adds joy to your life and value to your home.
Heavy Duty Twin Wall Polycarbonate Glazing. The Best Greenhouse Glazing Material.
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 bounce 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 10º-20ºF warmer in the 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. Glazing carries a 10 year limited warranty against hazing and discoloration.
Panels won't crack or shatter. They may be cut with a fine toothed saw, allowing easy installation of plumbing or heating equipment.
Automated Ventilation Simplifies Climate Control.
Automatic vent openers 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 65ºF, pushing the vent open to its fully opened position at about 85ºF. As it cools and the paraffin contracts, the operators springs draw each vent closed. Its adjustable within approximately 5ºF and easily detachable for manual operation.
Thorough Air Circulation.
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 greenhouse. The convenient Dutch door provides additional ventilation control and easy access.
Attractive and Durable Redwood Frame.
The 2" x 2" clear grade, kiln 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, thus preserving old-growth redwood forests.
The frame base is 2" x 4" plastic lumber made of 100% recycled plastic. Its impervious to rot, mildew and insects and matches the redwood frames color.
No Foundation Required.
Exceptionally rigid and lightweight, only the corners of a GardenHouse need to be anchored to the ground.
Assembles Quickly and Easily.
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 3-6 hours to assemble. Even the 8' x 12' takes less than a day for a "non builder" to complete.
Strong-Tie® Connector System Provides Superior Strength and Durability.
Simpson Strong-Ties patented Rigid Tie' Connectors make this structure rigid and strong. The GardenHouse was tested by an independent lab and withstood their maximum wind load capacity of 85 miles per hour with no damage.
Efficient Roof System
The optimum 45º 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 18lb. per square foot.
Optional Benches.
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' model, which are 31" deep. They can be stacked to provide additional growing surface.
