Polyethylene film greenhouses

Polyethylene film covered greenhouses have been developed so that they are reliable, and usually have a lower initial cost than most other greenhouse glazing systems. All plastic coverings are affected by weathering and have useful lives of 3-5 years for films, and 10-15 years for rigid panels. Low air infiltration rates resulting from the continuous film cover have improved energy savings, but contribute to high greenhouse air humidity conditions. Moisture condensation, especially on flattened arch-shaped roofs, promotes dripping on the crop below. The open-roof greenhouse structures, where the entire roof can be mechanically opopened and closed, have resolved some of these problems.

Residential Pool Enclosures

Garden Prairie enclosures are designed to give you a light, crisp garden environment, letting you enjoy summer activities all year, maximizing usage and guaranteeing a relaxing and enjoyable environment. This setting offers a dramatic surrounding for year-round swimming, whether it be lab swimming in the morning, children's entertainment center in the afternoon or relaxing dip for adults in the evening. The octagon end blends into the landscaping with the gable style end opening onto the patio, maximizing the entertainment area.
