Paragon Outdoor Presents The Siena Gazebo

The Siena Aluminum Patio Gazebo is a durable and beautiful gazebo kit. It has an aluminum frame with aluminum composite panels that are architectural grade material. These panels provides insulation, noise reduction, and are rust resistant. Despite its size, the Siena is designed for easy assembly. One of the fantastic features of this gazebo is the sliding screen doors on all four sides! This gazebo literally becomes a screen house! Forget about any mosquitos or other bugs getting in. Two people can have this gazebo built in half a day, letting you enjoy spending the weekend relaxing beneath it. It comes with an easy to read the instruction manual. Hardware to bolt this gazebo to a concrete slab or wooden deck are included. Ground stakes are provided.

This rugged gazebo is made of aluminum and steel. The vertical posts are aluminum, and the rails holding up the roof are aluminum with steel inserts for strength. Base plates at the bottom of each post that the gazebo sits on are made of steel.

The Siena Screen Room has sliding screen doors on all 4 sides. Not only do they keep the unwanted bugs out, they act as a shield from the setting sun reducing the glare so you can enjoy your end of day.

The dome shaped roof is a sophisticated composite of layers of aluminum and polyethylene core, and multiple layers of finishes and coatings. The underside has a white-cream color finish that adds a wonderful glow during the day and into the evenings. Even candlelight reflects back down and illuminates the area at nighttime.
