The Siena hard-top screen room gazebo by Paragon Outdoor is the perfect way to luxuriate in your surroundings without the nuisance of bugs; boasting an elegant dome-shaped roof and sliding anti-insect screens on all four sides. The composite roof is constructed from multiple layers of aluminum with a polyethylene core to dampen sound during downpours and aid cooling during the hottest days. Its underside has an attractive cream finish to reflect soft lighting in the evening. The structure itself is made from powder coated aluminum which all but removes the need for maintenance due to its prevention of rust, while steel is used in places for added strength. Choose your preferred size from the three available and choose where you want to site it on your property, whether that’s on concrete, by the pool, on a patio or even on the ground itself and use the included hardware to secure it in place securely. Assembly requires no specialist skills and should take two adults around seven hours to complete. Shipping is free and the warranty terms are generous, so you can buy with complete confidence. Let the Siena become the centerpiece of your backyard and share timeless moments with your friends and family for years to come.
