Usually, the system type we used for this project has the rolling shaft mounted on the side of the house. However due to the hand folded zinc cladding on the house, this was not possible as the cladding is very hard to modify once installed and is a very expensive to replace if damaged. To avoid any damage to the cladding we redesigned the system to be free-standing on 4 poles.
In order to integrate the poles into the existing decking we needed to carefully cut the decking timber to fit around our tear shaped poles and engineer plates to fit around the base of the poles on the deck.
A unique feature of this project is the ground screws we used instead of concrete foundations. The ground screws are drilled into the ground and our poles slot in and are fixed ensuring no movement when the sail is opened and retracted. They can be easily removed should the system need to be moved or taken down for any reason and reduce the carbon footprint of the project by avoiding the use of concrete. We used the ground screws for all 4 pole foundations.
Operated by a Smart Phone App and Wind sensor, the user can set a range of “rules” for the sail’s opening and closing sequences, such as day/time, wind speed and the level of sunlight, along with being able to control the system remotely at any time.
