A retractable roof is a roof system designed to roll back the roof of a structure so that the interior of the facility is open to the outdoors. [1] Retractable roofs are sometimes referred to as operable roofs or retractable skylights. The term operable skylight, while quite similar, refers to a skylight that opens on a hinge, rather than on a ...
Cheaper than slate or tiles. The reduced cost of this particular style of roofing is especially apparent in its application and removal. Installation is very streamlined and a rapid process. Depending on the size of the roof and the experience of the crew, it is possible to remove old shingles and apply new ones on 2-3 houses in one day.
The nesting of row covers and low tunnels inside high tunnels is also common. [1] Superbay Polytunnel at Van Arnham Nurseries. Polytunnels can be used to provide a higher temperature and/or humidity than that which is available in the environment but can also protect crops from intense heat, bright sunlight, winds, hailstones, and cold waves.
Retractable patio cover systems are the latest "entry" in to the retractable market. Most of these systems are water-proof as compared to water-resistant (lateral arm awnings) and therefore allow no water penetration through the fabric "roof" section. These systems meet Beaufort scale wind loads up to Beaufort 10 (89–101 km/h or 48–55 kn or ...
The retractable roof was designed by structural engineering firm Walter P Moore and the systems were implemented by mechanization consultants Uni-Systems. The electrification of Cowboys Stadium's retractable roof was developed by VAHLE, Inc. [ 26 ] These kinetic architecture fundamentals are employed to create quick conversions of the facility ...
The tunnel, which will be 18 kilometers (11.1 miles) long, is one of Europe’s largest infrastructure projects, with a construction budget of over 7 billion euros ($7.1 billion).
The Utility Tunnels in Qatar built on the Lusail, 15 km north of Doha, is approximately 14–15 km in length.

Flashing is thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier system. In modern buildings, flashing is intended to decrease water penetration at objects such as chimneys , vent pipes, walls, windows and door openings to make buildings more durable ...
