R+T Middle East 2010 showcased the latest trends and developments in roller shutters, doors and sun-protection systems, with a strong emphasis on energy-saving measures.

The latest trend in roller blinds, metallic fabrics, can slash the electricity consumption of an air-con system in a typical building by at least 50%, says TechnoShade LLC manager Mohammed Imtiaz. "These kinds of products create a very high reflectance of solar radiation, and therefore a much lower G-value, so that less heat enters a building."

The harsh climatic conditions in the Middle East have boosted the demand for environment-friendly roller shutters and sun-protection systems, says Alusol GM Nasser B. Al-Essa, one of the exhibitors at R+T Middle East 2010.

"This, in turn, has created a demand for better solutions that use innovative new technologies that provide the best protection against the heat and dust in the region," says Al-Essa. For example, Alusol rolling shutters are insulated against 70˚C. Established in 2006, the Kuwaiti company is the only rolling shutter manufacturer in the GCC, and has hence become an established brand in the region.

"The demand for rolling shutters is strongest in the residential sector at present, with an increased demand for affordable housing projects, particularly in such countries as Saudi Arabia, Qatar and Bahrain," says Al-Essa. An example of a current commercial project demanding rolling shutters is the Awtad Real Estate Company's expansion of the Al-Jahra Shopping Mall in Kuwait.

Another company hoping to bring its innovative technology to bear on the region's particular climatic demands is Temperance, a French manufacturer of solar glare, reflection and heat control systems. Export manager Alain Huck says this is the company's first foray into the Middle East, where the modern architectural trend is for wide glass surfaces.

"The thermal screen in our roll blind system for glass frames provides more effective protection against the sun than an external system," says Huck. In addition, having an internal sun-protection system obviates wind damage and maintenance requirements due to dust.

"Rolosun is adaptable to either new or renovated windows, and fits either wood, PVC or aluminium frames. It can be set up in the frame itself or in the splay. The system is fixed by means of only two angle brackets, or directly on guide rails. Due to an exclusive process to stretch and guide the metallic film, Rolosun blinds work horizontally as well as vertically. They can fit all shapes and sizes, including rectangular, triangular, curved or trapezoidal and straight or inclined windows," explains Huck.

Rolowin, on the other hand, is an integrated blind solution combining thermal insulation with solar protection. "Essentially it is solar blinds between insulating double glazing," says Huck.

"Best thermal results are obtained with a cavity width of 16 mm, the standard for double glazing. In addition, Rolowin adapts to all kind of window frames and all façade styles, whether new build or renovation. Another plus factor is that it needs no maintenance."

FEIG Electronic GmbH showcased controllers for high-speed doors boasting integrated frequency converters. "The integration of frequency converters for controlling the motor speed of electronic doors has many advantages, in particular mechanical protection," says sales manager Hans-Joachim Burle.

The company specialises in contactless identification (RFID), door controllers and traffic sensor technology. "As far as the MENA market is concerned, ‘green' products are very much in demand.

Due to the high external temperatures, there is a need for high-speed door controllers that can help slash the energy demand associated with the cooling load," says Burle. FAAC Middle East showcased "a new series of products that enables the advantages of automatic operation to be extended to rolling shutters and sun blinds," says T-MODE sales manager Alessandro Zanetti. The TMS35 range of Ø 35 mm tubular motors, for example, are suited to rolling shutters, screens and vertical screens.

Features include mechanical and electronic limit switches, with adjustment possible via remote control. A range of accessories is also available, including adaptors, support brackets, remote controls, programmable timers, sun and wind sensors and external receivers.
