Parallel Opening Vents

Parallel window openers can be used to optimise natural ventilation and air exchange without compromising safety and security. With this type of system, fresh air is drawn in via the bottom and side of the vent, while stale air is expelled via the top. Our Parallel window control systems are ideal for use in curtain wall facades or high rise commercial buildings.

Manual Window Control Uses

Manual Window Controls are used widely throughout the Education, Social Housing and Residential sectors, though we have recently introduced a new range of Window Openers specifically geared towards the Home Improvement & Domestic market place.

In the Social Housing sector, we install Manual Window Controls (openers or actuators, closures as well as manual window restrictors and Teleflex winding gears) adapting properties and aiding the elderly or the less able to ventilate their properties and easily open those hard to reach windows.

The majority of our Manual Window Controls are installed within the Education sector. From operating high level vents in school halls to classroom windows, our systems can operate single or multiple vents, providing a comfortable classroom temperature as well as the benefits of natural ventilation.

Within the Commercial sector, our Manual Window Controls (including openers, closures, actuators, restrictors and Teleflex winding gears) are widely used in factories, print works, atria or other industrial applications. At Pratley & Partners our 50 years of window control experience enables us to adapt systems if necessary.

Our bespoke systems have been installed within the Thames Barrier, Buckingham Palace and the BT Tower.
