Coltlite for Glass louvre - natural glass louvred ventilator
General description
Coltlite is a natural louvred ventilator for installation into the façade for both day to day and smoke ventilation. It is available in a wide range of sizes, louvre options and control options.
Its form and function make it particularly suited to naturally ventilated buildings where good aerodynamic and measured free area ventilation is required while achieving high acoustic, thermal and aerodynamic performance. Whilst it is primarily designed as a glazed element of the building envelope, it can also be applied as a high specification fire, smoke and air control damper. Typical applications are hospitals, schools, apartments and commercial buildings.
Coltlite louvred ventilators are popular with Specifiers and Contractors because of the wide range of options available, and with Building Operators and Owners because of their simplicity and low maintenance.
Natural ventilation is an energy-efficient means of reducing the effects of excessive temperatures. Hot air can leave through the ventilator at high level, and fresh air be introduced at low level.

Generic Options
Dimensions - Depending on the version selected, overall widths are available from 250mm to 1800mm overall frame width, and from 200mm to 3000mm overall frame height as one module. See detailed specifications by clicking on one of the above links.
Louvres - Glass louvres are manufactured as standard in single and double glazed options. There is the choice of glass with a thickness of between 4 - 8 mm for the double glazed systems, with an overall glass thickness of 32mm, and glass with a thickness of between 8, 10 and 12 mm for the single glazed version. A version is also available with double louvres that sit completely flush with the facade. Louvres can also be provided with insulated aluminium sections.
Frames - Outer and louvre frames are available either thermally or non- thermally broken.
Controls - Coltlite is available with pneumatic, hand, 230v ac or 24v dc electric controls for the potential to be connected to a building management system.
With the electric version, at the flick of a switch a Coltlite ventilator moves noiselessly to any position, automatically stopping at the fully open and fully closed positions. Alternatively, blades can be stopped in any intermediate position throughout the duration of the open/close cycle. Coltlite has an anti-finger trapping facility.
Hand controls include lever handle or crank handle with window winder.
Paint finishes - Coltlite is available mill finish, anodised or polyester powder coated to a RAL colour. Thermally broken frames can be coated to different colours inside and out.
Installation - The ventilator is designed for installation in the vertical only into fully drained glazing systems or structural openings.
Features and benefits
Wide range of applications - Coltlite is designed as a dual purpose ventilator, providing both day to day and smoke control ventilation. The units can be supplied in either non thermally or thermally broken frames with single or double glazed assemblies. There are pneumatic, electric or hand controls and a wide range of frame types, louvre types and finishes.
High performance - Coltlite is aerodynamically efficient, has a low U value, is exceptionally airtight and has a high resistance to weather. Its free area is approximately 3 times that of a bottom hung ventilator of a similar size. Please see the leaflet (pages 6-7) for further details.
Proven performance - The majority of Coltlite ventilators have been tested to and are CE marked in accordance with EN 12101-2 in accredited third test laboratories.
Discreet appearance - Coltlite only projects a small way into the surrounding space. It has a narrow perimeter frame which can be easily integrated into glazing systems or into solid structures. One version can accommodate a hidden actuator.
Easy to install - Coltlite delivered fully assembled to site. It has a wide range of adaptor profiles to suit its vertical installation into curtain walling, glazing or prepared openings.
Efficient operation - When Coltlite ventilators are connected to a building management system, they can operate automatically without any human intervention. A single actuator is capable of operating a large number of louvres on its own thereby reducing wiring costs. It is possible to modulate the louvre positions to any intermediate angle between the fully open and fully closed positions.
Safe in operation - Coltlite has an anti-finger trapping facility.
Durable - Coltlite is manufactured from extruded aluminium frames and precision engineered aluminium pivots.
Quality of manufacture - Each Coltlite unit is given a functional test before despatch.
Low maintenance - Coltlite units are very low in maintenance requirements.
Design service - Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of Coltlite.
