Coltlite at Aboriginal Centre, Sydney
Coltlite is a natural louvred ventilator for installation into the façade for both day to day and smoke ventilation. It can provide an elegant means of providing ventilation.
Its form and function makes 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, shopping centres, apartments and commercial buildings.

Features & Benefits
Wide range of applications – Most versions of Coltlite are classed as dual purpose ventilators, providing both day to day and smoke control ventilation. It can also be installed either for low level air inlet or for high level extract. Coltlite is also often used as a termination piece for large ducted or air handling systems. Glass versions allow the entry of natural daylight, and a wide range of infill panels are available. Options include pneumatic, electronic or manual controls and a wide range of louvre types, accessories and finishes.
High performance - Coltlite has high aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire. See the leaflet for further details.
Certified performance – Most versions of Coltlite have been exhaustively tested and certified to EN 12101-2: 2003 as dual purpose ventilators in accredited third party test laboratories and are CE marked. The ventilator is CE marked according to EN 14351-1 which guarantees its performance as a window.
High performance in fire - One of the architect’s main design considerations is to make sure that any smoke emitted by a fire is evacuated from the building in a controlled fashion. Special arrangements need to be considered, in particular for escape routes such as in stairwells. Coltlites are very suitable for protecting escape routes since they have a high aerodynamic efficiency, open quickly, have large openings and do not get in the way of people trying to leave the building.
Easy to install - Coltlite is delivered fully assembled to site into a structural opening or curtain walling. It must be installed in the vertical. It has a wide range of base profiles to suit most sheeting, curb or glazing applications.
Durable – The frame is manufactured from tough, corrosion resistant aluminium alloy, with stainless steel fixings.
Quality of manufacture - Coltlite is manufactured under the ISO 9000 quality standard. Each unit is given a functional test before despatch.
Aesthetic design – Coltlite uses narrow framework and motors can be hidden within the frame or are small in size.
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.
