Coltlite natural louvred ventilator

Coltlite is a natural louvred ventilator suitable for natural day-to-day building ventilation, as well as smoke control. Most variants conform to both EN 12101-2 as smoke ventilators and EN 14351-1 as natural ventilators. All products are CE marked. It can provide inlet and extract ventilation as well as the entry of natural daylight for most kinds of industrial and commercial buildings. It achieves high acoustic, thermal and aerodynamic performance. It is suited for installation into the façade.

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 and benefits

A 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 – All versions of Coltlite except CLS 45 and CLST have been exhaustively tested and certified to EN 12101-2: 2003 as dual purpose ventilators in accredited third party test laboratories. In addition all ventilators have been tested to EN 14351-1 which guarantees their performance as façade elements. All ventilators are CE marked accordingly.

High performance in fire - One of the fire consultant’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.  Coltlite is very suitable for protecting escape routes since it has a high aerodynamic efficiency, opens quickly, has large openings and does 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.

Safe in operation – With electric versions there is an optional device to reduce the speed and force of the closing louvres in order to reduce the risk of finger trapping.

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.
