Kameleon natural casement ventilator

Kameleon 5 glazed natural casement ventilator, suitable both for day to day and smoke ventilation through the façade. Both flap and base frames have thermal breaks. It is particularly suited for installation into glazing systems. Kameleon conforms to EN 12101-2 and EN 14351-1 and is CE marked. For vertical installation only. It is manufactured under the ISO 9001 quality standard.

Product information

Kameleon 5 is a thermally broken glazed natural casement ventilator for installation into the vertical for both day to day and smoke ventilation.

Its form and function makes it particularly suited to naturally ventilated buildings where high acoustic, thermal and aerodynamic performance is required. Typical applications are hospitals, schools, shopping centres, apartments and commercial buildings.

Features and benefits

A wide range of applications – Kameleon 5 is classed as a dual purpose ventilator, 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. Glass versions allow the entry of natural daylight, and a wide range of infill panels are available. Options include pneumatic or electronic controls, as well as a variety of finishes. There are two different flap profile types, depending on the required appearance and performance of the ventilator.

High performance - Kameleon 5 has high aerodynamic, acoustic and thermal performance, and also has a high resistance to the effects of fire. Both flap and base frames have thermal breaks. See the product options page for further details.

Proven performance – All versions of Kameleon 5 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 also CE marked to EN 14351-1, which guarantees its performance as a façade element.

High performance in a fire – Kameleon 5 is very suitable for protecting escape routes in places such as stairwells where it can act as an automatically opening ventilator (AOV), since it has high aerodynamic efficiency, opens quickly, and has a large opening.

Easy to install - Kameleon 5 is delivered fully assembled to site for installation into a structural opening or curtain walling. It must be installed in the vertical.

Durable – The frame is manufactured from tough, corrosion resistant aluminium alloy, with stainless steel fixings.

Quality of manufacture - Kameleon 5 is manufactured under the ISO 9001 quality standard. Each unit is given a functional test before despatch.

Aesthetic design – Kameleon 5 uses a narrow framework. Electric actuators or pneumatic cylinders can be hidden within the frame and are anyway small in size.
