  • Glass Louvres

    Glass Louvres

    In the glass louvre range we still offer the traditional Naco Standard louvre and Weatherbeta single glazed framed louvre for export markets while for the UK and Europe our VenGen 28 double glazed thermal break glass louvre has established market leading acceptance for a new generation of louvre systems. They are joined by our Nacoscreen system which acts as a chill/heat barrier in front of primary glazing. Our louvres are offered with various operation options from automatically opening windows through to our Smokebeta control units.

    Weatherbeta Louvre

    Naco’s architectural range of single glazed louvres is well established in many parts of the world and applications include high tech buildings, hospitals, universities, domestic dwellings and sheltered accommodation.

    Weatherbeta is an elegant quality engineered product which combines a strong aluminium frame system with ventilating blade holders produced from precision injection moulded polypropylene material.

    NEW DB50 Storm Louvre

    Naco has launched a new range of storm louvres providing the highest level of weather protection for buildings and plant in a shallower profile to ease fitting in a wide range of applications.

    The DB50 range meets the most stringent test criteria for wind driven rain protection and provides ideal pressure drop performance all within a shallow 51mm extruded aluminium frame that eases fitting in narrow window units and other restricted wall spaces.

    The optimum blade pitch minimises the penetration of wind-driven rain, reducing damage and additional operating expenses. The use of extruded aluminium reduces maintenance costs and provides high resistance to corrosion.

    Also, because it is such a slim unit it is quicker and cheaper to manufacture so making it one of the most competitive products on the market, but without any compromise on performance.

    The new DB50 has been stringently tested to meet standards set by the industry’s international body the Air Movement and Control Association (AMCA). Naco’s louvres have passed AMCA’s 500-L Wind-Driven Rain Penetration test and the performance specifications are verified by the association’s Publication 511.

  • Mist Separators

    We also have a presence in the luxury boat building marketplace where we sell our mist separator, based on our vertical blade louvre, which is used for air intake applications. Vertical blade mist separators are used for air intake applications where high air volumes are required coupled with the necessity for removing sea spray / salt from the air intake
    system. Mist separators may be fitted behind decorative grilles or as the prime unit. Horizontal blade units are also available, where, for aesthetic reasons, a horizontal line is preferred.

  • Sunscreens/Brise Soleil

    We offer simple Z blade fixed screens together with a range of ellipsoid blades some of which may be fixed or adjustable. Ellipsoid blades are used for both horizontal screens above windows or for vertical screens in front of windows. Sunscreens continue to be popular for many applications in commercial buildings, meeting the needs for control of solar gain and energy conservation while offering designers a palette of possible effects within the external cladding. A new brochure is available illustrating our full range of sunscreen products. The brochure also contains information on a range of standard screen types for easy selection by specifiers together with blade span charts for our ellipsoid range.

  • Natural Air Ventilators NAV Units

    Naco’s natural air ventilators have been developed for schools and similar buildings where controlled fresh air inlet is required. The system is flexible and enables any of the Naco range of metal louvres to be used in conjunction with insulated, aluminium or plastic blade dampers and caters for virtually any combination of height and width sizes.

    While openable windows offer primary ventilation, it is often difficult to use them due to draughts, rain, cold and noise issues. Roof mounted air systems often rely on wind and wind direction, therefore while they offer some opportunity for air intake and extraction at high level, many leading designers are introducing low level natural air ventilators (NAVs) at or below window level, the purpose of which is to control ventilation (to ensure an adequate supply) and so prevent build up of carbon dioxide during the day. These natural air ventilators normally comprise of an external louvre for weather protection and an internal electrically controlled damper, linked to the BMS. Another benefit of NAVs is their use in nighttime cooling systems as they do provide security against building entry.
