Mounted in façades and end of corridors, Façade Louvre Blade – Residential (FLB-R) smoke vents exhaust smoke and heat from a building allowing escape routes to be kept clear of smoke and are fully certified to BS EN12101-2. They may also offer inlet air and comfort ventilation. They are available in a wide range of louvre glazing options and control systems and are particularly suited to apartments and commercial buildings. They are fitted with an anti-trapping actuator which protects from injury and offers high resistance to weather and is therefore suited for use on exposed and high wind areas. They provide good security and do not create a fall hazard when open.
The FLB-R louvre incorporates a thermally broken aluminium framework. The frame sections are 40mm wide and 77mm deep, with mitre joints and are manufactured from thermally broken aluminium. All aluminium is polyester powder coated to a standard RAL colour. Glazing options include a 30mm thick toughened inner/ laminated outer double glazed blades with argon filled cavity and warm edge spacer; or triple glazed for increased U-value.
Alternatively, they are available as solid insulated blades which may be mill finish aluminium or powder coated to any RAL colour. They are installed vertically and available with a wide range of adaptors for installation into refurbishment situations as well as new build. The actuators are 24V DC, 1.2 Amps, and mounted on the internal top right hand and have a traction force of 1400N and with an IP20 protection rating. They are supplied as standard with a built-in anti-trapping feature for protection against injury. They consume minimal energy during opening and closing.
The values are calculated centre pane U-values unless denoted otherwise. However, complete unit U-values are available on request.
