Description

For the highest acoustic and thermal performance. Thermally broken extruded aluminium outer frame, face frame width 40 mm. Framed louvres set into thermally broken frames. Double glazed louvres with 28mm thick clear toughened, float or laminated glass. Glazing seals comprise double weather strips with a nylon lip between, and the horizontal glass edges of the louvres are enclosed with aluminium sections which have two overlapping weather seals for excellent air-tightness. Externally tested to and in compliance with EN 12101-2 as a smoke ventilator and CE marked. Externally tested to EN 14351-1, guaranteeing its performance as a façade element. Manufactured under the ISO 9001 quality and ISO 14001 environmental management standards.

Standard product features	Frames: Thermally broken, 47 mm deep. Glazing seals comprise double weather strips with a nylon lip between. The horizontal glass edges of the louvres are enclosed with aluminium sections which have two overlapping weather seals for excellent airtightness.
Product Options	Blade pitch: 155–355 mm (depending on overall size of complete unit) with central pivot point. Blade frame to be a maximum of 49 mm between glass surfaces. Visible width of horizontal louvre frame 32 mm when looking from the outside. Fixing: Fixing can be to curtain walling using 24–44 mm thermally broken glazing frame adaptor, or to structural opening using either through frame or strap fixings. Controls: Frame mounted and painted motor (hidden behind side frame profile) positioned at top or bottom on either side of frame and with a typical operation time of 32 s. Optional device to reduce force of closing louvres, to reduce the risk of finger squeezing (electric versions only). If used as a smoke ventilator, activation is either by local thermal fuse which opens the unit at a pre-selected temperature (pneumatic version only), or by responding to an external release signal. Its performance varies with size and options selected (tests to BS EN 12101-2 and BS EN 14351-1): Aerodynamic coefficient: Up to 0.58. Reliability: RE 1000 (10,000 cycles). Wind load: up to 3000 N/m². Snow load: SL 0. Resistance to heat: B300. Low ambient temperature operation: T(00) / T(-15). Materials resistance to fire: E (to BS EN 13501-1). U value: up to 1.46 W/m²K. Air permeability: Class 3 to BS EN 12207 – 1.89 m³/hr/m² or 0.37 m³/hr/m at 50 Pa. Watertightness: Class 4A to BS EN 12208 – Watertight at static pressure of up to and including 150 Pa. Sound insulation: 41 dB R’w.
