Fieger Louvre Window – Type Smotec

The Smotec model represents the culmination of development work on both the FGL and FLW louvred window units. This is a fully certified natural smoke & heat exhaust ventilator (NSHEV), having been tested to all relevant categories under EN 12101-2: 2003.

As a CE marked product, it meets the legislative requirements of Approved Document B (UK Building Regulations) to provide façade smoke venting to stairwells, lobbies and corridors in order to assist escape.

Our production quality control, under which every ventilator has an operational check prior to despatch, ensures that each consignment is fit for purpose.

A key advantage of the Smotec is the large open free area it provides, which, of course, is critical for emergency smoke control. As a result of its carefully engineered design, and thorough development testing, the Fieger Smotec achieves a high coefficient of opening (Cv). The Cv ranges from 0.57 to 0.61, depending upon overall dimensions and aspect ratio.

It comprises thermally-broken framework, which houses our patented rack & pinion mechanism. This drives the louvres to ensure synchronised, maintenance-free operation.

The glass louvres are housed in thermally-broken extruded aluminium frames and incorporate pivot bearings to connect to the rack & pinion mechanism.

The louvres are centre pivoted, which means that an optimum free area of ventilation can be achieved – an opening angle of 85 degrees provides a better free area than a traditional window. The rack & pinion mechanism also ensures that a good compression seal is achieved when closing the louvres. This provides a particularly important benefit in minimising air leakage.

The louvres are available as either 24mm or 28mm double-glazed insulated blades or 8mm to 12mm single-glazed and can be configured to suit a variety of opening sizes and applications. Insulated aluminium blades can also be supplied.

The FLW can be supplied complete with a range of fixing adaptors, to facilitate installation into brickwork, curtain walling & glazing. We can meet specific requirements across a range of sizes, colour finishes and glass specifications.

The FLW range complies with The Building Regulations in the UK and specifically Approved Document B: Fire Safety, Approved Document L: Conservation of Fuel and Power and Approved Document N: Glazing – Safety in relation to impact, opening and cleaning.
