FIEGER Ltd. - FIEGER Louvre Window – Type FLW 32

The FLW 32 is a CE marked double-glazed louvred ventilator, which has been carefully engineered to produce a class-leading product.

It comprises thermally-broken framework to reduce heat loss and avoid condensation; a requisite feature to ensure compliance with UK Building Regulations.

The frame houses our patented rack & pinion mechanism, which drives the louvres to ensure smooth, maintenance-free operation. Combined with a wide choice of actuators, this makes the FLW 32 a highly versatile unit.

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

The pinion design has been enhanced to minimise vandalism.

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.

As a result of thorough development testing, the FLW 32 achieves a high coefficient of opening; up to 0.58, subject to size and aspect ratio.

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 FLW 32 is rated as Class 4 (200 Pa) in accordance with EN 12207.

It is also certified as Class 5A under the EN 12208 Watertightness test.

The SmoTec version of the FLW has been fully tested and certified under EN 12101-2 as a natural smoke & heat exhaust ventilator (NSHEV).

The AirTec model is certified in accordance with EN 14351-1 Windows and doors – product standard.

The model has also been barrier-load tested to BS 6180:2011.

Airborne sound insulation testing has been carried out to ISO 10140-2, with a sound reduction of 40 dB recorded for double-glazing.

The louvres are available as either 28 mm or 32 mm double-glazed or triple-glazed blades and can be configured to suit a variety of opening sizes and applications.

Insulated aluminium blades can also be supplied using either expanded polyurethane foam or mineral wool.

A range of actuators is available as standard, including 230 volt AC or 24 volt DC motor drives as well as pneumatic cylinders. Manual operation is provided by a handle fixed to the frame or a crankhandle, which can be either fixed or detachable.

Where necessary, a motorised version can be provided, which is programmed to avoid finger-trapping.

Drives compatible for BMS interlink can also be supplied.

The FLW 32 can be supplied 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.

Typical glazing specifications include:

Toughened outer safety glass, an Argon filled cavity and laminated Low-E inner glass.

Float and solar reflective glass can also be provided as standard, whilst special glazing can be provided on request.

The FLW 32 complies with The Building Regulations in the UK and specifically:

Approved Document B: Fire Safety

Approved Document K: Protection from falling, collision and impact

Approved Document L: Conservation of Fuel and Power

Approved Document Q: Security – Dwellings

Its use can also contribute to BREEAM assessments.
