Acoustic / Non-Acoustic Louvre

Type ACL1 & ACL2 / Type ACLN

With the increasing need for quieter air conditioning systems, TEK manufacture acoustic louvres to meet the architects’ requirement of aesthetically pleasing looks while meeting the building services requirements for airflow and noise reduction. The louvres have been tested by an independent consultant to BS2750.

Because all louvres are designed and manufactured in-house by engineers with many years’ experience we are not restricted to standard sizes. This means each louvre is tailor-made to meet your opening dimensions. We offer a comprehensive service with our acoustic design which ensures you receive the best possible advice at planning stage, thereby avoiding site problems later on.

On large louvre assemblies/screens our engineers work in close liaison with you from quotation and design to order stage through manufacture to delivery and if required, organise our own experienced fitters.

Acoustic Louvre

The standard acoustic louvre is 300mm deep manufactured from 1mm thick galvanised mild steel up to a maximum size of 2400mm x 2400mm. Larger sizes are available made up in modules. Bird guard mesh is fitted as standard.

The louvres are supplied undrilled and are normally fixed through the sides by others. (Refer to fixing methods for other suggestions).

The standard double banked louvre is two single units back to back making th louvre 610mm deep manufactured from 1mm thick galvanised mild steel up to a maximum size of 2400mm x 2400mm. Larger sizes are available made up in modules. Bird guard mesh is fitted as standard.

As the single acoustic louvre.

The frame and blades are manufactured from 1mm thick galvanised mild steel or aluminium. Each blade in the airstream has an acoustic infill covered by 0.7mm thick perforated or expanded galvanised steel sheet. The blades are positioned on a 150mm pitch.

The infill is inorganic mineral wool or glass fibre rigid slabs with a glass fibre tissue face to limit fibre erosion. The fibre is inert, vermin, rot and moisture proof, non-combustible, non- supportive of bacteriological growth and packed to a density of not less than 45kg/m3.

The infill has been tested for fire and has a Class 1 spread of flame (as measured to BS476: Part 7: 1971).

There are no standard sizes for the acoustic louvres as each louvre is tailormade to meet your requirements. When specifying the size, we require the actual opening dimensions as we allow a tolerance to ensure the louvre fits into the opening.

The louvres have been tested in accordance with BS2750:1980 by an independent consultant.

The louvres have been tested in accordance with BS2750 by an independent consultant. See pressure loss charts.

As standard the louvres are supplied in gal- vanised mild steel finish but can be supplied with a polyester powder finish to BS4800 or RAL colours or a BSC Plastisol HP200 Finish.

Non-Acoustic Louvre

The non-acoustic louvre is normally used to match the appearance of the acoustic louvre. It is 150mm thick galvanised mild steel up to a maximum size of 2400mm x 2400mm. Larger sizes are available made up in modules.
