Siderise WRX | Window Reveal Liner – Technical Data

Version: 2.00 - Release Date: September 2018

Application

Siderise WRX Window Reveal Liners provide a practical means of improving the sound insulation performance of secondary glazed windows.

Their application to the reveals substantially reduces the reverberant sound field in the void formed between the primary and secondary glazing.

Product Description

Siderise WRX Window Reveal Liners comprise an absorptive core of dense rock-fibre insulation held within a covering of perforated sheet metal, which is formed around the sides and top of the core.

The dense rockfibre core is of a special construction to provide improved impact resistance. As standard the core is faced on both surfaces with a non-woven glass fabric to provide anti-dusting characteristics whilst remaining acoustically transparent.

The perforated metal covering is normally finished by either polyester powder coating or for aluminium versions by anodising as required.

Where the end of the installed liner would not normally be hidden, such as at corner junctions or for long reveals as butt joints, the metal covering is additionally formed over the end of the liner to provide a neat final appearance.

Acoustic Performance

The sound reduction performance of a secondary glazed window is increased by the application of a sound absorptive material to the reveals.

The level of improvement is influence by a number of factors.

Two of particular significance are:

The ratio of the treatment area to the total internal surface area of the window void
The sound absorption coefficient of the applied liner.

The sound absorption characteristics of Siderise WRX Window Reveal Liners alters with the liner thickness and the method of mounting e.g. direct to a solid background or suspended above a cavity. Our technical department can provide indicative adsorption data for the specific arrangement under consideration.

Typically the improvement in the SRI (mean Sound Reduction Index) of the window is in the range 2 - 4 dB.
