AL-OV-R

The AL-OV-R is an acoustic attenuating mat that has been designed to provide acoustic attenuation when used in conjunction with the OV-R wall transfer unit. It is made from polymer foam which has high noise-attenuating properties. Before the installation of the OV-R, the AL-OV-R acoustic attenuating mat is simply rolled and inserted into the wall opening and lines the inner surface of the opening. 

For walls less than 150 mm thick, the mat can be cut to the length corresponding to the wall thickness. For walls that are thicker than 150 mm, an additional mat can be ordered as an accessory. Two mats can be combined and cut to the corresponding length to line the entire inner area of the wall opening.
