Acoustic Hermetically Sealed Sliding Doors
“You can hear the difference”
A sound choice for doors
Noise at Work Regulations 1989 requires sound levels to be maintained within clearly defined limits. But even below these parameters, noise can at the least constitute a nuisance and, at the worst, seriously affect health as well as the quality of life and work conditions.
markus acoustic doors have been designed and developed to offer the ideal solution by reducing noise to an acceptable level
These ultra-efficient doors provide access without compromising acoustic requirements controlling and excluding unwanted noise in a wide range of environments such as schools, hospitals, radio, television and recording studios, theatres, workshops, leisure centres, factories and test facilities.
Each markus acoustic sliding door is available in virtually every size, made-to-measure and finished to meet individual requirements.

AM5 type door comprises an insulated core whilst AM2 and AM10 models incorporate a range of composite acoustic panels which provide varying degrees of sound attenuation. All doors feature an independent acoustic framework and are offered in a choice of colours and finishes.
The VAM range offers an acoustic vertical sliding door.
A highly efficient hermetic sealing system incorporating a unique patented rail assembly is used on markus acoustic sliding doors. Suspended from an overhead track, the door closes flush onto the sill and locks positively to form an hermetic seal. This, combined with the special composition of the door blade provides exceptional smooth, silent operation and outstanding noise reduction qualities. Aluminium or stainless steel canopies are available.
- Horizontal or vertical opening doors.
- Manual and automated operation.
- Silent, easy operation.
- Superb sealing quality.
Even at large sizes, the smooth action of the markus rail enables the door to be moved easily by hand after initial opening. Aside from manual operation, the door can also be automated.
Continuously driven automation is also available on request, along with emergency opening facilities for use in the event of a power failure.
Silent opening requirements can also be provided for.
