ACOUSTIC SEALING
SYSTEMS FOR DOOR ASSEMBLIES
Sealing the gaps around a door is of prime importance when
reducing the amount of sound entering or leaving a room. Wherever noise
influences human activity, effective acoustic sealing is essential. We can
provide a wide range of acoustic seals that can be fitted to fire rated and
non-fire rated door assemblies that produce excellent resistance to airborne
sound.
On external doors they isolate buildings from noise generated
by roads, railways and airports. Fitted to internal doors they help to isolate
rooms from airborne noise generated within a building. Examples of use include:
auditoria, consultation and conference rooms, hotel bedrooms, offices and
individual homes in communal dwellings.
The
following information is for guidance only as the variation of door types,
thickness and density can have significant affects on the acoustic performances
you can achieve. The information has been summerised from the Lorient range of
products that are typically used for acoustic sealing.
