Algoma’s Acoustical doors were tested
as operating units in a complete system
with hollow metal framing back-filled
with mortar, gasketing, drop seal and
threshold, where applicable — the
same as supplied to the jobsite — thus
ensuring that the specified STC ratings
are achieved.
Sound Transmission Class (STC)
40 Acoustical doors should be used
wherever the degree of sound
insulation desired is higher than an
ordinary solid core door can provide.
If a still higher degree of sound
reduction is required, such as in
hospitals, doctors’ offices or conference
rooms, the STC 45 Acoustical door may
be specified.STC 43 Acoustical doors
are available for openings which require
both sound control and 1/3-hour fire
ratings.
When job requirements include doors
with glass openings, STC 39 Acoustical
doors are available, non-labeled.
And for communicating doors, a STC-
54 rating is achieved when two STC-40
Acoustical doors are installed back-to-
back in the same opening.
Testing was conducted by Riverbank
Acoustical Laboratories in accordance
with ASTM E90-90 and E413-87.
