Acoustic doorsets and performance
The table above summarises the various products available in the
acoustic doorset range, related to performance and other
characteristics, to assist with doorset selection to meet your
particular needs.
Configurations
|
The tested values shown in the table above relate to single leaf,
latched doors.Double leaf pairs are available as described later, with
square meeting stiles and surface astragals where necessary.
A slight reduction in performance can be expected from the single
leaf value. Overpanels, side panels, fanlights and sidelights are also
available. Double action pairs cannot provide high levels of acoustic
performance.
Square meeting stiles with surface astragals |
Frames and architraves
| The Barum frame section (supplied with architraves where
specified) is provided as standard for all acoustic doorsets.
The Cubith section can be used with some doorsets as indicated
on frame/seal arrangements on-site. Frame materials for each doorset and seal
arrangements are also shown. |

Thresholds
Low-profile aluminium thresholds are supplied with all acoustic
doorsets, in two arrangements A and B, as shown on frame/seal arrangements on-site, depending upon performance. They must be
installed level with the door and 5mm above the top of the
floor finish to ensure correct sealing when the door is closed.
For soft floor finishes, a hardwood packer may be needed
below the threshold as shown. An option for automatic drop
seals is available for 32RwdB. Further advice should be sought
from our Technical Services Department.
Vision panels
Acoustic doorsets can accommodate many of our standard vision
panel designs - all factory glazed (with glass to suit acoustic and fire
performance) using a fully sealed glazing beads. Glazing generally
has a lower acoustic performance than the door and will reduce
overall performance, directly in proportion to the amount of glazing
used. It is therefore recommended to minimise glazing in acoustic
doorsets. Contact our Technical Services Department to discuss
your design requirements.
