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.
Where pairs are required a slight reduction in performance can be expected from the single leaf value. Overpanels, side panels, fanlights and sidelights are also available. Double action assemblies 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 certain 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 (threshold arrangement C) is available upon request 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 fully sealed glazing beads. Glazing generally has a lower acoustic performance than the door (maximum 40RwdB) 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.
