Doorsets are supplied with all the necessary seals fitted to
either door or frame, sometimes including astragals for pairs.
With acoustic doors the gap between door and threshold
on the floor must also be sealed with drop seals and/or
thresholds, depending on performance requirements and
floor finish. Special care is needed to check that doors close
correctly all around, noting a slight resistance when the door
closes against its seals.
- A level floor is essential to threshold sealing
- Seal under the threshold and bottom of jambs, as well as back of frame
|
 |
- Plumb square and level to ensure that seals contact fully all around
- Seals must not be cut for ironmongery
- Never paint seals or close a freshly painted door onto them
- Avoid damaging all seals, particularly on the bottom edge
Best practice on site is critical, sound is like water in that all
gaps must be properly sealed to stop leakage.
