Norsound Drop Seals for Different Installations
A door relies on effective sealing at the threshold to perform as intended. Gaps beneath the door allow sound to pass through and reduce the effectiveness of smoke control. The Norseal Norsound range addresses this with automatic drop down seals that create a controlled seal at the bottom of the door while allowing smooth operation.
They offer flexibility across different door types and site conditions:
- Rebated and surface mounted options available
- Suitable for both new installations and retrofit work
- Supports acoustic and smoke sealing at the threshold
- Tested for compliance to relevant standards
- Designed for reliable operation in high use environments
Within this range, the NOR810 and NOR820 cover two common installation requirements.
NOR810 Rebated Drop Seal
The NOR810 is a rebated automatic drop seal fitted into the bottom edge of the door. It provides a concealed finish and suits applications where a hidden seal is preferred. This makes it well suited to acoustic timber doors where appearance and sealing performance are both important.
NOR820 Surface Mounted Drop Seal
The NOR820 is a surface mounted drop seal fixed to the face of the door. It is suited to applications where morticing is not practical or where maintaining the original door construction is important. This makes it a practical option for retrofit work, pre-finished doors, and installations where the door cannot be machined.
Door Sealing for Your Built Environment
A well selected seal improves how a door performs in real conditions, especially where both sound control and smoke containment are required. Explore the Norseal range today to find the right drop seal for your door.
