Interaction of the Components


Sound insulation of building elements is accomplished by all components and requires precise modulation between them.

  • Joints between door and frame must be tightened with sealing gaskets without gaps.

  • All gaskets should be in-plane for exclusion of sound transmission through gaps.

  • Advanced acoustic requirements are managed with several sealing planes  forming circumferential chambers. Automatic dropseals have to be within these chambers, e.g. between two frame seals.

  • The bottom gap can be tighened with an automatic dropseal or a threshold stop. The threshold enables the formation of an in-plane seal, however other functions of the door element might be affected.





Influence of Joint Tightening


Overview

In a first step, the sound insulation value is determind for the fully caulked door. This value represents the maximum possible insulation. The door is not yet operable at this state.

The sound insulation value for the operational door correlates with the fully-caulked value minus the losses due to sound transmission through the door components.

Detailed determination of losses is done by stepwise removal of the sealing mastic. It allows precise analysis of sound losses at the particular components for the optimisation of choice and installation of the components. The design of the door edge, the seal type and its allocation influence the result essentially.
