8 Customizable, Changeable Configurations

As with all Krieger products, the Acoustical Door and Window Wall Assembly can be configured to your exact specifications of size, number and placement of doors and windows and acoustical needs.

Mullion or Astragal
Door pairs come with either a mullion or astragal to seal the gap between the doors when they are closed.

Changeable
Plus, the way it’s construction makes it possible to swap out the doors, glass panels, and mullion or astragal components in case your needs change later on.

Easier Installation
The perimeter and mullion sections of the Acoustical Door and Window Wall Assembly are filled with rock wool material for sound control instead of heavy grouting compound. Rock wool makes the unit much lighter weight—and, which makes installation faster and easier.

In addition, Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style.
Fire Rated Up to 90 Minutes
Most other wall unit products are not fire rated, but Krieger’s Acoustical Door and Window Wall Assembly comes with a fire label and is fire rated up to 90 minutes with glazing, or up to 3 hours with acoustical transom or side lite panels.

The acoustical seal can also block in air and actually help regulate temperature and control smoke.
