Acoustical Door and Window Wall Assembly
Highest Tested Acoustical Assembly of Its Kind—up to STC 52
Krieger's new Acoustical Door and Window Wall Assembly is fully customizable and is ideal for a wide range of interior and exterior applications, including industrial plant noise reduction, office buildings, meeting rooms, and schools.
Lab Tested as a Unit
Unlike other manufactures that test various door and window components separately, Krieger's Acoustical Door and Window Wall Assembly underwent rigorous lab testing—in multiple configurations, testing higher than any other wall unit on the market.

The benefits of being tested as a unit include:
  • Testing for sound loss due to splices in large areas
  • Guaranteed to achieve the desired STC rating
  • Strengthened reproducibility in the field
Lowest Frequency Loss
The Acoustical Door and Window Wall Assembly NVLAP accredited laboratory acoustical test reports demonstrate that our designs have industry-leading transmission loss between the 63 HZ to 125 Hz frequencies, with no deficiencies measured at greater than 95% confidence in dB.

The Acoustical Door and Window Wall Assembly low-frequency performance is best-in-class, making it the ideal choice for locations exposed to noise.
Customizable, Changeable Configuration
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. The construction makes it possible to swap out the doors, panels, transoms, and side light components in case your needs change.
Performance Combinations
Krieger's Acoustical Door and Window Wall Assembly can be manufactured for multiple performance requirements including bullet resistance, blast resistance, radio frequency shielding or any combination thereof.

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 of sidelight panels. The acoustical seal can also block in air and actually help regulate temperature and control smoke.
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 lighter weight, which makes installation faster and easier.
Eligible for LEED Credits
The Acoustical Door and Window Wall Assembly enables your project to earn LEED (Leadership in Energy and Environmental Design) credits for day light as well as acoustical standards that can help your project to become LEED certified.
