Did you know?

Did you know that Lang Exterior makes a glass option that can significantly reduce the amount of noise that comes into your house? Well it’s true they do!

Inroducing: Silence is Golden

Silence is Golden was developed by Lang Exterior to bring a peaceful atmosphere that could enable even the most sensitive sleeper to be at peace. With this upgrade (available on most Lang vinyl windows) you will find that even the most annoying exterior noises will be significantly reduced. With these new glass innovations from Lang Exterior now you can sleep like a baby with your new vinyl windows.

But how does it work?

When exterior noise levels are 70dBA or less, these replacement windows and patio doors would provide adequate sound attenuation so that the interior sound levels do not excede 45dBA. You will begin to hear less and less of the common and irratating noises such as:

  • Barking Dogs
  • Bouncing Basketballs
  • Trains at 200 Feet
  • Motorcycles
  • Noisy Neighbors
  • Large Trucks

How to Read the Technical Ratings:

STC & OITC are rating systems used to measure sound reduction. STC is used to rate sound traveling through an interior wall (for instance from the living room to the kitchen) and OITC is used to rate a sound traveling through an exterior wall. Higher STC/OITC ratings represent more efficient sound reduction through a surface. The STC rating of a typical wall without windows is 36. Langs vinyl windows have produced the following results when tested for STC and OITC:

Technical Ratings:

Platinum windows: STC 34/OITC 28

Renaissance: STC 34/OITC 27

Glide: STC 31/OITC 26

Decorative Dimensions: STC 34/OITC 27

PowerWeld Slider Series: STC 33/OITC 28
