Silence is Golden Series

Sound reducing window technology

Sleep like a baby

The Silence is Golden series was developed by Lang Exterior to bring added peace and quiet to your home - the kind of peace and quiet to let you "sleep like a baby."

The noise problem

Today, it's often difficult to keep outside noise from creeping into the household. Trains, planes, barking dogs, noisy motorcycles, kids playing with basketballs and of course auto traffic are just a few of the things that can disturb the tranquility of the home.

How does Silence is Golden help?

Silence is Golden was designed to significantly reduce noise right at the glass. Through an innovative set of modifications to the insulated glass unit, Silence is Golden can cut noise dramatically.

How much noise reduction should I see?

When exterior noise levels are 70dBA, Silence is Golden can provide sound attenuation for interior sound levels that do not exceed 45dBA (see dBA chart to the left).

The listing below shows STC and OITC noise ratings for a variety of Lang windows and patio doors. STC is sound traveling from room to room, while OITC is sound traveling from outdoors to inside. In both cases, higher numbers mean more noise insulation. These ratings come from an independent, accredited lab.

  • Platinum 2400 Series Double Hung windows with SIG:
