STC Ratings for More Kolbe Products

At Kolbe, we understand the growing importance of blocking undesirable noise. That's why we have invested resources into acoustic testing of more and more of our products. In fact, we have more than doubled the number of products tested for Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) ratings.

Not only have we had products with standard glass tested, but with various glass and other options, including the addition of combination storm/screen units on double hungs. This provides valuable information when determining which products, glass, and other options will help to fulfill a project's specific needs.

We have acoustic values for products within the VistaLuxe® Collection, Ultra Series, Heritage Series, Classic Series, Latitude® Series, and Windquest® Series. Review the data on our Acoustic Data page to see the wide array of Kolbe products tested for sound transmission.
