Glass fiber, or fiberglass, is made up of tiny glass rods less than 1/20 the diameter of a human hair. These rods are pressed together, creating tiny voids between the fibers. These voids absorb the sound. Glass fiber tends to fall into a high NRC range, but it has a low STC. Abacking such as foil can be used to improve the STC. ...

frames are relatively new. They are light, durable and strong, even in narrow sizes, they have excellent insulating qualities, and they do not expand and contract with heat and cold as much as other frames. They are also more expensive than other types of windows.

fiber optics

A strand of glass thinner than a human hair that is capable of carrying a light signal close to 70 miles without amplification. The light can be pulsed in a single wavelength to represent 45 Gigabits of information. Adding a wavelength doubles that capacity. In the year 2000, the wavelength technology is at 16 and growing.
