The Cover Glass USA system consists of specially designed glass panels between proper upper and lower steering panels. Each individual glass panel can slide freely to the left or to the right. The glass panels can easily slide of corners no matter what the angle is.

Cover Glass USA profiles consist of specially designed AL profiles made in compliance with DIN1748. Profiles are powered coated or anodized, enduring environmental influences. All metal parts are non-corroding.

Using regulation profiles allows for easy installation and adjustment of height. The upper and lower steering profiles are installed on the building using approved anchors and high grade screws.

Glass panels consist of tempered glass with polished edges. Glass can be 3/8 or 1/2 inch or according to project needs. The upper and lower part of each piece of glass is fixed into the glazing profiles, allowing them to glide effortlessly.

Number and measurement of the glass panels are chosen in relation to the system length. Glass panels are normally 26 to 32 inches in width and 80 to 108 inches in height. Other sizes are available. Glass panels when opened, fold neatly back and into the corner allowing for totally unobstructed views. The system is locked from the inside.
