For glass side- or frontwalls, chosen as design features for some court facilities, it is necessary to have a treatment applied to the glass such that players have an accurate view of the ball while spectators are able to enjoy watching play on the court. For this purpose McWIL-Hardmaas offers the ProView Club treatment, an open, or reversed, dot treatment that results in a relatively opaque playing surface and a relatively clear viewing opportunity at the same time. This treatment consists of one color ceramic screen-paint that is fused into the glass during the hardening process, creating a proper play wall with surface tension and a surface that cannot be degraded by racquets, sweat, glass cleaner, etc. This treatment is usually white, but other colors are available on request.

For three- or four-sided professional tournament glass courts, McWIL-Hardmaas offers ProView II, a special decal treatment incorporating a double-dot system (usually white over black) that provides optimal vision for players and spectators alike in an environment where there are no solid backgrounds to provide contrast. The ceramic decal dots are fused to the glass during the hardening process, similar to the screen-paint in ProView "Club". This process can be supplied in several colors to suit demand. The McWIL-Hardmaas portable tournament glass court is designed with the minimum number of unique glass panels; this allows cost-effective maintenance of spares, an important factor in a court that is to be erected and demounted regularly.
