Protective Dial Covers

 

We offer a range of impact resistant covers to go over our dials and hands to help protect against vandalism.

 

Protective covers can often detract from the look of the clock so we would always suggest what we feel the most suitable style is for the chosen clock design.

 

It's important to note that condensation and fogging may occur, but most installations may never experience these issues. However, if needed, ventilation holes can be drilled in the acrylic cover to help regulate air temperature. Using an old drill bit, it's ideal to create three holes with a diameter of 4 or 5mm in the return edge, preferably around the bottom.

Glass and acrylic fogs up when there's a significant difference in temperature and humidity on either side of the surface. This phenomenon occurs due to condensation. When warm, moist air comes into contact with a cooler surface, such as glass, the air cools down rapidly. As it cools, it loses its ability to hold moisture, causing the water vapor to condense into tiny droplets on the surface, creating fog or mist.

Condensation typically happens when the temperature of the glass or acrylic is below the dew point of the surrounding air. The dew point is the temperature at which the air becomes saturated with moisture and can no longer hold it in vapor form. When the warm, moisture-laden air encounters a surface below this temperature, such as a cold window, clock cover or mirror, condensation occurs.
