Cold Weather Ahead!

Tips for a successful Installation…

All self-adhesive vinyl including perforated window films have a minimum application temperature and low temperatures can make installation difficult, if not impossible. If temperatures are below the minimum application temperature the adhesive can become hard, resulting in the material failing to bond effectively to the glass.

Extensive testing has shown that Contra Vision® perforated window films can be applied reliably at 5°C/41°F.

This is considerably lower than most other perforated window films, which typically have minimum application temperatures of 10°C/50°F.

In extreme climates, temperatures may never reach our minimum application of 5°C/41°F. Graphics applied to the inside of a window have many advantages including allowing for colder weather applications. For Applied Inside one-way vision graphics we have Performance Clear for long-term applications or Campaign Clear  for short-term applications.

The minimum application temperature of 5°C/41°F refers to the temperature of the glass, not the air temperature, as the temperature of the glass can remain lower than the surrounding air. We recommend that in cold weather Contra Vision® perforated windows films are applied in the afternoon, preferably after the windows have been warmed by the sun. Temperature should not drop below 0°C/32°F within 2 hours of application and not drop below -5°C/23°F within 24 hours of application. The use of a heat gun to warm the surface of a window is not recommended as this may cause the glass to crack.

In the winter months storage temperatures can significantly drop and we recommend that the material is warmed to room temperature well before application. The same applies when transporting graphics, the material being allowed to reach room temperature before application, particularly if left in a cold vehicle overnight.

During application, ensure that the surface is dry and free from any condensation. Thoroughly clean the surface from dust, grease or any contamination that could affect the adhesion of the material. Do not use a chemical adhesion promoter. Application must be dry, ensuring that the graphics are cut back from the edge of the window by 1-3mm (3/16”-1/8”) and that all joins are butt joins. Do not overlap. We recommend that the graphics are not cleaned for a minimum of 24 hours after installation.
