Top 10 Questions We Get Asked About Window Film.

 

top-10

 

  1. Will window film make the glass crack? Only if the type of glass you have is incorrectly matched with the window film. There are different types of glass, toughened (heat treated), laminated & float are just a few. Matching the correct window film to the glass type is important. Bonwyke can help you carry this out.
  2. Why does the glass get hot now I have film applied? Because the film both absorbs heat and reflects it back through glass this has the effect of heating the glass up and is a sign that the film is working.
  3. Can I have a one way security film that will let me see out but nobody can see in? Yes, however there is a but. One way security film works on light differential. The light on one side of the film needs to be darker than the other. A person on the lighter side will see a mirror, the person on the darker side can see through. The difference needs to be greater than 20% for the one way effect to work.
  4. Do we sell an acoustic inhibiting window film? No, the films are not designed to reduce sound, so alternative glass would need to be fitted. 6.4 laminate, or triple glazed units give good insulation from sound.
  5. Can a film be added to the external face of shopfront glazing to reduce glare coming back off the glass, thus allowing better vision into the shop/office? No, any film added to the external face will only make the glass more reflective, and will not achieve the desired effect. The glass would need something to light going onto the glass, such as a canopy.
  6. Can glare be reduced in a car showroom, without the external vision into the showroom, being compromised? Yes, providing the glass is 2400 high or over, a lighter film can be fitted to the lower section (possibly internally) followed by an external dark sun strip running above 2000 FFL. The sun strip would then act as a low sun shield, without blocking vision into the show room.
  7. Can the same tools used for fitting vinyl and graphics be used for fitting window film? Some can, but really only the glass preparation tools. For the application of film to glass, there are specialist tools designed by window film applicators that allow more purchase when fitting the window film. The vinyl application pads and cards are not suitable for window film applications, as they are smaller, and do not allow enough pressure to be put onto the film.
  8. Can I have a light film to cut out the glare?  Like sunglasses the darker the film the better the glare reduction.
  9. What are the standards that Safety Film should conform to? All good quality Safety Film should conform to BS EN12600. There are a number of aspects to this standard depending on the film or glass type. Speak to us and our technical team if you would like to know more.
  10. How long does window film take to cure? Film can cure as quickly as 48 hours. However, complete curing will take up to 4 weeks if it’s a thicker film and in cool conditions.
