Charcoal Charcoal 20 window film is a hybrid film. It’s construction utilises a non reflective film laminated to a reflective film. This film is ideal for commercial and residential applications as it has a high glare rejection of 80% as well as an excellent heat rejection.

From the outside it has a semi-reflective charcoal look, yet from the inside during the day it has a tinted charcoal look, making it see-through. Commercial applications include computer rooms as well as open plan offices. Over the years this product has been very popular due to its performance.

Obviously the cost is higher than a normal tinted dyed film as it is two films laminated together. This film has a scratch resistant coating which aids installation and maintenance and increases the life of the film.
