INTERIORS WINDOW FILM 101 Darrell Smith, executive director of the International Window Film Association, speaks with College Planning & Management concerning the uses and benefits of window film for new and existing campus facilities. C P&M;: WHAT IS WINDOW FILM? IS THERE MORE THAN ONE TYPE? If so, what would be the best choices for educational interiors? SMITH: Window fi lm is a flexible product composed of one or more layers of coated or chemically treated polyester that can be installed on glass. It is primarily used for retrofit applications to existing windows. There are several types of window fi lm products, with each type specifically designed for a particular end use. These include solar-control fi lms, insulating fi lms, ultraviolet (UV)blocking fi lms, safety/security fi lms, 78 glare control/privacy fi lms, decorative fi lms, and automotive fi lms. Since all quality window fi lms offer up to 99 percent UV-protection, and solarcontrol fi lms can be had with different levels of insulation improvement, then for exterior windows solar-control and safety/security fi lms (or products which offer both properties in a single product) would likely be the most beneficial. For interior windows used on doors or glass partitions, decorative products or safety and security products would be used. CP&M;: What are the benefits of window fi lm? SMITH: Solar-control films can block as much as 80 percent of the solar heat coming through glass into a building, thus decreasing the heat load on the air conditioning system and creating reduced energy costs. Professionally installed window film can reduce cooling costs by up to 30 percent. Films can be darker for glare control or privacy purposes or else appear almost totally clear, depending on the required building and customer needs.
