Red Seal Glazier Practice Exam

The installation of window films significantly enhances glazing performance primarily by providing added UV protection and improving energy efficiency. Window films can block a substantial amount of ultraviolet (UV) rays from the sun, which helps in preventing skin damage and fading of interior furnishings. This protective feature is essential for maintaining the longevity of flooring, upholstery, and artwork.

In addition to UV protection, window films can improve energy efficiency by minimizing heat gain during the summer and retaining heat during the winter. This can lead to lower energy costs, as less energy is required for heating and cooling. By reflecting solar energy away from the building, window films contribute to a more comfortable indoor environment and reduce reliance on HVAC systems.

While other options might mention important features like sound insulation or aesthetic changes, the most critical benefits in terms of glazing performance involve UV protection and energy efficiency, making the second choice the correct one.
