What VLT Means on a Window Film Spec Sheet
VLT, or visible light transmission, tells you how much visible light passes through window film. Learn how VLT affects appearance, glare, privacy, heat expectations, and flat glass film conversations.
Read articleWhat TSER Means and Why It Is Not the Whole Story
TSER, or total solar energy rejected, is a common window film performance number. Learn what TSER includes, how UV, visible light, and infrared contribute to it, and why TSER should not be sold as simple heat rejection.
Read articleSHGC Explained for Window Film Conversations
SHGC describes how much solar heat gets through a glass and film system. Learn how to explain it without treating one spec number as the whole recommendation.
Read articleTotal Solar Absorbance, Reflectance, and Transmittance on Film Specs
Total solar absorbance, reflectance, and transmittance describe where solar energy goes at the glass and film system. Learn how these window film specs affect performance, appearance, and compatibility conversations.
Read articleVisible Reflectance, Interior Reflectance, and Exterior Reflectance
Visible reflectance, interior reflectance, and exterior reflectance affect how window film looks from each side of the glass. Learn how these specs affect appearance, glare, privacy, and customer expectations.
Read articleEmissivity and Low-E: Plain-English Definitions
Plain-English definitions of emissivity and Low-E glass for flat glass window film conversations, including why Low-E coatings affect compatibility checks.
Read articleU-Factor and Window Film
U-Factor describes non-solar heat transfer through a window system. Learn how it differs from SHGC, TSER, and direct sun heat in window film conversations.
Read articleIR Rejection vs Heat Rejection: Plain-English Difference
IR rejection and heat rejection are often treated as the same thing, but they are not. Learn what IR rejection means on a window film spec sheet and how it fits into flat glass film recommendations.
Read articleGlare Reduction: How to Explain It Without Overpromising
Glare reduction is a common window film spec, but it depends on visible light, window direction, room layout, and customer expectations. Learn how to explain glare reduction on flat glass jobs.
Read articleUV Rejection: What It Does and Does Not Tell You
UV rejection is a common window film spec, but it does not explain total heat rejection or complete fade prevention. Learn what UV rejection means for flat glass film jobs.
