Abstract

A light diffusing solar control film includes a multilayer film that transmits visible light and reflects infrared light, and a light diffusing layer or surface adjacent to the multilayer film forming a light diffusing solar control film. The light diffusing solar control film has a haze value of 10% or greater.

Description

technical field [0001] The present invention relates generally to light-diffusing solar control films, and more particularly to light-diffusing solar control laminates and light-diffusing solar control glazing units. Background technique [0002] There is a known need for energy efficient windows and glazing systems. Selection of a specific type of window depends on a variety of factors including UV, visible and optical performance, aesthetics and climatic conditions. Glazing units with low solar heat gain and low thermal insulation may be sufficient in cold predominantly climates, while moderate solar heat gain with high thermal insulation is required in hot predominantly climates. [0003] Low emissivity (Low-e) coatings reflect mid to far infrared energy and are used in insulating glazing units. Low-E windows are especially useful in climates where heat prevails. There are two types of low-E coatings. A pyrolytic low-E coating, often referred to as a "hard coat", is a...
