Abstract
A solar control film can include a multilayer stack including a transparent metal layer and a dark metal layer separated by an interference layer. The solar control film can have an improved solar control factor.
Claims20
A solar control film comprising:
- a substrate layer;
- a multilayer stack disposed between the substrate layer and the counter layer,
- wherein the solar control film has a visible light reflectance (VLR) of no greater than 12%, visible light transmittance (VLT) of no greater than 40%, and a solar control factor (SCF) of −0.38, and
- wherein the VLT and a solar heat gain coefficient (SHGC) of the solar control film satisfy the following formula:
- VLT-1.8(SHGC)≧SCF.
