What can be laminated between layers of glass to reduce unwanted heating of the building interior?

Laminating reflective film between layers of glass can significantly reduce unwanted heating of a building’s interior. Reflective films are designed to reflect solar radiation, thereby minimizing the amount of heat transmitted through the glass. This ability to reflect sunlight helps in maintaining a comfortable indoor temperature, reduces the reliance on air conditioning, and increases energy efficiency.

While thin metal sheets may offer some reflective qualities, they do not provide the same level of effectiveness as purpose-designed reflective films. Insulating foam is typically used for thermal insulation but is not practical for lamination between glass layers in the way reflective films are. Specialized coatings can also aid in reducing heat gain, but reflective films specifically target solar radiation effectively, making them an optimal choice for this purpose. Thus, using laminated reflective film aligns directly with the goal of reducing unwanted heating in buildings.
