Insulated Glass (IG), also known as Insulating Glass Units (IGUs), or sometimes double-pane or triple-pane glass, is a type of window or glass unit made of two or more panes of glass separated by a space. This space is filled with either dry air or a gas like argon or krypton, designed to reduce heat loss and gain.

1. What is Insulated Glass (IG) and how does it work?
Insulated Glass, also known as Insulating Glass Units (IGUs), consists of two or more panes of glass separated by a space filled with dry air or a gas like argon or krypton. This design creates an insulating barrier that significantly reduces heat transfer, helping to maintain indoor temperatures and improve energy efficiency.
