Insulation windows, also known as insulated or double-glazed windows, are designed to enhance energy efficiency and provide better thermal performance. These windows typically consist of two or more glass panes separated by a gap, which is filled with air or an inert gas like argon. The gap acts as an insulating barrier, reducing heat transfer between the inside and outside environments. This helps keep indoor spaces warmer in the winter and cooler in the summer, lowering energy consumption and heating or cooling costs.

Insulated windows also provide soundproofing, reducing external noise levels, and often come with coatings to block UV rays, protecting furniture and interiors from fading. Additionally, they reduce condensation and improve overall comfort in the home. Insulated windows are commonly used in residential and commercial properties to improve both comfort and energy efficiency
