Single glazing
A single pane of glass offers minimal insulation because glass is a good conductor of heat. As a result, much of the warmth in your room literally goes out the window.
Double glazing
Double glazing traps a layer of air between two panes of glass, substantially reducing heat lose through the window because air is a poor conductor of heat. Adding a Low E coating to the inside of one of the panes of glass can further improve insulation because the coating reflects heat back into the room.
Triple glazing
Triple glazing provides two insulating layers of air between three panes of glass, reducing heat loss even further as air is a poor conductor. This delivers enhanced thermal efficiency compared to single or double glazing.
Selecting the right glass for your home.
Glass plays a critical role in your home's appearance, comfort, and energy efficiency. The right glazing can help reduce heat loss, minimize noise, block UV rays, and improve year-round comfort. With single, double, and triple glazing options, along with coatings and insulating technologies, choosing the right glass can significantly impact your home's thermal performance and security, as multi-pane glass is far more resistant to breakage than a single pane.
Understanding glazing options
Single glazing: A single pane of glass provides minimal insulation, allowing significant heat loss in winter and heat gain in summer. It is rarely used in modern homes due to its poor energy efficiency.
Double Glazing: Consists of two panes of glass with an air or gas-filled gap in between, acting as an insulating barrier. This reduces heat transfer, helping keep homes warmer in winter and cooler in summer. Adding a Low-E coating, which is highly recommended, reflects heat back inside, further improving thermal performance. Please see below for why we recommend it.
Triple Glazing: Features three panes of glass with two insulating air or gas-filled gaps for even greater insulation. Ideal for colder climates or high-noise areas, triple glazing provides maximum energy efficiency, noise reduction, and condensation control.
