What Is a Sealed Glass Unit?
A sealed glass unit (SGU), commonly referred to as an insulated glass unit (IGU), consists of two or more panes of glass separated by a spacer and sealed together to create an airtight space. This design helps reduce heat transfer, minimize energy loss, and enhance indoor comfort. The space between the glass panes is often filled with an inert gas, such as argon, to improve insulation.
Why Choose Sealed Glass Units for Your Construction Project?
Here are some of the benefits of sealed glass units:
Energy efficiency: Sealed glass units reduce heat loss in winter and limit heat gain in summer, helping to maintain a stable indoor temperature. This results in lower energy consumption for heating and cooling systems.
Condensation reduction: Sealed glass units help reduce condensation by preventing moisture buildup between panes, which can lead to mould growth and damage to window frames.
Noise reduction: Double- and triple-pane sealed units provide better sound insulation, reducing external noise levels and enhancing indoor comfort.
Increased security: Sealed glass units offer improved durability and strength compared to single-pane glass, providing an added layer of security for homes and businesses.

When to Replace Sealed Glass Units?
Sealed glass units should be replaced when signs of failure appear, such as condensation between panes, fogging, or reduced insulation performance. A broken or damaged seal allows moisture to enter, affecting visibility and energy efficiency. Increased energy bills or drafts near windows may also indicate a decline in performance. If the glass appears cracked or the frame is deteriorating, replacement is necessary to maintain structural integrity and indoor comfort. Bethel Windows & Doors provides high-quality sealed glass units to restore efficiency and clarity while preventing further damage to your windows.
