What is a spacer bar, and why is it important in double glazing?

A spacer bar for double glazing separates the glass panes in a sealed unit, creating an insulated cavity that improves thermal performance. It also holds the desiccant, which absorbs moisture to prevent condensation. Choosing a high quality spacer bar for double glazing ensures better insulation, energy efficiency, and a longer lasting window. At Glasscraft, we provide durable spacer bars for double glazing to optimise performance and longevity.
