Spacers

A. A spacer bar and U-value are closely linked because the spacer material impacts heat loss at the window edge. An aluminium spacer increases U-values due to heat conduction, while a warm edge spacer lowers U-values by providing better insulation.

A. A steel spacer bar is used in fire rated glazing because it provides better heat resistance than aluminium or warm edge spacers. The steel spacer bar helps maintain the stability of the sealed unit in high temperatures, ensuring it meets fire safety regulations.

A. A double glazing spacer bar holds the desiccant inside the sealed unit, allowing it to absorb moisture through small holes in the spacer. This helps prevent condensation from forming between the glass panes.

A. A warm edge spacer bar vs aluminium offers significant energy efficiency benefits. While aluminium is strong and cost effective, it conducts heat, reducing insulation. In contrast, a warm edge spacer bar vs aluminium provides superior thermal performance by slowing heat transfer.

A. An aluminium spacer bar has been widely used in double glazing because it is lightweight, strong, and cost effective. However, an aluminium spacer bar is highly conductive, meaning it transfers heat out of the home, reducing thermal efficiency.

A. A warm edge spacer bar is designed to reduce heat loss around the edge of a sealed unit, improving energy efficiency. Acting as a thermal break, a warm edge spacer bar slows down heat transfer, lowering the U-value of the window.

A. 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.
