What are spacer bars?
The spacer bar is a sealing of the edge used in the glazing unit windows and doors. It is used in both single-chamber and double-chamber panes. Depending on what material it is made of, it can have a very beneficial effect on the overall heat transfer coefficient of the entire window and, consequently, on energy savings.
The warmest spacer bars used by us – from the Swiss brand Swisspacer – are made of plastic and filled with a hygroscopic agent in the form of granules. They are distinguished by excellent aesthetics and availability in many colors.In our offer you will also find Chromatech Ultra warm bars with a hybrid design made of stainless steel and PVC.
Why do we need spacer bars?
They enable a significant reduction in the phenomenon of water vapor condensation at the junction of the bar and the glazing unit. A higher temperature at the edge of the inner glass in the glazing unit allows for an increase in the relative humidity of the room by several percent. If traditional aluminum spacer bars were used, this increased humidity, under certain conditions, would cause water to condense on the surface of the glass. Interestingly, single-chamber glazing units with a warm edge spacer bar performs better in this respect than a two-chamber glazing unit with an aluminum spacer bar.
