As with all products from Neuffer, round windows come with quality glass that helps to prevent energy loss. Depending on the material and opening chosen, double or triple glazing will be available. Featuring two or three panes, these glazings are thicker than single pane glass and have spaces filled with inert, sealed argon gas. Denser than air, the gas helps to slow the transfer of heat, keeping interiors cool during hotter periods and warmer when it’s cold out. The surface of the glazing then also features a low-e coating to reflect solar radiation.
Although round windows feature our purpose-designed glazing, certain energy-saving profiles are not available with the shape. To compensate for this and improve thermal insulation, a warm edge spacer can be selected. This is extra insulation that is added to the profile during manufacturing and acts as a thermal break, helping to prevent energy loss via conduction.
