A window with a low U-factor will keep the heat out in the summer, but it may not be appropriate for areas that are subject to high rain and wind. One of the biggest factors that affects the performance of a window is the quality of the materials used to make it. This includes the type of glass and sealant used to create the window.

As time passes the sealant may become loose or break down and allow air and moisture to enter. This can lead to the formation of condensation inside the double glazing unit. This is usually an indication that the sealant is damaged and needs to be replaced. Condensation is most common in windows with multiple panes and is usually noticed as a fogging effect between the glass. This is due to the fact that the inner panes of a multi-pane window have a spacer bar which is filled with desiccant, a chemical that sucks up any moisture that gets trapped between the glass. If the seal is damaged by even the smallest chip or crack, the insulating properties of a multi-paned window will be diminished and you'll notice that windows appear cloudy on the sunny days. This problem is less likely with newer replacement windows because they are made using Warm Edge technology. This helps reduce thermal transfer along the glass edges.

The units are advertised as having a viewline between 8 and 10 millimeters. However, they use a "warm edge" spacer bar that reduces visibility. This means that the sealant at the back of the unit needs to be reduced in thickness to get this sightline. This could have a significant impact on the IGU's capacity to resist moisture and gas loss, which can lead to premature IGU failure. The main problem with these units is that they do not meet the thermal performance criteria of Part 2 and 3 of EN 1279 which requires a minimum sealant thickness over the spacer bar of 8mm. This can result in reducing the efficiency of the unit by about 10 percent. These units are then guaranteed by the manufacturer to meet this standard.
