Retrofitting a window will involve replacing just the glass. The existing window frame stays then a new glass and energy-efficient window is installed. This makes the job less complicated and a lot more affordable, rather than removing the exterior materials of the home in order to install the window.
Why get retrofit double glazing?
Windows can have a drastic effect on the thermal performance of a building.
Up to 40% of a home’s heat can be lost through conduction or radiation at the window, and up to 87% of its heat can enter through solar gain. This unwanted heat flow can be devastating for the energy efficiency of any project.
Retrofitted double glazing is the best way to improve the insulating properties of the glazing itself. This type of window combines two panes of glass with a metal or polymer spacer between them.
It’s the space between the glass that provides the benefits of this glazing system - the pocket of air (Argon, which has low conductivity) acts as a buffer and resists heat flows. The Low-E glass layers can reduce solar heat gain in summer and decrease heat lost in winter.
Last but not least double glazing adds an extra layer of security as the two panes are more difficult to break than one.
