Double glazing is a type of window that consists of two panes of glass with a small gap between them. The two panes of glass act as a barrier to reduce the amount of heat that is transferred through the window. This provides increased insulation, which can help to reduce heat loss from your home and improve energy efficiency. We source the best components and pay attention to the details that make the difference.

Unlike double glazing, where two panes are built into a single unit, secondary glazing involves a separate pane that can be removed, creating a flexible and effective solution for enhancing window performance. This is especially beneficial in period properties where retaining the original window structure is preferred. Secondary glazing offers key features like energy efficiency and noise reduction, providing a cost-effective upgrade to traditional single glazing.

The difference between A and A+ rated windows are that an A-rated window will only release as much heat as they let in from outside. An A+ rated window will let in more heat from the outside than it releases from the outside. So A+ rated windows will increase the ability to gain heat from the outside. The strategic placement of glazing allows abundant natural light to fill the space, creating a warm and inviting atmosphere.
