In the same way that the insulating layer of double glazing helps keep the cold temperatures out, it reduces the impact of hot temperatures. Thus, the benefit for you is that your home will be noticeably cooler in summer.

The shift from single glazing to standard double glazing will reduce the solar heat gain through your windows by around 13%.

By using glass with improved thermal properties (such as Low-E glass) and tinting, the reduction in solar heat gain through your windows can be greater than 50%.
