Building Regulations surrounding the energy efficiency of windows have seen changes in recent years that have strongly affected the windows those self-building, extending and even renovating can choose in order to comply. “The energy efficiency of most types of windows has improved significantly over the past 20 years, driven by both the development in technology of the frames and glass and by the demands of Building Regulations for greater thermal efficiency,” explains Edward Stobart, sales manager at IDSystems.

Several elements contribute towards making a window energy efficient —and the level of energy efficiency required will vary depending on the type of house you are building or living in.

“What makes a window energy efficient is its ability to prevent heat transfer so that interior temperatures remain comfortable all year round, whatever the weather outside,” explains Victoria Brocklesby, chief operating officer at Origin. The two main elements to consider when choosing energy-efficient windows are the glazing and the frame material. Also, the quality of the windows, how they are installed and even how they are positioned can all effect their energy-efficient credentials, too.
