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.
