Why is my conservatory hot in the summer and cold in the winter?

To enjoy your conservatory all year round we would recommend choosing an Insulating Glass Unit that combines a self-cleaning glass from the Pilkington Activ™ Range as the outer pane (especially for those harder to reach areas such as roofs), combined with a high performance low-e inner pane such as Pilkington Optitherm™ S1 Plus. This way, the combined properties of both solar control and thermal insulation can help maintain a comfortable temperature throughout the year.

Pilkington Optitherm™ S1 Plus, which usually forms the inner pane of a double-glazing unit, has a special low-e coating to help reduce the amount of heat that escapes through your windows. This is particularly important for conservatories in winter, when it can be difficult to maintain a comfortable temperature. The special energy-saving coating on Pilkington Optitherm™ S1 Plus allows the sun’s rays through, but reflects heat from radiators and fires back into your home, saving energy and reducing your heating bills.

For glazing that is South or West facing (these receive the most solar heat) we would recommend Pilkington Suncool™ One 60/40 to provide year-round comfort especially in large areas of glazing such as bi-fold doors or orangeries. 

How it works 

In the warmer months, the coating reflects the sun’s heat, helping to maintain a cooler temperature. When winter arrives, the high-performance thermal insulation coating helps to keep rooms warmer. As well as excellent solar control Pilkington Suncool™ One 60/40 offers a low internal reflection, reduced glare, and can help protect furnishings from harmful UV.
