It doesn’t seem long ago since the typical conservatory was glazed with standard toughened double glazed sealed units in the frames and 16mm clear polycarbonate in the roof.
In fact for the conservatory roof, there were basically three polycarbonate options, clear, bronze or opal 16mm polycarbonate and for the frames there were two options, toughened glass or Low E toughened glass.
Since then, over the past few years, there have been some major changes to the glazing being specified in a conservatory which is particularly due to advancements in glazing technology.
For the conservatory frames, and in addition to the above two options, there is now more more to choose from including Pilkington energiKare (not suitable for south-facing conservatories) and Pilkington Activ self-cleaning glass.
When it comes to the roof, there is an even wider of options available including 25mm, 32mm and 35mm polycarbonate thicknesses for improved thermal efficiency. There are also more colours to choose from including blue, solar ice, grey heatguard and silver heatguard.
Solar control foil inserts can also be fitted inside the polycarbonate, achieving a solar reflection performance of around 80%. These inserts are available in green, blue, gold and silver.
Perhaps the biggest change in conservatory roof glazing is the popularity of a glass roof. Normally 24mm thick double glazed units are available in a variety of options including standard toughened units, self cleaning and solar control options such as Pilkington Activ Blue and Aqua Green which are both self cleaning and solar control, making the conservatory more comfortable all year round.
