You can use your conservatory throughout the year however some people find them too cold to sit in when its winter. Here are a few tips to help keep your conservatory nice and toasty warm through the cold weather.
Insulation is a huge factor! Glass is not as good as a brick wall so therefore youre best of going for a more modern design that has thick double glazing.
Ensure the doors are fully draught proof and any other possible sources. To add warmth you can always have blinds or drapes installed to trap in some of the heat.
Heat can also be lost through the floor, as you walk on the floor if it feels cold it will make the room feel even colder. It is best you add a thick carpet with a good quality underlay for added warmth.
