Roller shutter doors are usually used on the garage if you are going to use them in a domestic setting. They can also be used in business, in areas like warehousing or workshops, opening up to allow access to foot traffic and palette trucks. They are quick and easy to open, and one of the other important benefits is that they are very well insulated, offering you the opportunity to keep your home or business at a more stable temperature and saving you money.
You do need to choose the correct type of roller door if you want it to be a thermally efficient as possible. You should choose at least a double skin, possibly tripe, if this is the main benefit that you want to feel from your roller shutter door. You should also choose a well insulated material, like steel or aluminium, that is going to keep the heat in.
