Fire doors are built to withstand the effects of lire for periods of half, one or two hours depending on where the door is to be used. You may have to fit one to comply with the Building Regulations for example, if you build a garage on to your house, any door connecting the house to the garage must have at least half an hour's fire resistance. A fire-resisting door should protect against smoke as well as checking the movement of the fire. The doors are commonly referred to by their fire performance - a 30/30 door or a 30/20 door, for instance. Fire-resisting doors are usually flush doors formerly with plasterboard or asbestos cores but nowadays increasingly with flaxboard or chipboard cores. They should be fitted in fire-resisting frames and usually need to be self-closing.
There are various online sites from where you can buy the best steel security doors, but before buying any security door you must be aware of its warranty, reliability, endurance, security and maintenance. Also check whether the security door is properly tested and is meeting secure by design standards (PAS23 and PAS24).
4. The door gets stuck - there is either an obstruction or there's a major issue with the remote itself. Check and remove any foreign objects.
