The fire door upgrades represent a necessity for more and more people. If some home owners want to protect their families or goods, the business owners should be even more careful, especially when they are responsible for more lives. Such systems are even more indicated in the buildings or complexes with high fire risks. Besides, such problems may sometimes be caused by factors you do not really have control over, such as a defective fuse or a problematic plug. If you have no idea about these problems, the unpleasant situations will arise when least expected.
The upgrades can consist of three different doors:
Fire resistant doors
Smoke resistant doors
Fire and smoke resistant doors
Each of these doors is designed to prevent the spread of fire inside a particular area, room or office. They are used inside the buildings and only in fire rated walls. Their primary mission is to keep the flames in check, so the people trapped inside can exit or just wait for the firemen.
The legal requirements are set by specific associations and agencies, so most manufacturers have to adopt them.
The ratings are extremely important, since they can basically tell you how long the respective door will resist against the fire. For instance, a one hour rating is expected to resist the combustion for an hour. When picking a door, the walls are just as important. Typically, the door must have 75% of the wall ratings. For instance, if the wall has a three hour rating, the door must resist for about 135 minutes.
The rating is much diversified and may range between 20 minutes and four hours. It usually depends on how hard it is to access the respective area. When the firemen can barely reach to it, you obviously need a higher protection. However, the 20 minute fire doors are not that popular. Most of them are manufactured to block the smoke only.
In order to understand the ratings for a specific complex or building, you need to look after the building codes.
Absolutely all fire door upgrades will be equipped with some labels. The labels represent the proof that the respective doors have been actually tested and can meet the requirements. If you cannot find any labels, you are most likely looking at a useless door that cannot guarantee for your protection.
Reading the labels is not too complicated. You will find the manufacturing date, but also the rating and the duration. It is usually expressed in minutes. Other than that, the label is given by the testing agency that guarantees for the door. It is usually placed on the door edge. Sometimes it is mechanically fastened, only to stay in place. It will never be painted, regardless of the door colour, only for the customer to have access to such information.
If you experience any problems with the labels, seeking help from a local professional is a must. Aside from the actual explanations, you may also get some recommendations and advice.
