Wooden fire doors have a special design, the structure of which prevents the spread of flame in the event of fires and fires. However, doors with fire protection can also be made from other common materials that can delay the fire in case of danger of its penetration into neighboring rooms. So, fire - prevention wooden doors are most often installed to protect housing. And metal structures can be seen in offices and industrial enterprises.
Why should fire doors be preferred?
By installing wooden fire doors from the manufacturer, the consumer receives a thoughtful design made of materials that can withstand the highest temperatures when the surrounding surfaces ignite without deformation, loss of shape and quality. Often, along with wood, the most refractory materials, such as steel or aluminum, are used here. Such bases are not susceptible to corrosion, mechanical damage and have a long service life.
If we talk about the most innovative developments in the field of manufacturing doors with fireproof properties, then recently ceramic designs have proven themselves excellently. This type of fire door contains a protective coating in the form of a special solution of ceramic mass, the surface of which becomes even harder with increasing temperature. However, this option has not yet managed to become widespread.
What should I look for when choosing wooden fire doors? Opinions of experts
The main quality that experts pay attention to when choosing doors with fireproof properties is the maximum limit of their fire resistance. This indicator is calculated in minutes and shows how long the door can withstand an open flame, providing protective functions.
According to experts, the simplest, budget wooden fire doors are able to withstand fire for at least 15 minutes from the moment of fire. The highest rate recorded during testing of such products, to date, remains fire protection for 120 minutes.
Truly reliable, high-quality fire doors must be certified according to the results of special tests, as evidenced by the presence of appropriate markings with the following data:
- information about the manufacturer and the name of the product;
- indicator of refractory protection;
- batch number;
- a brief description of the features of the technology of the production process;
If the wooden fire doors or the metal structure have glass, then a certificate with the above information must also be attached to it.
How and where should fire doors be installed?
Experts believe that, first of all, fire-prevention wooden doors EI 60 and other popular models should be installed in public premises, the operation of which occurs when there are substances and equipment that conceal the potential danger of fire.
Door structures with fire-fighting properties should also be installed, separating residential premises from office premises, if any, are located on the same floor. At the same time, it is necessary to ensure that their canvas opens up towards the exit, which is very important when evacuating people.
According to the generally established safety requirements, wooden fire doors must be at least 2 meters in height. At the same time, the choice of width depends on the conditions of a particular room, in particular on the estimated flow of people who will be massively evacuated through an existing opening.
Properties of fire doors made of wood
Despite the ability of the tree to burn and maintain the spread of flame, most experts advise protecting the housing with just such structures, because only they have an obvious aesthetic appeal. However, the door fire-resistant wooden EI 30 and other similar structures can only relatively block the path of the flame, according to expert reviews. Therefore, it is natural that when a fire occurs, such a structure will partially or completely collapse, which will require its dismantling and replacement.
Externally, fire-resistant wooden doors can hardly be distinguished from conventional wooden structures. Therefore, they fit perfectly into any interiors and can be used as not only input, but also interior.
Steel Fire Doors
According to expert reviews, structures made of steel have excellent properties in terms of strength, reliability and durability. They can differ in a wide variety of systems. So, one of the most common options is the use of steel box cloths with a lining in the form of metal sheets with a wide or narrow fold on both sides. However, depending on the available capabilities, requirements and conditions, you can give preference to any other designs.
Fire doors based on aluminum profiles
Despite the flexibility of a material such as aluminum, fire experts design this material as metal. The aluminum door system is based on the use of solid panels in the absence of visible joints. Separate profiles are fastened here with special clips. External cladding of aluminum doors is represented by silicate refractory strips.
Combined Models
In combined fire products, steel and wood elements are used along with an aluminum shell. Such structures usually contain wood protected on all sides, richly impregnated with refractory substances. Due to the possibility of combining a number of individual materials in one product, combined models are characterized by a wide variety of textures, shapes and surfaces.
