Wooden fire doors have a special design, the structure of which prevents the spread of flame in the event of fires and outbreaks. However, doors with fire protection can also be made from other common materials that can hold fire if there is a danger of its penetration into neighboring rooms. So, wooden fire doors are most often installed to protect housing. And metal structures can be seen in offices and industrial enterprises.
Why choose fire doors?
By installing wooden fire doors from the manufacturer, the consumer receives a well-thought-out design made of materials that can withstand the highest temperature 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 resistant to corrosion, mechanical damage and have a long service life.
If we talk about the most innovative developments in the production of doors with fire properties, then recently ceramic structures have proven themselves to be excellent. This type of fire door contains a protective coating in the form of a special solution of ceramic mass, the surface of which only becomes harder with increasing temperature. However, this option has not yet become widespread.
What should I pay attention to when choosing wooden fire doors? Expert opinions
The main quality that experts pay attention to when choosing doors with fire 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, budgetary wooden fire doors are able to withstand fire for at least 15 minutes from the moment of ignition. The highest performance 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 product name;
- indicator of fireproof protection;
- batch number;
- a brief description of the technology features of the production process;
If wooden fire doors or metal construction have glass, then it must also be accompanied by a certificate with the above information.
How and where should fire doors be installed?
Experts believe that, first of all, wooden fire doors EI 60 and other popular models should be installed in public premises, the operation of which occurs in the presence of substances and equipment that hide a potential fire hazard.
Door structures with fire properties should also be installed, separating residential premises from office premises, if they are located on the same floor. At the same time, you need to make sure that their canvas swings open towards the exit, which is very important when evacuating people.
According to 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 expected flow of people who will massively evacuate through the existing opening.
Properties of wood fire doors
Despite the ability of a tree to burn and maintain the spread of flame, most experts advise protecting housing with just such structures, because only theyhave obvious aesthetic appeal. At the same time, wooden fire doors EI 30 and other similar structures are only able to relatively block the path of the flame, according to expert reviews. Therefore, it is quite natural that in the event of a fire, such a structure will partially or completely collapse, which will require its dismantling and replacement.
Externally, wooden fire doors are practically indistinguishable from ordinary wooden structures. Therefore, they fit perfectly into any interiors and can be used not only as entrances, but also as interiors.
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-shaped canvases with sheathing 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 malleability of a material such as aluminum, fire protection structures made of this material are referred to by experts as metal. The aluminum door system is based on the use of solid panels with no visible joints. Individual profiles are fastened herespecial clips. The outer skin of aluminum doors is represented by silicate refractory strips.
Combination models
In combined fire protection products, steel and wood elements are used along with an aluminum sheath. Such structures usually contain wood protected on all sides, abundantly impregnated with refractory substances. Thanks to the ability to combine a range of individual materials in one product, the combined models feature the widest variety of textures, shapes and surfaces.
