External doors are a showcase of the house, so they should not only be aesthetically blended in with the façade of the building, but also suppress noise from the outside and provide adequate thermal insulation. Exterior doors should also be solidly made, protecting against burglary. What door building standards should we take into account when choosing the perfect exterior door?
Construction standards windows and doors
Window and door joinery should meet certain building standards, which are specified by the relevant regulations. These standards specify the types of doors and the dimensions they must have in order to be approved for use. The current building standards for doors say that external doors should be at least 90 cm wide and 200 cm high in the light of the frame, and the height of the threshold should not exceed 2 cm. These are the minimum dimensions that allow the use of doors by people with disabilities and allow a pram to pass through them. Of course, the dimensions of the door can be larger than those indicated above, the standard height of the door in developer apartments is on average 210 cm. It is worth paying attention to this at the design stage of the house, because it is then necessary to make a larger door opening at the stage of early construction work. However, the building standards of the door do not specify the position of the handle in the external door, so the height of the door handle depends on your preferences. The standard distance of the handle from the floor is 1m, but if children or tall people live in the house, you can manipulate the height of the handle.
Door heat transfer coefficient – standard
When choosing an exterior door to the house, you should pay attention to thermal insulation, because it determines the heat loss and, ultimately, the amount of heating bills. According to the applicable standards, the heat transfer coefficient in the case of external doors should not exceed 1.3 W / (m2. K). Before choosing specific exterior doors , it is best to carefully assess the structure, the materials from which the door was made, as well as the appropriate combination of all elements. It is also worth remembering that the heat transfer coefficient is influenced by the correct installation of external doors, so it is worth using professional help in this area. Building standards of doors , in addition to the heat transfer coefficient, also determine acoustic insulation. The lowest permissible sound insulation should be 25 dB, which means that exterior doors suppress noise of this intensity. In the case of this parameter, it is worth it to be as high as possible, thanks to which no noise from the street will penetrate into the interior of the house or apartment, which will ensure peace and comfort for the household members.
Standards for exterior doors
The building standards of doors also specify the materials from which they can be made. Exterior doors should be resistant to installation and everyday, even intensive use. For the manufacture of exterior doors , aluminum, steel, glued wood, PVC or composite are used. Most often, however, aluminum, steel and wooden doors are made, because they provide durability and strength. The choice of specific doors should take into account the operating conditions and frequency of use. For places with high traffic, aluminum and steel doors will definitely work better. Standards for exterior doors specify the parameters that each unit must have. Door building standards are primarily aimed at ensuring the safety and comfortable use of exterior doors.
