Table of contents

It is said that the door is the business card of the house, so it is worth investing in a solid and durable home entry door. Exterior doors should not only blend aesthetically with the facade of the building, but also have the right parameters to ensure safety and energy efficiency. What should I consider when choosing an exterior door for my home?

Technical parameters of doors – what to pay attention to?

When choosing an exterior door, one should be guided not only by aesthetic considerations, but also by technical parameters that determine the functionality of the entrance door in question. What parameters should be taken into account? First of all, it is important to pay attention to the dimensions of the door, burglary resistance, heat transfer coefficient, sound insulation and the material of the house entrance door. The minimum dimensions of external doors allowed by law are 90 cm wide and 200 cm high. As a standard, you can find doors with a height of 205 cm or 210 cm. The dimensions of the door are important information, as they require the creation of a sufficiently large door opening at the initial stage of construction work. The resistance to burglary depends on the soundness of the door and the door’s multi-point locking system. The degree of protection against burglary is determined by the class, according to European standards. There are 6 classes, where 1 is a standard door resisting physical force, and 6 refers to armored doors. The front door of a house should have 3-4 class, and for apartments in a block of apartments, 1 and 2 class is enough.

Thermal and acoustic insulation of exterior doors – why is it important?

The thermal and acoustic insulation of exterior doors is important because it can help create a comfortable home environment. Thermal insulation is determined by the heat loss coefficient, which for exterior doors must not exceed 1.3 W/(m2*K) for the entire structure. The lower the parameter, the less heat escapes from the house, which can be reflected in heating bills. As for sound insulation, it protects against outside noise getting in and should be in the 30 – 40 dB range. Thermal and acoustic insulation is also influenced by the proper installation of the door and the careful protection and insulation of any irregularities. A good exterior home door is therefore able to separate your home from the outside world, providing a safe and comfortable space.

Of what material is the exterior door?

Home entry doors can be manufactured from wood, steel, PVC, or aluminum. Each of these types of doors differs in the properties that determine their use, as well as in price. Most often when choosing an exterior door we are guided by budget, nevertheless it is worth considering all options. The cheapest and most popular are PVC doors. They are characterized by a low coefficient of heat loss and a variety of colors, so it is very easy to match them with other elements of window and door frames. Wooden exterior doors are slightly more expensive, but are characterized by very good thermal insulation. Wood is also a versatile finishing material that adds character. Aluminum doors are the most expensive, and are mainly used in commercial buildings due to their fairly high heat loss rate. Recently, however, more and more models for home use are being developed that feature very good thermal insulation. Their advantages are aesthetic qualities and the possibility of combining them with other elements of the window joinery.
