Wood provides a unique natural touch and creates a pleasant, warm atmosphere. Quality wooden doors therefore go well with a multitude of styles, but their flawless look requires regular maintenance in the form of painting and varnishing. Aluminium entrance doors, on the other hand, are quite easy to clean and maintain. They can also be dressed in numerous wooden decors, so at first glance they are almost indistinguishable from wooden ones.
Aluminium entrance doors have numerous advantages over plastic ones, the main ones being their longer service life and better insulation. Due to its better static stability and greater strength, aluminium is better at withstanding extreme temperatures, so it is much less susceptible to bending.
This is crucial given the temperature differences between the outside and the inside, which occur in both summer and winter. Bent door leaves fit more poorly into the door frame and consequently result in poorer sealing, which results in heat loss and thus higher heating costs. Such doors must also be replaced earlier.

If you have additional wishes or needs during the configuration, you can contact our experts, who will try to incorporate them into the plan as much as possible and ensure its realisation. You can also create a completely unique entrance with the help of an architect, and our specialists will draw up a plan based on the architect’s design.
The proper measuring of the door opening is of crucial importance, so customers are advised to do it with the help of a measuring expert. For an inquiry or an indicative offer, we only need approximate dimensions, so you can wait with the accurate measurement until you make the actual order.
You can also determine the dimensions of your new entrance door yourself, which is somewhat easier in new buildings. In this case, please note that the construction opening must be 30 mm wider and 20 mm higher than the door unit. When determining the height, make sure to start from the height of the finished floor.
Read more about how to measure the opening of your entrance door yourself – both for new buildings and when renovating the entrance – in this article.
Most of the models are single-leaf entrance doors, but we can also make double-leaf doors at the special request of the customer. We can also add side lights and fanlights to the door to bring more daylight into the home while optically highlighting the entrance.
Most doors in family houses open inwards, but if you want to save space or the design of your entrance does not allow the door to open inwards, you can also choose to open your door outwards.
