What does the installation of timber windows look like?
Installing timber windows requires great precision and experience, which is why it is best entrusted to qualified staff. We then have the certainty that all the work will be carried out correctly. Even if we are not installing the windows ourselves, it is worth knowing what work is carried out during the installation of windows, because this knowledge may prove useful in the future.

What does the window installation technique depend on?
When carrying out the installation of a window, the type of walls in which they are to be placed must be taken into account. There are three types of wall: single-leaf walls, cavity walls with internal insulation and walls with external insulation. After examining the construction of the wall, a professional will determine in which zone the window should be fixed.
One of the increasingly popular types of window installation is so-called warm window installation, the aim of which is to obtain the best possible thermal insulation values. In particular it is carried out in energy-efficient and passive houses. By minimising heat losses, we can reduce heating costs. What is crucial here is the correct installation of the windows, and especially the precise connection of the window frame with the reveal. If this task is not carried out properly, accumulating moisture will damage the installation foam, leading to the formation of thermal bridges.
Correct installation of timber windows makes it possible to retain their full functionality, including high sound insulation and very good thermal insulation. Timber windows are durable and long-lasting, so once installed they will serve for many years.
Stages of installing timber windows
Timber windows are best installed after wet work has been completed, such as pouring floors and plastering, because timber, as a natural raw material, may absorb moisture. Before work is started the size of the window opening is checked (the reveal should be 2 to 3 cm wider and 3.5 to 5 cm higher than the frame), and then holes for dowels are prepared or installation anchors are fixed. In order to fit the window correctly, supporting and spacing blocks are placed in the opening. Once these tasks have been completed, the time comes to fix the window in the reveal.
The next step is sealing the window system. The frames of the fitted window sashes are protected with tape, and then polyurethane foam is placed in the gap. After the insulating material has hardened, the excess is gently removed. The final stage of the work is sealing the window around its perimeter with silicone.
