In order to satisfy the needs of our customers and to guarantee maximum functionality and thermoacoustic insulation, ALsistem has devised a fitting system that resolves all the issues related to mounting and installation.

The quality of a window is the result of several factors, not least of which is the mounting and installation. It is not something that should be improvised and should be carried out by skilled, qualified technicians.

What is window fitting?

Window fitting the mounting and installation of a window. It is a vitally important operation that, if done badly, compromises performance in terms of
thermal insulation and acoustic insulation as well as quality of life in the home.
If a window is not properly fitted, you may be exposed to the penetration of hot or cold air, water ingress and noise.

What is
Thermoposa?

Thermoposa is a project, compliant with the UNI 11673-1 standard, that resulted from the collaboration of a group of Italian, Austrian and German technicians. It is fitting method that is unique in Europe owing to the following features:

  • It only uses materials that are guaranteed for at least 10 years;
  • It has its own fitting manual which illustrates the most common fitting scenarios, designed and tested in the laboratory to ensure efficiency and performance;
  • It can be adapted to all sorts of construction sites thanks to its simplicity of execution;
  • It is carried out by qualified fitters who have obtained the Diploma of the Accademia di Formazione (Training Academy).

Correct positioning
of the window

The use of a Thermopro counter frame, fastenings with turbo screws, and high-quality seals guarantees the resistance and durability of the frame.

Insulation of the shutter box

The thermal and acoustic insulation of the insulating panels significantly improves the energy efficiency of the window.

Cutting the marble sill

Sills represent the main source of heat loss and so it is necessary to block the flow of heat between the inside and outside and prevent the formation of condensation.

Are you a window installer or designer?
