Komsta, as a window manufacturer, offers Aluprof systems, which are characterized by exceptional durability, high tightness, and excellent insulation parameters, supporting the implementation of even the most demanding projects thanks to precise workmanship and timely deliveries.
Aluprof systems are based on advanced aluminum profiles with a structure equipped with thermal spacers, which translates into exceptional durability, stability and excellent insulation parameters. Depending on the configuration and the selected model (e.g. MB 104 Passive), it is possible to achieve a heat transfer coefficient of Uw = 0.64 W/m²K, which allows to more than meet the most stringent requirements of modern passive and energy-efficient construction.
A wide range of systems makes it possible to adapt the joinery to different types of construction — from standard investments, through buildings with increased thermal insulation (ST, SI, AERO variants), to advanced architectural projects requiring large, stable glazing.
Komsta as a window manufacturer uses Aluprof systems, combining innovative aluminum technologies with precise quality control and many years of manufacturing experience. Thanks to this, the finished windows are characterized by repeatable quality, the highest tightness and reliability over a very long period of use, even with intensive operation.

Komsta as a joinery manufacturer has been using Aluprof's proven systems for over 30 years, creating solutions tailored to different types of investments — from single-family construction to the most demanding passive projects and B2B projects.
At Komsta, we combine the quality of Aluprof aluminium systems with production experience and rigorous production control, so that the finished windows retain their parameters in practice — not only in the technical specification.

Aluprof systems are based on aluminium profiles with installation depths from 70 mm to 95 mm. The use of technologically advanced thermal spacers ensures high rigidity and dimensional stability, which is essential for large and heavy glazing.
The applied system solutions increase the tightness and improve the thermal and acoustic insulation of the building, which is crucial in modern architecture.
Modern Aluprof windows achieve outstanding insulation parameters. Depending on the selected system (especially in the MB 104 Passive model) and the configuration of the glass package (up to 81 mm thick), it is possible to obtain a heat transfer coefficient of Uw = 0.64 W/m²K, which allows you to meet the most stringent requirements of passive construction.
The design of profiles and the use of innovative insulation materials effectively reduces heat loss, improves water and air tightness and directly affects the comfort of use of the building. In addition, aluminum windows guarantee very good sound insulation, which is appreciated both in residential and commercial buildings.
Aluprof windows made of high-quality aluminum are characterized by exceptional resistance to harsh weather conditions, including strong UV radiation, moisture and sudden changes in temperature. This material is naturally resistant to corrosion and does not require specialized maintenance, which translates into low operating costs over a very long period of time.
In combination with professional installation and precise adjustment of the fittings, the windows retain their useful properties for many years, guaranteeing complete tightness and smoothness of operation. Due to the high rigidity of the profiles, these systems are an ideal choice for structures of large dimensions, ensuring their stability and safety.
Komsta offers Aluprof systems tailored to the diverse needs of modern architecture:
Thanks to the wide configuration possibilities, these windows can be used both in single-family buildings, as well as in prestigious development investments and B2B projects.
Aluprof systems allow the realization of windows in different dimensions, shapes and configurations, which allows the production of non-standard structures tailored to the architectural vision. The windows are available in a full range of colours, including wood-like variants, which allows the carpentry to be perfectly integrated into the character of the building.
Komsta also implements the most demanding structures, such as lifting and sliding terrace doors, sliding systems and large fixed glazing. Thanks to the slim aluminium profiles, the interiors gain optimum illumination while maintaining excellent thermal and acoustic parameters.
Aluprof is one of the leading European manufacturers of aluminum systems for construction, setting standards in the field of energy-saving solutions for years. The company offers high-tech products that are used in the most demanding architectural projects around the world.
Aluprof profiles are manufactured from the highest quality aluminum alloys, which gives them exceptional durability and structural stability. The use of innovative thermal spacers and wide shaft packages allows to obtain insulation parameters that exceed standard market requirements.
These systems are based on a built-up depth of 70mm to 95mm, which, in combination with proper filling, allows you to achieve a heat transfer coefficient even at Uw = 0.64 W/m²K. Such high energy efficiency makes Aluprof windows an investment that realistically reduces the maintenance costs of the building, meeting the strict requirements of modern passive construction.
