You may have heard this term before, although you’ve never really pondered over it deeply. That’s because passive construction isn’t usually a topic for casual conversations or Sunday dinners. However, if you’re building a house, or planning to do so soon, it’s essential to familiarize yourself with this concept.


Passive construction is nothing more than an approach to designing and constructing buildings that focuses on minimizing energy consumption through the use of advanced insulation, ventilation, and heating technologies. Put simply, the goal of passive construction is to create a building that consumes very little energy and sometimes even becomes self-sufficient in terms of energy. What does this mean? Primarily, significant savings.



Characteristics of passive buildings include:


  1. Well-designed ventilation: Passive buildings are designed to provide effective ventilation without the need for traditional heating and cooling systems.
  2. Proper building orientation: Designing passive buildings considers optimal orientation towards the sun to utilize natural sunlight and minimize the need for artificial lighting.
  3. Adequate thermal insulation: Passive buildings are very well insulated, including walls, roofs, and floors, to reduce heat loss through the structure.
  4. Passive heating: Passive buildings can utilize natural heat sources such as sunlight and heat generated by household appliances to warm the interior.
  5. Low energy consumption: The main goal of passive construction is to reduce energy consumption, both during building operation and in the construction process itself.


Both passive construction and passive windows are becoming increasingly popular in many regions worldwide due to the numerous benefits associated with energy savings, sustainable development, and resident comfort.


Passive windows are a crucial element in passive construction. They are characterized by very high thermal insulation, minimizing heat loss and providing excellent thermal insulation. Such windows typically feature multi-chamber profiles, special insulation layers, and triple or even quadruple glazing with low-emissivity coatings. Additionally, passive windows may be equipped with advanced sealing systems to eliminate air leaks.


  1. High thermal insulation: Passive windows are designed for maximum thermal insulation. Their construction is based on multi-chamber profiles that prevent heat conduction and minimize heat loss inside the building.
  2. Triple or quadruple glazing: They are typically equipped with triple or quadruple glazing, which further enhances thermal and acoustic insulation. These additional layers of glazing help maintain a stable indoor temperature and reduce external noise.
  3. Low-emissivity coatings: Windows are often coated with special low-emissivity coatings, which reduce UV radiation penetration and increase the energy efficiency of windows by reflecting heat into the interior spaces.
  4. Special profiles and seals: Window profiles in passive systems are designed to minimize thermal bridges and provide excellent sealing, eliminating air leakage and protecting the building interior from heat loss.
  5. Mechanical ventilation with heat recovery: Some passive window systems can be integrated with advanced mechanical ventilation systems with heat recovery. This allows for efficient use of heat from exhaled air to heat incoming fresh air, further increasing the energy efficiency of the building.
  6. Weather resistance: Passive windows are also designed to withstand various weather conditions, ensuring durability and reliability for many years.


One of the passive systems we offer is MB 104. This solution allows for the production of various architectural elements, such as windows, vestibules, shop windows, or spatial structures, characterized by excellent thermal insulation, high acoustic insulation, watertightness, and airtightness, as well as exceptional structural strength.



The profile construction in the MB-104 Passive system has been developed in two variants, SI and AERO, adapted to different requirements regarding thermal energy savings. The parameters of windows made using the MB-104 Passive system exceed current standards and regulations regarding thermal insulation, making this system an ideal solution for energy-efficient and passive construction.


Remember, the choice of windows is often a decision for years. It’s worth investing in a solution that will not only be practical and convenient but will also bring joy and significant savings over the years.
