With summers across Europe becoming increasingly hot and energy prices continuing to rise, thermal comfort is no longer just a challenge for the heating season. Equally important is how effectively a building copes with high temperatures – and how much it costs to keep it cool. In this context, carefully selected windows and doors, complemented by external sun shading solutions, have become one of the most effective ways to reduce energy consumption. This approach reflects the all-in-one concept, helping not only to cut demand for air conditioning by up to 30%, but also to maintain a consistent architectural aesthetic.

Protection from the sun – before it reaches the interior

Modern aluminium windows and doors, such as MB-86N and MB-79N, provide the first line of defence against heat. Thanks to advanced thermal breaks, precisely engineered profiles, excellent sealing and the option of using different glazing units with the right performance parameters, they effectively reduce heat transfer into the building. Without high-quality windows and doors, air-conditioning efficiency drops noticeably, indoor temperatures rise more quickly, and the system has to work harder, resulting in higher energy consumption.

This barrier is complemented by intelligent sun shading systems, such as external Venetian blinds, roller shutters and screens. These take on the task of managing solar radiation, blocking and dispersing 80 to 90% of the rays before they even reach the glass. Only by combining high-quality windows and doors with appropriately selected shading systems is it possible to create a complete solution that can reduce energy consumption for cooling by up to 30%.

Why windows and doors play such a decisive role in the energy balance of a building is explained by Aluprof expert Michał Marcinowski, Director of Product Development for Architectural Systems:

We take a comprehensive approach to thermal comfort in buildings. The key lies in our window and door solutions, which we design to improve energy efficiency in line with the principles of sustainable development. But windows and doors alone are only half the story. Even greater savings can be achieved when they work together with sun shading systems. The all-in-one concept allows project owners to avoid what might be called the summer energy debt – instead of paying high electricity bills during the summer months, they invest in passive protection that continues to pay back over decades.

The all-in-one concept supporting long-term project value

For project owners, efficiency is only part of the equation. Equally important is how effectively the individual elements work together. Choosing aluminium windows and doors together with sun shading systems from a single manufacturer ensures consistency in quality, full system compatibility and a harmonious design in which all elements are perfectly matched. At the same time, it provides predictable performance parameters, which are essential for long-term cost planning and project efficiency.

MB-79N and MB-86N windows and doors deliver high levels of insulation – keeping cool air inside during the summer and reducing heat loss in winter. Meanwhile, MB-82HS lift-and-slide patio doors and MB-Skyline Type S sliding doors combine large glazed areas with excellent sealing and thermal protection. They can also be complemented, for example, by SkyTwin roller screen systems, which reduce overheating indoors and limit the amount of solar radiation entering the building, helping to maintain a comfortable temperature in summer.

The effectiveness of the all-in-one approach, combining windows and doors with shading systems, has been confirmed by research carried out by Aluprof in cooperation with Cracow University of Technology. The study showed that combining roller shutters with aluminium windows improves a building’s energy efficiency and supports the optimisation of operating costs. When lowered, the roller shutter creates an additional air layer, enhancing the insulating properties of the entire building envelope.

A building that saves energy by itself is no longer a vision of the future, but the result of a conscious project decision. Choosing modern aluminium windows and doors – durable, highly insulating and integrated with sun shading systems – means that the building begins to actively manage energy. In practice, lower cooling costs mean greater control over user comfort, more stable operating costs and solutions that support the long-term value of the project.

Ambassador of precision – Szymon Marciniak

The face of the “Let’s build a better place” campaign, in which Aluprof promotes the all-in-one concept, is international football referee Szymon Marciniak. His profile perfectly reflects the brand’s philosophy – complete control, rapid reactions and faultless decisions. Just as a referee controls the flow of a match, Aluprof solutions allow buildings to “set the rules” for the weather, ensuring thermal comfort while keeping operating costs to a minimum.
