Which window and door system is the most energy efficient?



“Passive design” and “energy efficiency” are now keywords for many construction projects, as well as for those looking to invest in them.

Current technologies and materials have made it possible to build carbon neutral facilities – both directly, in terms of impact on the local environment, and indirectly, through, among other things, low energy demand.

The latter can be significantly influenced by the correct choice of windows and doors.

Energy efficiency in buildings

Climate change has caused the construction industry to focus more and more on adapting to new ecological trends. This approach has now become essential for many companies in the sector and, fortunately, more and more organizations are becoming aware of it.

Thanks to external pressure on the industry, as well as innovation in construction itself, investors now have low-emission technology and environmentally friendly and easily recyclable materials (such as aluminum and wood) to be taken into account in their decisions. And because of the emphasis on “green” buildings, there is a much greater emphasis on the energy efficiency benefits in built facilities, both from a business and business perspective. final user.

Buildings constructed in recent years, especially those that can boast of meeting BREEAM and LEED certification requirements, effectively utilize all the latest eco-building technologies. They are mainly characterized by a high energy efficiency coefficient, which means that their operating costs are lower than those of installations built with the use of traditional materials.

One of the main elements taken into account in reduce energy demand is the right choice of window and door systems. What should you consider if you want to dramatically reduce operating costs?

How do you choose windows and doors that ensure energy efficiency?

Creating an energy-efficient building requires a coherent, well-structured and well-thought-out design. The architect should initially plan the structure taking into account both the needs of the end user and the environmental impact.

Windows in particular are among the most important elements affecting passive energy gain. Designing modern and environmentally friendly projects must go hand in hand with proper exposure and the use of certain specifications. For this reason, during the conceptual phase, it is important to think about:

  • Use a large amount of glazing with a southern exposure, so that the rooms are lit with lots of natural light;
  • Including the installation of a system of roller shutters or external blinds, which serve to protect the rooms against overheating in summer;
  • Application of window systems with a thermal transmittance index (g) of at least 0.5 (and better if it is between 0.85 and 0.5), while the heat transfer coefficient ( U) is not more than 1.1 watt per square meter for each degree of temperature difference [W/m2K];
  • Selection of window systems in which rare gases (neon, krypton or xenon) are used as insulation between glass surfaces:
    • Thanks to their high density, they ensure a considerably lower level of heat loss than windows insulated with nitrogen and, thanks to their acoustic properties, they give the building a reinforced soundproofing.

Aluprof, manufacturer of recycled aluminum window and door systems, offers a range of products perfectly suited to the needs of passive and energy-efficient construction.

The MB-100GFT system, recently introduced to the UK market, deserves special attention as it is dedicated to installations that wish to focus on energy protection. Using aluminum for the production of frames means that the glazed area can be much larger than in the case of PVC windows and doors. And because it is able to fill the profiles with a special insulation, the MB-100GFT has a thermal insulation index of 0.9 [W/m2K] for doors and 1.2 [W/m2K] for windows, respectively.

The MB-100GFT system is intended to be used as a store entrance and showcase on the ground floor (photo below) where, in addition to good thermal insulation, resistance to regular and daily use is also important.

Let’s build a better future

Low emissions and energy efficiency are both strongly anchored in the Aluprof British mission. Through continuous investment in improving the production line and using recycled aluminum for production, the company is focused on sustainability while maintaining high ecological standards. The brand pays the same attention to its window and door systems.

“The mission of Aluprof The UK needs to set new trends and develop solutions to the construction industry’s problems – in terms of the climate – as well as create environmentally friendly and energy efficient facilities, while reducing their carbon footprint ” , said Wojciech Brożyna. , Managing Director of Aluprof UK.

Thanks to this, it offers investors solutions that ensure adequate thermal insulation, which has a direct impact on energy savings, lower operating costs and – consequently – greater respect for the environment. natural.
