Energy costs are rising significantly, while in many cases, energy production still relies on inefficient sources. That’s why it’s essential to seek solutions that ensure energy efficiency while requiring minimal energy input. Our Passive House certified products are the answer — holding the German Passivhaus Institut certification, the world standard for passive building performance.
What is a passive house?
A passive house is a building designed for outstanding energy efficiency. It consumes minimal energy, retains heat exceptionally well, and prevents heat loss to the greatest extent possible. As is well known, a substantial amount of heat escapes through the roof and windows. That’s why Reynaers Aluminium offers top-quality products certified by Passive House, guaranteeing maximum thermal performance and comfort.
The 5 key principles of energy efficiency
- Premium-quality thermal insulation
- Triple-glazed windows
- Elimination of thermal bridges
- Heat recovery ventilation
- Airtight building envelope
Buildings that meet these five criteria — whether residential or public — achieve exceptional energy efficiency and are classified as Passive Houses. They maintain comfort using minimal heating energy.
What makes Reynaers Aluminium passive house solutions stand out?
At Reynaers Aluminium, we provide the highest-performing systems designed for passive construction. Their reliability is confirmed by official certification.
Our range includes:
Masterline 8 High Insulation + panel doors
A series of robust, highly insulated doors that deliver both security and superior thermal performance. They fully meet the strict requirements of Passive House design, rated Class 8 durability. Each door can be customised with features such as low thresholds or threshold-free designs for accessibility.
Masterline 10 High Insulation + windows
Combining practicality with aesthetics, these triple-glazed systems offer exceptional thermal insulation and weather resistance — preventing heat loss even in extreme climate conditions, while maintaining indoor comfort.
ConceptWall 50 High Insulation
A façade and curtain wall system enabling fast construction and Passive House-level energy performance. The system can also be equipped with solar shading, which supports natural cooling in passive homes.
ConceptWall 60 High Insulation
A high-performance curtain wall system designed for wind-exposed locations where maintaining internal warmth is critical. Its reinforced aluminium profiles and larger glass supports provide outstanding resistance to wind, water, and air leakage. By integrating PET foam and aluminium rods, the system achieves exceptional insulation while allowing large glass surfaces for light and openness.
Sustainable solutions with HiFinity High Insulation
When designing sliding doors or patio systems, it’s important to choose eco-friendly solutions. The HiFinity High Insulation system combines high-grade aluminium profiles with triple glazing, achieving both elegant design and top-tier energy performance. It ensures excellent resistance to air, water, and wind, with thermal insulation Uw = 0.8 W/m²K. Maximum vent opening height: 4000 mm, and width: 3500 mm. It also includes hidden drainage and a flush water channel, ensuring effective water management without the need for visible thresholds. Buildings equipped with these systems reach the highest levels of energy efficiency, fulfilling the Passive House standard. Additionally, other systems in our range — such as HiFinity High Insulation and MasterPatio High Insulation — though not officially certified, also help achieve Passive House-level performance.
