5 principles of a passive house

Appropriate insulation

Through the use of materials in the envelope that insulate from the cold and heat, from exterior weather conditions and infiltrations of air.

No air leaks

Preventing holes and cracks in the walls, ceilings or windows that allow air to escape towards the outside.

No thermal bridging

On windows, walls and ceilings that allow the hot or cold air to escape.

Controlled ventilation system (CVS)

Which guarantees healthy indoor air, without losing the cold or heat from the inside.

High performance windows

Nowadays, four of our windows hold the Passivhaus certificate, awarded by the prestigious Passivhaus Institute of Germany. These windows meet the requirements of this building standard and enable the complete integration in the envelope of any building, thereby ensuring they are no longer a weak spot and providing a high level of insulation and energy efficiency. Their technical characteristics achieve a more comfortable interior atmosphere, since they notably reduce the presence of condensation, moisture or the formation of mould, among other advantages.

The Passivhaus PVC windows in our catalogue belong to the 301 series, 301 premium and i30 (hidden sash). The perfect window in aluminium from the RE70/ALU/C30 series, Aluplus by Refine, has also obtained this certification.

These windows have been subjected to extremely rigorous and demanding testing in terms of thermal insulation. In order for a window to be awarded the Passivhaus certification, it must have a thermal transmittance coefficient of 0.8 W/m²K and in our case, we achieve a thermal transmittance coefficient of up to 0.66 W//m²K, making them one of the best windows on the market.

When these​ 5 basic principles​ are applied in the construction of a home, a high energy consumption is no longer necessary to maintain a comfortable indoor temperature, whether cool or warm, in any building.

How is this achieved?

A passive building requires 90% less energy​ and this can be provided by our own body heat, sun, household appliances or a proper control of sunlight.

The sum of these 5 basic principles provides excellent comfort and health to all of the inhabitants of the home​​ and a significant ​​saving ​on your energy bills. Let’s not forget that, with all of this, ​​we are helping to preserve our planet.

In short, a ​passive building is a type of sustainable construction ​which focusses on reducing the energy required for its climate control as far as possible, managing to maintain a constant and comfortable temperature by optimising existing resources.

Our 3 passivhaus certified windows

RE 80/PVC/i30 PREMIUM series

  • Average Uw value = 0.6 W/(m2K)
  • Average Uf value = 0.9 W/(m2K)
  • Average Ug value = 0.5 W/(m2K)
  • Hidden sash profiles in PVC, substantially improving the field of vision, with a triple seal (with a rigid seal in the frame), protecting all of the closing points, increasing security and providing a complete all-round seal, with profiling of the maximum classification: S– II – A.
  • Steel reinforcement with Thermal Bridge Break (TBB): this system improves the insulation values without foregoing anti-rust treatment, without reinforcement in the sash, an integrated glazing system to guarantee the ideal stability of the sash.
  • 80 mm hidden sash section: This depth enables 5 insulation chambers, integrating them into an 80 mm frame with 7 chambers.
  • Full film system: The film on three sides makes it differ from other window systems, obtaining an aesthetic in coloured finishes, with a high resistance and greater stability over time, with more than 120 different films available.

RE 80/PVC/301series

  • Average Uw value = 0.8 W/(m2K)
  • Average Uf value = 1.0 W/(m2K)
    Average Ug value = 0.5 W/(m2K)
  • PVC profiles with triple seal (with a rigid seal in the frame), protecting all of the closing points, increasing security and providing a complete all-round seal, with profiling of the maximum classification: S– II – A.
  • Steel reinforcement: With anti-rust treatment, which guarantees its durability throughout the use life of the window.
  • 80 mm sash section: This depth enables 7 insulation chambers, integrating them into an 80 mm frame with 7 chambers.
  • Full film system: The film on three sides makes it differ from other window systems, obtaining an aesthetic in coloured finishes, with a high resistance and greater stability over time, with more than 120 different films available.

RE 80/PVC/301 PREMIUM series

  • Average Uw value = 0.7 W/(m2K)
  • Average Uf value = 0.9 W/(m2K)
  • Average Ug value = 0.5 W/(m2K)
  • PVC profiles with triple seal (with a rigid seal in the frame), protecting all of the closing points, increasing security and providing a complete all-round seal, with profiling of the maximum classification: S– II – A.
  • Steel reinforcement with Thermal Bridge Break (TBB): this system improves insulation values without foregoing anti-rust treatment.
  • 80 mm sash section: This depth enables 7 insulation chambers, integrating them into an 80 mm frame with 7 chambers.
  • Full film system: The film on three sides makes it differ from other window systems, obtaining an aesthetic in coloured finishes, with a high resistance and greater stability over time, with more than 120 different films available.

RE 70/ALU/911 series

  • Average Uw value = 0.84 W/(m2K)
  • Average Uf value = 1.14 W/(m2K)
  • Average Ug value = 0.64 W/(m2K)
  • PVC profiles with triple seal (through a rubber seal in the frame), protecting all of the closing points, increasing security and providing a complete all-round seal.
  • Aluminium coating on both the interior and exterior clipped onto the PVC profiles.
  • 76mm sash section: integrated into a 700 mm frame.
  • Aesthetic in finish with RAL colours, textured lacquered finishes.

New

In this same line we have created out new photovoltaic window, the window that generates energy. This new solution uses the sunlight we receive in our homes to turn it into electrical energy through some in-built components in some parts of the window. An eco-friendly, robust and profitable option, ideal for homes where solar panels cannot be fitted and who want to choose clean energy.
