    TROCAL 76 double seal REGEL-air 76

    Passive house WA-15/2

    In the passive house variant complying with ift guideline WA-15/2, the reinforcing chambers in both the sash and the frame were foam filled with proEnergyTec. This technology achieves the highest thermal insulation values and can be recycled easily at a later date.

    • TROCAL 76 double seal system, passive house suitability complying with ift guideline WA-15/2.
    • Five chamber design with 76 mm installation depth.
    • Requirements for passive house compatible components: Uf < 0.96 W/(m2K) and Uw ≤ 0.8 W/(m2K).
    • The combination with AluClip Pro and proEnergyTec exhibits a Uf value of 0.93 W/(m2K).
    • AluClip Pro takes over a static function in the sash, making steel unnecessary.
    • proEnergyTec – this technology involves foam filling the chambers inside the profile for better thermal insulation.
    • Triple glazing up to 44 mm thick.
    • Elegant aluminium design: painted, powder finished, or anodised – virtually unlimited colour potential.

    Product Description

    The concept behind a passive house works only with a refined thermal insulation that limits the annual heating needs to 15 kWh per square metre of living space. This allows a building to be heated alone from passive energy sources without the need for a separate heating system. One of the most important components here is the window system. The slender profile sight lines presented by TROCAL 76 with the aluminium cover not only allow a modern design with large glazed areas, but also increase solar heat gains.

    The passive house institute ift in Rosenheim calculates the thermal insulation value for the PVC-U window frame in accordance with DIN EN ISO 10077-2. The condition here is a value Uf less than 0.96 W/(m²K). Ultimately, though, it is not solely the Uf value that decides the passive house suitability of a window, but also the Uw value, i.e. the thermal insulation values for the whole window. This must be ≤ 0.8 W/(m²K).

    Thanks to the two upgrade technologies AluClip Pro and proEnergyTec, the double seal system TROCAL 76 exhibits a Uf value of 0.93 W(m²K), fulfilling precisely these passive house requirements under the ift guideline WA-15/2.

    TROCAL 76 AluClip Pro gives you the best of two worlds: PVC-U and aluminium in the one innovative system. PVC-U provides the optimal thermal and sound insulation in addition to functional reliability. Aluminium presents a convincing elegance, the best weather resistance, and a wide range of colours. Yet another advantage – the aluminium takes over the load bearing functions, so no steel reinforcements are needed in the window sash.

    In the passive house variant complying with ift guideline WA-15/2, the reinforcing chambers in both the sash and the frame were foam filled with proEnergyTec. This technology achieves the highest thermal insulation values and can be recycled easily at a later date.

    Our greenline principle: energy efficient window systems, lead free stabilisers in virgin material, and intelligent recycling concepts provide that extra sustainability.

      This intelligent solution keeps harmful mould out of your living space. REGEL-air 76 can be installed either horizontally above the window or vertically next to it, i.e. in the invisible area of the PVC-U window. In addition, it is easy to clean.

      • Regulates indoor humidity and minimises risk of harmful mould.
      • Constant, uniform supply of fresh air.
      • Ventilates in closed windows as well, and invisible on both the inside and outside.
      • For vertical and horizontal installation.
      • Easy to clean, and quick and easy to install.
      • Easy to retrofit, so ideal for windows that have already been installed.
      • Tested sound insulation up to 43 dB (STC 4).
      • Tightness against driving rain and air passage in accordance with DIN and EU standards.
      • DIN 1946-6 ventilation.

      There are a large number of cases where the conventional ventilation methods are inadequate, e.g. when you are not at home. This also applies to weekend and holiday homes. Here the KÖMMERLING ventilation system REGEL-air 76 provides for fresh air – also without active ventilation. The KÖMMERLING ventilation system is the perfect solution for a healthy indoor climate at all times, also when the windows are closed.

      • Constant, uniform supply of fresh air.
      • Minimises high air humidity and the risk of mould.
      • Simple retrofit.
      • Integrated in the outer frame rebate, so invisible from the inside and outside when the window is closed.
      • Easy to clean.
      • Tested sound insulation up to 43 dB (Class 4).

      INNOVATIONS IN OPERATION

      • The “Free” insect screen functions with a caterpillar without bottom guide! It does not gather water and dirt, not dangerous for tripping on it!
      • The “Free” insect screen gives a solution to the dangerous unpredictable opening of the screen (prohibited by EC directives) as it stops at any point leaved.
      • The caterpillar forces the insect screen “Free” to work always parallel to the wall, not allowing the mesh to roll wryly or to get creased and even ripped!
      • The “Free” insect screen is manufactured with quality Fiberglass mesh; a material that will not corrode or burned (fulfills all the specifications of fire safety)!
