PassiV AluClad

PHi logo mini

Our PassiV AluClad window (formerly branded Eco-clad) has been certified as a Passive House suitable component by the Passivhaus Institut, Germany.

The PassiV AluClad window combines the strength, corrosion resistance, durability and recyclability of aluminum on the outside with the aesthetic advantages of a natural finish wooden window on the interior.

The exterior frame is manufactured from aluminum alloy extruded to BS1474. The section is coated with an architectural grade polyester powder to comply with BS6497 : 1984 and BS EN 12206. The system incorporates a uPVC encased insulating thermal core. Advanced glazing options include a 24mm double glazed unit or a 52mm triple glazed unit, low emissivity glass coating, warm edge spacer bar, Argon or Krypton gas fill.

The PassiVAluClad range allows you to have the warmth, thermal efficiency and aesthetic advantages of a natural finish wooden window on the interior with a durable low maintenance aluminum exterior in a choice of attractive color finishes.
