Aluminum roof window FPU-X MAX P50 AUMX

pinewood-aluminumtop-hung

Product overview
GREENVIEW FPU-X MAX P50 AUMX is a roof window engineered for year-round comfort, combining versatile ventilation with high thermal and acoustic performance. It offers two independent opening systems (top-hung and pivot) to enable controlled airflow, safe cleaning of the outer pane and convenient daily use.

Key functions

• Two independent opening modes: top-hung (sash raises up to 45° for ventilation and view) and pivot (180° rotation for safe external pane cleaning).
• preSelect® switch on the frame to change sash mode between top-hung and pivot without opening the window.
• Bottom sash handle with two micro-ventilation positions for controlled air exchange.
• Special locking bolt secures sash in the fully rotated 180° position for safe maintenance.

Glazing and acoustic performance

• Glazing unit: P50 triple-glazed unit, 44 mm thickness.
• Glazing composition: toughened outer pane, laminated inner pane (P2A), argon fill and additional acoustic interlayer for improved sound insulation.
• Thermal transmittance (Uw): 1.0 W/m²K in standard installation; Uw = 0.9 W/m²K when installed with EHV-AT Thermo flashing (thermoPro technology).
• Sound insulation: very good sound reduction index Rw = 40 dB (reported Ra1 = 39 dB; Ra2 = 35 dB for specific configurations).
• Outer pane: toughened glass with lifetime hail warranty (subject to warranty terms).
• Easy-to-clean coating on outer glass to reduce soiling and simplify maintenance.

Materials, finish and aesthetics

• Main material: vacuum-impregnated pinewood sash/frame for moisture resistance and dimensional stability.
• Internal finish: white polyurethane varnish (close to RAL 9003) — smooth, waterproof surface suitable for humid rooms.
• External cladding: aluminium in anthracite (RAL 7016) developed with an industrial design institute; other colour options referenced (black RAL 9005, grey-brown RAL 7022).
• Lacquer: three coats of polyurethane lacquer applied to interior surfaces.

Security, durability and additional systems

• topSafe reinforced construction to increase resistance to forced entry and accidental opening.
• Durable design and glazing choices to support long service life; internal laminated glass reduces injury risk on breakage.
• Environmentally conscious: manufactured from FSC-certified wood and finished with water-based coatings where specified.

Operation, control and compatibility

• Control: manual operation via bottom handle; micro-ventilation positions available.
• Solar power supply: not applicable for the standard manual version.
• Recommended accessories and installation products: original GREENVIEW/FAKRO flashings are required for correct installation; compatibility with EHV-AT Thermo flashing for best thermal performance.

Installation guidance

• Installation location: rafters or battens.
• Supported installation depths: J, N, V (use original installation accessories as required).
• Roof pitch range: 15°–55°.
• Proper flashing selection is mandatory for correct installation and to achieve the declared Uw.

Maintenance and cleaning

• Pivot 180° position with locking bolt enables safe, independent cleaning of the outer pane without roof access.
• Easy-to-clean coating reduces dirt build-up; natural rain and sunlight assist cleaning.
