Aluminum roof window FDP-X P50 APMX

pinewood-aluminumpivoting

Overview
The FDP‑X P50 APMX is a pivot roof window with a lower transom that increases daylight while preserving a single integrated frame. Its raised pivot axis and guided sash ensure smooth manual operation and safe external cleaning up to 180°. The unit combines high acoustic and thermal performance with minimalist exterior aluminium cladding.

Key functional benefits

• Raised pivot axis with guided sash for stable movement and ergonomic use; 160° locking position for safe cleaning.
• Lower transom with additional glazed pane to boost interior illumination without merging two separate windows.
• Lower-handle position for natural operation and micro-ventilation; wider units use two handles for easier handling.
• Locking bolt secures the sash at rotated positions (up to 180°) enabling safe external cleaning without roof access.

Energy and acoustic efficiency
Equipped with the P50 glazing unit and thermoPro frame technology, the window delivers year-round thermal performance and improved acoustic comfort. Installation options and sealing reduce thermal bridging and air leakage.

Glazing and insulation highlights

• P50 triple-glazed unit, 44 mm total thickness, with easy-to-clean coating and acoustic film.
• Uw: 1.1 W/m²K (standard installation); 1.0 W/m²K with EHV‑AT Thermo flashing (thermoPro).
• Sound reduction Rw = 37 dB; additional acoustic film and laminated P2A inner pane further improve noise attenuation.
• Toughened outer pane for impact resistance and laminated inner pane (P2A) for enhanced safety.

Aesthetics and durability

• Interior finish: vacuum‑impregnated pine with clear acrylic varnish that enhances natural grain and durability.
• Exterior cladding: aluminium in anthracite (RAL 7016) for a minimalist look; alternative colours available.
• Water‑based coatings and two lacquer coats on the interior provide long‑lasting finish.
• No air inlet in the cladding improves airtightness and acoustic performance.
