Aluminum roof window FTP-V U41 APMX

pinewood-aluminumpivoting

Overview
The FTP-V U41 APMX is a pivot roof window engineered for natural daylight, controlled ventilation and safe external cleaning. The sash rotates 180° and locks in the rotated position to allow maintenance of the outer pane. Ergonomic bottom handle and precision guiding ensure smooth operation and secure closing — suitable for contemporary architectural roof applications.

Thermal and acoustic performance

• Glazing unit: U41 44 mm triple-glazed unit with two low-emission coatings, argon-filled cavities and warm TGI spacer.
• ThermoPro technology: improves thermal insulation to reduce heat loss in winter and limit overheating in summer.
• Uw coefficient: 1.1 W/m²K (standard installation); 1.0 W/m²K with dedicated EHV-AT Thermo flashing.
• Acoustic insulation: sound reduction index Rw = 36 dB.

Construction, finish and durability

• Interior finish: vacuum-impregnated pinewood with clear acrylic varnish to reveal natural wood grain.
• Exterior cladding: aluminium in anthracite (RAL 7016) for a minimalist appearance.
• External toughened glass: impact-resistant outer pane with lifetime hail warranty.
• Sustainable materials: FSC-certified wood and water-based coatings used in production.

Comfort, safety and usability

• Pivot opening with mid-height hinge for ventilation and safe cleaning.
• 180° rotation: sash locks in rotated position for external pane cleaning (locking bolt feature).
• Handle: ergonomic bottom-position handle (GREENVIEW SILVER on standard configuration); micro-opening for controlled ventilation.
• Automatic air inlet: regulates incoming air by wind strength to balance ventilation and noise.
• topSafe system: reinforced construction to increase resistance to break-in attempts and accidental opening.

Additional functional features

• Four sealing levels (4 seals) to enhance airtightness and reduce thermal bridges.
• Airtightness class: Class 4 (air permeability).
• Impact resistance: Class 3 (450 mm).
• Watertightness: Class 9A.

Notes
The U41 44 mm glazing combined with ThermoPro technology and correct installation (use of EHV-AT Thermo flashing) delivers the declared thermal performance. The product is supplied with natural pine interior finish and anthracite aluminium external cladding as standard.
