Aluminium roof window PTP-V U41 ABMX

uPVCpivotingtriple-glazed

Overview
The PTP-V U41 ABMX is a pivot roof window designed for pitched roofs, combining practical ventilation, easy cleaning and robust thermal performance. The sash operates smoothly with a mid-height hinge and an ergonomic handle. The sash rotates 180° and locks in position to enable safe external cleaning, ensuring daily comfort and user-friendly maintenance.

Energy and acoustic efficiency
The 44 mm U41 glazing unit features two low-emission coatings, argon-filled cavities and a warm TGI spacer, delivering reduced heat loss and improved summer protection. Thermal transmittance: Uw = 1.1 W/m²K in standard installation and Uw = 1.0 W/m²K with the EHV-AT Thermo flashing. Acoustic insulation: Rw = 37 dB (Ra1 = 35 dB; Ra2 = 31 dB). Flexible seals and multi-chamber profiles minimise air leakage and thermal bridging.

Aesthetics and durability
Internal white PVC finish (RAL 9003) offers high moisture resistance suitable for kitchens and bathrooms. External aluminium cladding in anthracite (RAL 7016) provides a modern architectural appearance. External toughened glass increases impact resistance and is covered by a lifetime hail warranty.
