WDS Door 76 — An impregnable fortress with elegant design. This is the most capable and warmest entry system in the WDS range. It's made for those who refuse to compromise between the security of a steel door and the thermal insulation of a PVC one.
Why it's the best choice for a private home (Chalet):
- Wall-level energy efficiency: With its 76 mm width and 5 chambers, the door reaches a Ud = 1.1 W/m²K heat transfer coefficient — warmer than 90% of entry doors installed in Spain.
- RC2/RC3 Security: Heavy closed reinforcement (2 mm) plus compatibility with anti-burglar hardware (Winkhaus/Roto) let the door stand up to forced-entry attempts.
- Design: The sash is built for thick designer panels (up to 48 mm) that can mimic wood or concrete or carry stainless steel inserts.
An investment in your family's peace of mind and your home's prestige.
