UW- value 1.1

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.

  • Sill: Low aluminum threshold with a thermal insert (thermal break) that does away with the "cold bridge" and freezing along the bottom of the opening.
  • Load capacity: The wider sash profile makes it possible to build massive doors for busy passage areas.

Glazing and Infill Choices:

  • Top filling thickness: up to 48 mm.
  • Filling variants: Extra-thick double-chamber energy-saving glass units, armored glass (triplex) or designer HPL panels with high thermal insulation values.

Largest Sash Sizes:

  • Top sash width: up to 1100 mm (single-leaf) / up to 1900 mm (double-leaf with mullion).
  • Top sash height: up to 2400 mm.
  • Leaf weight: up to 140-160 kg (owing to reinforced hinges and profile depth).

Tested Performance:

  • Heat resistance value (Ro): up to 0.95–1.0 m²°C/W (varies with infill and whether the middle seal is present).
  • Noise damping (Rw): up to 40-42 dB.
  • Break-in resistance: Works with RC2 class hardware and can take anti-burglar locks with 5 pressure points.
  • Air leakage: Class 4 (top airtightness grade).

FAQs

Frequently Asked Questions about WDS Door 76

What are the exact thermal and structural specs of the WDS Door 76?

It is built on a 76 mm mounting depth with a 5-chamber layout across frame and sash. Thermal protection reaches Uw ≤ 1.1 W/(m²·K) (heat resistance Ro up to 0.95–1.0 m²°C/W), with sound damping of ≈ 42 Rw(dB) and Class 4 air leakage. A dedicated closed steel insert of 2.0 mm cross-section keeps the structure steady in extreme temperatures.

Which panel and glazing infills does the WDS Door 76 accept?

It takes infills up to 48 mm thick, which opens the door to high-insulation options:

  • Extra-thick double-chamber energy-saving glass units
  • Armored triplex glass
  • Designer HPL panels with high thermal insulation values

What is the largest WDS Door 76 sash size and weight?

The wider sash profile supports massive leaves for busy passage areas. Single-leaf width reaches up to 1100 mm (up to 1900 mm for double-leaf with a mullion) and height up to 2400 mm. Leaf weight runs up to 140–160 kg, carried by reinforced hinges and the deeper profile.

Does the WDS Door 76 threshold cause cold bridging at the floor?

No. It uses a low aluminum Termo-Umbral threshold fitted with a thermal insert (thermal break) that removes the "cold bridge" and prevents freezing along the bottom of the opening. An optional middle sealing contour (MD) further turns the door into a dependable shield against drafts and damp.

How secure is the WDS Door 76 against break-ins?

It is rated for Class RC2 / RC3 security and works with RC2-class hardware. It accepts anti-burglar locks with 5 pressure points, making it the flagship entry door for top-level protection against break-ins on country homes.

When should I choose the WDS Door 76 over the WDS Door 60 or Door 70?

Step up to the Door 76 only when you need maximum thermal and security performance:

  • WDS Door 60 (60 mm, 3 chambers, Uw ≤ 1.5): shops and offices
  • WDS Door 70 (70 mm, 4 chambers, Uw ≤ 1.3, RC2): private homes
  • WDS Door 76 (76 mm, 5 chambers, Uw ≤ 1.1, RC2/RC3): premium cottages
For smaller or budget openings the Door 60 or 70 may suffice.
