WDS Door 76 Sash — The pinnacle of door evolution. This is a designer system with hidden sash (flush-bonded sash technology). Unlike regular doors where plastic profile is visible around the panel, here the decorative panel completely covers the sash on the exterior.

Why architects choose this system:

  • Aluminum aesthetics: You get trendy monolithic design without visible seams and transitions, characteristic of expensive aluminum doors, but at PVC prices.
  • Thermal insulation Ud = 0.7: Because the panel covers the profile, total insulation thickness increases and thermal bridges disappear. This door officially qualifies for certified Passive House construction.
  • Rigidity: The panel isn't just inserted but bonded to the sash, becoming part of the load-bearing structure. This eliminates sagging even with enormous door sizes.

The ideal solution for modern villas in hi-tech and minimalist styles.

System Design Parameters:

  • Installation depth: 76 mm (increased base for maximum stability).
  • Profile construction: 5 chambers in frame and sash (optimized for thermal insulation).
  • Sealing system: Possibility of installing middle sealing circuit (MD), turning the door into a reliable barrier against drafts and moisture.
  • Reinforcement: Special closed steel frame of increased cross-section (2.0 mm thickness), ensuring structural stability even at extreme temperatures.
  • Threshold: Low aluminum threshold with thermal insert (thermal break), eliminating "cold bridge" and freezing in the lower part of the opening.
  • Static: Increased sash profile width allows manufacturing massive doors for high-traffic transit zones.

Glazing and Filling Options:

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

Maximum Sash Dimensions:

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

Certified Characteristics:

  • Thermal resistance coefficient (Ro): up to 0.95–1.0 m²°C/W (depends on filling and middle sealing presence).
  • Sound insulation (Rw): up to 40-42 dB.
  • Burglar resistance: Compatibility with RC2 class hardware and possibility of installing anti-burglar locks with 5 pressure points.
  • Air permeability: Class 4 (highest airtightness level).

FAQs

Frequently Asked Questions about WDS Door 76

How does this differ from regular WDS Door 76?

In a regular door, the panel is inserted INSIDE the profile (plastic edge visible). In the Sash version, the panel is BONDED to the profile exterior, completely covering it. This is more beautiful, warmer, and more rigid.

Won't the panel detach under Spanish sun?

No. We use industrial two-component adhesives and thermal expansion compensation technologies. The panel "floats" relative to the profile when heated but maintains airtightness.

Is this an aluminum door?

Visually it's indistinguishable from a premium aluminum door costing 2-3 times more. But inside it's warm PVC profile that retains heat better than cold metal.

Can a long handle be installed?

Yes, these doors combine perfectly with long stainless steel bar handles (Manillón) up to 2 meters long, as well as fingerprint access systems.
