WDS 76 MD — Premium-segment technologies accessible to everyone. This is our best-selling system because it offers elite German window characteristics (76 mm depth + middle gasket) at standard segment prices.
Two main trump cards of this system:
- MD System (Mitteldichtung): The presence of a third sealing circuit in the center of the frame creates a "dry chamber" for hardware. Metal mechanisms don't contact humid outdoor air, which is critical for coastal Spanish housing (salt corrosion protection).
- Trendy design: Unlike classic rounded forms, WDS 76 has sleek angular edges. This geometric style fits perfectly into modern interiors, lofts, and new Madrid developments.
If you're choosing between AD and MD versions, we strongly recommend MD. The price difference is minimal, but comfort level and hardware lifespan are significantly higher.

- Hardware protection: The middle gasket creates a "dry" chamber for hardware, preventing mechanism corrosion from condensation or precipitation.
Glazing Options:
- Maximum filling thickness: up to 48 mm.
- Efficiency: Allows use of extra-wide double-chamber glass units with 16-18 mm spacers, minimizing heat loss.
Maximum Structure Dimensions:
- Maximum sash width: up to 1100 mm.
- Maximum sash height: up to 2400 mm (thanks to 76 mm profile rigidity and 1.5–2.0 mm reinforcement).
Certified Characteristics:
- Thermal resistance coefficient (Ro): up to 1.02 m²°C/W (with appropriate glass unit).
- Profile thermal insulation (Uf): ~1.1 W/m²K.
- Sound insulation (Rw): up to 46-48 dB (middle sealing circuit works as acoustic damper).
- Air permeability: Class 4 (highest per DIN EN 12207).
- Water tightness: Class E1050 (withstands storm rain pressure).

FAQs
Frequently Asked Questions about WDS 76 MD (76 mm)
Is the MD version worth the extra cost?
Definitely yes. The price difference is minimal (about 5-7%), but you get a window of a completely different airtightness class. The third circuit is the standard for quality modern housing.
Is this window suitable for a bathroom?
Perfectly. Thanks to high thermal insulation (6 chambers + 3 gaskets), the inner frame surface stays warm, preventing condensation and mold in humid rooms.
What color is the gasket?
The standard white version comes with a light gray gasket that visually expands the window. For laminated windows (anthracite, wood), we use black or caramel gaskets for color harmony.
Can concealed hinges be installed?
Yes, the WDS 76 MD system is fully compatible with concealed hardware. This emphasizes the window's modern design — no visible hinges, only clean lines.
How narrow is this window's frame?
The "frame + sash" combination height is only 116 mm. This is one of the lowest figures in its class, ensuring maximum daylight enters the room.
How much can be saved on heating with WDS 76 MD windows?
The triple sealing system combined with 6-chamber profile and energy-saving glass unit reduces heat loss through windows by 40-50% compared to old aluminum frames. In Spain's climate, this means savings on air conditioning in summer and heating in winter — up to €200-300 per year per apartment.
