Sash design
We offer sashes that are offset or semi-offset from the frame or that sit flush. Depending on the chosen model, the interior edges can also be more angular or curved.
With a modern, insulating uPVC core that shows on the inside, externally clad by a protective and durable aluminium shell, our aluminium uPVC French doors are a real all-rounder. Ideal for balconies, terraces, and ground floors alike, with their strong yet slim frames and large glazed surfaces, light can stream in while long-lasting performance is a given. Thanks to a fixed or tilt and turn opening mechanism, the doors can also provide secure and versatile ventilation for a well-aired interior. To learn more about the technical details and how our products can be individually customised just read on or contact the team.
The Key Benefits
- Low maintenance: with its high durability, aluminium cladding needs little upkeep. Similarly, the sleek interior can be easily wiped clean if necessary.
- Excellent insulation: thanks to the precisely engineered core of our uPVC frames and profiles featuring three gaskets, these doors provide excellent soundproofing and thermal performance – we even offer two Passive House certified models.
- High impact resistance: given their strong, anti-rust metal exterior, the doors provide excellent break-in protection and effectively withstand high winds.
Glass seal
The glass seal ensures watertightness between the glazing and the sash that encases it. The weather-resistant aluminium shell with welded corner joints.
Reinforcement
Depending on the model, a steel or energy-saving carbon fibre reinforcement fully strengthens the structure.
Chambers
A varying number of insulating chambers that trap dense air slow heat loss.

By combining two materials, the colours for the exterior and interior sides can be chosen separately. The exterior aluminium shell is powder-coated, with a choice of matt, metallic, or fine-textured finishes.

uPVC–Aluminium Balcony Doors and Their Benefits
Balcony doors made of uPVC–aluminium offer an ideal combination of thermal insulation and durability. The uPVC interior provides excellent thermal insulation thanks to modern multi-chamber profiles, helping to reduce energy costs. The external aluminium layer offers reliable protection against weather, attempted break-ins, and increases the lifespan of the door. In addition, these balcony doors are particularly low-maintenance, as aluminium is weather- and corrosion-resistant.
In terms of price, they are more expensive than pure uPVC doors but more affordable than fully aluminium models. They fall into the mid-price segment and offer excellent value for money. Thanks to their robust aluminium exterior, they are more durable than standard uPVC doors while still being more cost-effective than aluminium doors. Combined with modern glazing, they meet high energy-efficiency standards and can achieve passive-house-compliant U-values of up to 0.73 W/(m²K).
All our products are custom-made and are therefore available in various opening types. All models are available with both tilt-and-turn and standard hinged functions. If you require a space-saving opening or wish to glaze a large area, we recommend our patio doors with parallel-slide-tilt, lift-and-slide, or folding-slide functionality.
