Ușă de interior din lemn stratificat ai furnir natural, Zitrin-Q CL.1 made to order

Zitrin-Q CL.1 — interior door in laminated wood with natural oak veneer, robust 40 mm construction with fixed upper panels, designed for contemporary spaces and premium residential settings.

The Zitrin-Q CL.1 interior door positions itself as a reference solution for residential projects that prioritize durability and understated design quality. Manufactured in Germany, the series reflects a construction philosophy centered on stable materials and finishes that integrate naturally into both contemporary and classical interiors. The CL.1 line addresses homeowners seeking more than functional space separation — a presence defined by craftsmanship and refinement.

The 40 mm laminated wood structure delivers exceptional structural stability and superior resistance to moisture and temperature fluctuations. Natural oak veneers are applied to both surfaces, ensuring visual consistency and long-term durability. The laminated core distributes mechanical stresses uniformly, preventing warping and veneer lifting. The oak's characteristic grain and knots are not concealed but celebrated — each door carries its own visual identity, inherent in the wood's natural variation and authenticity.

The fixed upper panels redefine the door's visual proportions, eliminating the need for a traditional horizontal frame and creating a clean, contemporary line. This technical solution refines the aesthetic profile while facilitating installation in architectural contexts with non-standard dimensions. The 40 mm thickness ensures functional acoustic insulation for discreet room separation without requiring additional soundproofing systems. Available swing systems—hinged or pivot—can be adapted to spatial configuration and usage preferences.

The natural veneer's color and texture harmonize seamlessly with solid oak flooring, engineered parquet, or timber beams. Compatibility with minimalist furnishings and understated hardware makes it especially suitable for apartment renovations, Scandinavian-inspired residences, and contemporary interior design projects. The door integrates effortlessly in spaces with abundant natural light or limited daylight, as natural veneers require no strict color matching protocols.

Zitrin-Q CL.1 is German-certified and available in standard dimensions. Customization options include frame profile adjustment and swing system selection. Investment in this door guarantees a durable, discreet, and characterful presence in any quality residential space, with extended lifecycle and minimal maintenance requirements.

Zitrin-Q CL.1 is constructed from laminated solid wood with a total thickness of 40 mm — a dimension that ensures structural stability and sound insulation for residential interior spaces. The leaf features fixed upper panels, allowing for contemporary integration and distortion-free performance over time, even in environments with temperature and humidity fluctuations.

The finish features natural oak veneer — a noble material that patinas elegantly and develops authentic character over time, giving the door an ever-sought presence in contemporary design. Periodic cleaning with a soft, lightly dampened cloth is sufficient; natural veneers require no special treatments and preserve beautifully if direct, prolonged exposure to intense sunlight is avoided.

Zitrin-Q CL.1 — the CL.1 designation indicates a standard construction for residential interior doors, optimized for private spaces with conventional closing mechanics. For higher security requirements or installation in high-traffic areas, variants with multi-point sealing and robust hinges can be specified at order stage, depending on frame configuration and user preferences.

Yes, Zitrin-Q CL.1 accepts custom dimensioning — width, height and opening position (left/right) are adapted to your existing frame and spatial geometry. Precise measurements from an installer or designer are recommended, with correct tolerances for sealing and smooth operation; the practical upper limit sits around 1300 x 2400 mm for single laminated wood doors.

Zitrin-Q CL.1 installs onto a standard wood or MDF frame — the frame must be sized to match wall thickness (adjustable between 60–200 mm in 10 mm increments) and be plumb. Hidden hinges mount into pre-routed pockets on the door sides and are fine-tuned in situ for perfect alignment; installation requires technical skill, and for renovation cases with irregular walls, assistance from an experienced installer is recommended.

The 40 mm thickness and laminated wood construction provide good acoustic insulation for residential spaces — reducing traffic and speech sounds from adjacent areas to comfortable levels. Thermal performance depends on frame sealing (threshold and perimeter); for maximum optimization, multi-point sealing gaskets and insulated core frames are recommended, reducing thermal losses and improving the space's energy efficiency.
