Combining heavy-duty polyamide thermal insulation, seamless floor integration, and expansive panoramic glazing capable of supporting sashes up to 400kg with fingertip glide operation.
Integrated multi-track stacking mechanism with integrated stainless insect mesh, engineered specifically for Mediterranean indoor-outdoor patio transitions.
Features robust German-style leverage hardware and high-grade EPDM sealing gaskets, delivering certified Class 9A water impermeability under driving rain.
Designed for luxury villas along the Tyrrhenian and Adriatic coastlines, hiding sashes into concealed wall pockets to open living rooms entirely to sea views.
Reinforced 2.0mm-3.0mm primary wall thickness extrusions that accommodate oversized glass units up to 3.2 meters in height without deflection.
Integrated with concealed smart motors compatible with KNX and standard Italian home automation systems, offering quiet motorized lifting and gliding.
Ultra-narrow interlock mullion of just 28mm to 35mm sightline, offering uncompromised structural integrity while maximizing solar gain for alpine environments.
Multi-cavity polyamide PA66 thermal struts delivering overall Uw values down to 1.1 W/(m²·K), fully compliant with Italian Zona Climatica E & F regulations.
Built with reinforced anti-lift mushroom cams, laminated safety glazing, and multi-point perimeter compression locks meeting European RC2/RC3 burglar resistance.
Why Italian architectural firms and general contractors systematically favor Lift and Slide engineering over standard in-line sliding systems for large structural openings.
Unlike standard sliding doors relying on friction-prone mohair brush seals that degrade rapidly under Mediterranean UV, lift-and-slide mechanisms physically lower the multi-hundred kilogram sash onto perimeter EPDM gaskets. This establishes an airtight seal achieving Class 4 air permeability under EN 12207.
DERCHI's recessed sub-floor threshold design complies strictly with Italian architectural barrier laws (Legge 104/92 & DM 236/89). The thermal-break aluminium floor track integrates seamlessly flush with internal parquet or external porcelain stoneware, supplemented by hidden stainless drainage gutters.
Leveraging internal mechanical torque reduction gearboxes, a 180-degree rotation of the ergonomic solid aluminium handle activates twin stainless steel tandem rollers. This levitates glass sashes weighing between 300kg and 400kg by 6mm to 8mm, reducing friction resistance to under 15N for child-friendly gliding.
From the freezing winter winds of the Dolomites to the saline sea breezes of Sicily, DERCHI customizes profile alloys, thermal breaks, and surface finishes for Italy’s diverse geography.
In regions such as Trentino, Lombardy, and Piedmont, our doors utilize 34mm-45mm multi-cavity PA66 thermal struts and triple-glazed argon units with warm-edge spacers to easily satisfy strict CasaClima energy efficiency certifications and prevent interior condensation.
Severe marine winds carrying corrosive sodium chloride require superior material defense. We specify Qualicoat Seaside certified powder coatings (60-80μm) or 25μm architectural anodizing paired with 316-grade marine stainless steel rollers and fixings.
Preserving the architectural heritage of stone villas and rural farmhouses requires ultra-slim profiles with realistic sublimation woodgrain textures or deep antique bronze/manganese hues that harmonize with strict Soprintendenza heritage guidelines.
Urban acoustic pollution demands high Rw sound damping. Using asymmetric acoustic laminated glass units (e.g., 6+0.76PVB+6 / 16Ar / 44.2 Silence), DERCHI doors deliver sound attenuation up to 43dB, shielding luxury urban residences from metropolitan noise.
Analyzing key structural shifts in Italian fenestration: tax incentives, minimalist optics, and EU sustainability roadmaps.
The Italian national building energy code (Decreto Requisiti Minimi) has continuously elevated the thermal baseline for windows and doors. With building renovation incentives driving thermal retrofits, DERCHI's custom-engineered thermal break lift-and-slide doors meet the strictest transmittance levels (Uw ≤ 1.3 W/m²·K in Zone E), qualifying projects for fiscal deductions.
Italian interior designers and luxury home buyers increasingly reject chunky framing. The trend demands hidden outer frame profiles concealed behind perimeter plasterboard, coupled with slender 28mm central vertical interlocking profiles that dissolve the boundary between indoors and manicured Mediterranean gardens.
In accordance with European Green Public Procurement (CAM - Criteri Ambientali Minimi), the Italian market prioritizes fenestration with high recycled aluminium billets. DERCHI adopts clean extrusion practices, utilizing primary 6063-T6 alloy combined with recycled content to deliver high dimensional stability with a minimal carbon footprint.
With more than 25 years of engineering manufacturing, DERCHI operates out of Foshan, Guangdong as an internationally verified producer of high-performance architectural systems. Certified under ISO 9001, CE, AS 2047, and NFRC standards, we serve general contractors, property developers, and window fabricators throughout Italy.
Fully automated CNC extrusion cutting, high-precision milling, corner crimping, and computerized glazing facilities capable of processing commercial-scale multi-unit developments and bespoke single villas on tight deadlines.
Our dedicated engineering team delivers shop drawings, static wind load calculations, glass thickness analyses, and sectional thermal bridge simulations directly tailored to your Italian site permits.
Doors are packaged in fully reinforced plywood crates with moisture barriers and corner protective profiles, shipping directly to primary Italian container terminals including Genoa, La Spezia, Naples, and Trieste with complete customs declaration paperwork.
Addressing regulatory certifications, customs tariffs, thermal verification, and installation support for commercial and residential procurements.
Yes. All our exterior door and window systems conform to the European harmonized standard EN 14351-1. We supply the full Declaration of Performance (DoP), covering water tightness, air permeability, wind load resistance, and acoustic insulation values required by Italian building authorities (Genio Civile) and project surveyors.
Absolutely. For cooler climates such as Lombardia, Veneto, and Piemonte (Zona E, maximum limit Uw ≤ 1.30 W/m²·K), we specify 6063-T6 thermal break profiles with multi-chamber Technoform polyamide strips (PA66GF25) and low-E triple glazing (Ug down to 0.6 W/m²·K) with warm edge spacers, easily driving the total frame and glass Uw value below 1.1 W/m²·K.
Our lift and slide systems feature specialized flush bottom tracks that recess into the finished floor screed. The visible step height is less than 15mm or completely flush (Soglia Zero), fully matching Italian accessibility regulations (D.M. 236/89) while providing integrated perimeter drainage channels to discharge heavy driving water outward.
Shipments to Italy can be arranged under CIF or DDP terms depending on your business entity. Under typical CIF terms to Genoa or Naples, your local Italian customs broker (spedizioniere doganale) handles import customs clearance under HS Code 761010 (aluminium doors and windows), applying the EU common customs tariff and 22% Italian IVA (or eligible reduced 4%/10% VAT for construction/renovation).
Yes. We offer the full spectrum of RAL Classic powders (including popular Italian architectural choices such as RAL 7016 Anthracite Grey, RAL 9005 Jet Black, and RAL 9010 Pure White) using Qualicoat-certified polyester powders. Realistic vacuum heat-transfer woodgrain textures (Walnut, Oak, Cherry) are also produced in-house with exceptional UV resistance.
Each order is dispatched with comprehensive exploded-view CAD assembly drawings, multi-lingual installation step-by-step manuals, and high-definition video walkthroughs. Our senior technical engineering team is available for real-time video conferencing during critical site installation phases to assist your local posatori (window installers).
