CE Certified Aluminium Door With Window Manufacturers & Supplier

Authentic CE compliance for doors and windows under EN 14351-1 requires the manufacturer to issue a legally binding Declaration of Performance (DoP) tied to genuine Initial Type Testing (ITT) reports conducted by an accredited, notified laboratory. The DoP must detail the unique product type identification, the Notified Body's registration number, and clear performance ratings across mandatory parameters: wind load resistance (EN 12210), watertightness (EN 12208), air permeability (EN 12207), thermal transmittance (EN ISO 10077), and acoustic isolation (EN ISO 717-1). DERCHI supplies complete, unredacted test reports and DoP files with traceable certificate numbers for every product series.

Non-thermal break profiles feature a solid, single-piece aluminum section. Because aluminum possesses high thermal conductivity, internal frame faces become cold in winter, producing condensation, mold, and heavy interior heat loss. A thermal break profile physically splits the interior and exterior aluminum extrusions, mechanically crimping a low-conductivity structural insulating strip—such as Polyamide 66 reinforced with 25% fiberglass (PA66 GF25)—between them. This isolates thermal conduction, raising internal surface temperatures, preventing condensation, and lowering thermal transmittance ($U_f$) from over $6.0\text{ W/(m}^2\cdot\text{K)}$ down to $1.2\text{ to }2.2\text{ W/(m}^2\cdot\text{K)}$.

Yes. Over 90% of DERCHI production is engineered to bespoke order. We manufacture to metric and imperial dimensions, designing custom profile dies, specialized brickmold trims, perimeter nailing fins (for North American timber framing), or flush sub-sill drainage assemblies for European masonry and curtain-wall applications. All shop drawings must be reviewed and signed off by the client's structural engineer before production begins.

For sub-zero, high-latitude conditions (such as Canada, Northern Europe, and the U.S. Midwest), we recommend triple-glazed insulated units (IGUs): 6mm Low-E + 16mm warm-edge spacer with 90% Argon gas + 6mm clear tempered float + 16mm Argon + 6mm Low-E, delivering center-of-glass values down to $U_g \le 0.6\text{ W/(m}^2\cdot\text{K)}$. For coastal zones prone to high winds, we recommend an outer sacrificial 6mm or 8mm tempered pane, a 16mm Argon spacer, and an interior laminated impact sandwich (e.g., 6mm + 1.52mm PVB/SGP + 6mm) to withstand cyclic pressure pulses and windborne debris.

Heavy entrance and sliding doors are wrapped in PE protective film, lined with multi-layer high-density EVA shock-absorbing foam around all mitered corners, and crated inside fumigated, fully enclosed marine-grade plywood boxes reinforced with galvanized steel bands. Glazed panels are held securely on integrated internal A-frames with vacuum rubber stoppers to neutralize dynamic container harmonic vibration during ocean freight.

We apply high-performance architectural coatings certified to Qualicoat Class 2 and AAMA 2604 / AAMA 2605 specifications. For severe marine environments within 1 km of the shoreline, we recommend Fluoropolymer PVDF (polyvinylidene fluoride) liquid coatings (3-coat system, minimum 35 μm film thickness) or deep-bath architectural anodizing (25 μm, Class 1), capable of withstanding over 4,000 hours of continuous neutral salt spray (ASTM B117) without pitting, chalking, or adhesion loss.

Our standard production lead time runs between 25 and 35 calendar days following written approval of the shop drawings and deposit confirmation. For custom extruded profiles requiring new extrusion dies, add 10 to 14 days for die fabrication and sample testing. Because we operate an expansive 180,000 m² production base, we welcome both custom residential single-estate projects (MOQ ≥ 1 complete set or container partial lot) and commercial developments exceeding 50,000 m² of fenestration area.
