FAQs: Commercial Windows and Doors

What certifications do DERCHI commercial systems carry?

NFRC, AS2047, CE, CSA, and ISO 9001. Glass options include IGCC/SGCC–compliant units. Over 100 patents support product innovation.

What performance ranges can I expect?

Systems are tested for air, water, and structural loads, thermal metrics (U-factor/SHGC), and acoustics (STC/OITC). Representative results include water tightness up to 700 Pa, design wind pressure up to 5 kPa, and STC in the 30–35 dB range, depending on series and glazing.

What materials and glazing configurations are available?

6063-T5 aluminium frames with thermal breaks and EPDM gaskets. Double or triple IGUs with Low-E coatings, inert gas fill, and warm-edge spacers; tempered or laminated glass where safety or noise control is required.

How is security and durability addressed?

Patented four-sided, six-point locking improves sash retention and sealing. Hardware and finishes are selected for high duty cycles, with documented maintenance plans to extend service life.

Which system types and operations are supported?

Inward/outward casements, tilt-turn, fixed, sliding and lift-slide doors, narrow-sightline sliders, and heavy-duty panoramic doors. Series are available for office, hospitality, retail, education, healthcare, and multifamily.

How do I plan for large spans and multi-track openings?

Multi-track sliders support wide clear openings and stacked panels. Verify panel width/height, glass weight, and hardware capacity; use reinforced interlocks and appropriate sill options for performance targets.

How are water and air managed at the façade?

Triple-seal designs with pressure-equalized drainage, sill pans, flashing schedules, and specified sealants. Field testing (spray/air leakage) and checklists confirm installed performance.

Can these systems integrate with curtain wall or window wall?

Yes. System windows and doors interface with storefront, window wall, and insulated curtain wall using tested transitions, anchorage details, and water-management notes.

What production capacity and delivery support are available?

A 70,000 m² automated base with high annual output supports phased deliveries, labeled pallets, and protection plans. Global logistics and local service teams align to project schedules.

What technical documentation and site support do you provide?

CAD/BIM families, CSI specs, shop drawings, installation guides, and QA/commissioning checklists. Factory-trained technicians support field measurements, training, and punch-list closure.
