Harmonized Standard EN 14351-1 & The Anatomy of High-Performance Aluminum Horizontal Sliding Windows
For commercial facade developers, architects, and quantity surveyors, procuring CE marked horizontal sliding windows is not merely a box-checking exercise—it represents verified compliance with the European Construction Products Regulation (CPR 305/2011/EU). Unlike standard sliding window assemblies prone to air infiltration and track water clogging, our engineered horizontal sliders incorporate continuous multi-cavity thermal profiles and advanced hydrodynamic weep channels.
At the structural core of our CE certified systems is extruded virgin 6063-T6 architectural aluminum alloy, delivering a yield strength exceeding 160 MPa. The thermal break barrier is achieved using Polyamide 66 reinforced with 25% glass fiber (PA66 GF25). This guarantees identical thermal expansion coefficients with the aluminum profiles, preventing profile warping or structural shear breakdown during extreme solar thermal cycles ranging from -35°C to +80°C.

Component Physics
Engineering Principles Behind Deflection-Free Sliding Operation
Traditional horizontal sliding windows have historically faced criticism for higher air infiltration compared to outward opening casements. Through our precision extrusion tooling and multi-barrier sealing matrices, our factory has eliminated traditional sliding window vulnerabilities.
SUS304 Stainless Steel Modular Dual-Tandem Rollers
Each sash is engineered with heavy-duty tandem bogie rollers housed in grade 304 stainless steel carriages with sealed precision needle bearings. This mechanism distributes sash glass weights up to 400 kg smoothly along a raised stainless steel monorail, preventing galvanic corrosion while maintaining an effortless sliding force lower than 30 Newtons.
- Tested over 100,000 continuous displacement cycles
- Self-aligning height adjustability (±3mm tolerance)
- Integrated anti-jump and anti-derailment security pins
Differential Pressure Hydrostatic Weep Systems
Standard slider drain slots backdraft under intense storm winds, forcing water back into the sill track. Our proprietary stepped drainage design introduces concealed downward-facing weep valves equipped with self-closing check flaps. Water drains automatically under gravity while exterior wind gusts pressure-seal the valve against reverse siphonage.
- Zero visible exterior drainage caps for seamless aesthetics
- Withstands 1050 Pa continuous dynamic water testing
- Internal stepped sill profile prevents reservoir accumulation
Co-Extruded EPDM & Silicone Fin Seals
Replacing standard low-density felt weatherstrips that degrade under ultraviolet exposure, our horizontal sliding profiles integrate high-density woven polypropylene brush piles with embedded central polyethylene fins, paired with co-extruded vulcanized EPDM compression gaskets at the interlocking mullions.
- 100% UV and ozone degradation resistance over 20+ years
- Continuous acoustic seal rating exceeding STC 38
- Class 4 air tightness eliminating drafts completely
Strategic Market Intelligence

Frequently Asked Questions: Global Window Procurement
Detailed answers for project developers, quantity surveyors, architects, and importers seeking authoritative clarity on custom orders, technical validation, and intercontinental shipping.
Q What exact testing reports are supplied with the CE declaration for aluminum sliding windows?
Under the EN 14351-1 harmonized standard, we supply an official Declaration of Performance (DoP) accompanied by Third-Party Notified Body test reports covering: Air Permeability (EN 12207, achieving Class 4 up to 600 Pa), Watertightness (EN 12208, reaching Class E900 to E1050), Wind Load Resistance (EN 12210, achieving Class C5 at 2000 Pa design pressure), and Thermal Transmittance Uw calculated via EN ISO 10077-1 and confirmed via guarded hot box testing.
Q How does DERCHI ensure horizontal sliding windows do not leak air in high-wind coastal conditions?
Conventional sliders leak where the interlocking vertical stiles meet. We eliminate this with structural labyrinth interlocks lined with high-density silicone-treated polypropylene barrier fins and EPDM compression cushions. Furthermore, hidden anti-lift security blocks at the upper and lower track corners physically lock the sashes inward against the perimeter seals as exterior wind pressure increases.
Q Can you fabricate bespoke profile extrusions for custom architectural facades?
Yes. In addition to our catalog of 80+ active European, North American, and Australian standard extrusion dies, we engineer custom extrusion tooling in-house. Die fabrication requires approximately 14 to 18 days, with sample profile extrusion, anodizing/coating, and corner mock-up approvals delivered to your office via courier prior to volume batch extrusion.
Q How are heavy sliding glass panels packaged to prevent transit damage during ocean freight?
Every window sash and frame undergoes an 8-stage export crating protocol: surfaces are taped with protective anti-static PE films; corners are armored with impact-resistant polypropylene guards; the unit is shrink-wrapped with waterproof vapor-barrier film; and finally secured inside fumigated ISPM-15 compliant solid plywood crates equipped with interior EPE shock-absorbing foam blocks and steel strapping bands.
Q What glass configurations are recommended for high thermal insulation and acoustic attenuation?
For balanced thermal and acoustic performance in urban or highway environments, we configure double or triple glazed insulated units utilizing: 6mm Low-E Tempered + 16mm 90% Argon Gas filled cavity with warm-edge spacer + (4mm Clear Tempered + 0.76mm acoustic PVB + 4mm Clear Tempered). This configuration easily delivers an overall thermal Uw of 1.15 W/(m²·K) and an acoustic attenuation of Rw 41 to 44 dB.
Q What are the lead times for volume OEM/ODM horizontal sliding window production?
Standard project cycles range from 25 to 35 calendar days following signed architectural shop drawings and deposit clearance. High-volume commercial contracts exceeding 5,000 square meters are produced in staggered phased batches scheduled precisely to match your container shipping matrix and on-site building construction crane schedules.
Q Do you provide remote installation guidance and jobsite hardware calibration support?
Yes. Each production crate includes detailed shop installation schematics, exploded anchor positioning drawings, and track leveling manuals. Additionally, our senior facade technical engineers provide video conferencing walkthroughs aligned with your time zone to instruct your local glazing subcontractors on perimeter expansion joint caulking, track leveling, and roller calibration.
Q Can we inspect the manufacturing facility and witness performance testing in real-time?
Absolutely. Overseas partners can tour our 180,000㎡ manufacturing complex via our 3D interactive VR showroom, or schedule a live video factory audit. Our quality control team will walk you through raw profile spectrophotometry, corner tensile testing, glass dew point testing, and on-site air/water pressure chamber test demonstrations.
