Technical Whitepaper Insights
Engineering Sliding Windows for the Unique Climate of Mecca (Makkah)
Designing fenestration for the holy city of Mecca demands strict structural physics: confronting surface temperatures surpassing 65°C, high-velocity sandstorm abrasion, and acoustic pressures generated by millions of pilgrims.
Combating the Heat Island Effect
Makkah experiences extreme solar radiation with summer temperatures regularly exceeding 48°C. Our fabrication incorporates high-grade polyamide PA66 GF25 thermal breaks that decouple interior and exterior aluminium profiles, eradicating conductive thermal bridge effects and slashing HVAC chiller loads across high-rise hotels.
Hermetic Airborne Dust & Sand Sealing
Desert shamal winds carry ultra-fine quartz silt that destroys standard sliding tracks. We integrate elevated stainless-steel sill tracks paired with dual-density multi-lip EPDM vulcanized weatherstrips and fine mohair brush seals, preventing particulate bypass, rail jamming, and air permeability leakage.
35dB to 48dB Acoustic Attenuation
The urban center surrounding the Holy Mosque remains active 24/7. Providing sound isolation in residential towers and hospitality units requires multi-chamber acoustic insulated glass units (IGU) utilizing varying glass sheet thicknesses (e.g., 6mm Low-E + 12Ar + 8mm clear laminated with 0.76mm acoustic PVB) to cancel out airborne resonance.

Analyzing regulatory transformations, sustainability benchmarks, and modern architectural shifts driving fenestration procurement in the Western Province.
Enforcement of Mostadam & Energy Codes
With Saudi Arabia’s stringent enforcement of the Saudi Building Code (SBC 601/602) and Green Building Rating System (Mostadam), commercial developers in Mecca can no longer utilize non-thermal aluminium extrusions. Building envelopes must maintain low overall thermal envelope U-values, driving demand for our 24mm-34mm polyamide-insulated assemblies.
Minimalist Profiles with Massive Glazing Spans
Modern Islamic contemporary architecture is transitioning away from cluttered multi-mullion windows toward narrow-frame sliding systems. Architects in Mecca are demanding ultra-slim interlocking sightlines (down to 20mm-26mm) that maximize natural illumination while utilizing argon-filled double Low-E units to prevent solar heat intrusion.
Factory Pre-Fabrication & Fast-Track Delivery
Short construction seasons between pilgrimage windows impose strict contractor schedules. Sourcing pre-assembled, modular sliding systems manufactured under strict ISO 9001 factory environments eliminates the high failure rates and on-site errors associated with local manual assembly shops in Mecca industrial zones.

Frequently Asked Questions by Saudi Engineers & Contractors
Direct technical responses addressing common engineering questions regarding the import, performance testing, and installation of aluminium sliding window systems in Mecca.
How do DERCHI thermal break sliding windows withstand the extreme heat of Mecca?
Our Mecca-grade sliding window profiles utilize extruded architectural 6063-T6 aluminium separated by 24mm to 34mm PA66 GF25 (polyamide with 25% glass fiber reinforcement) thermal break struts. This structural barrier breaks the continuous metal conduction between the blistering exterior (often exceeding 60°C on direct surface contact) and the chilled interior. When paired with our high-performance double or triple insulated glass units (featuring soft-coat Low-E layers and warm-edge spacer bars), our systems comfortably deliver Uw-values below 1.6 W/m²·K, drastically reducing air conditioning energy waste and complying with Saudi SBC 601 energy conservation mandates.
What engineering provisions prevent sand and dust accumulation in the sliding tracks during shamal storms?
Standard sliding windows fail in the Hijaz region when wind-blown quartz silt infiltrates bottom tracks, grinding against nylon rollers and causing track binding. We engineer our Mecca window profiles with raised, stepped stainless-steel track inserts and integrated gravity flap weep holes that prevent wind pressure backdraft while allowing micro-sand to self-evacuate. Furthermore, our sliding sashes incorporate multi-lip EPDM vulcanized sealing fins combined with high-density, silicone-treated finned brush seals along all four perimeters, achieving hermetic Class 4 air-infiltration resistance under EN 12207.
Can your products satisfy Saudi Arabian SASO and SABER certification requirements for customs clearance at Jeddah Port?
Yes. Guangdong Dejiyoupin Doors and Windows Co., Ltd. routinely exports high-volume fenestration packages into the Kingdom of Saudi Arabia. We maintain active compliance databases for SASO (Saudi Standards, Metrology and Quality Organization) technical regulations. Our team assists clients by registering products directly via the SABER electronic platform, generating both the Certificate of Conformity (PCoC) and Shipment Certificate of Conformity (SCoC). Complete mill certificates for 6063-T6 alloys, mechanical test reports, structural wind load data, and IGCC/NFRC glass test reports are provided directly with containerized shipping dossiers.
What acoustic glass buildup is recommended for hotels and residential projects near the Holy Mosque (Al-Haram)?
For properties situated in the Central Zone of Makkah where pedestrian and vehicular crowds produce continuous baseline sound levels of 75dB to 85dB, we advise installing asymmetric acoustic double or triple glazed assemblies. A field-proven configuration includes an exterior 8mm clear toughened pane, a 16mm argon gas cavity with warm-edge structural spacers, and an interior 12.76mm acoustic laminated glass layer (6mm + 0.76mm acoustic SoundStop PVB + 6mm). This asymmetric mass configuration eliminates critical frequency resonance, achieving a verified sound reduction index of Rw 42dB to 46dB, ensuring complete rest and acoustic comfort for guests and residents.
How does DERCHI manage shop drawings, customization, and oversized sliding openings for luxury villas?
Every order commences with comprehensive technical evaluation. Our dedicated R&D engineering department takes your architectural design parameters, structural wind pressure calculations, and rough opening dimensions to produce precise 2D CAD and 3D BIM shop drawings. For modern Saudi villas and grand majlis spaces, we specialize in heavy-load multi-panel sliding configurations (up to 3.5m height and 300kg to 500kg sash capacities) utilizing imported German or Italian concealed hardware, heavy-duty tandem stainless-steel rollers, and hidden motorized automation integration options.
What surface treatment ensures aluminium longevity against intense UV radiation in the Western Province?
Makkah receives some of the highest solar UV radiation levels globally. Standard polyester powder coatings degrade, chalk, and fade within 3-5 years. DERCHI exclusively specifies Qualicoat Class 2 / AAMA 2604 super-durable powder coatings or Class 3 fluoropolymer PVDF (polyvinylidene fluoride) liquid coatings, formulated with inorganic ceramic pigments. These finishes carry 20 to 30-year manufacturer warranties against gloss loss, micro-cracking, and chalking, maintaining their architectural richness across decades of severe solar exposure.
