Standard non-thermal aluminium profiles exhibit a high thermal conductivity rate (approx. 200 W/m·K). In Saudi Arabia, where exterior ambient temperatures exceed 50°C during summer peak and surface aluminium temperatures can hit 75°C, non-broken frames act as thermal bridges. This results in massive HVAC energy consumption, indoor cooling loss, and frame condensation during humid coastal nights in Jeddah or Dammam.
Our CE-certified thermal break aluminium windows utilize high-precision Polyamide PA66GF25 (25% Glass Fiber Reinforced) thermal insulation strips. By inserting these engineered polymer barriers between the interior and exterior extrusions, heat conduction is reduced by over 85%, achieving overall window U-values below 1.4 W/m²K.
Our thermal break profile systems are engineered to exceed SASO 2927 energy conservation standards, lowering building Cooling Loads (RT) by up to 34% and direct AC electricity demand during peak summer grid hours.

From desert heat and dust storms in Riyadh to saline coastal humidity in Jeddah and futuristic sustainable standards in NEOM.
How strict energy efficiency mandates, mega-developments, and smart home automation are driving window specification requirements across KSA.
With Saudi Arabia accelerating its National Energy Efficiency Program (SEEP), the Saudi Building Code enforces stringent U-value caps for residential and commercial fenestration. Developers can no longer install non-thermally broken profiles, escalating demand for certified PA66 thermal break factory imports.
Modern Saudi villa owners and commercial projects are moving toward motorized magnetic levitation sliding doors and electrochromic Smart Glass (PDLC). These technologies provide seamless indoor-outdoor transition, instant privacy control, and effortless operation of heavy double-glazed panels.
Saudi Arabia’s desert geography experiences seasonal Shamal sandstorms. Future-proof window systems now require continuous EPDM compression gaskets, integrated pressure equalizer drainage, and acoustic insulation to block fine particulate dust (PM2.5) and high ambient noise.
25+ years of specialized engineering, vertically integrated manufacturing, and comprehensive export logistics designed for frictionless international delivery.
Our factory systems hold full CE certification (EN 14351-1) and test documentation required for SABER system registration, ensuring hassle-free Saudi Customs clearance at Dammam, Jeddah, and King Abdullah Ports.
Our in-house facade engineering team reviews your CAD/BIM architectural drawings, calculates structural wind loads, and returns comprehensive CAD shop drawings for sightline and U-value sign-off prior to extrusion cutting.
Profiles are wrapped in protective film, fitted with heavy corner guards, and packed into steel-reinforced wooden crates. Insulated glass units ship in steel A-frame containers to guarantee zero transit damage across ocean freight lines.
Direct technical and commercial answers regarding SABER clearance, Saudi Building Code compliance, shipping lead times, and custom factory manufacturing.
Yes. Our factory provides full CE test certificates (EN 14351-1), thermal performance laboratory reports, and factory production control (FPC) audit documentation needed to register Certificate of Conformity (CoC) documents on the SABER platform for smooth Saudi Customs clearance.
We combine 24mm to 34mm PA66GF25 polyamide thermal break profiles with double or triple-glazed Low-E glass units (argon gas filled with warm-edge spacers). This build-up achieves window system U-values as low as 1.2 to 1.4 W/m²K, comfortably passing SBC energy code limits for all Saudi climatic zones.
For coastal and high-humidity areas, we specify Qualicoat Class 2 Superdurable Powder Coating (80μm thickness) or Fluorocarbon PVDF coating, supplemented by anodized surface pretreatment (15-25μm). This ensures 10+ years of resistance against salt fog corrosion, color chalking, and UV fading.
Our Saudi-spec windows feature multi-barrier EPDM compression gaskets, continuous nylon weather-stripping, and raised water-barrier sills with stainless steel drainage caps. This prevents sand accumulation and maintains air tightness (Class 4 EN 12207) during heavy Shamal dust storms.
Standard custom window orders take 4 to 6 weeks for precision manufacturing and quality inspection. Ocean freight transit to Jeddah Islamic Port or King Abdulaziz Port in Dammam typically adds 18 to 25 days, allowing total project delivery in under 60 days from drawing sign-off.
Absolutely. We specialize in custom architectural fabrication. Our CNC bending equipment accurately shapes thermal break extrusions for arched casements, Gothic windows, and floor-to-ceiling minimal sliding doors reaching panel heights up to 4.0 meters.
For direct sea freight export, our standard MOQ is one 20ft container load or one complete villa project scope. For trial projects or distributor showroom samples, consolidated LCL shipping crates can be arranged upon technical evaluation.
We supply a 10-year warranty on aluminium profile extrusions and surface coatings, a 5-year warranty on insulated glass unit seal integrity, and a 3-year warranty on European hardware. Every shipment includes spare hardware kits, installation guides, and remote engineering commissioning video support.
Send us your architectural drawings, window schedules, or BOQs. Our specialized export engineering team will provide system recommendations, U-value calculations, and factory-direct pricing within 24 hours.
