Project Reference: Gebze Villa Polyurethane Exterior Façade

Rigid polyurethane architectural elements used in the Gebze Villa project are manufactured with a closed-cell structural formulation. The core material features a nominal density range of 150 to 150-220 kg/m³ (țintă ~160 kg/m³), with a standardized production target of approximately 150-220 kg/m³ (țintă ~160 kg/m³). This density profile ensures high resistance against physical impacts while remaining light enough to prevent excess dead load on the building structure.

Thermal stability tests confirm operational performance within ambient temperature limits ranging from -100 °C / +80 °C. Furthermore, the material exhibits a water absorption rate sub 1%, making the profiles completely impermeable to moisture, rain, and frost cycles commonly encountered across diverse European climate zones. Dimensional stability during long-distance freight transit remains intact due to this non-hygroscopic cellular structure.

The exterior design of the Gebze Villa incorporates decorative cornices, window jamb profiles, and ornamental pilasters. A critical engineering rule applied during the design phase specifies that decorative polyurethane columns carry zero structural load. Polyurethane column covers and capitals serve strictly as non-load-bearing architectural cladding and must never replace load-supporting structural posts.

To simplify site operations, manufactured profiles by Polure were delivered with a factory-applied primer. This pre-treatment standardizes surface energy across all decorative elements, facilitating consistent paint adhesion across multi-story exterior wall surfaces.

Installation on the Gebze Villa facade required thorough substrate preparation. The wall surface must be completely dry, structurally sound, and clean from dust, oils, or loose plaster. Substrate irregularities exceeding standard alignment tolerances must be corrected prior to profile placement to avoid mechanical stress along the bonding line.

All profile corner connections and linear joint transitions were cut using sharp mechanical saws set to a precise 45-degree miter cut. Accurate miter joinery ensures tight seam alignment, reducing thermal movement stresses across profile joints in regions subject to significant seasonal temperature shifts.

Securing decorative polyurethane components to the building envelope requires a dual-fixation strategy combining chemical bonding and mechanical anchoring. Chemical bonding must be performed using dedicated polyurethane (PU) assembly adhesives. Standard silicone products are strictly prohibited, as silicone lacks the cohesive tensile strength required for permanent exterior architectural attachment.

Simultaneously, mechanical fixing using stainless steel screws is mandatory. Fasteners are driven through the profile core into the solid substrate behind it. This dual-fixing method guarantees resistance against wind uplift forces while allowing the polyurethane adhesive to cure fully under stable contact pressure.

Although factory-primed profiles provide a baseline protective layer, applying an additional secondary primer after installation remains optional depending on job site environmental exposure. Once mechanical screws are set and countersunk, screw head locations and joint seams are sealed using exterior-grade polyurethane filler. After full curing, these patched areas are sanded smooth using granulație 180-220 sandpaper to create a uniform, seamless surface topology.

Because uncoated polyurethane degrades under prolonged direct solar exposure, applying protective topcoats is mandatory. The final installation step requires applying a minimum of 2 coats of high-grade, UV-resistant exterior paint. This coating system shields the material against ultraviolet radiation, chalking, and thermal surface oxidation.

Supplying decorative profiles for international construction projects demands packaging capable of enduring long-distance freight handling. Decorative components for projects like the Gebze Villa are packed in reinforced, multi-layer corrugated boxes reinforced with edge protection to prevent impact damage during transit across European transport routes.

Polure specifies packaging and palletizing routines that accommodate variations in freight humidity and temperature. Stackable, rigid packaging prevents structural warping before installation, ensuring that architectural components arrive on site matching exact factory dimensions.
