We customized and designed a full set of high-performance door and window systems for a private residence of a prince in Qatar, and exported them to meet the needs of sound insulation, heat insulation, privacy and comfort in the hot and dry climate. The project uses high-strength aluminum alloy system doors and windows from GOWELL, with multi-layer hollow Low-E glass, to effectively block ultraviolet rays, noise and heat. The multi-sealed design of doors and windows prevents the intrusion of wind and sand, keeping the interior clean. In addition, we provide personalized customization according to the architectural style and interior design of the residence to ensure the unity of beauty and function. The final result has been highly recognized by the prince. Its excellent sound insulation and heat insulation performance, privacy protection, intelligent control and overall visual effects perfectly meet the prince's needs for a high-quality living environment, demonstrating our technical strength and service level in the field of high-end doors and windows.
