Established in 2013 with a registered capital of RMB 20 million, Nanjing Spencer Window Co., Ltd. has emerged as a global leader in high-performance aluminum and UPVC systems. Our modern production base covers 10,000 square meters, integrating R&D, manufacturing, and international supply chains.
With an annual production capacity of 100,000 square meters, we specialize in delivering tailored solutions for residential skyscrapers, commercial hubs, and industrial facilities. In Sri Lanka, our products are increasingly favored for their ability to withstand tropical humidity and coastal salt-air corrosion while providing superior ventilation.
Sri Lanka’s climate, characterized by high temperatures and monsoon rains, demands windows that offer maximum ventilation without compromising waterproofing. Hopper windows, which hinge at the bottom and open inward at the top, are the ideal solution for high-level wall placement, allowing hot air to escape while preventing rain ingress during light showers.
In densely populated areas like Colombo 03 and Colombo 07, space is a luxury. Hopper windows are frequently used in basements, bathrooms, and small apartment units because they don't swing outward into walkways or balconies. Their design also offers enhanced security, as the opening is often too narrow for unauthorized entry, making them a top choice for commercial ground-floor applications in Sri Lanka.
The rise of luxury condominiums and the Port City Colombo project has driven demand for high-performance glazing. Our hopper windows feature thermal break aluminum technology, which is essential for reducing air conditioning loads in Sri Lanka’s luxury real estate sector, significantly lowering energy costs for homeowners and facility managers.
Spencer places strong emphasis on technological innovation and precision manufacturing. Equipped with advanced production lines and supported by an experienced technical team, Spencer maintains strict quality control throughout every stage of production.
From raw material selection to final assembly, each step is managed for high standards in durability and safety.
Optimized for energy efficiency, reducing heat transfer in Sri Lanka's intense sun.
Multi-layered laminated glass ensures a quiet interior even in busy urban Sri Lankan districts.
Sleek, modern profiles available in various finishes to match high-end architectural designs.
Nanjing Spencer Window Co., Ltd. follows the philosophy of “Quality First, Customer Foremost, Integrity-Based.” We provide comprehensive services covering consultation, customized design, and after-sales support. By integrating innovation with craftsmanship, Spencer strives to create comfortable, energy-efficient, and aesthetically refined living spaces.
Our vision is to become a trusted global partner in the door and window industry while delivering lasting value to our customers in Sri Lanka and beyond.
As the construction industry in Sri Lanka moves towards sustainable and "green" building practices, selecting the right window supplier is crucial. Hopper windows are a staple in modern architectural design due to their unobtrusive footprint and efficient air circulation. At Spencer Window, we understand the specific nuances of the Sri Lankan market—from the humid breezes of the Southern Coast to the cool, misty environments of Nuwara Eliya.
Our aluminum systems are treated with high-grade powder coatings or anodized finishes to prevent the oxidation commonly seen in coastal Sri Lankan buildings. Furthermore, our double-insulated glass helps in maintaining indoor temperatures, reducing the strain on HVAC systems in Colombo's commercial towers.
For developers looking for bulk supply or customized configurations, we offer direct factory pricing and technical support. We ensure that every unit meets international standards like CE and AS2047, providing peace of mind for structural engineers and architects working on landmark projects in Sri Lanka.
