System Aluminum Windows

System Aluminum Windows are factory-engineered, precision-tested window solutions where every component like frames, seals, hardware, and glass is designed to work together as a complete system. Unlike conventional fabricated windows, system windows are pre-tested for wind pressure, air infiltration, and water resistance, ensuring consistent performance and longer life.

Regular aluminum windows are assembled on-site using basic profiles, often without performance testing. System aluminum windows are factory-engineered with precision-fitted components, certified under global standards for air, water, and structural performance. They offer better insulation, tighter seals, smoother operation, and significantly longer durability.

Aluminum window frames have a very long lifespan — you can expect them to last between 40–60 years if installed correctly. TOSTEM system aluminum windows are built to international standards and engineered to withstand India’s extreme weather conditions, including monsoons, coastal humidity, and intense heat.

Yes. Aluminum windows are capable of withstanding extreme climatic conditions such as rain, wind, dust, and heat. They are also designed to be UV and termite-resistant, maintaining a clean and hygienic environment that requires minimal maintenance. This makes them ideal across India’s diverse climates from coastal cities to hot and dry interiors.

Modern system aluminum windows with thermal break technology significantly reduce heat transfer between indoor and outdoor spaces. When paired with double or triple glazing and low-E glass, they can be highly efficient. This helps reduce air-conditioning costs in Indian homes.

Aluminum windows require minimal maintenance. Regular cleaning and occasional lubrication of moving parts are typically all that’s needed to keep them in top condition. A mild detergent and water solution with a soft cloth is all that’s required for cleaning. They do not need repainting, polishing, or chemical treatments.

Yes. Aluminum is 100% recyclable without losing quality, making it a great choice for environmentally conscious homeowners. It also does not release toxic fumes in the event of fire, making it a safe and sustainable choice for modern homes.

System aluminum windows are available in multiple configurations including sliding windows, casement windows, tilt-and-turn windows, fixed windows, and minimal frame systems. TOSTEM offers series like GRANTS, ATIS, We Plus, and We 70, each designed for different architectural styles and performance needs.

Yes. Aluminum frames are available in any RAL color through a process called powder coating. You can also choose dual colors — a different shade on the outside versus the inside — allowing you to match the frame perfectly with your property and décor.

The price per sq. ft. varies depending on the type, features, and level of customization. Factors include frame series, glass type (single, double, or triple glazed), thermal insulation, and hardware. TOSTEM offers transparent, value-driven pricing across its product range.
