Just as Japanese products like cars have won the confidence of customers in India for their unmatched reliability, finish, and performance, Elegance ensures you'll experience these same benefits with every TOSTEM product. It's the assurance and pride of owning true Japanese quality for your home.
Through Elegance x TOSTEM, you benefit from products that are lean in design and cost-efficient. This stems directly from TOSTEM's excellence in design, high-volume manufacturing, and meticulous cost control – from the raw ingot to the precisely fabricated window. Discover the superior difference that Japanese innovation delivers to your living space.

The TOSTEM method of manufacturing uses dedicated machines (punch & die set) for every operation, as used in mass manufacturing, which helps in driving better process control and higher production output rates. It is also easier to exercise quality control as there is a dedicated cell for each window design.

The punch system of manufacturing followed by TOSTEM is very accurate. An anodizing finish is preferred as it has a uniform thickness of 20 microns. Powder coating is also used, but is more difficult in production, as thickness usually varies between 60-120 microns. Since manufacturing tolerances are so close – manufacturing accuracy and flatness are also very high, which makes for great ease during glazing and assembly.

The test lab in Japan is accredited by the Japanese Government. The factory in Thailand has the largest testing facility for wind pressure, air tightness, water tightness, material composition, sound isolation, thermal insulation, light & UV resistance, profile and anodizing life test against both JIS and ASTM Standards. Rollers are tested for 200,000 operations which is many times more than lifetime usage of the product.

The sash and frame are packed in separate boxes. Gaskets are supplied in roll form. The entire bundle is very compact which reduces transportation cost and transit damages. Space required for storage at the site is much less which reduces the chances of theft. Lead and lift requirements are much simplified.

Windows are intended to be opened and closed many times a day. A key aspect of the design is that effort should be minimal so that even a child can safely open the window. For instance, the effort required to open or close a 2-track / 4-panel WE Plus Door of 4200 mm width and 2400 mm height with single glass is under 50 N (5 Kgs). The effort is so less that it does not require any mechanical assistance or automation.

Aluminum is 100% recyclable and has a higher resale value as compared to other window materials. It is also environment friendly, fire-safe, and does not release toxic fumes in event of a fire. The life of aluminum windows is much longer.
The traditional method of window manufacturing, with its limited mechanization and reliance on batch production, often leads to inconsistencies. Fabrication and assembly are partly done in the factory and partly on-site, a slow process where final quality largely depends on worker skill during installation – opening many points for potential compromise in actual performance.
At TOSTEM x Elegance, we embrace the revolutionary Pre-Engineered Window (PEW) System. Much like pre-engineered buildings, our windows are meticulously designed and precisely fabricated entirely at the factory. This advanced process ensures every component is crafted to exact specifications under controlled conditions, guaranteeing unwavering quality from the outset.
Only the swift and seamless assembly of these perfectly engineered components takes place on-site, reducing reliance on manual skill and eliminating quality dilution points. The TOSTEM x Elegance PEW System guarantees superior, consistent performance

> The entire window is manufactured at the factory, except assembling and glazing.
> Logistics and storekeeping become easy as all the boxes are well labeled.
> All hardware comes pre-fitted from the factory; site work requires minimum time.
> The Pre-Engineered window comes in boxes – separate boxes for sash and frame are dispatched.
> Manufacturing accuracy is good and there is no mismatch during installation.
At Elegance Window Solutions, our partnership with TOSTEM ensures an unwavering commitment to developing and delivering products that perfectly meet our customers' requirements. This dedication is forged through TOSTEM's rigorous design and testing protocols.
Every TOSTEM design undergoes detailed inspections, meticulously assessing crucial criteria such as basic performance, long-term durability, and robust weather resistance. Only designs that successfully pass these exceptionally strict quality-control tests are approved for production and delivered to you.
Windows are thoroughly tested on all basic performance parameters such as:








Experience superior comfort with Elegance x TOSTEM's exceptional Air Tightness. Our precision-engineered windows drastically reduce air leakage, preventing dust intrusion, boosting AC efficiency, and significantly improving sound insulation. Tested for minimal air permeability (8-10.7 m³/m²/hour), our solutions ensure a cleaner, quieter, and more energy-efficient home.

During monsoons, conventional windows often fail. Elegance x TOSTEM's Water Tightness Performance prevents water infiltration and interior damage from heavy winds and rain blow-back. Our robust solutions are tested to resist significant water pressure (150-300 Pascal). Guaranteeing a watertight, protected home, even in the harshest weather.

Create a tranquil oasis with Elegance x TOSTEM's superior Sound Insulation. Our windows significantly block outside noise, ensuring a quieter home. With just a 10dB reduction halving perceived noise, TOSTEM windows with 6mm glass are tested to reduce sound by 25 Decibels. Enhance your peace further with thicker glass options.

Safeguard your home with Elegance x TOSTEM's robust Wind Load Resistance. Our windows are engineered to safely sustain intense wind pressure, preventing damage or breakage. We ensure our solutions reliably withstand significant wind loads (measured in Pascal). This guarantees unwavering stability and protection for your home, even against severe gales.
