🌟 Why Choose TOSTEM French Windows/Doors (ATIS)
✅ 1. Timeless Aesthetics & Design
French windows and doors bring classic elegance and architectural beauty to any space.
Large glass panels and slim aluminium frames create expansive, unobstructed views and flood interiors with natural light — visually enlarging rooms and enhancing ambiance.
✅ 2. Superior Build Quality with Japanese Technology
TOSTEM products are engineered using advanced Japanese technology for precision, strength, and performance.
The aluminium frames are corrosion-resistant, durable, and designed to withstand tough weather — heat, humidity, or rain — making them suitable for varied climates like India’s.
✅ 3. Excellent Performance & Comfort
Energy efficiency: Tight seals and quality gaskets help reduce heat transfer, improving indoor comfort and potentially lowering energy bills.
Weather & air tightness: Robust sealing systems minimise air leakage and water penetration, keeping interiors dry and comfortable.
Noise reduction: Rubber gaskets and solid construction help insulate against outside noise for quieter indoor spaces.
✅ 4. Easy Maintenance & Longevity
Aluminium frames require minimal maintenance — no warping, rusting, or termite issues like wooden alternatives.
TOSTEM’s TEXGUARD coating (on many products) protects against UV, weathering, and fading for years.
✅ 5. Smooth Operation & Practical Use
Well-engineered hinges, handles, and hardware offer effortless opening/closing and reliable daily use.
French doors open fully, improving ventilation and accessibility (easier to move furniture or walk through compared to partial-opening systems).
✅ 6. Customisation & Versatility
Available in multiple styles, colours, and configurations to suit your home design — inward or outward swing, various finishes, and sizes.
✅ 7. Robust Security
Multi-point locking and strong frames add security without compromising design.
✅ 8. Installation & Support
TOSTEM products are factory-prepared (like “window-in-a-box” for easy fitting), making installation more straightforward and consistent.
