Engineered to Outperform

Every TOSTEM window undergoes rigorous testing across four critical performance parameters. Only designs that pass strict quality-control tests make it to your home.

Wind Pressure Resistance

TOSTEM windows sustain wind loads up to 2000 Pascal enough to resist winds that would collapse wooden structures.Tested per JIS A 1515. At 2000 Pa (≈216 km/h), steel towers may fall. Your windows won't flex.

Water Tightness

Advanced drainage design with one-way valves prevents water ingress even during Pune's heaviest monsoon downpours.EPDM rubber gaskets + nano-tech corner seals. Zero silicon dependency. Tested per JIS A 1517.

Sound Insulation

Reduce external noise by 25 decibels with standard 6mm glass — effectively halving perceived sound levels. Rubber gaskets replace wool-pile for superior acoustic sealing. Higher reduction with laminated glass options.

Air Tightness

Precision-sealed profiles block dust infiltration and improve AC efficiency by preventing air leakage.Permissible leak: 8-10.7 m³/m²/hr. Tested per JIS A 1516. Improves HVAC efficiency by up to 30%.

Tostem Texguard Anodizing

Benefits Of Textguard Coating

Colour Retention – TEXGUARD protects the aluminium against harsh environmental conditions, making the colour gloss stay for at least 40 years.

Increased Hardness – Dense coating of TEXGUARD improves hardness and provides scratch resistance for the aluminium surface. 

Ease of Cleaning – Dust and dirt accumulation resistance quality of TEXGUARD makes the task of cleaning the surface effortless. 

The Journey of a Millimeter

 Every TOSTEM window follows a precision manufacturing process that eliminates human error and ensures test performance equals actual performance.
