Awning window Grants

TOSTEM’s GRANTS awning window features a sturdy aluminum frame combined with large glass panels, expanding views and maximizing natural light. Its flexible top-hinged design allows for easy regulation of airflow and sunlight while creating an open, modern, and pleasant atmosphere. Every detail—from the frame and hinges to the glass—is meticulously crafted for smooth, durable, and reliable long-term operation across various living spaces.

Sturdy and Refined Frame

Featuring a 120 mm frame depth for 2-track systems and 178 mm for 3-track systems, paired with a 50 mm sill height, the window balances structural strength with sleek elegance. The finely treated frame surface enhances load resistance and prevents deformation from mechanical impacts or strong winds. This detailed design elevates overall aesthetic value, adding a modern, high-end highlight to the entire building.

Versatile Glass Compatibility

The GRANTS awning window accommodates glass thicknesses up to 31.5 mm, supporting safety glass, acoustic glass, and thermal insulation glass. This flexibility enables tailored selection based on specific needs, significantly enhancing sound reduction and thermal efficiency to keep interior spaces quiet, cool, and secure for the family.

Wind Pressure and Water Tightness

Achieving a wind pressure resistance of 2000 Pa (ASTM E330) and a water tightness rating of 300 Pa (ASTM E331-00), the window protects interior spaces from driving rain and harsh weather. These features maintain a dry, comfortable indoor environment, preventing interior damage while ensuring optimal ventilation.

Airtightness and Effective Sound Insulation

Meeting the airtightness standard of 10.7 m³/h·m² (ASTM E283) and a sound insulation rating of JIS 25 dB, the GRANTS awning window blocks dust, air pollutants, and outdoor noise. This contributes to a serene, relaxing indoor atmosphere that supports better sleep and daily well-being.

An Ideal Choice for Modern Architecture

Combining sophisticated design, high durability, and stable operation, the GRANTS awning window elevates architectural value while optimizing daylight, views, and ventilation. It is an exceptional fit for villas, townhouses, and high-rise apartments, bringing together aesthetics and engineering performance to create a comfortable, luxurious living space.
