Ez Series

The Ez System by TOSTEM is a premium aluminum glass curtain wall line specifically designed for mid-scale and low-rise commercial projects. Featuring a minimalist, modern structure alongside rapid installation, the Ez System delivers a refined, seamless façade that is ideal for offices, showrooms, and commercial center podiums.

High Aesthetic Appeal and Long-Lasting Beauty

The Ez System utilizes a flush-glazing solution where glass is mounted flush with the outer edge of the aluminum frame, creating a completely flat, seamless curtain wall with minimal visible profiles. This design offers a sophisticated, modern look while maximizing interior views. The aluminum surface treatment uses advanced technology to maintain color durability for up to 40 years while providing exceptional scratch resistance.

Superior Weather Resistance

The Ez System meets the S-3 wind pressure resistance standard (1600 Pa) under JIS standards, far exceeding typical market offerings. Its W-5 water tightness rating (500 Pa) ensures interior spaces remain dry even during severe storms.

Effective Sound Insulation and Energy Efficiency

With sound insulation performance up to 25dB, the Ez System creates a quiet indoor environment by filtering out noise from traffic and surrounding areas. Its A-4 air tightness rating (2m³/m²/h) prevents air-conditioned air leakage, contributing to significant electricity savings and a comfortable living environment.

Optimized Performance Through Smart Structure

The Ez System integrates an internal hidden drainage system, enhancing water resistance and extending the curtain wall’s durability in harsh weather. Manufactured to Japanese standards, the aluminum frame guarantees high precision, rigidity, and strong load-bearing capacity.
