Design features:

The constant high performance system adopts European standard design, profile, hardware and accessories perfectly compatible with its own system.
Medium constant pressure balance principle design and structural drainage system, smooth drainage, good water tightness; use high-grade imported hardware actuator, open flexible, zero noise, ensure ventilation rate; large fixed ground glass, wide field of vision, high lighting rate, and the window fan condition is good, not easy to damage.

Product performance:

The insulation profiles are made of European technical standard, reasonable design of profile structure, high thermal insulation and high strength, tight joints, noise and sound insulation.
