This series is a product created with a simple and fashionable style and systematic thinking.

The main frame has multiple cavities and multiple bearing points, which further improves the safety and wind pressure resistance of the whole window.

It adopts a flush design inside and outside, which can be equipped with arc chamfer, and the screen sash can be equipped with high-transparency screen mesh.

The outer frame can adopt high-energy drainage or floor drain drainage. Installing a windproof drainage hole cover can solve the whistling sound caused by hidden drainage.

The outer frame, conversion frame, and sash are all designed with glue injection corners.

The insulation strips of the outer frame and conversion frame are 35.3mm wide. The insulation strips are designed as vertical isotherms.

The glass sash adopts a three-stage sealing structure. The glass adopts a glue-free strip process (EPDM is used inside the glass, and EPDM foamed composite soft and hard co-extruded strips are used outside the glass), which greatly increases the extrusion amount of the outer glass strip.

A large bevel pressure line or a square pressure line can be selected.
