Product Description

Product Features
At present, there are various types and styles of doors and windows, but sliding windows are still favored by many families for their advantages such as flexible opening, good ventilation and unobstructed views. Our sliding system windows are easy to open, do not take up space, and have ideal ventilation and lighting effects, which can easily meet the needs of modern living.
Structured Drainage System

Designed on the principle of isobaric pressure, it is more conducive to the rapid drainage of rainwater, preventing rainwater from accumulating in the tracks and causing internal flooding or seepage, and further enhancing the waterproof performance of doors and Windows.

Premium Hardware Accessories

High-quality premium hardware accessories are carefully selected. They are easy and flexible to open, beautiful and comfortable, and durable.

Frame-Wrapped Sash Design

The new frame-wrapped sash design perfectly integrates the glass sash into the frame, making the air tightness, water tightness and sound insulation of the entire window better, and facilitating installation.

Extremely Narrow Appearance

The appearance is extremely narrow, with the visible surface of the sash being only 33mm. This ensures the stability of the window sash while also providing sufficient light and a wide field of vision. It can also be made into a large sash to maximize the viewing field of vision.

Double-Row Wheels & Stainless Rail

The wheels feature a double-row design, which is quieter and more load-bearing. The slide rails are made of high-quality 304 stainless steel, which is more wear-resistant and less prone to deformation, ensuring balanced force distribution without shaking.

Multi-Layer Silicon Wool Strip

The wool strips that have undergone silicification treatment have better water resistance, anti-aging property and anti-wear ability. Meanwhile, the multi-layer structure design enhances the sealing performance of the window sash, which can better resist the invasion of wind and rain and also prevent the entry of flying mosquitoes, insects and ants, ensuring the safety of your home.

Double-Layer Insulating Glass

It is equipped with double-layer insulating tempered glass as standard, which not only has better light transmission but also superior performance in all aspects. With the characteristics of wide vision, high lighting and high transparency, it perfectly combines the aesthetics of space with the needs of home decoration.

Primary Aluminum Profiles

It adopts high-quality primary aluminum profiles, which have excellent corrosion resistance and load-bearing capacity, and can extend the service life of the entire window.

A sliding window, with its opening and closing, interweaves the beauty of the natural scenery outside with the warmth and vitality of the interior, infusing the home with a unique sense of warmth and beauty.

Frequently Asked Questions
Q: What is the advantage of the isobaric drainage system?

The structured drainage system is designed based on the principle of isobaric pressure, which accelerates rainwater drainage and prevents water accumulation in the tracks. This reduces the risk of indoor seepage and flooding.

Q: How narrow is the frame design, and how does it benefit the view?

The visible surface of the window sash is extremely narrow at only 33mm. This minimal profile maximizes natural light entry and offers a wider, unobstructed view while maintaining structural stability.

Q: What materials are used for the slide rails and wheels?

The sliding windows feature a double-row wheel design for smoother operation and higher load capacity. The slide rails are made of high-quality 304 stainless steel, ensuring durability, wear resistance, and shake-free sliding.

Q: How does the window protect against insects and weather?

It utilizes a multi-layer silicified silicon wool strip design and EPDM sealing rubber strips. This combination offers excellent weather resistance, prevents water and wind penetration, and blocks mosquitoes, insects, and ants.

Q: What are the standard glass and profile specifications?

The standard configuration is a double-layer insulating tempered glass of 5mm+20A+5mm. It is paired with high-quality primary aluminum profiles featuring a wall thickness of 1.8mm (external frame) and 2.0mm (internal sash).
