Fixed windows are windows that are usually made of glass directly inlaid on the window frame or the window sash is fixed on the window frame and cannot be opened. They are only used for lighting and viewing. They are usually used for lighting windows in corridors, stairwells and certain parts of general windows.

The main body of the heat-insulating aluminum alloy is made of aluminum, and a plastic profile cavity is used as the heat-insulating material in the middle of the profile. This innovative structural design takes into account the advantages of plastic and aluminum alloy materials, while meeting various requirements for decorative effect, strength and aging resistance of doors and windows. The thermally insulated broken bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of air and water, and significantly improve the water and air tightness of doors and windows. The air tightness of insulated aluminum doors and windows is better than that of any aluminum or plastic windows. It can ensure that indoor window sills and floors in areas with strong wind and sand are dust-free; it can ensure that residents 50 meters on both sides of the highway are not disturbed by noise; and the thermal conductivity is better than Non-insulated aluminum alloy doors and windows reduce the cost by 40 to 70%.

High quality aluminum commercial window price will work hard on the sound insulation performance of windows .

When you purchase upvc profile double hung  window 002-2, you purchase directly from the factory.

VC sliding window is a modern, space-efficient window system widely used in residential and commercial buildings. Manufactured from polyvinyl chloride (PVC), this type of window combines durability, energy efficiency, and aesthetic appeal. The sliding mechanism operates horizontally along a track, making it ideal for areas with limited interior or exterior space where traditional casement windows might be obstructed. PVC sliding windows are known for their low maintenance requirements, excellent insulation properties, and resistance to moisture, termites, and corrosion. The multi-chambered profile enhances thermal and sound insulation, making them suitable for all climates. The double-glazed glass option further improves energy performance by reducing heat transfer and outside noise. Xiamen KDSBuilding’s PVC sliding windows are crafted with high-precision corner welding, reinforced steel inside frames, and optional security locking systems for added strength and safety. These windows are available in various configurations, including two-track, three-track, and even multi-panel designs, offering design flexibility for large openings and panoramic views. Easy to operate and clean, PVC sliding windows are a practical and stylish solution for modern architecture. Their sleek appearance, coupled with superior performance, makes them a long-lasting and cost-effective choice for any property.

Aluminum alloy window is made of aluminum alloy building profiles frame, fan structure window, divided into ordinary aluminum alloy doors and Windows and broken bridge aluminum alloy doors and Windows. Aluminum alloy Windows have beautiful appearance, sealing, high strength, widely used in the field of construction engineering, in home decoration, commonly used aluminum alloy doors and Windows package balcony. The surface of the aluminum alloy is polished and shiny by oxidation. The window sash frame is large and can be inlaid with a large area of glass, which makes the indoor light full and bright, enhances the contrast between the virtual and real facade between the indoor and outdoor, and makes the living room more rich. The aluminum alloy itself is easy to extrude, the cross-section size of the profile is accurate, and the processing accuracy is high, so many owners choose to use aluminum doors and Windows in the decoration.

Rubber strip has been used in recent years, EPDM, which can ensure better elasticity and anti-aging performance, but the glass groove rainwater with rubber strip will still leak into it, so we need to milling drainage holes and slots.
