Experience windows that stand the test of time with uPVC windows renowned for their durability. Crafted from resilient unplasticized Polyvinyl Chloride, these windows are resistant to rot, corrosion, and fading. Unlike traditional materials, uPVC windows maintain their structural integrity, ensuring a long-lasting investment that requires minimal maintenance over the years.
Compared with traditional windows, the cost of UPVC windows is lower than that of aluminum alloy windows. UPVC windows with the same use efficiency can save 30%-60% of the cost compared with aluminum alloys. This is the main reason why UPVC windows are popular. UPVC windows have strong flexibility. In the molten state, plastic has high fluidity, so it can form a precise cross-sectional structure through the mold, so as to meet the functional requirements of the window. In addition, a compartment can be formed to improve the thermal insulation, sound insulation, and drainage functions of the windows, and avoid corrosion of steel bars. The energy-saving plastic windows of UPVC windows have superior technical characteristics than other windows in terms of energy saving and improvement of indoor thermal environment.
Prioritize the safety of your loved ones and belongings with uPVC windows that offer enhanced security features. Equipped with robust locking mechanisms and sturdy frames, these windows provide reliable protection against potential intruders. The inherent strength of uPVC material adds an extra layer of defense, allowing you to rest easy knowing your space is secure.
Make an eco-conscious choice with uPVC windows that align with sustainable values. These windows enhance energy efficiency, reducing your carbon footprint and contributing to a greener lifestyle. By minimizing energy consumption, uPVC windows not only lower your utility bills but also help protect the environment for future generations.
UPVC windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., are extruded to form the material, and then cut, welded or screwed production.
UPVC windows are a new generation of window materials, which have the advantages of high wind pressure resistance, good air and water tightness, small air and rain penetration, low heat transfer coefficient, heat preservation and energy saving, sound insulation, and resistance to aging.
In addition to the problem of filling materials, you must pay attention to the size design when installing. The size of the upvc window should be smaller than the size of the hole. At the same time, the size of the window components and the size of the drain hole of the window must be taken into consideration.
