Features of UPVC doors and windows

First of all, UPVC doors and windows have good wind pressure resistance and can maintain their stability and functionality under wind pressure without causing damage or dysfunction. This allows UPVC doors and windows to maintain their functional and appearance integrity even in adverse weather conditions. Secondly, UPVC doors and windows have excellent water tightness and […]

Window frame: This is the main part of UPVC doors and windows. It uses UPVC (polyvinyl chloride) as the main raw material, combined with auxiliary materials such as stabilizers, colorants, fillers, and ultraviolet absorbers, and is extruded into molded materials. The strength and stability of the window frame are very good, and it has excellent […]

First of all, it has become one of the preferred raw materials for system doors and windows with its advantages of sealing, heat insulation, fire resistance and oxidation resistance. UPVC profiles have good sealing performance and a certain degree of elasticity, which means that they will not deform, crack or discolor during use. Secondly, UPVC […]

Material and color: The main raw material of UPVC doors and windows is polyvinyl chloride (PVC-U) resin, which has good anti-aging performance, corrosion resistance and thermal insulation. The color of high-quality UPVC profiles should be white with a hint of green, and this color is not easy to age, discolor or deform under the wind […]

Appearance and color: First, observe whether the surface of the UPVC profile is smooth and the color is uniform. High-quality UPVC profiles usually appear bluish-white or bluish-white. This color is not only beautiful, but also has good anti-aging properties. Avoid choosing profiles that are yellowish in color or have obvious color differences, as they may […]

High mechanical strength: It has good water pressure resistance, impact resistance and tensile strength, especially suitable for water supply pipelines. Hygienic and non-toxic: It adopts a green and environmentally friendly lead-free formula system, which will not damage water quality or affect human health, so it is especially suitable for drinking water pipes. Lightweight, easy to […]

Visual inspection: Observe the glossiness of doors and windows from a distance to see if there is any obvious color difference. Use a ruler to measure the dimensions of doors and windows and check for deformation. Touch the surface of the door and window at close range with your hands to check whether it is […]

Observe the surfaces of doors and windows for obvious scratches, cracks or discoloration. Check whether the corners of doors and windows are intact and whether there are any signs of impact or damage. Pay attention to check whether the sealing strips of doors and windows are intact and whether they are falling off or aging. […]

First, pay attention to the source and composition of UPVC materials. UPVC material itself is an environmentally friendly material. It is made from vinyl chloride monomer through polymerization reaction, and certain additives such as stabilizers, lubricants, etc. are added. Ensuring that materials come from reliable sources and do not contain harmful substances is the basis […]

Choose well-known brands: Well-known brands usually have better technical support and production processes, and have stricter control over production and manufacturing. Therefore, choosing well-known brands can ensure the quality of UPVC profiles to a certain extent. Pay attention to the toughness of the pipe: You can test the toughness of the pipe by sawing it […]
