How to choose good pvc windows and doors

The quality of pvc windows and doors products is fake and shoddy, and the installation is not smooth, causing quality problems of pvc windows and doors products to continue to increase. At present, counterfeit windows and doors that are randomly assembled are based on the same brand of profiles, resulting in problems such as large price differences for the same brand, high moisture content, and non-standard installation. How should consumers choose pvc windows and doors products and services?

Three Ways of Counterfeiting Experts introduced that in terms of product quality, stores mainly use three ways to counterfeit and shoddy products: First, use new types of profiles, which were originally used to make doors, windows or decorative partitions. Some agents use it to package living balconies for consumers. Due to insufficient strength, product quality problems are very easy to occur; secondly, pvc profiles that are not suitable for use will deform during use. Problems such as cracking, slag shedding and discoloration; third, the windows and doors do not need lining steel or add thin tin sheets to fake lining steel, and the assembly cannot ensure the overall quality of the windows and doors. In the installation of pvc windows and doors, there are countless problems caused by the non-standard operation of the construction team. Such problems are mainly caused by the installation personnel's carelessness during transportation, loading and unloading, and installation.

Therefore, installation workers should handle it with care during installation and do not pry, throw or drop it. When knocking on the door frame, use a plastic hammer to knock slowly. Do not knock with a hammer. Secondly, after the installation, the windows and doors are skewed and the door leaves are not in good condition. This is mainly because the installation staff did not use a line drop or ruler to check the flatness of the windows and doors, the ground or the countertop during the installation process, resulting in excessive errors. Therefore, when installing windows and doors, you must follow the installation standards. Windows and doors are not up to standard. After the windows and doors are installed, one end is high and the other is low, and the gap between the sash and the frame is uneven. Sometimes there are problems such as wide at the top and narrow at the bottom or wide at the bottom and narrow at the top.

Complications caused by free installation fees When purchasing windows and doors, consumers should not blindly pursue perfect materials and ignore the technical standards and weight of production, installation, and services. Pvc windows, insulated broken bridge aluminum profiles, insulated aluminum alloy profiles, and pure solid wood windows are all environmentally friendly and energy-saving profiles. However, the products produced by different manufacturers are very different. Consumers only choose windows and doors based on raw materials, which will cause production. The manufacturer does not invest enough in installation and service projects.

In order to better attract consumers, some manufacturers offer installation fees free of charge. In the field of windows and doors, there is a saying that "three points are made and seven points are installed." A large number of quality problems in windows and doors products are caused by installation. The installation fee is waived. This is actually a trap. If there is a problem, the manufacturer can say it is an installation problem and I can evade responsibility by taking away your installation fee. Therefore, as a consumer, not only do you not pay attention to the exemption of installation fees, but you should also specify the installation materials and installation labor costs in the contract.

Observe "face" and "color" to distinguish the quality of pvc windows and doors. The appearance color of pvc windows and doors should be bluish white. If the color is too white or gray, it indicates that the stable ingredients in the material are insufficient and will easily become brittle and yellow over time; the surface should be smooth and tidy. Flat, without welding cracks; special lining steel should be embedded in door, window frames and fan profiles. The sealing tape should be flat, without curling or slipping, and the sealing tape should be colorless and odorless. The hardware is flexible and smooth; the decorative strips, seals and other auxiliary materials of the plastic steel doors and windows should be matched with the main profile; the drainage outlet and the standard air pressure equalization hole are processed in overlapping positions to prevent the direct entry of air conditioning and dust, and the assembly is tighter Part of the drainage pipe holes of pvc windows are equipped with closed outer covers to prevent precipitation from pouring into the room from the holes; the laminated glass used in pvc windows and doors should be flat, without ripples, installed firmly, and not in direct contact with pvc profiles. There is a sealing decorative strip that fits closely into the gap. If there is a double-glass partition, there should be no dust and water vapor in the partition; there should be aluminum guide rails under the sliding window to facilitate its replacement. Generally, double-acting pulleys are better than single-acting pulleys.

The technological content of pvc windows is very different. The production and processing equipment of roadside stalls is simple, the precision and strength of windows and doors cannot be guaranteed, and the lining steel of the profile is of poor quality, or even no lining, and other parts are also very poor . It is understood that under normal circumstances, if the price of a sliding window is less than 200￥, and the price of a casement window is less than 300￥, it is likely to use fake profiles, or use shoddy and cheap hardware and lining steel. Assembling components to control costs, consumers should choose carefully.

Before consumers choose a certain brand of pvc windows and doors, they can first ask the supplier for the inspection report of the plastic steel profile raw materials and check its four key indicators, namely strength, ultra-low temperature drop weight impact test, high and low temperature test specification elastic coefficient and Does the angular compressive strength test meet the requirements?
