The natural desire of any customer is to purchase high quality plastic windows that will serve for a long time. Therefore, you should buy profiles only from professional companies with excellent recommendations and many years of experience.
Necessary
- - Quality certificate;
- - GOST standards;
- - Licensing permission for the company's activities;
Instructions
Step 1
The quality of plastic windows depends on the materials used in the production, the availability of modern technical equipment and the seller's practical experience in installing profiles. Therefore, do not forget to demand a quality certificate when purchasing windows. Make a purchase only if the company provides a service for further maintenance of its products.
Step 2
Preliminarily, familiarize yourself with GOSTs on the quality of profiles adopted in Russia. If plastic windows meet European standards, give preference to products that comply with RAL-GZ 716/1. These requirements are considered the most stringent in relation to the physical and mechanical parameters of a plastic window, as well as fittings and components.
Step 3
You can be convinced of the professional qualities of the company by asking the manager to provide a license for the activities of the company, which mentions the compliance of the quality of services with accepted standards. Prefer companies that not only sell profiles, but also install them. If you contact different companies to buy and install a profile, you can then look for someone to blame for a long time when the plastic window breaks down.
Step 4
Inspect all profiles before installing systems. Pay attention to the absence of mechanical damage, surface deformation both on the system and on the double-glazed windows. Quality windows have clear contours. The presence of chips, breaks in lines, violation of the general color scheme are warning signs. Be sure to check the presence of all the accessories: window sills, ebbs, fittings.
Step 5
During the installation of the window system, check the quality of work. For example, an excessive amount of polyurethane foam introduced in violation of the instructions will subsequently lead to deformation of the profile. Window sills and sills can be installed after checking for deformation as a result of mounting the system. Check the functionality of all installed fittings, ask for adjustments if necessary.
