If installed incorrectly, even the highest quality and most expensive window will lose all its advantages. It is recommended to order the installation of PVC windows according to GOST in the company in which the designs were bought.
This will make it possible to coordinate the time, and the installer will better understand all the features and nuances of fixing a certain window structure. GOST 30971-2002 was developed to protect the rights of customers and ensure the right level of quality of services for the installation of structures with translucent elements that are provided by window companies and companies.
In this article we will consider what you need to pay attention to when installing PVC windows in accordance with GOST.
1. Three-seam mounting seam
Installation of metal-plastic constructions is a responsible process that requires a serious approach to the issue of thorough protection from all external influences. The air temperature in any room is significantly different from the temperature in the street. And in order to prevent the formation of drafts and condensation, the installation layer is applied in three layers.
The main or middle layer is a one-component foam that provides sound insulation and thermal insulation. When installing PVC windows in accordance with GOST, it is recommended to use foam with a lower rate of secondary expansion. This will eliminate the subsequent deformation of the window structure.
Outer layer. A special
sealing tape is pre- compressed and glued to the outside of the frame immediately before installation. This tape, expanding, fills all kinds of roughnesses and irregularities, and also additionally protects against moisture and removes steam from the installation joint. To protect the bottom layer from moisture, GOST for the installation of PVC windows involves gluing on the profile and the opening of a special vapor-permeable (diffusion) tape.
The inner layer protects the mounting foam from moisture forming inside the room. This layer consists of several self-adhesive tapes that have vapor barrier properties.
2. Quality insulation materials
It is recommended that, following the GOST criteria, the installation of PVC windows is made of high quality materials.
3. Window installation technology in the opening
It should be remembered that the installation of PVC windows according to GOST does not allow the use of only one mounting foam.
The fasteners must be selected based on the weight and area of the window structure, taking into account the strength of the bearing walls and the level of permissible loads. Anchor plates are inserted into special grooves . Anchors in the window opening are fixed with dowels.
The technology of installing plastic windows in accordance with GOST is a difficult process that requires an employee of high professional qualifications and in-depth knowledge. The warranty on the installation can only be given by professionals.
Installing PVC windows according to GOST is a painstaking process, but the benefits of observing it are worth it. This provides enhanced and multi-level protection of the joint from moisture and additional tightness, reliability of installation work and comfortable operation of the product.
