Correct installation of windows in the house

When installing windows, it is important that the size of the window matches the opening in the wall. Correct fit and sealing of the window structure is also important..

Do-it-yourself window installation: preparation, sash removal, frame installation in the opening

The correct installation of windows in the house affects their functioning during operation. Failure to comply with the installation requirements contributes to the appearance of damage, which leads to the penetration of air and moisture into the premises, which leads to a decrease in thermal insulation.

The first step in installation is to select a window to match the size of the opening in the wall. It should be smaller than the opening, both in width and height. The opening in the wall is technically called the jamb, and the gap between it and the window frame is the mounting gap. Before installation, you must thoroughly clean the surface from dust, remove the old material containing gaskets. Ignoring the preparatory stage, the installation of plastic windows will be considered incorrect, and therefore of poor quality.

The next stage in the installation of PVC structures is to remove the sash and insert the frame into the opening. This requires both spacers and wedges. The frame must be mounted on blocks, correctly aligned in a vertical position. It is worth remembering to keep the same distance in the mounting gap at the top and side edges. At the bottom, the gap should be slightly larger due to the window sill.

Selection of fasteners

Correct installation of plastic windows with your own hands requires the selection of appropriate fasteners. When installing a window structure into an insulating layer, special window anchors are used, with which the window is attached to the wall. When installing into a wooden wall, self-tapping screws are most often used. When using dowels, the window frame is often drilled, which does not harm its properties. When installing metal-plastic window structures, employees must remember that they are affected by different loads, therefore they must be installed in such a way that the loads are transferred into the building, and not vice versa..

Installation of sealing materials

In the next step, the window structure must be supplemented with a sealing material that will be placed between the frame space and the wall. This seal must be permanent and water and air tight. The most common material used for sealing is polyurethane foam. Since it increases in volume during curing, it should be borne in mind that the frame profile may deform. This will subsequently lead to air leakage from the room. After the polyurethane foam has hardened with a sharp tool, cut off its excess to align with the edge of the frame itself.

The contact of the window with the outer wall is a very important point. Improper installation will lead to heat loss as well as moisture ingress into the room. The window structure should be carefully insulated to be sure that these negative phenomena are completely excluded. Many people decide to purchase energy efficient products that offset the rising costs of space heating. Installation of all types of window structures (including balcony or attic) is usually completed by plastering the joint between the window and the wall, both inside and outside the building..

Installing a warm window: features

A common method is warm mounting. For this, additional materials are used to increase the insulation of the window. Warm installation is effective when vapor barrier tapes or sealing films and tapes are used. The surfaces of the opening must be polished and smooth for the application of an insulating film.

Installation of PVC windows: what to look for

Beware of the following errors during installation:

  • Cleaning. By neglecting this step, gaps are formed through which air and moisture enter the room..
  • Saving on dowels. Leads to structural deformation and drafts.
  • Installation work without wedges. Plaster may crack.
  • Using incomplete waterproofing. The wall may be damp and water may drain directly into the room.

The installation of plastic windows in the house requires caution and compulsory adherence to technology. Even the best windows from well-known companies, if installed incorrectly, will eventually lose their properties and cease to provide heat to the room..
