Draft from the window: how to find a gap and insulate it for winter.

If there is a draft from the plastic window — how to find and eliminate the problem

According to ТСН: There are several typical places where drafts can occur:

• the glass unit holder,

• the rubber seal,

• window hardware, for example, from under the hinges or handle,

• the perimeter of the window frame — the joints of the slopes, windowsill, and walls.

How to determine the source of drafts in a plastic window

• By touch — run your palm along the surface of the window unit.

• With a lighter — the flame of the lighter is sensitive to drafts and can detect even a weak draft.

• With a sheet of paper — if the sheet easily pulls out due to insufficient pressure from the seal, it indicates a draft.

Insulation of window openings for winter

• Foam. It expands, filling all gaps in the perimeter of the window opening, preventing air from passing through. However, the foam must be protected from ultraviolet light.

• Mineral wool. It is an excellent insulation material for insulating windowsills and internal slopes.

• Foam or polystyrene. They are used for insulating the slopes of plastic windows.

• Silicone sealant. A reliable means to eliminate drafts between plastic parts of the window.

• Dry mixes for processing slopes, which are used for insulating the window from the outside.

• Construction tape. It is used to seal gaps, but ordinary painter's or window tape is not recommended, as it leaves marks on plastic.

Insulating the window block

• sealant,

• construction tape,

• sealant,

• thermal saving film for windows,

• mechanical insulation methods, for example, adjusting the hardware.

How to insulate plastic windows from the outside

External insulation of windows is performed in several stages:

Insulating the slopes of plastic windows

Firstly, the slopes need to be insulated. Without this, the cold will still penetrate into the room. External insulation helps to shift the dew point, preventing moisture formation. To insulate the slopes, it is necessary to:

• Prepare rigid insulation.

• Clean the slopes of dirt.

• Prime the surfaces.

• Install insulation with adhesive or special adhesive foam.

• Seal all gaps with glue.

• Install perforated corners.

• Mount a polymer net.

• Finish with plaster.

Insulating the window sills of plastic windows

To insulate the window sills, it is necessary to fill the gaps with foam or place insulation material in them. To prevent moisture penetration, a metal strip of the window sill is installed on top.

Insulating the internal slopes of plastic windows

• Treating gaps and removing old foam.

• Applying primer.

• Sealing gaps with mounting foam.

• Removing excess foam after drying.

• Installing insulation materials, such as foam or mineral wool.

• Installing drywall.

• Finishing the drywall with putty and paint.

Internal slopes are less susceptible to external factors, however, they require more aesthetic attention.

Insulating the windowsill of plastic windows

• Before insulating the windowsill, it is necessary to determine where the draft is coming from.

• Drafts between plastic parts of the window and the windowsill — sealant is suitable here.

• Heat losses between the windowsill and the wall — this requires insulation before installing the windowsill by laying insulation material.

Replacing the seal in plastic windows

To eliminate drafts from plastic windows, the rubber seal can be replaced. This is easy to do: just pull out the old seal and insert the new one.

Insulating plastic windows is an important step in preparing for the cold. The right choice of materials and their professional installation will help preserve warmth in your home and significantly reduce heating costs. There is no need to delay this process, as effective insulation can noticeably increase comfort during the winter period.
