Blows from a plastic window sill why and how to remove

You go to the window to fix the curtain and suddenly you feel a cold air bubble at the top of the window.

As a private master in window repair with 20 years of experience, I often hear this question from the residents of Minsk and Minsk district.

Window design and blowout: where the crack is formed

To understand the reason, you need to look into the device of the reverse-reverse shutter. The top loop consists of two parts: one is attached to the frame, the other (the moving loop) to the shutter. When the window is closed, this moving part lies on top of the sealing contour, which runs along the perimeter of the shutter.

Where does the air come from?Drainage holesThe air from the street passes through the interior of the profile chambers and exits to the area of the upper loop where the sealing is interrupted. Under normal conditions, this microwave is invisible and does not affect the temperature in the room, especially if there is a battery running under the window.

When a lightweight carriage becomes a problem

There are several situations where a design feature becomes a real discomfort:

• I'm not going to. It's a super-powered pull.In modern high-rise air conditioning systems, a powerful traction is created that 'laquo' sucks air out of the apartment, increasing the flow through all the micro-loops. Sometimes this causes even a whistle or scream in the area of the loop.
• I'm not going to. Displacement or damage to the sealant.If the sealing rubber is moved from one corner to the other during installation or operation, the resulting gap will allow for much more air.
• I'm not going to. No radiator under the window and high humidity.Cold flow, when it hits the loop, can cause it to freeze and condensate to the rectum.
• I'm not going to. It's a personal sensitivity.Some people react sharply to the slightest movement of cold air.

If you have any of these problems, do not delay; it is better to invite a specialist for diagnosis.

3 ways to reduce or eliminate the bloating from the loop

Method 1: Temporary measure (self-imposed)

Use a thin strip of self-adhesive sealant made of sprayed polyethylene (which is sold in any household item) and apply it directly to the fixed part of the frame, in the contact area with the sealant of the shutter.

Method 2: Regulating and checking the sealant (better trust the master)

We need to check:

• ✔ What is it?Correctness of the angle of the sealant (didn 't jump out of the gap)
• ✔ What is it?Adjust the shutter press; it may be less tightly pressed in the upper corner.

I often do this.The window adjustmentin Minsk — it is a cheap service that solves the problem quickly.

Method 3: Radical solution for & quot; singing & quot; windows

If the cause is hypertension and the window is'swinging' and the temporary measures do not help, you can consider point sealing of drainage holes from the street side. Important: do not glue them completely! Use special dust/wind protection valves for drainage or close the holes carefully with silicone, leaving a small gap for water to drain.

Two-container vs. three-container windows: What to choose to avoid a dueling

Standard windows have two-contour seals (two rows of rubber: on the slit and on the frame). More expensive three-contour systems (with an additional third contour) virtually eliminate bloating through the loops, as they create a more complex maze for air.

For most condominiums with standard ventilation, no. Two-way windows (for example, from market leaders REHAU, KBE, VEKA) with quality furnishings (Roto, Maco, Siegenia) perform their functions well, easier to maintain and repair.

Why should I be the one to make the diagnosis?

• ✔ What is it? 20+ years of experience.I know all the details of the window frames and I can quickly determine the true cause of the slide.
• ✔ What is it? Free travelI'll look through the windows, give recommendations and name the exact cost of the work.
• ✔ What is it? It's a professional approach.I only use high-quality materials and original parts.
• ✔ What is it? Guarantee up to 1 yearI'm here for all the work, in writing.
• ✔ What is it? It's a dirty job.I'm cleaning up after myself.
