Reasons and solutions for poor sealing performance of doors and windows

3/21/2022

Doors and windows are an indispensable part of daily home life. Many people think that they only need to be installed, and they are not so particular. In fact, this is a wrong idea. The poor sealing performance of doors and windows will bring a series of problems, such as water leakage and air leakage. The following guest door and window software will introduce the reasons and solutions for the poor sealing performance of doors and windows, and we hope to help you.

01. Uneven door and window profiles

The main reason for the air leakage of doors and windows is the tightness between the door and window sash and the frame, and the flatness of the profiles is an important factor affecting the tightness. If the flatness of the profile is not enough or is deformed, there will be a certain gap between the door and window fan and the frame, resulting in air leakage.

countermeasures

Choose a good quality brand. Good doors and windows are made of high-quality profiles, and the assembly is also quite rigorous. The corners are very flat, and there are almost no gaps to prevent the leakage of rainwater and wind.

02. The quality of the sealing strip is inferior or aging

The sealing strip is the key to the sealing of doors and windows, and the quality of the sealing strips on the market varies greatly. High-quality sealing strips have strong toughness, strong wear resistance, and are not easy to break; while poor-quality sealing strips are very fragile, easy to corrode, break, and fail to achieve the sealing effect. If the sealing strip is not installed properly, unevenness or bulging occurs, which may cause air leakage.

countermeasures

The EPDM sealant strip is used, which has strong weather resistance, anti-ultraviolet radiation, and anti-aging, and still maintains good elasticity after long-term exposure.

03. There are cracks between the frame and the wall

During the installation of doors and windows, the workers did not do a good job of sealing the door frames, window frames, and walls due to rushing or cutting corners. Especially in old houses, the walls loosen during the settlement process, and the tightness between the doors and windows is reduced. If the waterproof glue is not evenly spread, the sealant is not done enough, or the expansion bolts are not nailed down, the frame and the wall will not be able to "tightly fit." It is easy to collapse in rainy weather in summer and cause air leakage in autumn and winter.

countermeasures

Install it carefully, fill the gap between the window frame and the wall with styrofoam, then cut it neatly and apply waterproof glue evenly.

04. The hardware lock is not strong

The quality of door and window hardware is also closely related to sealing performance. Especially the casement window, which relies on the drive of the hardware for sealing. If the quality of the drive is not good, the lock is not strong enough, and it is easy to leak air from the edge of the window sash.

countermeasures

High-quality hardware fittings and locks are used. Good hardware, high processing precision, durable, and the lock point is the movable rotation lock point, the friction is small, the closing is labor-saving and smooth, and the lock is U-shaped, which limits the movable dimension of the lock point, and the window sash is locked. More closely.

Tegood doors and windows are made of high-quality EPDM tape, which has very good airtightness: effective heat and sound insulation.
