Door and window seals are indispensable in winter

In winter, cold areas generally like to seal doors and windows, because it will be warmer. So, what aspects do you need to pay attention to in the sealing of doors and windows in winter?

1. Uneven door and window profiles

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

2. Sealing strips are indispensable

Sealing strips are the key to sealing doors and windows, and the quality of sealing strips on the market currently varies greatly.Good 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 and break, and can not achieve the sealing effect.I-ECO coated sealing strip is a good choice. It has achieved excellent results beyond all traditional products in aging resistance, fatigue resistance, compression deformation test, compression force test, heat conduction K-value test, water intrusion, water permeability and other tests; at the same time, the coated sealing strip is energy-saving and environmental protection, sound insulation and noise reduction, anti-strong ultraviolet rays, non-toxic, does not react with any paints and cleaning agents, and caters to the theme of green and healthy in the new era.

3. There are cracks between the frame and the wall

During the installation of doors and windows, many winter door and window sealing workers did not do a good job of sealing between the door frame, window frame and the wall due to haste or cutting corners.Especially in old houses, the walls are loosened during the settlement process, and the adhesion between the door and window frames is reduced.If the waterproof glue is not evenly applied, the sealant is not made enough, or the expansion bolts are not nailed firmly, it will make it impossible to “tightly fit” between the frame and the wall.It is easy to collapse glue in rainy weather in summer, and air leakage is caused in autumn and winter.

4. The hardware lock is not strong

The quality of door and window hardware is also closely related to the sealing performance.Especially casement windows, which rely on hardware actuators for sealing, if the quality of the actuators is not good, it is easy to leak air from the edge of the window sash.When the doors and windows are locked, the lock points and lock seats are firmly fastened together, and they cooperate with the hinges or sliding supports to produce a strong sealing pressure, which makes the sealing strip elastic and deformed, thereby providing sufficient sealing performance for the doors and windows.Therefore, hardware that is not firmly locked will greatly reduce the sealing performance of doors and windows.
