The balcony at home is sealed with double layer glass colored aluminum, no seal and air leakage, how

1. Air leakage in the upper and lower slide passages of the sliding window and air leakage in the frame gaps.

Due to its beautiful appearance, large opening area and no space, the sliding window is currently the most widely used opening method, but it is also the window that is most likely to leak air. The solution to this type of window leakage is a two-step process:

1. Remove the window sash and repair or replace the pulley, because the deformation and breakage of the pulley directly affect the pushing and pulling activities of the window sash, and will also cause air leakage.

2. Install the wool strip at the edge of the wrong pressure frame of the movable fan, the wool strip that comes with the original window will be dehaired due to wear and tear for a long time, and lose the windproof function, therefore, before the arrival of winter every year, checking and replacing the wool strip is an important measure for wind protection and heat preservation.

Second, the casement window is deformed and leaked.

The casement window is sealed by the EPDM strip extrusion at the inner mouth of the frame, and the sealing effect of the casement window itself is much better than that of the sliding window, but based on the thermal expansion and contraction and the wear of hardware accessories, there will also be air leakage caused by the falling of the window sash.

If the screw of the sash is loose, re-tighten the screw, if the corner is extruded, I am afraid that you have to go to the door and window factory to replace the corner code and re-assemble the corner. If the window sash leaks due to the wear of hardware accessories, it is necessary to tighten the hinge, adjust the position of the lock point, and replace the EPDM rubber strip.

Landlord: It's more troublesome to reinstall the seal, you can fill it with a neutral sealant.

Upstairs is right, it's better to fill with neutral sealant.
