The technical scheme that the utility model solves its technical problem adopts is:

The provided anti-seepage structure of the window includes the external wall insulation board, the first mesh cloth, the second mesh cloth, the outer mortar layer, the inner mortar layer, the window insulation board, polyurethane waterproof coating, window frame profiles, polyurethane Styrofoam and the wall, the outer wall insulation board and the window insulation board are respectively connected to the wall through the mortar layer, the first mesh cloth and the second mesh cloth are wrapped in The external wall thermal insulation board and the window thermal insulation board are layered and coexist in the mortar layer, the window thermal insulation board and the window frame profile are sealed by the polyurethane waterproof coating, and the window frame profile and the window frame profile are sealed The walls are sealed by the polyurethane foam glue.

The second mesh cloth on the window insulation board needs to be turned over, that is, the second mesh cloth needs to be continuously spread to the bottom of the window insulation board.

Compared with the prior art, the utility model has the advantages of avoiding the occurrence of water seepage while ensuring the sealing effect, thereby protecting the interior decoration and ensuring living comfort, easy construction, low cost and good durability , suitable for energy-saving renovation of existing buildings.
