[0054] S2: Determine the position and quantity of the insulation panels below the windows, and make a detailed groove design for the insulation panels below the windows.

[0055] The insulation board used for installation under the window adopts a special insulation board 3. A groove 7 is designed on the top surface of the special insulation board 3 close to the wall. The groove 7 is a strip-shaped through groove. The bottom surface of the groove 7 is designed with a certain slope. The bottom surface of the groove 7 is inclined toward the two sides of the window sill in the longitudinal direction and inclined toward the direction away from the window sill in the transverse direction, that is, inclined toward the special insulation board 3.

[0056] In this embodiment, the slope of the bottom surface of the groove 7 is 0.03%.

[0057] In the present embodiment, the special thermal insulation board 3 can be a complete board body or can be composed by splicing multiple special thermal insulation board units 8.

[0065] By using the above method, the rainwater under the window sill enters the groove 7 on the special thermal insulation board 3 and is drained through the slope inclined to both sides of the window sill, avoiding the rainwater from penetrating into the room from the weak position such as the window.

[0066] S6: after the installation of the special thermal insulation board 3 is completed, water filling test is performed to observe whether water accumulation occurs at the lower opening of the window sill. If water accumulation occurs, the bottom surface of the groove 7 is again sloped, and after the slope finding is completed, waterproof treatment is performed. If no water accumulation occurs, no treatment is performed.

[0067] Similarly, the slope finding is performed by anti-cracking mortar, and the waterproof treatment is performed by brushing waterproof material.
