1. Mark the corresponding position on the installed door frame opening with a line, and indicate the size. It should be noted that the height inside the frame should be higher than the height of the door leaf. The thermal insulation roller shutter door installed on the outside of the door can usually increase the K value of the door by at least 45%, and ensure that the distance between the roller shutter panel and the door frame is ≥ 40mm during installation.

2、為了將保溫卷簾門(mén)的門(mén)框固定，要先拆掉門(mén)框下部的固定板，在洞口兩側的地面要事先預留凹槽，然后進(jìn)行校正，待合格后固定木楔，將門(mén)框鐵腳與預埋鐵板件焊牢。

2. In order to fix the door frame of the thermal insulation rolling shutter door, the fixing plate at the bottom of the door frame should be removed first. Grooves should be reserved on the ground on both sides of the hole in advance, and then calibrated. After passing the calibration, the wooden wedge should be fixed, and the iron feet of the door frame should be welded firmly with the embedded iron plate.

3、安裝門(mén)扇主體，注意一定要保證保溫卷簾門(mén)與墻體結成整體，封閉性要做好，然后粉刷洞口及墻體。粉刷完畢后，門(mén)縫應均勻平整，開(kāi)啟保溫卷簾門(mén)應該自由輕便，不得有過(guò)緊、過(guò)松和反彈現象。

3. When installing the main body of the door leaf, it is important to ensure that the insulation roller shutter door is integrated with the wall, and the sealing should be done well. Then, the opening and wall should be painted. After the painting is completed, the door seam should be even and flat, and the opening of the insulation roller shutter door should be free and light, without any tightness, looseness, or rebound.
