原理
因為破層內的空氣外熱力傳入外牆，所以剝離位置飾表面溫度會比完整位置較高，而商技術能快捷準確指出問題飾面/混凝土的位置及範圍。
這技術能成為有效的勘察方法，原因如下:
因為破層內的空氣外熱力傳入外牆，所以剝離位置飾表面溫度會比完整位置較高，而商技術能快捷準確指出問題飾面/混凝土的位置及範圍。
這技術能成為有效的勘察方法，原因如下:
- 低成本
- 非破損性，無需接觸表面
- 節省時間
- 實質數據可作證供及陳述
- 客觀的勘察結果
Principle
Because the external heat of the air in the broken layer is transferred to the outer wall, the surface temperature of the peeling position will be higher than that of the complete position. In addition, this technique can quickly and accurately point out the location and extent of the problematic finish/concrete.
This technique can be an effective survey method for the following reasons:

This technique can be an effective survey method for the following reasons:
- low cost
- non-destructive, no need to touch the surface
- save time
- substantive data can be used for testimony and statements
- objective survey results

外牆飾面缺損分級
Grading of exterior wall finish defects 較輕微的缺損 ↓ 建議於定期檢查時，進行監察或維修▼ Minor defect↓ It is recommended to conduct monitoring or maintenance during regular inspections.▼ 
|
嚴重缺損建議 ↓ 建議立即跟進及維修▼ Severe defect recommendation↓ It is recommended to follow up and repair immediately.▼

外牆飾面缺損勘察步驟
- 選擇適當的環境和角度，於關注面進行紅外線勘察，同時拍攝普通相片作對照
- 同時在現場進行目視勘察，記錄所需的資料
- 用專業軟件進行詳細的紅外線照片分析，標出懷疑缺損的位置和範圍
- 提議跟進懷疑嚴重的缺損位置及進行維修
- 缺損的位置維修後，問題的高溫帶已消失，這證明那位置的問題已被修妥
Inspection Steps for Defects of Exterior Wall Finishes
- Choose an appropriate environment and angle, perform infrared survey on the surface of interest, and take ordinary photos for comparison
- At the same time, conduct a visual inspection on the site and record the required information
- Use professional software to perform detailed infrared photo analysis to mark the location and extent of suspected defects
- Suggest to follow up and repair suspected serious defects
- After repairing the defective location, the problematic high temperature zone has disappeared, which proves that the problem at that location has been repaired
