Thermography for building façade inspection

buildingphysics-banner.jpg

Thermal imaging is a simple, non-intrusive technique that is generally used to locate the so-called 'weak' points in the building envelope. This could be in one or more of the following forms; missing insulation, air leakage, thermal-bridging, presence of moisture, etc. Thermography is considered a cost-effective solution and is being widely employed these days for energy savings, building audits, facilities management, envelope tightness, etc.

Certain international standards;


•    ASTM E 1186 - Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier Systems

•    BS EN 13187 - Thermal performance of buildings qualitative detection of thermal irregularities in building envelopes - Infrared method

Are abided in conducting thermography testing and local green building regulation;

 

•    EHS/Trakhees for warehouse and industrial developments, mandate to perform envelope tightness testing for air-conditioned spaces using thermal imaging techniques.

 

At Buildingdoctor,  we employ qualified thermographers and high-resolution equipment to make sure we come up with accurate results during our thermography surveys.

Thermal imaging for (sandwich panel) roof inspection

Sandwich panel roof constructions are generally a great way to have an insulated and water and air-tight roof. However, the gaps between adjacent sandwich panels are often ignored during the construction stage. These small gaps provide passage for air movement. Air leakage is a major source of energy loss considering most of the buildings in the Middle East region are provided with air conditioning units.

 

Furthermore, the hot and humid air from outside starts to condense due to the air leakages which can cause dripping. This brings an ideal condition for moisture development and mold growth in the building which further leads to permanent damage to the ceiling and other spaces. The moisture may also lead to structural damage to the roof elements by corrosion.  

Replacing the entire roofing system can be an expensive job whereas finding the root cause of the problem can be a rather easy solution. The damaged sheet metal roof system can severely damage underlying false ceilings as well. Using a thermal camera, it is practically possible to ‘see’ and pinpoint the defects.

We have provided many reliable inspection reports to our clients which has helped them solving the issues with the roof in a cost-effective manner. Inspections are generally done to prevent issues, or can also be helping to settle disputes between different parties in the construction process.

The thermography inspections can be employed for complete building inspection or specific parts of a building façade such as roof and side wall panels.
