Infrared-GSF

Building Systems:

Infrared surveys are an exceptional non-intrusive tool for diagnosing problems with Commercial and Residential structures.
Issues related to water intrusion, insulation defects, construction quality, air infiltration and more can be seen in real-time
using current technology imagers.

Building products and materials are not always installed properly. Surveys can be performed prior to commercial operation
to help find and resolve problems before contractors leave the site.

The image at left shows a poorly constructed CMU
(concrete mansonry unit) wall. Thermal surface patterns
can reveal missing concrete at pilaster and beam
locations. Infrared is a valuable tool in verifying
construction quality in these wall systems.

The image at right shows insulation defects in a new home.
IR cameras can quickly locate these defects within wall or
ceiling spaces. This non-intrusive technique can help solve
living space comfort issues, HVAC problems, plus others. IR
is also a powerful tool when attempting to solve high
energy cost issues.

The image at left is a low-sloped roof with moisture
beneath the surface. When roof membranes leak,
rainwater enters the top layer and is absorbed by
underlying materials. Unchecked, this moisture will render
insulation ineffective and cause decay of the roof deck
materials. These defects are easily found with the IR
imager.

The image at right shows water behind this wall. Locating
the source of moisture intrusion is a primary goal of the IR
survey. No more time or money wasted tearing out walls or
ceilings just to locate the point of intrusion.

Stucco Finish System surveys can help locate moisture
beneath the surface of this popular exterior finish. No
destructive testing necessary and tenants are never moved.
The survey is totally non-intrusive. Entire multi-story
building elevations can be surveyed at once, in real-time.

EFIS (Exterior Finish and Insulating System) and conventional Stucco
systems can be surveyed to help locate moisture beneath the surface.
The image at right show indications that water is migrating down from
the roof flashing and around the window frame. You can see no defects
or staining in the visual photo.

Air infiltration / exfiltration and how it affects living spaces can be seen
with the IR imager. The images at left show a defective AC return air duct
in a single story home. Hot air is being drawn down and into the duct
from the attic, causing the system to run more than normal and perform
poorly. Inspection revealed poor sealing of the duct. This defect was easy
to fix once found.
