When looking at a large area, the emissivity of various surfaces must be considered. Most materials found on the surface of buildings will have a relatively high emissivity but there will still be noticeable differences in the perceived image due to a change in surface material.
This can be overcome by a detailed knowledge of the building under investigation. Some metals and glass can reflect infra-red radiation and apparent hot spots can be a reflection from a hot object near by.
A thermal imager detects and displays surface temperatures. The surface temperature under normal conditions is the result of heat energy conduction through the walls from a heated object or internal room. Moisture is an excellent conductor of heat and when insulation (like glaswool or open cel insulation) is damp it will become a conductor rather than an reflector or insulator. A measure of the ability of a surface to radiate energy as measured by the ratio of the radiant flux per unit area to that of the radiated by a black body at the same temperature.
Example: Black Body = 1.00
Red rough house brick = 0.93
C3 ADF foil = 0.055
Moisture is an efficient conductor of heat. Wet or damp renders your insulation and or your mission not to be detected useless.
C3 Anti Detection foil is not hygroscopic

Scalpel Each scalpel is individually packed in sterile packaging. These are extremely sharp. Please dispose of them carefully. Scalpels are ideal for taking cuttings as they produce a clean sterile cut on the plant. This reduces the chance of infection and decreases rooting time. Scalpels are sold in boxes of 10.
