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.\u003c\/p\u003e\u003cp\u003eThis 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. \u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003cp\u003eExample: Black Body = 1.00 \u003c\/p\u003e\u003cp\u003eRed rough house brick = 0.93 \u003c\/p\u003e\u003cp\u003eC3 ADF foil = 0.055 \u003c\/p\u003e\u003cp\u003eMoisture is an efficient conductor of heat. Wet or damp renders your insulation and or your mission not to be detected useless.\u003c\/p\u003e\u003cp\u003eC3 Anti Detection foil is not hygroscopic\u003c\/p\u003e","brand":"C3 ADF Sheeting 100M x 1.2m CL","offers":[{"title":"Default Title","offer_id":60362839163264,"sku":"HL-48824","price":305.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/4643\/2669\/files\/8247f370_1670a494-31e1-4789-b401-5df2aca601ab.jpg?v=1794327103","url":"https:\/\/highstreethydro.com\/products\/c3-adf-sheeting-100m-x-1-2m-cl","provider":"HIGHSTREETHYDRO","version":"1.0","type":"link"}
