TempShield® is used as insulation against radiant heat transfer and can be used to its greatest advantage in instances where radiation is the predominant means of heat transfer. It is the bright aluminumized film surface of all TempShield® products that gives it its insulating properties. This happens in two ways:
TempShield® is an excellent reflector of all long wave radiant heat that strikes it - reflecting up to 95% of all radiant heat.
TempShield® will reradiate only 5% of heat in which it comes in close physical contact, compared with the approximate 90% reradiation of ordinary building materials, at the same temperature.
