 Key Benefits
- Clean, Lightweight, Easy To Install
- Class A / Class 1 Fire Rating
- Thermal R-Values Included (see chart below)
- Saves Energy and Money
Typical Thermal Values for TempShield™ Double Bubble Products:
Thermal resistance measurements have been made according to the most recent test revisions using a calibrated hot box operated in accordance with ASTM C 976. Analysis of results was done in accordance in ASTM C 1224. The R-values observed are highly dependent on method of installation.
How Radiant Heat Transfers Through Roofs
 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 aluminum 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 97% of all radiant heat.
TempShield™ will reradiate only 3% of heat in which it comes in close physical contact, compared with the approximate 90% reradiation of ordinary building materials, at the same temperature.
