adding an aluminum facer to a 1-inch piece of EPS (expanded polystyrene)
CCHRC has just released a report on the effectiveness of reflective insulation in a cold climate. The insulation, which has a reflective surface, is commonly used in hot climates to reflect heat from the sun away from a building. For example, a home in Florida could add it to the roof decking to divert heat from the attic insulation and save on air conditioning.
But our researchers found that the insulation is less effective in a cold climate because it doesn’t add much r-value to an already well-insulated building.
