Where is the best place to install radiant barrier in the attic?
• One problematic technique is to put radiant barrier directly on the underside of the roof sheeting. What happens in any attic that is not extremely well ventilated is that the surface of the radiant barrier gets very hot and the heat is then convected into the air of the attic causing the attic and its insulation to get quite hot. This is only true in an attic with a pitched roof. Flat roof homes can really benefit from a RBS attached to the bottom. • To see the results of RBS testing on four indentical, unoccupied homes, click here.

Here, the radiant barrier does the bulk of its work by preventing the infra-red energy from being absorbed by the porous insulation. However, laying a single layer of a reflective surface makes the RBS vulnerable to the inevitable settling of dust on the surface. This application begins degrading from the day it is installed and continues until it is com
