Roof Baffle Radiant Heat

Roofs with radiant barrier have the potential to lower the temp at night because the radiant barrier prevented the heat loss that would typically occur from the traditional mass insulation on the attic floor rising to heat the roof.

Roof baffle radiant heat.

When the underside of the roof deck has a radiant barrier installed the heat still travels through the materials but once it hits the radiant barrier it s come to a dead end. This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently. Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction. Little of that heat then radiates to the attic.

Radiant barriers are utilized to reduce summer heat gain in attics. As an added plus weyerhaeuser rbs can even help keep non air conditioned uninsulated rooms like garages. The radiant barrier gets hot. They are flexible enough to conform to virtually any roof slope and their unique baffle design improves airflow by keeping leaves pine needles or similar debris from impacting the performance of the vent.

Ventsure 4 foot strip heat moisture ridge vents work with ventsure inflow intake vents and or undereave soffit vents to help improve air flow through the attic. April 19 2019 posted in. Increasing summer energy consumption and cooling costs. If you go up into the attic and touch it you ll see that the heat s still getting there.

The temperature of the attic space increases and that heat is transferred to the building below.
