In our last post, we shared our first version of a cool roof ventilation system that automatically vented the hot air through a custom vented ridge vent and replaced it with cooler air through a custom eave vent.

The photo below shows our latest improvement that not reduced the labor cost but also introduced a thermal break as well as a radiant barrier. This latest improvement not only addresses all 3 ways heat is transferred, it works on any roof style including asphalt shingles.

What are thermal breaks? They are any form of solid insulation that doesn’t allow cold or hot to transfer to an adjacent surface. To demonstrate how this works I took a Styrofoam cup and filled it with boiling water. Then I took a temperature reading of the water with a laser thermometer. The temp of the water was 185 f. The temp of the Styrofoam cup was 94 f. I slid a card board sleeve on the cup and due to air ventilation under the sleeve the temp was around 72 f.

When we install our Therma vent insulation system this same principal is at work. On one test we did the temp on the roof was 165 f and the temp in the attic was 150 f. After installing the thermal breaks the temp in the attic was reduced to 103f. We thought that was amazing.

This is a video describing our custom ventilation system and its built in thermal break:https://www.youtube.com/watch?v=OX_l3e1qPMw
