Metal Roofing Va Energy Efficient roofing system
Radiant Therma Vent
This system introduces ventilation to the roof and attic. It reflects radiant heat with the use of a radiant barrier and it stops the conduction of heat in the summer and cold in the winter into the attic space.
How it works: the drip edge at the lower edge of the roof has an air gap below it where air can enter. As the air under the roof is heated by the sun, and as hot air rises exiting the vented ridge vent then cooler air is drawn in at the eave. As long as hot air rises (we don’t think a law can be passed to stop that) then this becomes an automatic air ventilation machine. There is a Styrofoam panel with grooves in it to enhance the air movement and to create a thermal break where cold or heat cannot be conducted into the house.
The home above is located in Charlottesville, Virginia and you can see how the panels are being installed right on top of the foam panel. The radiant barrier is under the panel and the air pathway is under the panel as well.
We will be happy to show you a prototype of this system where we actually disassemble a model of this unique but effective approach to ventilating older homes.
