A New Roof-and-Attic Design System Turns Out to Be Efficient

A brand new type of roof-and-attic system tested at the Department of Energy’s Oak Ridge National Laboratory manages to keep homes cool during summer and warm in winter. That multi-seasonal versatility is something brand new in roof and attic design and the history of construction industry.
The newly-tested system uses controls for radiation, convection and insulation, which includes a passive ventilation system pulling the air from the attic into  an inclined air space above the roof. That improves the efficiency to a great extent.
Owing to that system, the heat, that would otherwise have gone into the house, is carried up and out. The good news is that the new system design can be retrofitted with almost all roofing products, as the design is based on the use of foiled covered polystyrene insulation, fitting over and between rafters in new construction or can be attached on top of the already existing shingle roof system.
In the nearest future the system is going to be upgraded to become even more cost-efficient. That is why the scientists keep working on designs with lower initial installation costs and some further reduction in the costs, overally.
