A new kind of roof-and-attic system field-tested at the U.S. Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) has been developed to keep homes cool in summer and prevent heat loss in winter, a multi-seasonal efficiency uncommon in roof and attic design.
Volume 24 of the manufacturer’s Quick Delivery Catalog offers a large selection of fan and ventilation products available on a quick delivery or quick build shipping basis. The 132-page catalog includes fans, kitchen ventilation systems, energy recovery ventilators, make-up air systems, and more.
A brochure explaining a cost-effective way to mechanically circulate fresh outdoor air within the crawl space to eliminate excess moisture is available to builders, remodelers, and homeowners.

If a house is sealed tight with spray foam insulation, it is much harder for moisture to leave the house naturally.

If space is a problem or to save time and money (up to 30 percent), monitor supply and return detectors from a single power board using InnovairFlex’s semi and fully distributed 2-to-1 sensor to power board capability.
The gold, silver, and bronze winners of The NEWS' ninth annual Dealer Design awards in the Ventilation Product category not only help the air to circulate in a building, but also help HVAC contractors install and service them better and easier.
