Q: I understand that fiberglass batt insulation can allow air to move through it and that this air movement degrades the insulation's R-value. Two causes I've heard about are wind-washing at the eaves and convective loops that can start in a wall cavity on really cold days and wick warmth from...
Fantech’s Kitchen Ventilation System contains all the components needed to build a custom range hood: a stainless steel hood liner, a remote inline fan, and an optional inline silencer.
High-volume exhaust hoods can create negative pressure in a tightly built house, which can cause backdrafting of gas-heating appliance flues.
Part of Jenn-Air’s new Glass Collection, the 32-inch JXP5032WS Perimetric Hood looks more like a flat-screen TV than a kitchen ventilation appliance.

Q: While the IRC has approved the use of certain "hot" unvented attics, it seems that asphalt-shingle manufacturers still recommend that their shingles be installed over vented roof assemblies. Does this mean that shingle manufacturers will void their warranties if the roof deck is insulated with...
Q. My client's metal fireplace is supplied by a makeup air system with a built-in circulation fan. This fan - which plugs into an accessible outlet - is triggered by a heat sensor in the fireplace. While effective, it's also very loud. To reduce the noise, I'd like to replace the fan's on/off...

The eaves of a home can expose the structure to the ravages of wind-driven rain on two fronts: when soffits are blown out during a storm, and when winds of 90 mph or greater drive water through vented soffits. Effective December 2006, the Florida Building Code requires soffit systems to be able to...
In the hot, humid South, it's not enough to install high-efficiency air conditioning. Dedicated dehumidification, along with impeccable attention to sealing the building enclosure, is required. Researchers at LSU exhibit three practical systems that balance performance and cost in the "LaHouse"...
