How much moisture air can hold depends on the temperature, which is why they call it “relative humidity.” Here’s how it works and why it matters.
Foil blocks heat transfer best if it stays clean, is adjacent to an airspace, and the delta is large enough.

It's rare to find lighting guidelines backed up by documented field testing
In a tightly air-sealed house, a mechanical ventilation system ensures a healthy exchange of fresh air
A computer lighting model converts input (such as ceiling and counter height, fixture and lamp type, surface color and reflectance, etc.) into both 2D output showing projected fc levels at every point on a 2x2 grid (above right), and a 3D model of the room showing the effects of the lighting plan (above). Current light levels at the island (right) are more than three times the 15 fc readings taken before the kitchen remodel.
Real-world footcandle readings shine a light on the importance of recessed fixture size, lamp type, and fixture location
Many remodelers don’t know how to talk about chemical sensitivity
When a balloon loses air or depressurizes, it gets smaller (and makes a funny sound), but houses don’t roll like that
How can indoor air quality become so bad when there's penty of venting and no toxic materials?
Shingling over an old roof may be faster, cheaper, and a common practice. But some companies refuse to do it.
