Air-Sealing Tips for Efficiency That Lasts // Part 4: Protect Your Air Barrier
This is part 4 of a series that describes how to air seal the most difficult parts of buildings. A service cavity and vented rainscreen promote durable airtightness.
An important factor in the airtightness of a building, and its energy efficiency, is the amount of infiltration allowed through closed windows and doors. Typical old double-hung windows are especially prone to infiltration. [continue reading]
A reflective-insulation system consists of a low-e surface, like aluminum, which is installed facing an enclosed air space. Enclosed air typically has an R-value of about R-1 per inch, but by reducing the radiant-heat transfer ... [continue reading]
The idea behind venting to remove moisture is to allow it to escape out. Unfortunately in humid climates, it's much more complicated. [continue reading]
It is virtually impossible to achieve the standards of the 2009 International Energy Conservation Code (IECC) by accident, let alone those of the 2012 IECC, which is even more stringent. The 2012 IECC reaches into almost every part ... [continue reading]
