Читать книгу More Straw Bale Building - Peter Mack - Страница 16

A well-built bale wall creates an unbroken wall of high insulation. In a traditional frame wall, the space between the studs might be insulated to R- 12 or R-20, but the wooden studs themselves only offer approximately R-1 per inch, or R-5.5 for a common 2-by-6-inch stud. The thermal efficiency of the building is broken by these regular “cold bridges.” Infrared photographs of frame homes taken on a cold day will show the outlines of the studs as cold strips on the interior wall surface. Problems can also arise in frame walls with settling and improper installation of various insulation materials, creating cold gaps. In a bale wall, only the window and door openings create cold bridges.
