Читать книгу More Straw Bale Building - Peter Mack - Страница 82

In earlier times, leaky windows, doors, walls, roofs, and floors kept relative humidity indoors below problem levels. Those same homes also required more energy to heat, because the heated air escaped the building through all these leaks, dissipating into the atmosphere. As better windows, doors, insulation, and building practices — especially the use of continuous plastic vapor barriers — began to make houses more airtight, the need grew to prevent moisture from migrating directly through the walls.
