Possibilities for Wetting of Cellulose Insulation Part 2

Relative Humidity, Temperature, and Moisture Content This is Part 2 of a two-part series on cellulose insulation and moisture. Cellulose insulation is a hydrophilic material, meaning that absorbs moisture readily. Under certain conditions condensation dampens cellulose insulation causing permanent damage due to shrinking, slumping, and very slow drying. Moisture adsorption into a hydrophilic material, expressed as …

Hygric Buffering & Cellulose Wall Insulation

This is a two-part blog about hygric buffering, cellulose wall insulation, and moisture problems in high-performance buildings. Why not to install cellulose insulation in deep wall cavities Cellulose shrinks, slumps, and dries very slowly after wetting. Deep wall cavities are have more risk because the outdoor side of the wall is colder than shallower cavities. Voids left by …
