Reduce water vapor penetration into the wall from the outside in warm weather.
Dow cavity wall insulation.
Special 16 width makes it easy to fit between brick ties in cavity wall applications.
Keep the wall cavity warmer than non insulating sheathings in cold weather.
From dow building solutions.
Thermosetting resins from dow can be used as an alternative to traditional formaldehyde based resins for binding mineral fibers in the production of insulation blanket products that go into building insulation systems and specialty insulation.
Result in less of an opportunity for moisture to condense within the wall.
An extruded polystyrene foam insulation board with square edges on all four sides.
The ashrae prescriptive continuous insulation requirements for steel framed above grade walls recognize this phenomenon and in most climate zones call for a layer of continuous insulation ci to be added to the assembly to help stop the steel thermal shorts that can decrease the energy efficiency of the wall system.
