Insulation & Air Sealing
DuPont Tyvek ThermaWrap R5.0
This building wrap from Tyvek offers builders another option to meet the higher wall R-values required by the most recent versions of the International Energy Conservation Code. It acts as a breathable air and water barrier while providing continuous exterior insulation. Installation is achieved in shingle fashion—unlike rigid, exterior foam insulation—which reduces the potential for bulk water infiltration into the wall assembly.
