Reduction of Water Problems

The monolithically manufactured 3,4 or 5 sided building components have no seams where water penetration could occur.

The sandwiched wall system structure produces no dust or airborne contaminants during construction, does not allow moisture to be absorbed into the insulation or allow transmission of moisture through the envelope, which eliminates condensation on the wall surfaces.

Additionally, fiber composite connectors are resistant to thermal transfer. The result is no thermal bridging through the insulation. What this means is that during the winter there will not be any cold spots on the inside of the wall that would attract moisture to form condensation. The overall thermal performance of the wall system will maintain the same surface temperature on the face of the interior wythe as is the interior air temperature.


Reduction of Mold Problems

  • contains no consumable material within the wall which contributes to
    the propagation of mold , a growing liability in the construction industry.
  • eliminates cold or hot spots in the occupant zones
  • maintains wall temps at or near the interior operating conditions.
  • liquid water is not absorbed by the
    insulation.
  • THERMOMASS® insulated panels limit or eliminate the transmission of moisture through the envelope,
    which eliminates condensation on the wal
    l surfaces,and contain no consumable material within the
    panel for mold propagation.
  • Extruded Polystyrene Insulation (XPS) with the Thermomass System (TBS). XPS is a closed cell insulation that has the best Water Absorption (% by volume) and Water Vapor Permanence (Perm) ratings available for rigid insulation.
