Thermax Wall System

Energy efficient wall insulation systems from Dow Building Solutions maximize air, moisture and energy management within the building envelope. The THERMAX™ Wall System is a systematic approach to achieving efficiency at every level: simplified design, streamlined construction and optimized energy consumption for a reduced carbon footprint. Eliminating the need for batt insulation, gypsum and air/water resistive barrier, this three-in-one system enables architects, designers and contractors to achieve the highest standards in energy efficiency.

The THERMAX™ Wall System, featuring continuous insulation (ci), air barrier and flashings, minimizes energy use in steel stud construction by improving thermal performance, enhancing moisture control and preventing condensation by reducing air infiltration and keeping the cavity temperature above the dew-point temperature. The THERMAX™ Wall System can help design professionals meet increasingly stringent energy efficiency standards and achieve credits in the U.S. Green Building Council’s Leadership in Energy & Environmental Design (LEED) program, while maintaining the integrity of their creative vision.

System Components

Exterior Insulation

THERMAX™ (ci) Exterior Insulation minimizes thermal shorts and moderates the temperature of the wall cavity, reducing the potential for dew point condensation, mold and mildew. An integral, durable acrylic-coated aluminum facer provides a drainage plane and water-resistive barrier, eliminating the extra step of installing a membrane or building wrap.

Air Barrier

Applying closed-cell STYROFOAM™ Brand SPF (CM Series) on the interior of the steel stud walls effectively blocks air infiltration by filling gaps, cracks and penetrations. The spray foam also provides additional insulation.

Flashing System

WEATHERMATE™ Straight Flashing helps protect the wall assembly from moisture entry at windows, doors and other thru-wall penetrations, including between sheathing joints.
