DiamondBack Stucco Foam

Our patented design eliminates the need for firring strips ( which adds $1800 in extra costs to a 2000 sq foot home), saves time and is much more efficient when building with a stucco wall system.

This photo depicts how a proper installation of a radiant barrier on a stucco wall system should be installed. Firring strips are installed to keep the stucco foam from contacting the reflective film which negates the performance. On a 2000 square foot home the additional labor and materials for installing these firring strips 16" on center is around $1800. Eliminate this cost, speed up your job and have higher performance by specifying Diamondback Stucco Foam as seen below.

Shown here is the back side of our patented Diamondback Stucco Foam wall system. This proprietary shape on the back side of the stucco foam allows for minimum contact when used in conjunction with our high performance Thermal Control Membrane reflective insulation product and eliminates the need for the installation of firring strips. There is no higher performance wall system in the world than this combination.

Architects specifying this thermal wall system have reduced the HVAC capacity by 40% on their projects.

Phoenix Christian Assembly New Gymnasium, kitchen and chapel tower

New gymnasium wrapped in Diamondback Stucco Foam and Thermal Control Membrane.Our products allowed the church to not run 10 tons of the 20 tons installed to cool this structure. NOTE: You must downsize the HVAC at least 40% when using this construction detail in addition to the TCM and powered venting installed in the attic.

1500 Square foot residential addition in Paradise Valley Arizona has the HVAC downsized 50% due to the effectiveness of Thermal Control Membrane in the attic and around the walls.

The two 1 ton mini split condensing units can be seen on the slab. 1500 square feet cooled by two tons! An addition of this size would typically have at least 3.5 tons.
