 Thermal Control Membrane, the most effective attic insulation in the world for hot climates and the only radiant barrier with a lifetime performance warranty!  How does it work? Rather than resist the flow of heat like conventional fibrous insulation, TCM changes the direction of heat.  The results?  Lower energy consumption, doubles the life of the HVAC equipment, increases comfort Click here

 When considering a radiant barrier it's imperative that you also significantly increase the attic venting to exhaust the super heated attic air.  We've been smoke smoke testing full size homes and checking which vents work and which do not and have listed our findings on our venting page.   Click here 



TCM Roof Underlayment System: Keep the heat out before it gets into the attic.  A fraction of the cost of foam in the attic Click here


A gymnasium addition for the Phoenix Christian Assembly Church which is wrapped in Diamondback Stucco Foamtm and Thermal Control Membranetm (TCM/4).  The attic has R30 cellulose covered by Thermal Control Membran (TCM/6). This combination allowed the church to use only 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 when specifying Diamondback Stucco Foam and Thermal Control Membrane in the attic.
This just in from the pastor two years after the building was completed:

To Whom It May Concern:

     This is to verify that Horizon Energy Systems, designed and implemented their latest products on our new multipurpose building at our church, Phoenix Christian Assembly.  The products work so effectively that the building does not go over 90 degrees without using any air conditioning.  The whole building can be effectively cooled in 20 minutes.  Horizon Energy also installed German attic fans and added additional venting on the East side that also does a good job. 

               When the building was built the power company automatically increased our electric bill.  Then later they came back and reduced the budget plan by $500.00 per month.  We found Horizon Energy Systems to be of character and integrity wanting only what s best for the owner.  If you have further questions, please do not hesitate to contact me at 602-275-8085.

This 2800sq foot Phoenix home not only had high energy bills but even at this cost per month the a/c units ran non stop and at the peak of the summer could not cool below 81F.  Hot rooms, high bills, blasts of hot air out of the ducts when the units started, dust problems, duct leaks are not problems, they are symptoms of existing problems.  We have turn key solutions to all of these problems.  Our video page has examples, click here .  It all starts with an $89 home inspection.  A BPI trained home inspector will evaluate your home, identify problems and write you a succinct proposal for the solutions.  Solutions that will last for the life of your

Frank Luke under construction.  The exterior was first wrapped in  TCM and then covered by Diamondback stucco foam .



Frank Luke Completed.  The most efficient multi-family building in Arizona.

This three story assisted care center is going to be comfortable and easy to cool due to the installation of Thermal Control Membrane and our new Diamondback Stucco Foam product on the walls and attic.  This combination effectively keeps heat from moving into or out of the building through the walls.  We used a similar system when we appli ed our technology to the most efficient home ever built on ABC's Extreme Makeover Home Edition. 

Ductless Mini Split Heat Pumps


Drop your bill by significantly by eliminating the immense energy losses of running 60F air protected with 1/2" of insulation from the 140F air in the attic.  We have witnessed many cases where the tonnage has dropped by 50% with more comfort.  This isn't about compromise, this is basic physics and logic.  Every dollar you pay for cooling you get, not 60% using a ducted system.  Can be easily retrofitted at a low cost.  Up to 1 ton can be installed which uses only 110volts at 700 watts.  Call 602 867 3176 for a free estimate.

The time has come to move quickly on making decisions to reduce our consumption of finite, fossil fuels, propagate renewable energy and nurture our planet.  All of us are caretakers and have a responsibility to make changes at every level and inculcate into our children and others, by example, a move in this direction. 

We must immediately address archaic building codes which are not climate specific and begin using available proven technologies as found on this site.  We need to move now to build more energy efficient, sustainable and comfortable homes and buildings.  Our proven products will help you meet these goals.  Before building, buying or remodeling, read this web site thoroughly and please be prepared to "think outside the box".
