Dow Chemical Co. and residential homebuilder D.R. Horton on Thursday will hold a national rollout of the ⿿Powerhouse⿝ ⿿ a new kind of roof shingle that⿿s also a solar power system.

The event will take place at D.R. Hortonâ¿¿s Spring Mesa project in Arvada.

The shingle , made by Dow (NYSE: DOW), based in Midland, Mich., is called the Dow Powerhouse Solar Shingle. Its rollout will start in Colorado and spread to a dozen other states in the next year, according to the company.

D.R. Horton (NYSE: DHI), based in Fort Worth, Texas, and one of the largest builders in the Denver area, is offering the shingle to homebuyers at its Spring Mesa project in Arvada.

Gov. John Hickenlooper will join with Jane Palmieri, vice president of Dowâ¿¿s solar division, and Scott Davis, president of D.R. Hortonâ¿¿s Colorado division, to introduce the new shingle.

In an Oct. 4 announcement, Dow called its new solar shingle ⿿a revolutionary new roofing product that combines the performance and protection of a conventional asphalt roof with an integrated photovoltaic (PV) system that powers the home. It is designed to install, look and function in a way that has never been done before.⿝

The solar shingles are designed for homeowners who want solar power, but donâ¿¿t want to install solar panels on their roof, the company said.

⿿We learned from the consumer is that they value the look of their homes because it is an expression of who they are,⿝ Palmieri said in the announcement. ⿿Homeowners want, expect and deserve a solar product that they can be proud to display. And Powerhouse makes that possible.⿝

Dow didnâ¿¿t say how much the new shingles will cost or how much power they can generate. The company did say it intends for the shingles to be cost-competitive and for the total cost of the solar roof to be less than the combined cost of a conventional roof and supplies of conventional power.
