The house that Claremore man Ken Riggs is building on Oklahoma Street may be raising a few eyebrows, but he knows what he’s doing.

Riggs is using a newer construction method and materials from a company called NUDURA, wherein homes are built with patented Styrofoam blocks, which are filled with concrete and offer increased energy efficiency and wind (tornado) resistance than the traditional “stick frame” homes.

“These homes utilize steel-reinforced concrete sandwiched between to panels of polystyrene foam,” he said. “There already are some businesses and more expensive homes in Claremore built like this — I’m wanting to make them more available to the common man and everyday home-owner.”

Currently working on a spec home using this method on Oklahoma Street, Riggs said that although the NUDURA material homes are slightly more expensive up front, they more than pay for themselves in the long run.

“The insulating capacity of the expanded polystyrene, combined with the structural strength and thermal mass of concrete makes NUDURA walls stronger, safer, and far more energy efficient than typical residential walls,” Riggs said.

Riggs, formerly the owner of Dunlap-Riggs in Claremore, currently is working on his certification to become a full-time contractor and business owner. Once he does, he plans to recommend homes built with NUDURA materials to the public.

Among the other advantages from these kind of materials are increased fire resistance, durability, and sound resistance, Riggs said.

“And homes built with these products can be built to withstand winds of up to 250 miles per hour, so they’re nearly tornado-resistant,” he said.
