THIS OLD HOUSE® 2018 IDEA HOUSE Includes Superior Walls® Xi Plus Foundation
A precast concrete Superior Walls® Xi PlusTM foundation has been installed as the starting step for the THIS OLD HOUSE® 2018 IDEA HOUSE in Narragansett, R.I. The energy-efficient wall panel system will be featured in both the October and November/December 2018 issues of This Old House magazine.
“This year we’ve been involved in the construction of two projects for This Old House and it’s been quite an honor working with their team,” says Jim Costello, president of Superior Walls. “For both the THIS OLD HOUSE 2018 IDEA HOUSE and the Net Zero House we supplied dependable, energy efficient Xi Plus foundations.
“These remarkable precast concrete panels are installed in just one day, so the teams at Sweenor Builders could get started immediately with the construction process.”
According to Jeff Sweenor, President and CEO of Sweenor Builders, the Superior Walls system got the project off on the right track. “The beauty of the Superior Walls system is that we got a perfectly straight, level and square foundation with which to start the Idea House,” says Sweenor. “Impressively, the Superior Walls team was able to accommodate all our requests to customize the foundation. They created the openings we needed and even incorporated spaces for hurricane tie downs.”
Xi Plus Foundations
As opposed to concrete blocks or poured concrete, precast Xi Plus concrete panels from Superior Walls are created in the manufacturing process with DOW® THERMAX™ insulation covering rigid foam insulation. The panels are available with a built-in insulation value of R-21.3 and can be insulated up to R-42+.
The wall panels used in the project provide R-values that meet or exceed energy conservation values from both the IECC and the IRC, and the Xi Plus wall panels can help in the construction of an ENERGY STAR® qualified home. The Superior Walls Xi Plus wall panels in the Idea House have achieved the NGBS Green Certified Product designation provided by Home Innovation Research Labs.
Creating the Idea House
The panels were custom manufactured off site in indoor production facilities at Superior Walls by Weaver Precast. This eliminated any on-site soil contamination, such as the form oil used for poured concrete walls.
“The Superior Walls foundation in the Idea House provides added living space for the future homeowners,” says Sweenor. “In addition to a storage area, we’ve created a home theatre, gym and sauna room in the basement. As a bonus, the sturdy foundation is also extremely energy efficient.”
The Craftsman-style THIS OLD HOUSE 2018 IDEA HOUSE will be featured in This Old House magazine, plus the house will be showcased in segments of the 2018-2019 season of the Emmy Award-winning TV series This Old House.
The 2,700-square-foot cottage was designed by Union Studio Community Architecture & Design out of Providence, Rhode Island. Located less than a mile from the town beach, future owners of the house will benefit from the durability and energy efficiency of the precast foundation on the home.
