EcoUrban, the redevelopment firm spearheading the project, says one of the highlights is the use of high performance SPF insulation made by NCFI Polyurethanes that effectively seals all mechanical and electrical openings throughout the house, according to SprayFoam.com. This provides a leakage rate of under 10 percent as well as excellent air quality. Seven additional homes are on the planning board. MHMSM.com first reported on this trend last year in ‘Some Say the Future for Manufactured Homes Is Downtown‘ by Eric Miller.
