Spray-On Closed-Cell Insulation

Project: Victorian Kitchen & Bath Remodel, Episode 3, Part 2



The Queen Anne Victorian addition is ready for clapboard siding to match the existing façade and trim. Inside, the demolition is complete, the chimney stack has been removed, and a custom steel structural support has been placed where the load-bearing dining-room wall once stood. Insulation specialists explain, and begin to install, the expanding foam, closed-cell insulation. Outside, contractor Tim Berky completes a custom backerboard and transitional bed molding to match the original 1890s molding.
