Double Wall Insulation
Insulated Double Walls
Boost insulation on new walls from R-19 to R-30. Create a 2x10 wall (2x6 exterior structure with 2x4 interior). You may achieve similar benefits by using 2X10 studs instead of the composite double wall. However, you may lose the 'thermal break' created by a small air gap left between the two stud system. That same air gap also has an audio advantage in breaking sound waves to keep your home quiet and comfortable. Think of an inefficient house as wearing a flannel shirt, an efficient house with an added sweater, and a high performance house with the shirt, sweater, and a parka. In addition to energy savings, you get better sound protection since the double wall diffuses the sound waves.
Offset the interior studs to diffuse sound waves or run horizontal spacing boards between the walls. The deeper sill at windows is a great visual feature. Spray-in insulation gives you the best performance, because it fills all of the crevices. Select a 'Formaldehyde-Free' insulation to save on air quality and health. A carpenter can frame about 6 lineal ft of wall / hour with 16" on center studs, plus both top and bottom plates and fasteners.
The ROI Calculation is based on adding interior studs prior to the sheet rock, so you only pay once for finishing/painting. For a 30' long wall 8' high, this factors in an additional $500 labor, $250 insulation, and $150 studs, and savings of $10 a month. Plus consider the tax credits.
Tax CreditsThe American Recovery and Reinvestment Act (ARRA) provides you with a 30% Tax Credit for Insulated Double Walls that are put into service by the end of 2010. This tax credit item is only for existing homes, not new construction, that is your primary residence and it includes ONLY the cost of materials and NOT installation.
