11. Insulating Concrete Forms Rigid plastic foam forms Hold concrete in place during curing Serve as thermal insulation after the concrete sets Image Courtesy of: www.pouredfoundations.com

12. ICF Benefits Energy savings Qualifies for a tax credit Increases interior comfort Controls moisture, air leaks, mold, and pests Reduces sound transmissions Ease of finishing the basement Drywall can be nailed directly to foam Cost competitive with poured concrete Environmentally friendly

13. ICF Drawbacks Installation costs may be higher than traditional concrete Insect problems may occur if installed incorrectly Relatively unknown to officials and inspectors

31. Insulation Types Blankets Standard “Pink Panther” insulation Available in standard sizes Loose-Fill Same material as blanket insulation Blown into hard to reach areas Rigid-Foam Very effective in tight spaces and cold climates Up to twice as insulating as blanket insulation Foam-in-Place Same material as rigid-foam insulation Used around window and door frames

35. Window Frames Metal Frames Light and almost maintenance free Very poor insulating material Composite Frames Same structural and thermal properties as wood Resist moisture and decay Fiberglass Frames Can be filled with insulation Superior thermal performance to wood or vinyl Vinyl Frames Good thermal performance and low maintenance Tendency to crack in temperature extremes Paint fades in sunlight Wood Frames Insulate fairly well Require a lot of maintenance Susceptible to moisture and decay

36. Window Glazing and Glass Gas Fills Heat-Absorbing Tints Insulated Low-Emissivity Coatings Reflective Coatings Spectrally Selective Coatings

37. Doors

38. Exterior Doors Steel skin with insulating core Provides higher R-value than solid wood door Weatherstripping further increases the R-value

39. Miscellany

40. Air Sealing Prevents heat from escaping through cracks in the wall Air sealing techniques Air barriers Block air movement through a wall Airtight drywall Caulking Weatherstripping

41. Moisture Control Keep untreated wood from touching soil Provide ample drainage Install air sealing gaskets Install insect shields Image Courtesy of: www.energysavers.gov

42. Ventilation Removes air pollutants and moisture Three basic strategies Natural ventilation Air escaping through cracks and vents Whole-house ventilation Controlled air movement through fans and duct systems Spot ventilation Controlled air movement through localized exhaust fans
