重塑前婴儿和隔热院

Bob is in Melrose, MA, to update a 100-year-old home in preparation for a new baby.  Since home building and remodeling can introduce hazards into the home, Bob is looking at how to reduce unwanted toxins and select healthy alternatives.  He visits the American Lung Association's designer showhouse in West Palm Beach, FL, where EcoDecor's Bernadette Upton reviews healthy choices like using no-VOC paints, choosing natural, washable throw rugs instead of synthetic wall-to-wall carpeting, buying natural bedding and mattresses, avoiding treated fabrics, purchasing formaldehyde-free furniture, using non-vinyl wall treatments, and airing wallpaper before applying non-toxic glues.  Back in Melrose, Bob talks with homeowner Nick Beasley about the decision to purchase a two-family home and use the upper two floors for their primary residence.  Maggie Beasley shows Bob the main living areas, the kitchen they hope to safety proof, the upstairs bedrooms that need insulation and renovating, and the original beadboard room that will become a child's bathroom.  Nick shows Bob the demolition and new partition wall for the master bath.  Joe Arrigo from Resource Development Partners explains the challenges of insulating an old house and how loose-fill fiberglass insulation is blown in to achieve an R-value of 4.25 per inch or R-30 overall.
