        "text": "For existing homes, common wall insulation types include blown-in cellulose or fiberglass, and spray foam insulation. Blown-in materials are often installed by drilling small holes in exterior walls and filling the cavities, making them suitable for retrofits without extensive demolition. Spray foam offers excellent sealing properties and a high R-value, but typically requires more access to wall cavities. The best choice depends on your home's construction, budget, and desired R-value, as well as accessibility.",
