Blown-in or sprayed insulation should be marked in inches on markers installed for every ____ square feet of attic space?

The correct answer is: 250

The correct answer is 250 square feet. In Massachusetts building codes and guidelines, it is specified that when installing blown-in or sprayed insulation in attics, there should be marking indicators for the depth of insulation. These markers must be placed at intervals of 250 square feet to ensure that the correct insulation thickness is achieved and maintained throughout the attic space. This practice helps in achieving energy efficiency by ensuring that the insulation material is adequately distributed and can provide the expected thermal resistance. This standard is crucial because proper insulation not only improves energy efficiency but also contributes to the overall comfort of the building by maintaining stable indoor temperatures. Additionally, correct insulation levels have implications for safety and compliance with energy codes set forth by local and state regulations. Failure to adhere to the correct marking intervals could lead to inconsistent insulation depth, which may compromise energy performance and lead to potential moisture issues.
