RESIDENTIAL BUILDING - INSULATION

• Ensure that insulation is applied to the band/rim board above the basement walls.
• Determine that crawl space is adequately ventilated and the floor system is insulated to R-19 with the vapor barrier facing the warm side.
• Ensure that all basement walls exposed to the exterior temperatures are insulated to R-9 and faced with an approved vapor barrier.
• Ensure that all penetrations in the basement walls and ceiling are sealed with approved sealants.
• Ensure that any access to crawl space is sealed with a tight fitting gasketed panel.
• Ensure that any plumbing pipes projecting into the crawl spaces are protected against freezing and all duct work within the crawl spaces are properly insulated.
• Ensure that all exterior walls are insulated to R-13.
• Ensure that all wall penetrations, i.e., windows, pipes, etc., are chinked and sealed.
• Ensure that all fire stopping is in place, i.e., between floors, bulkheads, under tubs, fireplace flues, pipes, etc.
• Ensure that ventilation baffles are installed for blown-in insulation and where cathedral ceilings are used.
• Determine that adequate attic ventilation is provided, i.e., gable end vents, ridge venting, soffit venting, mechanical venting, etc.
• Ensure that sprinkler pipes are blanketed.
• Ensure that roof is insulated to R-38 and that mechanical equipment and ducts do not hinder this performance requirement.
• When an attic area exceeds 30 square feet and has a clear height of 30 inches or more, then determine if a readily accessible attic access opening measuring at least 22 by 30 inches has been provided.
• Verify that insulation shields are installed around all class A & B flue vents and extend at least 2" above the insulation in the attic.
