Sealing attic vents helps decrease house air leakage and may reduce some moisture issues in attics in hot humid climates. new code-approved unvented attics can use different types of insulation materials, however, there are specific requirements that vary by materials used and climate zone. These requirements may be complex and may increase construction and operational energy costs.
