Home Improvement Expert™ Checklist
Description
Many homes have vented attics that get very hot in summer and cold in winter. Converting an attic from vented to an unvented provides an opportunity to create a temperate space for heating and cooling equipment located there to operate more efficiently while also reducing infiltration of moisture, dust, pollen and pests year-round. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and health benefits possible from a quality installed unvented attic.

Home Improvement Expert™ Checklist
Description
Many home have inadequate insulation and excessive holes, cracks, and missing air barriers resulting in unwanted heat loss in cold weather, heat gain in hot weather, and infiltration of moisture, dust, pollen, and pests year-round. Air sealing leaks and adding insulation between the attic and the home is one of the most cost-effective measures to improve your home’s energy performance. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and health benefits possible with quality installed attic air sealing and insulation.
