Sometimes, this is just
air sealing, which only needs 1-inch or greater thickness.
Summary:
Air sealing have gained significant traction as an effective alternative to cool roof coating, as proper sealing of attic floor and ceiling with weatherstripping and insulation prevents air leakage from interior of spaces
Assessments from the SRI Energy staff let them know if the home needs insulation, duct sealing,
air sealing, windows or heat and air system replacement.
AltusGroup, a partnership of 21 North American producers offering proprietary structural and architectural precast bearing C-Grid carbon fiber reinforcement, has published a technical brief explaining continuous insulation and
air sealing requirements and techniques for building envelopes in order to meet ASHRAE 90.1 requirements and realize energy savings.

The aging wooden structure made
air sealing difficult.
Air sealing takes a bit more explanation, some of which we'll get into next month.
They are more comfortable and quieter because of tight

air sealing, and energy-miser appliances to knock your energy use to the ground." A deep energy retrofit may require drastic changes, like putting on a new roof or replacing all the doors and windows.
When doing a retrofit, the major tasks are usually
air sealing, adding insulation, and upgrading your heating and cooling systems, Rudy says, and what you do first matters.
