thermal insulation
Let an agent explain thermal insulation, relay principles, materials, ratings and building applications from building science sources, describe the named forms, route asbestos and fire safety, and distinguish thermal insulation from electrical insulation, acoustic insulation, weatherproofing and vapour barriers.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain thermal insulation, relay principles, materials, ratings and building applications from building science sources, describe the named forms, route asbestos and fire safety, and distinguish thermal insulation from electrical insulation, acoustic insulation, weatherproofing and vapour barriers.
The reduction of heat transfer between objects by using materials with low thermal conductivity or reflective surfaces, widely applied to buildings to save energy and improve comfort, with forms the registry aliases name such as building, home and roof insulation, rigid panel insulation, cementitious foam insulation and external insulation finishing systems; materials include mineral wool, foam boards, cellulose and aerogels, rated by R-value or U-value. Some older insulation contains asbestos, and some foams raise fire and off-gassing concerns, so materials should be chosen and handled per regulations, and suspected asbestos should be assessed by professionals.
What it is for: Reducing heat transfer, especially in buildings.
It can be explain principles and materials; relay ratings and applications; describe named forms; route asbestos and fire safety.
Distinguishing features
