Six topics cover the whole reference. Each one opens with a short explanation of what falls inside it, then lists every note filed under it.

### IN[Insulation & Air Sealing](https://bkgreenstone.com/topics/insulation-and-air-sealing/)

How heat and air actually leave an older house, and what changes inside a wall or roof once you slow them down.

### WD[Windows & Doors](https://bkgreenstone.com/topics/windows-and-doors/)
