Materials List Revisited

[Glenn Woodward]

Gerry,
Try this.
Draw a room with single layer walls.
Make 2 walls 1 1/2" thick.
Make the other 2 walls 6" thick.
Generate a ML.

You should get 2 different entries for wall insulation.
1 for the thin wall (about 4" thick which is too thick for the 1 1/2" wall anyway) and one for the thicker wall (6" thick).

This is part of what makes me believe that the wall insulation is coming from the walls main layer and not the a cavity (if there is one - because a s you can see, you get wall insulation with a single layer wall).

Either way, doesn't really matter, it needs to be fixed.
