Detail Layers-of weather barrier System Vapor Barrier Insulation Sheathing Moisture Barrier Flashing Siding

Flashing often a soft metal that can cover the gap and direct water away from wall or roof used at intersections (and/or with a Drip edge)

1” AIR GAP *Rain-screen* ...Air cavity keeps siding away from wall framing allows moisture to dry

Brick veneer on wall is a rain screen 8

* Insulation Resists heat/air infiltration = Insulation Symbol is a Looping line for Blanket or batt insulation Rigid Insulation Symbol is criss-cross lines Insulation Resists heat/air infiltration = R value (the higher the # the better) *

Why are these numbers highest at roof? R 38 at ceiling or rafters R 21 in walls R 30 at floor Energy Code Why are these numbers highest at roof?

Header with Rigid Insulation * energy saving Types of Insulation Material : Batts or blankets or blown or Rigid (at Header over door) or foam expanding insulation

Insulation location : Attic ..most critical area (as heat rises) CRUSH LESS INSUL. Insulation location : Attic ..most critical area (as heat rises) Exterior walls Floors - separating unheated from heated areas [doors & window - insulated & with weather stripping]
