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)
*Rain-screen*...Air cavity keeps siding away from wall framing allows moisture to dry

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

Why are these numbers highest at roof?

Types of Insulation Material : Batts or blankets or blown or Rigid (at Header over door) or foam expanding insulation
Header with Rigid Insulation
Insulation location : • Attic ..most critical area (as heat rises)• Exterior walls • Floors - separating unheated from heated areas• [doors & window - insulated & with weather stripping]
CRUSH LESS INSUL.
