2 Finishes many options Walls wood shakes, shingles, board & batten (vertical), plank lap (horizontal), T1-11 ply, vinyl, fiber cement, aluminum, stucco.&.Brick (masonry) shown above Roofs wood shakes, shingles, asphalt shingles, metal standing seam or corrugated, clay or cement tile, slat, single ply at flat roof....

3 System to Remove water Gutters / Roof Drains (Leaders) or Down Spouts DS. French drains (gravel trench) w/ Rain chains

4 * Details Weather protection – a Moisture System insulation (& V.B. vapor barriers) sheathing weather barriers Venting Flashing Cladding (finish material)

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

6 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)

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

8 8 Brick veneer on wall is a rain screen

9 Flashing...at window head and at sloped sill [Window in section view]

10 Frame Building Section

11 * Weather Protection System Walls & Roof Insulation (w/V.B. vapor barriers) Sheathing (OSB - CDX ply.) Weather or Moisture barriers Venting (air space / dry moisture) Flashing (water away & drip edges) Cladding (finish material)

12 ...In the Walls Plumbing, electrical & Insulation (with V.B. vapor barriers)

13 Insulation (& V.B. vapor barriers) Attic 1. Air gap for venting b/w insulation & sheathing 6. Roofing felt or MB (moisture barrier) 2. & 4. Insulation (batt or rigid) 3.Vapor barrier (on warm side of wall or roof) 5.Drywall Finish wall 6. MB 7. Roof (shakes)

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

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

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

17 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.

18 ...on the walls Weather protection system = enclose house Isometric of an exterior wall with CLAPBOARD SIDING

19

20 Type of Siding: noted on elevation dwgs. Seen in section dwg. fianl layer Wood Shingles or (Shakes which are more random because they are split wood )

21 Type of Siding: Wood Shingles or (Shakes which are more random because they are split wood ) Shiplap wood siding Stucco

22 * Shingles Beveled Clapboard siding Or board & batten

23 * energy saving Flashing at Roof Stepped overlapped

24 Brick Wall (Masonry) ….on CMU or on wood framing –most common
