Chapter 6: Exterior Finishes For Wood Light Frame Construction

Question 1

Protects the building structure from the weather; installed soon after roof framing is completed and sheathed.

Answer 1

Roofing underlayment

Question 2

_____ (in shingle fashion) prevents water from running underneath.

Answer 2

Overlapping

Question 3

Applied before siding but after framing and sheathing are complete; protective layer intended to repel water and reduce leakage of air; materials are same #15 felt used for roofing underlayment or an asphalt-saturated paper with similar water resistive properties; bottom-up, shingle fashion.

Answer 3

Moisture barrier/water-resistive barrier/weather-resistive barrier

Question 4

What are the different components of the exterior wall assembly?

Answer 4

Eaves
Drip edge
Fascia
Soffit
Ventilation strip
Gutter

Question 6

The part of a roof that meets or overhangs the walls of a building

Answer 6

Eaves

Question 7

A wooden board or other flat piece of material such as that covering the end of the rafter

Answer 7

Fascia

Question 8

The underside of rafter, interior to the fascia

Answer 8

Soffit

Question 9

Above the soffit, beneath the rafter

Answer 9

Ventilation strip

Question 10

Beneath the drip edge, transports water away from roof underlayment

Answer 10

Gutter

Question 11

A synthetic, airtight sheet material with water-resistive and air-resistive properties used as a substitute for asphalt-saturated felt or building paper to provide a protective layer in an exterior wall assembly.

Answer 11

Housewrap

Question 12

What is the difference between an eave and a rake?

Answer 12

An eave is a horizontal roof edge, while the rake is a sloping roof edge. (These both, however, occur before a roof can be shingled.)

Question 13

Insulation applied under sheathing; improves air-tightness and reduces energy loss.

Answer 13

Spray foam

Question 14

Constructed with insulated foam panels applied over the roof sheathing, or with spray foam or rigid foam insulation boards applied below the sheathing, in between the roof rafters.

Answer 14

Unventilated roofs

Question 15

Prevent water from seeping through gaps around the edges of window and door components

Answer 15

Flashings

Question 16

Exterior cladding materials applied to the walls of a wood light frame building (wood boards, plywood, wood shingles, metal or plastic materials, fiber-cement panels, brick or stone, or stucco)

Answer 16

Siding

Question 17

A length of wood or metal attached to a masonry or concrete wall to permit the attachment of finish materials using screws or nails; any linear material used to create a spatial separation between a finish material and an underlying substrate.

Answer 17

Furring strip

Question 18

Allows water that seeps through the siding to readily drain out of the assembly rather than soak further into the wall; permits rapid drying of the siding should it become soaked, and enhances the wall’s capability to dispel water vapor that could otherwise accumulate

Answer 18

Ventilated/rain-screen cladding

Question 19

Roof flashing (material that prevents water seeping in and causing damage) that is installed at the leading edge of the shingle near the gutter.

Answer 19

Drip edge
