When installing a prehung exterior door, which jamb is normally set plumb and fastened first?
Answer: Hinge jamb
The hinge jamb carries the door, so it is set plumb first and the rest of the frame is adjusted to the slab.
What is a typical consistent reveal (gap) between an exterior door slab and its jamb?
Answer: 1/8 in.
About 1/8 in. all around lets the door swing freely while weatherstripping seals the gap.
What security feature should an outswing exterior door's hinges have?
Answer: Non-removable hinge pins
Outswing hinge pins are exposed on the outside, so non-removable pins stop someone from pulling them and taking the door off.
What is the purpose of kick-out (diverter) flashing where a roof eave meets a sidewall?
Answer: To send roof runoff into the gutter and away from the wall cladding
Kick-out flashing stops water from running behind the siding at the bottom of a roof-wall joint, a common source of rot.
What is the preferred way to cut fiber cement siding to control respirable crystalline silica exposure?
Answer: Fiber cement shears or a saw with a dust-collection system
OSHA's silica standard favors shears, scoring, or saws with dust collection to limit silica dust.
How should butt joints in fiber cement lap siding be handled?
Answer: Backed with joint flashing or placed over framing per the manufacturer
Manufacturers call for butt joints to be flashed behind (or set on framing) so water at the joint does not reach the WRB.
Which foam should be used to seal the gap between a window frame and the rough opening?
Answer: Low-expansion foam made for windows and doors
Low-expansion foam seals the gap without pushing on and bowing the frame, which would make the sash bind.
