CLC Exterior Cladding, Windows & Doors Installation 5

Question 1

When installing a prehung exterior door, which jamb is normally set plumb and fastened first?

Accepted Answer

Hinge jamb

Answer

The hinge jamb carries the door, so it is set plumb first and the rest of the frame is adjusted to the slab.

Question 2

What is a typical consistent reveal (gap) between an exterior door slab and its jamb?

Accepted Answer

1/8 in.

Answer

About 1/8 in. all around lets the door swing freely while weatherstripping seals the gap.

Question 3

What security feature should an outswing exterior door's hinges have?

Accepted Answer

Non-removable hinge pins

Answer

Outswing hinge pins are exposed on the outside, so non-removable pins stop someone from pulling them and taking the door off.

Question 4

What is the purpose of kick-out (diverter) flashing where a roof eave meets a sidewall?

Accepted Answer

To send roof runoff into the gutter and away from the wall cladding

Answer

Kick-out flashing stops water from running behind the siding at the bottom of a roof-wall joint, a common source of rot.

Question 5

What is the preferred way to cut fiber cement siding to control respirable crystalline silica exposure?

Accepted 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.
