Many
different
kinds of siding can be put on exterior walls. They are as follows: wood
siding, drop siding, board siding, channel rustic siding, bungalow
siding, dolly varden siding, log cabin siding, tongue & groove
siding, and bevel siding. The number of siding courses is determined by
measuring the distance from the underside of the soffit to 25 mm or
more below the bottom plate on the foundation wall, and dividing this
distance by the maximum weather exposure of the siding. The maximum
weather exposure is calculated by subtracting the minimum siding
overlap or headlap from the overall width of the siding. The minimum
headlap is 25 mm, for 89 mm and 140 mm siding widths, and 32 mm for
widths over 140 mm. From the foundation wall location, layout the
siding vertically on the exterior wall over the sheathing building
paper. Adjust the siding exposure downward (and overlap upward) on the
layout so that the bottom of the siding board that passes over the top
of the first floor window coincides with the window cap. Do not
increase the exposure to help layout the siding because 203 mm is the
maximum exposure allowed. All of the siding will have with the same
exposure and overlap. The siding may have to be treated with water
repellent also. Mark the siding foundation wall location every
600
mm horizontally along the wall. Snap a chalk line at the marks and nail
a furring strip 10 mm above the line to provide support for the
starting course. Place the butt end of the siding along the chalk
line. Nail the siding to the bottom plate below each wall stud. Measure
the amount of overlap along the top of the siding and snap a chalk line
to mark the location of the butt edge of the second course of siding.
Apply the rest of the siding so that the vertical butt joints between
the boards are staggered, fit tightly together, and fall on a wall
stud. Siding should be fastened to each wall stud with only one nail.
Never nail through two or more pieces of siding on to a wall stud. The
nail should be flush (level) with the siding surface so the siding is
snug but not tight against the wall studs. The siding ends can be made
to fit tightly together by making each board length 2 mm too long and
by bending and snapping the board into place in the wall. Cut each
siding board that passes under a window sill, to fit the sill groove
shape. Set siding on drip caps that are installed over doors and
windows. Trim the last course of siding to fit under the eaves and
apply a molding if necessary. Outside corners can be modified in 3
ways. Cut the siding to length and miter the corner edges before
application, cover the corners with corner boards before applying the
lengths of siding that will butt into them, and cut and apply the
siding lengths so they will be even with the outside corners of the
building before covering the corners with metal corners. |
