Topic 2 – Apply Hardboard and Vinyl Siding

Hardboard and vinyl siding can be applied vertically or horizontally.

Hardboard

Hardboard siding is made from compressed wood fibres and is resistant to cracking, warping and shrinking. It should be stored flat and straight, in unheated areas to prevent drying out. Siding should be stored off the ground to avoid moisture absorption.

Hardboard accessories include:

1. Starter strip
2. Joint moulding
3. Outside corners and corner posts
4. Inside corner posts
5. J-moulding
6. Caulking
7. Touch-up Paint
8. Nails

Vinyl

As vinyl siding expands and contracts more than other products due to temperature changes fastening is done in the centre of the nailing slots. Nailing is done so that the siding can move. Do not nail flush. Vinyl siding is cut with a circular saw with a fine tooth blade installed backwards.

Vinyl accessories:

1. Corner posts
2. Starter strip
3. J-channel
4. Undersill trim
5. Drip cap
6. Beltline trim
7. Mounting plates

Estimating Vinyl Siding

Total wall area is used to estimate how many square feet of vinyl siding is needed. The formula can be modified to use the building perimeter plus the wall height and rim joist.

Wall area = P × (Wall height + Rim Joist height)

The gables can be calculated as the area of a triangle and added to the wall area.

(A= ½ b × h)

• Carpentry, study the chapter 66 “Aluminum and Vinyl Siding”
• Canadian Wood-Frame House Construction, study the sections “Metal and Vinyl Sidings” up to and including “Hardboard Siding”

Answers:

1. 6 mm if applied over sheathing, and 7.5 mm if applied to furring or framing at 400 mm O.C. (9.27.10.2-1)
2. Batten strip (9.27.9.3-2)
3. 25 mm (9.27.9.3-3)
4. 5 mm, caulked, suitable moulding (9.27.9.5-1)
5. 3 mm (9.27.9.5)
6. Venting gap
7. Individual metal corners and a metal corner post
8. 200 mm
9. 1. Get starter strip straight and level
   2. Ensure siding is completely “locked” into course below
   3. Allow gaps for movement due to temperature changes
10. 600 mm
11. 1. Perimeter = (46’ + 25’) x 2 = 142’
    2. Total Wall area = 142’ x 10’ = 1420 SF
    3. Area of openings = 125.618 SF
       1. Net wall area (Siding required) = 1295 SF
12. 1. Wall Area = 164’ x 11.333 = 1858.6 SF
    2. Gable Area = 5.333’ x 32’ = 170.7 SF
    3. Gross Wall Area = 2029.3 SF
    4. Area of Openings = 210 SF
       1. Net wall area (Siding required) = 1295 SF
