Coverage Calculations

Siding and paneling areusually sold either by the lineal(running) foot or by the boardfoot.

To simplify cost and cover-age estimations, select theappropriate factor from thetable at right according to howthe material is priced. The fac-tors provided in the table canbe used to calculate theamount of siding required eitherin lineal feet or in board feet.

In either case, the squarefootage of the area to becovered is calculated first, thenmultiplied by the appropriatefactor.

Procedure:

A) Calculate the square footage in walls: length x width = sq. ft.

B) Calculate, and then subtract,the square footage ofopenings. Now add 10% fortrim and waste.

C) Multiply the result by eitherthe factor for lineal feet orthe factor for board feet.

D) Multiply the total footagerequired by price.

The exposed face width will vary depending onsize selected and on how the boards-and-battensor boards-on-boards are applied. Minimum over-lap is ". Determine the exposed face, then referto footnotes to calculate factor.

1 Lineal Foot Factor is derived by dividing 12" by the exposed face width.2 Board Foot Factor is derived by dividing the nominal width by the exposed face width and is based on

nominal 1" stock, except log cabin. Log cabin is based on 2" thickness. For nominal 1" log cabin, multiplyby .75.

Note: Factors do not include any allowance for trim or waste and do not apply to diagonal installations. A10% allowance (for trim and waste) should be added to the square footage required before the factors areused. Refer to Procedure at left.

Checklist for a Siding Material Specification

Select species suited to the project. List grade names, paragraph numbers and rules-writing agency. (Refer

to Grade Selector chart on back cover). Specify surface texture for exposed face. Specify moisture content suited to the project. If gradestamped, specify lumber to be stamped on back or ends.

(WWPAs Specifying Lumber [A-2] offers additional information.) Specify VG (vertical grain) if appropriate and available. Specify pattern and size (WWPAs Natural Wood Siding [TG-8] and

Paneling Basics [A-3] offer additional information.)

1 Equivalent grades, under the same paragraph numbers in WWPA Rules, are available in Idaho White Pine. Refer to Western LumberGrading Rules.

2 Western Wood Products Associations Western Lumber Grading Rules.3 West Coast Lumber Inspection Bureaus West Coast Lumber Standard Grading Rules.4 National Lumber Grades Authoritys Standard Grading Rules for Canadian Lumber.5 Some clear grades may be specified VG (vertical grain). Common practice is to ship orders as a combination of vertical and flat grain,

unless specified otherwise.6 The widely used marketing term, STK usually describes a combination of Select Knotty and Quality Knotty, sometimes marketed with

approximately 15% of the order in Quality Knotty.The grade names in bold face type are the most widely available grades. These are often specified as a grade combinationthat includes some portion of material in the next higher grade; i.e. C&Btr Select, D&Btr Select, A&Btr Cedar, 2&Btr Common, 3&BtrCommon or Std&Btr (Standard & Better).
