Calculating the required amount of furring strips for a project, such as installing cladding or siding, can be straightforward based on a general rule linking the area of the surface to be covered to the linear feet of strips needed.
Understanding the Basic Calculation
According to common practice, the calculation for furring strips often follows a simple ratio relative to the area of the surface you are covering.
- General Rule: One linear foot of furring strips is typically needed for one square foot of cladding or siding.
This rule provides a quick estimate for material requirements based on the total surface area of the wall or ceiling.
Applying the General Rule
To apply this rule, you first need to determine the total square footage of the area where the furring strips will be installed.
- Measure the Area: Calculate the square footage of the wall, ceiling, or other surface requiring furring.
- Example: If a wall is 10 feet wide and 8 feet high, the area is 10 ft * 8 ft = 80 square feet.
- Apply the Ratio: Use the 1:1 ratio (1 linear foot of furring per 1 square foot of area) to estimate the total linear feet needed.
- Example: For an 80 square foot wall, you would estimate needing 80 linear feet of furring strips (80 sq ft * 1 linear ft/sq ft = 80 linear ft).
This method provides a baseline quantity. Always consider adding a little extra for cuts, waste, and potential adjustments.
Key Information About Furring Strips and Battens
While the calculation rule focuses on the ratio of linear feet to square footage, other characteristics are also relevant:
- Furring Width: Furring strips typically come in widths ranging from 1-1/2″ to 3″. The chosen width might depend on the specific application and desired air gap or fastening surface.
- Battten Lengths: If your project involves battens (often used in combination with furring or as a type of siding itself), they generally come in lengths of eight feet. This information is useful when planning cuts and minimizing waste.
Summary Calculation Table
Here's a simple illustration of the general calculation rule:
| Surface Area (Square Feet) | Estimated Furring Strips Needed (Linear Feet) |
|---|---|
| 50 | 50 |
| 100 | 100 |
| 250 | 250 |
This table is based directly on the general rule that one linear foot is needed per one square foot of cladding or siding area.
This basic calculation method helps in estimating the quantity of material needed for your project.
