System estimator

Size your crawlspace materials before you buy.

Enter your floor sections and wall runs to get a quick estimate for floor rolls, wall rolls, seam tape, wall tape, term bars, and screws. The wall recommendation assumes wall tape + term bars + screws together.

Floor sections

Add each rectangular floor area you want covered.

Length (ft)

Width (ft)

Floor roll preference

Default to 10'6" × 100' floor rolls Switch to 10'6" × 200' floor rolls

Start with 100' rolls for easier handling. Switch to 200' rolls when you want fewer seams and larger continuous runs.

Walls

Wall length is measured around the outside of your floor sections. The wall roll estimate assumes 5'3" × 100' wall rolls.

Use the perimeter of my floor sections — wall length is calculated automatically.

Wall perimeter (ft)

Wall height (ft)

Support pillars

Pillars add seam tape and wall (butyl) tape. Enter how many pillars and their total linear feet (add up the distance around each pillar).

Number of pillars

Total linear feet of pillars

Standard estimating basis includes 6-inch overlaps, 10% material allowance, and wall attachment using wall tape, term bars, and screws. Seam tape is estimated at 1 roll per 250 ft² of crawlspace plus 1 roll per 4 pillars; wall (butyl) tape at 1 roll per 50 linear feet.
