Job takeoff
SIP wall (structural insulated panels) takeoff
Structural insulated panels, splines and plates, then the wrap, the cladding and the interior board for a new SIP wall, from its run, height and openings.
A takeoff is the trade word for the shopping list a job produces — every material, and how much of each, worked out by its own cited calculator.

About this job
A SIP wall arrives as a kit of large panels: two skins of oriented strand board glued to a foam core, each panel as tall as the wall, joined edge to edge by a spline and locked in by a plate at the foot and the head. The panel is the stud, the cavity fill and the sheathing at once, so the rows here are fewer than a framed wall's: panels, then what goes over them outside and what lines them inside.
The panel count is the one that matters most and the one least forgiving. Panels are made to order, often cut in the factory with their openings already in, and a shortfall is a lead time, not a trip to the yard. The panel row buys every panel at full height and lists the count if every off-cut were reused, so you can see the gap between the two before the order goes in.
Outside, a SIP is still sheathing that must stay dry: the facings are wood, and the wrap and a drained cladding over it are what keep them so. Inside, the board goes straight onto the inner facing, usually with no stud to find; your panel maker states the fixing for it.
How each line reads
- Base
- What the calculator gives for these dimensions, before anything is added.
- Allowance
- Cutting waste, a lap or spare stock — named, with where it comes from, and changeable on the row.
- Adjusted
- The base with its allowance on top.
- Order
- What to buy: the adjusted figure in whole boards, bags, rolls or lengths.
The order this happens in
Quantities do not tell you the sequence, and on this job the sequence is where the money goes wrong.
- Check the slab or deck for level and square, and set the bottom plate on its sealant to the panel layout.
- Stand the first panel at a corner, plumb it, and fix it to the plate; seal and fit each spline as the next panel goes on.
- Cut or receive the openings as the layout gives them, with the lumber that lines them.
- Fit the top plate, and the cap plate where the design has one, lapping the joints at the corners.
- Seal every panel joint as the maker's details ask, then wrap the outside face from the bottom up, lapping each course.
- Fix the cladding over the wrap, on battens where the cladding needs a drained gap.
- Line the inside face with board once the services are in, fixed as the panel maker instructs.
What this takeoff does not cover
- The panel design: its thickness, facing, spline type and the headers over openings are the maker's load charts and the designer's; the panel row counts what you choose.
- The lumber that lines each rough opening, the corner and end posts, the panel sealant, tape and the long panel screws, which the maker's details list.
- Openings are not deducted from the wrap, the cladding or the board: each is the gross wall, which over-orders on a heavily glazed wall.
- Lifting: large panels may need a crane or a telehandler, which depends on the site and the panel size.
- Trims, flashings at openings, corners and starter strips, and the battens for a drained cladding.
- Taping, finishing and painting the board, and any vapour control, which the panel maker's details and the climate decide.

- Which calculators does the structural insulated panel wall takeoff run?
- 4 calculators, one to a line: SIP Wall Panel Calculator (Structural Insulated Panels, Splines and Plates), House Wrap Calculator, Siding Calculator, Drywall Calculator. Each has a page of its own with its formula and its sources; the takeoff runs them all on one set of dimensions.
- What does the structural insulated panel wall takeoff leave out?
- 6 things, each named on this page: The panel design; The lumber that lines each rough opening, the corner and end posts, the panel sealant, tape and the long panel screws, which the maker's details list; Openings are not deducted from the wrap, the cladding or the board; Lifting; Trims, flashings at openings, corners and starter strips, and the battens for a drained cladding; Taping, finishing and painting the board, and any vapour control, which the panel maker's details and the climate decide.
- Can I check a quote for this job against the takeoff?
- Yes. The structural insulated panel wall quote check reads a quote's lines against these same calculators and your measurements, and reports what it leaves out, what it adds and what to ask. It reads quantities, never prices.
