MATERIAL PREPARATION LIBRARY

Cladding and external trim.

Choose the actual material and supply form. Each sheet identifies what to measure, which product data to collect and a purchase assumption to check.

Cladding course stock

Measure course lengths by the supplied orientation and openings.

Measure the actual supplied face coverage and divide it into the chosen courses.

Measure each panel end requiring trim and list separate joint pieces.

List all supplied continuous corner, stop and reveal bead runs.

List full trim runs and prescribed angled ends as separate cuts.

Material	Selected product data	Ordering mistake to avoid
Cladding course stock	Useful cover width, stock length and the permitted joint locations.	Nominal width can overstate effective cover in an overlapping profile.
Cladding overlap panels	Actual panel size and specified side or end lap.	Gross panel area cannot replace effective cover area.
Cladding end trim	Usable stock lengths and explicitly supplied trim allowances.	Panel area does not determine the number or length of end trims.
Render bead stock	Stock length and whether a particular run may be joined.	A continuous corner longer than one stock piece cannot be solved by total length alone.
Exterior trim board	Stock length, actual profile dimensions and reserved cutting gap.	Outside corner geometry may make the purchase blank longer than the visible inside run.
