Selection & Installation Guides
The working documents behind a specification: how to match components, what the tables mean, and where projects usually go wrong.
Each guide follows the same structure, so you can read the section you need rather than the whole document: what decision is being made, what data you need in front of you, how the options compare, what belongs in the submittal, and the failure modes that show up in the field. Comparison tables are built as methods — the line items to compare — rather than as our numbers, because cost and performance depend on your project and your market.
Guides that depend on factory data we have not received yet stay unpublished rather than appearing as a stub. If the guide you need is not here, ask for the selection table directly — that is usually faster than waiting for the document.
