Methodology
Details you can trace.
Our library connects molding questions to catalog information and its collection date. Product names, tags, options, and prices come from the source catalog. Their presence here does not mean we have independently tested a product or confirmed that it suits a particular project.
How the calculators work
Rectangular frame estimates add twice the width and height of one frame, multiply by the number of identical frames, and divide by 12 to convert inches to linear feet. An editable waste percentage increases that estimate. The 10% example is a planning assumption, not a required allowance.
Panel quantity estimates divide wall width by effective panel coverage width and round up to the next whole panel. They assume one horizontal run and do not account for openings, height, pattern matching, or extra waste.
Every calculator displays its formula and example inputs. Estimates do not optimize a cut list or determine the number of stock lengths to buy. Confirm actual dimensions, cut requirements, and stock lengths before purchasing.
Collect
Keyword research, catalog records, questions, measurements, technical references, images, and legacy URLs enter as separate source records.
Normalize
Spelling, units, names, dates, and identifiers are standardized without removing the original source value.
Match
Queries are connected to real molding entities, user intent, relevant evidence, and available products.
Merge
Equivalent phrases and duplicate intents share one canonical page instead of competing URLs.
Compose
The page receives components supported by the collected records: options from the catalog, prices from its snapshot, or a calculator with an explicit formula and worked example.
Gate
Pages missing a supported entity, unique value, provenance, useful component, or internal-link path remain unpublished or noindex.
