# About this reference > Who publishes this, why a specification reference is not a price guide, what is counted about readers, and how the figures may be reused. Source: https://flooringcompared.com/about Documents last read: 2026-11-09 A specification reference is worth something only if its edges are declared. This page is the declaration: what it covers, who compiles it, what conflict of interest sits behind it, what it counts about the people who read it, and what it may be used for. ## What this covers The edges of this reference are set in the release file and printed here out of it, so the two cannot come apart. The category: rigid core vinyl plank flooring (SPC and WPC). The geography: United States. The basis: manufacturer-published technical data sheets, installation instructions and warranty documents. Three things are named as outside it, in the release's own words: flexible LVT and glue-down sheet vinyl; laminate, engineered wood and solid wood; and any figure not carried by a cited manufacturer document. “Any figure not carried by a cited manufacturer document” is not a product category but a sourcing rule: a figure with no cited document behind it can have come from anywhere. A boundary of category is not a claim about a market. Every maker absent from the table below is absent because nobody here has read its documents yet, and for no other reason: there is no bar a brand clears to be included, no brand has been left out on a judgement about its products, and the eight makers here are what has been read rather than what exists. ## Who publishes this This reference is compiled and published by a materials-only flooring retailer in the United States. That is a conflict of interest and it is disclosed on every page rather than on this one, because a disclosure a reader has to go looking for is a disclosure designed not to be found. The publisher's trading name is withheld at present by its own decision. What is withheld is the name alone: the relationship is stated everywhere, unchanged. The practical consequences are two, and neither is hidden here. There is no link from this reference to the publisher's shop, and there is no published contact channel, so corrections cannot be sent to us directly. What stands in place of a channel is structural: every figure carries a link to the manufacturer document it came from, so any reader can check any cell against the primary source without needing us at all. No manufacturer pays for inclusion, no product is ranked, and no figure on this site is our own measurement. The publisher sells flooring materials; it does not sell or arrange fitting, and this reference publishes no labor figures and no offers. ## Why this is not a price guide There are plenty of pages that will tell you what a floor costs, and this is not one of them. The question here is narrower and, for the decisions that go wrong, more useful: what does each product’s maker actually declare about it, and under what condition does that declaration hold? That distinction is what makes 56 fields worth normalizing. Two planks can carry identical thickness, wear layer and warranty length and still be governed by installation rules that do not line up, and the widest published gap in this release is the max run without a transition, where one maker's 80 stands against another's 40, and a maximum run one declares as a length another declares as an area. Those are the numbers that decide whether a floor lasts, they are published, and nobody collects them into a form where they can be read side by side. ## What is counted Page views are counted with Google Analytics, along with how long each page stays in view. That is the whole of it. There is no filter, no comparison box and no form anywhere on this site. Nothing a reader could type into, and so nothing typed to collect. A reference whose argument is that a number should say where it came from does not get to collect its readers’ inputs quietly. No advertising pixels, no cross-site identifiers, no personalisation. Each page view is tied to a random identifier in a cookie on this site, never to a name, and nothing counted changes what any reader is shown. ## Reuse The figures are facts declared by their manufacturers and are not ours to withhold. Quote them freely, and carry the citation and the condition with them, because a maximum run without its declared unit, or a slip figure without its test method, is not the fact but the shape of the fact with the meaning taken out. The selection, arrangement and wording here are ours; the machine-readable release is published at [spec-v1.json](/data/spec-v1.json) so that quoting it correctly is easier than quoting it badly. Every crawler that identifies itself is allowed everywhere on this site, including the ones that train models and the ones that answer questions. We would rather these figures were quoted correctly than paraphrased badly. ## State of this release How much of this reference exists is published as a count of cells, not described in prose, and the four states are counted apart from one another because they are four different findings: a figure that was read, a figure the maker does not publish, a figure two readings disagreed on, and a figure nobody has read a document for yet. *Release contents, counted from the published dataset.* | Measure | Count | | --- | --- | | Brands | 8 | | Products with a page | 16 | | Cells in the record | 896 | | Cells published | 590 | | Fields the maker does not declare | 222 | | Cells held back pending resolution | 20 | | Cells no document has been read for yet | 64 | [How the figures were read](https://flooringcompared.com/methodology) · [what each field means](https://flooringcompared.com/fields) --- Every figure on this site is a manufacturer’s published declaration, reproduced with a link to the document it came from. Quote it with its citation and its condition: a maximum run without its declared unit, or a slip figure without its test method, is not the fact. --- This reference is compiled and published by **the operator of this site**, a materials-only flooring retailer in the United States. It sells the category it describes here. No brand pays for inclusion and no brand is ranked; no figure attributed to a manufacturer is the operator’s own measurement, and each is reproduced with the document it came from. The counts and coverage figures are this reference’s own arithmetic over those declarations. The operator sells flooring materials. It does not sell or arrange fitting, and this site publishes no labor figures and no offers. Page views are counted with Google Analytics, along with how long each page stays in view. There is no filter, no form and no comparison box on this site. Nothing a reader could type into. [What is counted](/about#measurement).
