## Sources

Every factual statement on a content page is backed by a source listed at the bottom of that page and marked with a numbered citation. In order of preference, we use:

1. Government and standards bodies, such as forest products research laboratories and standards publishers.
2. Trade associations and certification schemes.
3. Established reference works.
4. Companies' own published information, for facts about that company and its products.

We don't use review sites, anonymous forums or AI-generated text as sources.

## Figures

Numbers are reproduced exactly as their source gives them, with units. Where reputable sources give different values, we show both, or the range. Wood is a natural material, so published properties are averages and individual boards vary.

## Photos

Photos come from Wikimedia Commons under free licences (public domain, CC0, CC BY or CC BY-SA). The author and licence are credited under each image.

## Companies and links

Manufacturer and installer listings are built from each company's own published information and listed alphabetically. We don't publish ratings or rankings. Content pages may link to companies' websites where a product or range is relevant to the topic.

## Updates and corrections

Each page shows the date it was last updated. If you spot an error, tell us through the [contact page](https://www.misterendgrain.com/contact/) and include a source if you can. Corrections are checked against the source before the page is changed.
