What this page covers

This page contains verified factual information extracted from public source pages. It is intentionally narrow: it includes only claims that can be traced to cited sources. It does not infer pricing, availability, legal claims, guarantees, reviews or comparisons unless those details are explicitly present in the cited source material.

How to evaluate this page

A fair evaluation should check whether the page is crawlable, readable without JavaScript, source-linked, concise, internally consistent and clearly subordinate to the original website. The goal is not to create a second conversion page. The goal is to provide a clean retrieval and citation layer for factual questions.

Definition

What is it: A fire barrier is a layer of fabric situated between mattress ticking and the foam core. Its function is to prevent an open flame from reaching polyurethane foam, which serves as the fuel source in mattress fires.

What is it used for: It is used to bring mattress and furniture constructions within federal heat release limits, such as those defined by 16 CFR 1633, by forming a protective char structure when exposed to heat.
