Permanent product record
Material and use
Project suitability, engineering performance, fire compliance, and installation requirements must be confirmed for the specific building and current manufacturer specification.
What it is
K-Roc HF is Kingspan’s current US insulated wall-panel range for applications requiring a mineral-fiber core and documented fire performance. The official catalogue lists embossed and non-embossed skins, several profiles and multiple panel thicknesses.
It may be evaluated for sensitive commercial or industrial wall conditions, including selected washdown environments. Fire-resistance duration depends on the complete tested assembly and installation requirements; a product-family name or thickness alone does not establish a project rating.

Chronology
First verified Technical Library capture of the current US catalogue record. This is not evidence of product launch or manufacturer change.
Technical Library record updated: August 30, 2026. This does not establish a manufacturer launch or change date.
Refurbishment research
No sufficiently reliable identification guidance is currently held. Product appearance alone may not establish the installed generation, market, or specification.
Product relationships
No evidence-supported direct replacement has been recorded. A similarly named product must not be assumed compatible.
Provenance
This library is a research and reference resource. Verify current suitability, availability, engineering performance, certification, warranty, and installation requirements with the manufacturer and the project design professional before specification or construction. Archived specifications do not represent current requirements.
