Hos emmision
The Swedish accredited laboratory RI.SE performed measurements of volatile organic compound (VOC) emissions on Kerrock panels in accordance with the “M1 Emission Classification of Building Materials: Protocol for Chemical and Sensory Testing of Building Materials,” version 18.6.2024, as well as testing for carcinogenic substances (EU Regulation No. 1272/2008, Annex VI, categories 1A and 1B), formaldehyde, ammonia, and sensory acceptability.
The measured VOC values are significantly below the permitted limits, and no carcinogenic substances were detected; Report: O100785-1334956-2.
The test results confirm that Kerrock meets the requirements of the high M1 class for registration with Rakennustieto Finland. We are currently registered in the M1 classification process with Rakennustieto Finland.

LEED
LEED (Leadership in Energy & Environmental Design) is a leading international system, or program, for evaluating and certifying building design, while promoting best global practices in construction and the use of building products. It helps professionals improve the quality of building products and reduce environmental impact. The green building sector is rapidly growing, and therefore owners and contractors are increasingly recognizing the benefits of LEED certification.
- Kerrock is a material with a long service life; products can be relocated and reused after the end of a building’s lifecycle
- Products made from Kerrock can be fully recycled and converted into raw materials suitable for manufacturing new products or for use in other industries. Larger pieces (parts of façade panels, cladding, etc.) can be reprocessed using Kerrock adhesive into other products, such as furniture
- Kerrock contains up to 40% recycled content
- Kerrock is manufactured from materials sourced from nearby local suppliers, thereby reducing environmental impact
- Kerrock adhesive used for bonding products is fully cured at the end user and does not emit volatile organic compounds (VOCs)
- Kerrock products are highly suitable for indoor use, as they practically do not emit volatile organic compounds (VOCs); confirmed by testing in an independent laboratory RI.SE (Report No. O100785-1334956-2)
- Kerrock is a composite material compliant with the REACH directive and does not contain substances listed as SVHC (Substances of Very High Concern)
- None of the components used in the production of Kerrock panels contain phthalates, heavy metals, chromium (VI) compounds, or other carcinogenic substances
- Kerrock sheets are self-extinguishing and, in the presence of an external fire source, do not emit toxic gases (Report No. 2011-1241-1, EXOVA Warringtonfire)
