All organic materials will emit small amounts of formaldehyde – even if none is intentionally added. This is also the case for mineral and glass wool insulation and all alternatives containing organic material such as cellulose, straw etc.
ROCKWOOL AFB® evo is manufactured with a non-added formaldehyde binder.
To support our claim, ROCKWOOL has achieved the UL Environment’s (ULE) Formaldehyde Free Environmental Claim Validation.
For a product or material to be verified as formaldehyde free, product samples must have a measured formaldehyde emission comparable to, or below, typical outdoor air concentrations. This demonstrates that formaldehyde exposure from products labelled as formaldehyde free will not contribute airborne formaldehyde at a level greater than found in the natural outdoor environment.
The manufacturer also maintains a formalized manufacturing quality system and attests that there is
- No added formaldehyde,
- No known added formaldehyde precursors,
- No added formaldehyde polymers, and
- That no formation of formaldehyde is expected under typical product usage conditions.
