This page provides technical reference documentation for design teams specifying preserved moss installations. Fire ratings, material safety data, and environmental conditions are drawn from supplier certification and internal testing. For project-specific documentation or assembly coordination, contact us directly.
Specifications & Compliance
Fire Performance
UNE-EN 13501-1:2019 Classification: B-s1, d0
We carry preserved pole and flat moss products that are tested and certified to UNE-EN 13501-1:2019, the European fire safety standard, by our supplier. This includes evaluation for flame spread, smoke production, and flaming droplets.
-
B = Very limited contribution to fire
-
s1 = Minimal smoke production (best category)
-
d0 = No flaming droplets or particles
⚠️ Important: Certification applies only to moss materials adhered with approved fire-safe adhesives on inert substrates. Design teams should coordinate with us if flame-rated assembly is required. May support fire strategy when specified as part of a rated assembly; verification with AHJ required.
Material Safety
-
Preserved using non-toxic, glycerin-based solutions
-
Free of heavy metals and hazardous solvents
-
No active plant material, no allergens, mold, or microbial growth
-
VOC documentation available on request; project teams to confirm against WELL v2 requirements.
Acoustic Contribution
Preserved moss has natural sound-dampening properties due to its porous structure and variable density.
-
Suitable for improving reverberation in enclosed spaces
-
Not a substitute for engineered acoustic assemblies
Moss may be used in combination with absorptive cores or acoustic-rated substrates for enhanced performance.
Environmental Conditions
Preserved moss is stabilized and does not grow or require light. Its longevity depends on environmental consistency.
Ideal Conditions:
-
Relative humidity: 40–60%
-
Temperature: 18–24°C (65–75°F)
-
Low to medium exposure to airflow and direct sunlight
Avoid installations in areas with HVAC vents, direct sun, exterior exposure, or frequent physical contact.
