Origin, Nature and Safety
1. What is the difference between Preserved Moss, Moss Wall and Lichen?
Let's clarify technically: what is commercially called a "Moss Wall" or "Preserved Moss" in the design world, is actually the precious Nordic Lichen (Cladonia Stellaris) in our premium products. We chose to use Lichen because, unlike common flat undergrowth moss, its three-dimensional bushy structure is the only one capable of guaranteeing true certified sound-absorbing performance.
2. How is Moss preserved? Does it contain harmful chemicals?
Our 100% natural Moss is preserved using a green process: the life sap is replaced with an organic mixture based on salts, vegetable glycerin, and food-grade pigments. This technique stops the plant's life cycle, transforming it into an inert material, safe for health and with zero VOC emissions (Volatile Organic Compounds).
3. Does a moss wall generate odors in the work environment?
No. Green Habitat's use of purified vegetable glycerin prevents any release of bad odors. In the first few days after installation, the environment will be pervaded by a slight and pleasant aroma of a Nordic forest, which will naturally dissipate within a couple of weeks, leaving the Moss Wall odorless.
4. Can it be toxic if touched by children or pets?
It is a totally Pet & Child Friendly green wall. Unlike indoor living plants (e.g., Monstera or Ficus) that hide toxicity risks if ingested, our preserved Moss has no contraindications. The salts and food colorings guarantee absolute safety even in case of accidental contact.
5. Is there a fire certification to install it in the Contract sector?
Absolutely yes. The presence of natural salts inside the plant acts as an ecological fire shield. The Moss panel has passed the tests of the Istituto Giordano obtaining the official fire reaction classification Class B-s2, d0 (UNI EN 13501-1 Standard), confirming low flammability and zero dripping in the event of a fire.
Environments, Installation and Limits
6. Can the Moss Wall survive in the dark? Does it need specific lighting?
It proliferates at 0 Lux (total darkness). From the moment it is preserved, the moss ceases chlorophyll photosynthesis. It requires neither sun nor phyto-stimulating LED lamps. This makes it the ideal architectural solution to enhance basement spaces, panoramic elevators, windowless bathrooms, and dimly lit lobbies.
7. Is it suitable for exterior facades or damp shower cabins?
NO, its use is strictly Indoor. Any contact with the elements (frost, rain) or direct splashes of water (e.g., inside a shower) would dilute the glycerin and natural salts, irreparably compromising the integrity of the preserved moss. If kept indoors, its longevity can be measured in years.
8. How to prevent the natural color of the moss from fading?
The secret to preserving the chromatic intensity (which lasts on average from 8 to 10 years) is to avoid direct and prolonged exposure to solar UV rays. It is essential to place the wall away from direct sunlight (large windows) and intense contact heat sources (such as radiators or stoves). Ambient light and office LEDs, however, are perfect.
9. Do I need to reinforce the plasterboard before applying the Moss panels?
No reinforcement is necessary. Our moss modules (standard 75x75 cm format) boast a featherweight that ranges between 5.3 and 5.9 kg per sqm. Thanks to Dry Tech technology, dry anchoring using direct screws on the plasterboard is safe and very fast.
10. Can the moss adapt to curved walls or columns?
Yes, flexibility is a basic feature. The substrate of Green Habitat Moss panels is a fire-retardant MDF layer just 3mm thick. This thinness gives it exceptional malleability, allowing the "seamless" cladding of circular pillars, reception desks, and complex geometries.
Maintenance, Health and ROI
11. 40-60% Humidity: Is it a weakness of Moss or an advantage for humans?
It represents the ultimate indicator of healthiness. International bodies (such as the WHO or EPA) declare that a relative humidity range between 40% and 60% is vital to prevent the spread of pathogens and protect the respiratory tract in offices.
The Moss Wall acts as a Natural Hygrometer (Bio-Hygrometer). If it feels soft to the touch, you have physical confirmation that the building's air is healthy. If it becomes crispy, it is an alert that the environment (perhaps due to HVAC) is excessively dry and harmful to people.
12. What happens if the preserved moss dries out and hardens?
It is not dying and does not need to be replaced. The hygroscopic nature of the moss causes it to stiffen if the humidity drops below the 40% threshold. Golden rule: never mist it with water. It is sufficient to raise the humidity level in the air (by opening windows or using a humidifier), and the moss will return soft and spongy within a few hours.
13. Is there a risk of dust accumulation or insect proliferation?
The protective glycerin gives the moss an antistatic effect, which physiologically repels dust micro-particles. Furthermore, not needing water, soil substrate, or light to live, it does not create the ideal habitat for parasites, fungi, or insects. For an extraordinary post-construction cleaning, a puff of cold air from a distance is sufficient.
14. Do Moss Wall projects help with ESG certifications (LEED, WELL)?
Yes. Integrating preserved moss into corporate fit-out projects constitutes a powerful lever for sustainable architecture:
- WELL Building Standard v2: It brings direct benefits to requirements related to Acoustic Comfort (Sound) and natural design (Mind / Biophilia).
- LEED v4.1: It supports the parameters of Water Efficiency (not needing irrigation) and Indoor Environmental Quality (guaranteeing the absence of VOCs).
15. How does moss maintenance affect Total Cost (ROI)?
The fundamental parameter in Corporate Real Estate is the TCO (Total Cost of Ownership) over 5 years. Choosing living walls entails huge constant operating costs (irrigation, pumps, pruning, phyto-stimulating lighting). Preserved moss offers an extreme advantage: the management cost (OPEX) is zero. The financial commitment ends with the installation, maximizing the return on investment (ROI).
