Vigilis-Bio VentAir Tree Shelters: Fully Soil-biodegradable with increased airflow
What are Vigilis-Bio VentAir Tree Shelters?
Vigilis-Bio VentAir are plastic-free tree shelters with perforated holes. The vented design increases airflow, ventilation and light transmission, making these tree shelters suitable for warmer or more exposed tree planting sites.
They have all the same benefits & features as standard tree shelters, but without the plastic. 100% soil biodegradable (tested to ISO 17556). No need for collection. Non-toxic to the soil (tested to EN 13432). Functional life of 5 years, followed by a further 2-3 years to fully biodegrade. All that remains after biodegradation is water & minerals.
Vigilis_Bio VentAir: Made From Plastic-Free Materials
Vigilis-Bio VentAir Tree Shelters are made from derivatives of bio-based materials (potatoes, wood & corn). The cellulose structure of these plant-based materials is used to create a bio polymer. This material is used to manufacture our vented tree shelters and they are designed to have a functional lifespan of 6 years.
Product Features: Vigilis-Bio VentAir
Flared Rim
Flared upper rim to minimise stem abrasion.
Twin Wall
Strong yet lightweight construction, with optimal strength to weight ratio. Creates a micro-climate inside the tree shelter to enhance growth.
Venting - Perforated Holes
Allows acclimatisation to external conditions by increasing airflow, ventilation and light transmission.
Break Line
Allows the tree to break open the shelter if needed. Even though the tree shelter is biodegradable, if the tree grows quickly, this feature will prevent strangulation.
Biodegradable or Releasable Cable Ties
Our tree shelters are pre-fitted with your choice of biodegradable or releasable cable ties.
Light Transmission
Transparency allows for optimal light transmission which enhances tree growth.
How are VentAir Tree Shelters packaged?
Vigilis-Bio VentAir tree shelters are manufactured with 5 different diameters (73mm | 84mm | 92mm | 102mm | 110mm). These allows the tree shelters to be ‘nested’ inside of each other in groups of 5 – saving space for storage and transportation.
The tree shelters are bundled in packs of 30 and strapped together, making it easy for you to carry them to site.
Minimal packaging reduces the amount of waste on planting sites.
Lifespan & Performance
Non-toxic UV stabilisation ensures that Vigilis-Bio VentAir Tree Shelters maintain mechanical strength for at least 6 years. After this initial 6 year period, the structural integrity of the tube starts to fail. The material will then begin to fracture and fall on to the forest floor over an additional period of 2-3 years. It will start to biodegrade as soon as it is in contact with the leaf litter, soil and/or microbes. It has been designed to compost in soil conditions.
After biodegradation, all that remains is water, biomass and minerals. No micro-plastics or toxic residues.
