    Why do we use polypropylene?

    Polypropylene is a perfect material for our products.

    • Complete impermeability – Unlike concrete or metal constructions, polypropylene products will stay airtight for a century. Polypropylene isn’t affected by corrosion or erosion.
    • Polypropylene is comparably stronger than polyethylene. For example, cellars made from polyethylene require a metal frame inside to keep them from deforming. Our Kellari cellars use polypropylene shelves as such frame making the structure 100% polypropylene.
    • Polypropylene is maintenance free. Unlike metal it will not corrode and doesn’t need painting. It will not rot like wood and doesn’t need any protective coating. On top of that it’s completely food-safe. It can come in contact with food with 0 effect on it and it doesn’t release any fumes like, for example fibreglass.
    • Polypropylene is incredibly easy to work with. Extrusion welding is used to produce our cellars Kellari. Thanks to this method, polypropylene can be easily modified and equipped with anything. And all this without loosing strength. Unlike concrete which can’t be modified and looses airtightness even quicker if anything is screwed onto its walls, anything can be welded and screwed on to polypropylene with no loss of strength. And unlike metal, the seam doesn’t weaken the structure as re-welded polypropylene is as strong as its original form.
    • Low weight. Structures as big as cellars or bunkers are quite heavy and would be difficult to transport. However, producing a cellar from polypropylene reduces its weigh and makes transportation, loading and construction easier.
