Product safety

Is the product safe for food contact?

Definitely! We’ve done special research for safety. The materials used for production meet appropriate standards and hold relevant certificates. The product is fully suitable for food and human contact.

What other attestations and certifications do NAWI Design’s cellars hold?

 In order to guarantee the highest quality and safety of our product, it went through many tests before it was released for sale.

We tested i.a.:

  • Structural strength
  • Laminate strength
  • Waterproofness
  • Anti-slip properties
  • Non-flammability
  • Quality and selection of materials

Can the cellar structure withstand the weight of the soil?

Yes! And this is one of the biggest advantages of our product. Thanks to the robust construction, we can put the cellar fully in the ground, avoiding the “mole mound” effect. The mentioned strength is guaranteed by the cylindrical shape of the body, proper installation in the excavation, preparation of a foundation slab and dry concrete backfill.
