A: Cork comes primarily from the bark of cork oak trees (Quercus Suberin), mainly grown in Portugal, Spain, Algeria, and Morocco. The harvesting process is sustainable, as trees can be harvested every 9-14 years without being cut down, making it an environmentally friendly choice.

A: Yes. Cork harvesting actually benefits the environment. When bark is stripped, it triggers the tree to absorb more CO2 during regeneration, making cork products carbon negative. Trees can live for over 200 years while being harvested multiple times.

A: Cork spray installations can last 25+ years with proper application. The product comes with a 12-month workmanship warranty and a 10-year product warranty, demonstrating its long-term durability.
