Green Efforts:

  • All of Ostaco's doors are fiberglass which significantly reduces our requirement for wood and in turn reduces Ostaco's overall carbon footprint.
  • All of Ostaco's door slabs have a CFC-free solid polyurethane foam core!
    • What does this mean? Well, CFC stands for chlorofluorocarbon (CFC) which is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane.
    • CFC is known for its contribution to ozone depletion and as such Ostaco has made sure that our doors are CFC-free!
  • Most important is the fact that Ostaco's door systems are built to last! Invest in a quality product that will stand the test of time and rest assured in the fact you will not have to replace your door system for a very long time, if at all, reducing your waste significantly.
