Being Green

Krestmark is dedicated to responsibly using resources and leaving the smallest footprint on the environment. We take a comprehensive approach to environmental stewardship, including:

  • Reycling — Our process minimizes our use of nonrenewable resources.  In addition, every vinyl and aluminum window we manufacture contains some recycled material.
  • Responsible Procurement — Krestmark uses sustainable sources and works with vendors who practice responsible harvest and replenishment.
  • Reducing Energy Consumption — Most Krestmark Vinyl windows with LowE glass and Argon gas meet Energy Star® criteria for all regions. Environsealed Windows™ guarantee lower energy bills, a lower environmental impact and, most importantly a greener future.
