Window glass (flat glass/float glass) has different chemical composition and melting point than container glass and CANNOT go in curbside recycling bins. It must be taken to specialty flat glass recyclers or construction waste facilities. Before recycling old windows, consider having them professionally maintained — regular cleaning can extend window lifespan significantly and reduce the need for premature replacement. For hard-to-reach or multi-story windows, professional exterior window cleaning services help preserve glass quality and identify damage early.
Window glass recycling diverts construction waste from landfills and recovers silica for new glass production. Recycled flat glass saves 30% of the energy needed to produce new float glass. Proper window maintenance and cleaning also reduces environmental impact by extending the service life of existing windows.
