IWINDOW RETROFIT GLASS SYSTEM

iWindow - Retrofit Glass System For Commercial Buildings

Without replacing the existing glass or altering the exterior framing system, iWindow enables rapid glazing retrofits of commercial buildings - at a small fraction of the cost compared to full window replacements. iWindow can improve commercial building energy efficiency and acoustical performance.

iWindow Benefits

  • Can increase Center-of-Glass thermal performance of ¼” clear single glazing from R-value 1.0 up to R-value 6.7 (U-factor 1.0 to 0.14)
  • Can reduce noise transmission (see lab tests)
  • No change to the existing outer glass or framing, preserving the exterior appearance of a building
  • Can improve inside glass surface temperatures, making it more comfortable to work and sit near windows and allowing temperature setpoint changes that reduce HVAC costs
  • SeriousGlass low and high solar heat gain glass packages create custom- tuned solar control according to a building’s unique location and orientation
  • 96 to 99.6% UV blockage reduces fading and damage to interior furnishings

iWindow Features

  • Low-emissivity glass coatings optimize solar gain control by climate and building orientation
  • Easily secures to vertical supports of existing storefront, curtain wall or window wall to transfer the glass load to the vertical mullions
  • Snap-on cover conceals fastener heads to preserve clean, unobtrusive frame sight lines
