Outstanding performance - A point-by-point checklist


1. Maintenance-free for life

  • Dominion's window profiles are made from an exclusive, 100% virgin uPVC powder compound that is entirely lead-free.
  • This special compound gives the system better resistance to impact and discoloration.
  • Dominion window profiles are maintenance-free and will not crack, blister or warp in any climate

2. Attractive design

  • Fusion welding gives a more attractive appearance and eliminates the need for adhesives and sealants.
  • Result: a flawless, 100% watertight and airtight surface.
  • Internal walls are also welded for increased overall structural strength.

3. No Leaks, no fuss, no moisture

  • Our patented drainage system eliminates water faster and more efficiently than any other system on the market.

4. No drafts, no energy loss

  • Air tightness is ensured by triple or quadruple weather stripping (depending on window model).
  • Air, dust and dirt infiltration are virtually eliminated resulting in greater comfort and lower utility bills.

  • Dual pane, triple pane, LowE and argon gas combined to maximize your comfort.
  • The glazing bead is designed to withstand extreme conditions, including winds up to 375 km/h (235 mph).

  • Warm edge technology provides a superior insulating value and reduction of sound transmission.

7. Security-minded
