The ultimate weather barrier

Whatever the rigours of the elements (wind, rain, cold, or heat), this window profile system gives you the best protection and the greatest comfort a window can provide. Its remarkable performance is the result of attention to the smallest detail in the quest for product quality, and a manufacturing process that is uncompromising from the moment it starts with virgin 100% uPVC powder until the thickest profile walls in the industry are produced.

Maintenance-free for life

  • The 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 discolouration.
  • The window profiles are maintenance-free and will not crack, blister or warp.

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.
  • Inside and outside design accessories.

No leaks, no fuss, no moisture

  • Our patented drainage system eliminates water faster and more efficiently than any other system on the market.
  • You no longer have to worry about potential water damage to your windows.

No drafts, no energy loss

  • Airtightness is ensured by triple or quadruple weatherstripping (depending on window model).
  • Air, dust and dirt infiltration are virtually eliminated.
  • Result: greater comfort—and lower utility bills.
  • Frame provision prevents the crushing of the bubble weather strip.

Multi-beneficial frames

  • The multi-chamber profiles have more chambers than any competing product.
  • Transition from hot to cold inside the structure is gradual. Our system provides superior thermal insulation—and the frame is distortion-proof.
  • Multiple air chambers provide excellent sound reduction.

Your choice of glazing

  • Depending on the model, glazing of different types and thicknesses can be applied (3/8” to 7/8”).
  • The glazing bead is designed to withstand extreme conditions, including winds up to 375 km/h (235 mph).
  • Located inside, the glazing bead provides greater security and facilitates any glazing replacement.

Security-minded

  • Opening mechanism and high-security multipoint lock parts are firmly fastened in screw boxes and stay secured.
  • The exclusive screws are specially designed for uPVC.
  • All screws install through a minimum of two walls for greater stability.

Designed to make life easier

  • Depending on the model, casements open a full 90° and sashes tilt in for easy cleaning.
  • Opening mechanisms and lock parts come in a corrosion-proof finish for greater durability.
