Gentek’s Regency 400 vinyl window lineup has become a go‑to choice for homeowners, builders, and designers across the GTA. They’re engineered for strength, styled for modern architecture, and built to handle Canadian weather without compromise.


If you’re thinking about new windows, here’s why the Regency 400 deserves a spot at the top of your list.


Gentek 80 SQ FT Windows. Designed to deliver strength, energy efficiency, and stunning curb appeal, the Regency 400’s expanded sizing means you can have bigger, brighter spaces without compromising on performance.
Go big with Gentek’s 80 sq. ft. windows. Uninterrupted views, natural light for days, and interiors that feel instantly elevated.

🌤️ THINK BIG: Oversized Windows Up to 80 sq. ft.


One of the standout features of the Regency 400 is its expanded sizing — offering window configurations up to 80 square feet. That means:


  • Bigger, brighter interiors

  • Wide, uninterrupted views

  • More natural light

  • A modern architectural look that instantly elevates curb appeal


And unlike oversized windows of the past, these are engineered to stay strong, stable, and energy efficient — even at maximum size.

  • Ladder

  • Custom shapes


Grids can be placed between the glass for easy cleaning or applied externally for a more traditional look. It’s all about matching your home’s character — or creating a new one.

Enhance your windows with interior grids available in Bright White and Pewter. Choose from Colonial, Perimeter, and Double Perimeter patterns, enclosed within the glass for effortless maintenance.

🧊 Glass Options Built for Canadian Weather


Your windows are only as good as the glass you choose. Gentek offers high‑performance glass packages designed to improve comfort and reduce energy loss, including:


  • Low‑E coatings to reflect heat

  • Argon gas fills for insulation

  • Double or triple glazing

  • Sound‑reducing options

  • UV protection to prevent fading


These upgrades help keep your home cooler in summer, warmer in winter, and quieter year‑round.

With rising energy prices, choosing high‑performance windows is one of the smartest upgrades you can make. Over time, the savings add up — and the comfort is immediate.
