Vinyl Window Performance

Our vinyl windows are built to meet or exceed today’s high standard of energy-efficiency.

Aller-Guard® Weatherstripping

Aller-Guard® weather-stripping system resists micro-particles of pollen, fungi, mildew, dust, dirt and bacteria. It also helps keep exterior odors and gases such as carbon monoxide outside.

  • Improves inside air quality.
  • Filters more outside noise for a quieter house.
  • Reduces your energy costs.

Standard in all our windows, Cardinal’s XL Edge Spacer will give you a clear and attractive view and help to reduce your heating and cooling costs for years to come.

  • Drastically reduces heat loss over typical aluminum spacer.
  • Reduces condensation during the most severe temperatures.
  • On average, performs longer than any other spacer in the industry to give you many years of dependable service! Comes with a 20-year guarantee against seal breakage.

LoĒ-272™ and LoĒ-366™ Glass

Cardinal LoĒ-272™ glass and LoĒ-366™ glass delivers year-round performance and comfort, whether it’s -20° F or 110° F in the shade.

  • In winter, it slashes your heating costs during long winter months by reflecting heat back into the room.
  • In summer, it keeps your house cooler and your furniture, curtains, and wall coverings looking beautiful by blocking heat and 95% of the sun’s damaging UV rays.
