Upgrade your windows
with Guardian Sun™ packages

If you are planning to replace your windows, you may quickly realize how many decisions are involved. Frame materials, colors, opening systems, glazing options… it can be difficult to know where to start.

Choosing new windows can feel overwhelming

Many homeowners naturally focus on the window frame. Yet glass represents most of the window surface, and it can play a key role in how comfortable you feel at home.

The right glass can do much more than simply let daylight in. It can help reduce heat entering through the windows on hot days, improve insulation in winter, reduce outside noise, or improve safety.

A simple way to
choose the right window glass

Guardian Sun packages are combinations of window glass technologies and features designed to help you easily choose glazing that meets your needs when replacing windows. Each package builds on the previous one, allowing you to add additional features and achieve the level of performance you are looking for.

PACKAGE

Level 1: COMFORT

The Guardian Sun Comfort package forms the foundation of your window. It combines solar control and thermal insulation to help create a comfortable indoor environment throughout the year. This means your windows can help:

  • reduce solar heat entering your home during warm days
  • retain warmth inside during colder months
  • maintain natural daylight and clear views

PACKAGE

Level 2: ADVANCE

If you want to enhance your windows further, the Advance level allows you to add additional features depending on your priorities. These upgrades can help:

  • improve safety
  • reduce disturbing noise from outside
  • or add protection against forced entry

For example, safety glass can help protect occupants in case of accidental glass breakage, while acoustic glass can help reduce noise from traffic or busy environments.

PACKAGE

Level 3: ULTIMATE

The Ultimate level offers additional specialized features to further improve everyday comfort and usability. These options can help:

  • reduce reflections on the glass
  • reduce exterior condensation
  • or make glass visible to birds.

They allow you to tailor your windows even further depending on your home environment and personal preferences.
