Glass Options
The types of glass used in the window unit have a big impact on performance. Here’s how Cascade and Milgard compare:

Glazing refers to the panes of glass within the insulated glass unit.
Most standard windows have double pane construction.
But triple glazing adds another layer foroptimal insulation.
Cascade windows are available with triple glazing.
Milgard also offers triple glazed options on select designs.
This really cuts down on heat loss through the glass.
- Low-E Coatings
Low-emissivity or Low-E coatings help reduce heat flow in and out. There are two types:
- Low-E – blocks heat loss in winter
- Low-E2 – blocks heat gain in summer
Cascade Low-E is standard on their dual pane windows. And they offer optional Low-E2 and Low-E3 for enhanced efficiency.
Milgard also has SunCoat or SunCoatMAX Low-E as standard on their dual panes. Low-E can be added to the inner pane of triples.
So both brands recognize the importance of Low-E technology.
- Gas Fills
The space between panes can be filled with argon or krypton gas. This further prevents heat conduction.
Cascade ias argon gas fill available. Milgard injects argon gas into most units as well. This boosts insulation while keeping costs down compared to pricier krypton.
- Spacers
The spacer separates the panes of glass. Advanced spacers like Cascade’s Super Spacer and Milgard’s Edge Spacer improve insulation at the edges.
- UV Protection
Solar radiation can fade furniture and floors. Cascade offers laminated glass options that block 99% of UV rays. Milgard also has coatings to filter UV. This prevents fading and damage.
