Milgard C700 Series
Fiberglass Single Hung Windows
Milgard C700 Series Fiberglass Single-Hung Windows
The Milgard C700 Series single-hung window brings advanced fiberglass construction to a timeless window style. Designed for homeowners who value durability, clean design, and reliable performance, the C700 uses fiberglass frames that are built to handle decades of real-world conditions. Fiberglass is one of the most resilient and energy-efficient frame materials available today. Formed primarily from silica sand, it expands and contracts at nearly the same rate as glass, helping maintain tight seals that reduce drafts and limit long-term stress on caulking and surrounding materials. With its streamlined profile, expanded color palette, and improved thermal performance, the C700 single-hung window offers a premium replacement option well suited for homes across the Pacific Northwest.
Key Features
Built for decades of dependable performance. Fiberglass is one of the most durable window frame materials available, able to withstand years of Pacific Northwest rain, temperature swings, and moisture without swelling, rotting, or warping. Once installed, it requires minimal upkeep and continues performing reliably year after year.
Improved thermal efficiency comes standard. Every C700 window includes Milgard SunCoat® Low-E2 glass and delivers up to 10% better thermal performance than the previous generation. This helps maintain comfortable indoor temperatures while reducing the strain on your heating and cooling systems.
Helps reduce outside noise. Optional laminated glass packages help dampen exterior sound. Homes located near busy roads, flight paths, or active neighborhoods can experience a noticeable improvement in interior quiet once the window is closed.
A style that blends with your home. Six frame color options, coordinated hardware finishes, and a refined modern frame profile allow the C700 to complement a wide range of architectural styles, from traditional Craftsman homes to contemporary designs.
Backed by a trusted warranty. The C700 is protected by Milgard’s Limited Lifetime Warranty for residential homeowners, with the option to upgrade to a Full Lifetime Warranty at the time of purchase, offering added protection for a long-term investment.

Single-Hung Window FAQs
What is the difference between Double-Hung and Single-Hung windows?
Single-hung windows have one movable sash (the bottom), while double-hung windows have two movable sashes (both top and bottom). Double-hung windows offer more ventilation options and are easier to clean from inside, but single-hung windows are more affordable and have fewer moving parts.
Are single-hung windows cheaper than sliding or double-hung windows?
Yes, single-hung windows are generally the most affordable option among operable window styles. They have a simpler mechanism with only one moving sash, which reduces manufacturing and installation costs compared to double-hung or sliding windows.
Is there a difference between single-hung windows and single-sash windows?
The terms are sometimes used interchangeably, but they can differ. A single-hung window has two sashes where only the bottom one moves. A single-sash window technically refers to a window with just one sash panel, which could be a fixed or operable unit.
Should I choose single-hung or casement windows?
It depends on your priorities. Single-hung windows are more traditional in appearance and more affordable. Casement windows provide better ventilation, a tighter seal, and unobstructed views, but cost more. Consider the location, your budget, and desired functionality when choosing.
