Do I Need New Windows or Doors?

The lifespan of your windows depends on various factors, including the frame materials, installation quality, and your local climate. But how can you tell when it's time to replace them?

Moisture Issues

If you've noticed water between glass panes, leaks, water stains, or signs of wood rot, it could be a sign your windows need replacing. Excess moisture around your windows can lead to mold, mildew, and warping, causing long-term damage if not addressed.

Energy Efficiency 

If your energy bills are rising or if you need to wrap up in a blanket to sit by your windows, it may be time to upgrade to energy efficient windows.

Noticeable Wear & Tear 

Cracked or rotting frames, peeling paint, and warped window sashes are signs that your windows are no longer performing properly. These issues can affect both the functionality and the aesthetics and safety of your home.

Hard to Operate

Windows that are hard to open, close, or lock can be both frustrating and unsafe. Modern windows offer user-friendly features such as easy-to-use locks, smooth operation, and even motorized options.

Why Fiberglass?

When replacing your windows, give careful consideration to the framing material. Infinity from Marvin uses Ultrex fiberglass for proven, long-lasting performance.

Ultrex vs. Vinyl

Ultrex is 8x stronger than vinyl, which means you get narrow frames that brighten your home with more daylight and bigger views compared to vinyl. Additionally, vinyl can warp and shift over time, making windows difficult to operate and affecting their overall performance. Ultrex resists sticking, swelling, and warping, ensuring that Infinity windows remain easy to open and close.

Ultrex vs. Wood

Wood windows provide classic beauty but often require ongoing maintenance depending on the environment, as well as potential rot issues. Infinity windows offer the same beautiful details and profiles of wood—without the upkeep. Additionally, although Infinity windows do not require any painting, they can be painted any color or stained on the interior.

Ultrex vs. Other Composites

The Ultrex fiberglass frame is highly stable, expanding at nearly the same rate as the glass. In contrast, vinyl and wood/vinyl composites expand over twice as much as glass, which can affect energy efficiency and performance. Ultrex is also 3x stronger than wood/vinyl composites.

Installation Options

Insert and full-frame fiberglass window replacements

At North Georgia Replacement Windows, we offer both insert and full-frame replacement options. Insert replacement is a method used if your window style isn't changing and the existing wood frames are in good condition. Full frame replacement is a method used to update unstable vinyl or aluminum windows, change the window style, or if the existing jambs are damaged.

Common Terminology in Windows & Doors

Balances - A mechanism inside a window that helps control the movement and position of the window sash (the part of the window that holds the glass). It makes it easier to raise, lower, or hold the window open. This mechanism ensures that the window stays in place when opened and helps prevent it from slamming shut.

Brick Mould - Frames the outside of the window, acting as the trim that borders the brick or siding material.

Casement Window - A side-hinged window with crank-out hardware that swings outward from the left or right for improved ventilation.

Daylight Opening (DLO) - The width and the height of the visible glass.

Double Hung Window - Double hung windows feature two movable sashes (top and bottom) that are mounted in the window frame, allowing them to slide and operate vertically for improved ventilation and easy cleaning.

Frame - The stationary portion of a window that encloses either the glass (direct glaze) or the sash (operating or stationary) and consists of the header across the top, the side jambs on the left and right, and the sill across the bottom.

Grills Between Glass (GBG) - Dividers installed between two panes of glass providing the decorative benefit of true divided lite grids. GBGs are easier to clean than traditional grills due to not having any bars on the outside of the glass.

Jamb - The vertical sides of the window frame that hold the window sash in place. It's the part of the frame that you see when you open or close the window, and it supports the entire window structure.

Low-E Glass - A thin layer of low emissivity (Low-E) metallic coating is applied to the glass pane to enhance energy efficiency by reducing heat transfer and blocking harmful UV rays.

Simulated Divided Lite (SDL) - Fixed grids placed on the surface of a window to mimic the appearance of traditional divided windowpanes, offering a classic look without the need for separate glass panes.

Spacer Bar - A strip of material that separates and supports the panes of glass in a window to maintain the space between panes for increased thermal insulation. Spacer bars are used in double and triple glazed windows.
