What Is a Replacement Window?

So, replacement windows are not a one-for-one, exact replacement.

Replacement windows are sometimes called pocket windows or insert windows to reflect this.

Replacement vs. New-Construction Window

Replacement windows might seem like the only solution for your needs.

Replacement windows do not have any fins.

When the house gets too hot, you unlatch the window and slide the lower sash up.

But with single-hung windows, the upper sash is fixed in place and inoperable.

Only the lower sashslides up and down.

With double-hung windows, both sashes can move.

This is especially valuable for upper-story windows because it allows you to clean windows from the inside.

If neither conditions apply to your home there is little reason to buy double-hung windows.

You will save some money with the single-hung windows.

Plus, with fewer moving parts, the single-hung windows have less of a chance of failure.

Fixing vs.

In some cases, this may be premature and a waste of money.

Instead, you may need to fix a failed window seal.

One indication that the glass has failed is fogging on the inside, between the panes of glass.

In this case, it is possible torepair the windowor replace the window sash.

That’s because caulking may not set all that well in very cold conditions.

Moisture from inclement weather may also affect the tight tolerances needed for window installation.

Windows and walls both have R-values, which is the standard by which energy loss is measured.

You’ll come across R-values when shopping for windows.

When it comes to a window, anything above an R-value of 2 is considered good.

Here’s how single, double, and triple-pane windows stack up to help you choose.

You may also come across a window’s U-value.

For a replacement window, look for a low U-value and a high R-value rating.

The lower the U-value number the less the window will transfer heat.

Single-Pane

A single-pane window has an approximate R-value of 1, which does not offer much insulation.

A double-pane window can increase your energy efficiency by almost 100 percent.

Double-pane windows are standard, even in parts of the country that have temperate climates.

For extreme climates, consider purchasing triple-pane windows.
