Replacement Vs. New Construction Windows

Which one is appropriate for your project? Here’s the run-down:

New Construction:

This type of window is for brand new homes, or for occasions when the window replacement window will be larger or smaller than the original. New construction windows come equipped with nailing flanges for mounting.


For projects where the new window fits inside, the replacement uses the same dimensions as the original, requiring no structural change to the house. These do not come with mounting hardware, because the new window is installed inside the existing wood trim and frame.

Energy-Saving Terminology

What do all those acronyms mean, anyway? Here are a few to watch for:
Rates the amount of heat allowed through the glass pane and frame in either direction. The lower the number, the better the insulation.

Term for a single sheet of glass. New windows are double- or triple-paned for added insulation.

Low-E (low emissivity):
Glass coating that lets in light, but blocks both heat and ultra-violet light. Protects upholstery, carpet, and interior finishes from fading or sun damage.

Solar Heat Gain Coefficient (SHGC):
Measures how much energy from the sun passes through the window. The lower the number, the less heat allowed through the glass.

A gas sandwiched between double- or triple-paned windows to increase insulative properties.
