Looking at Storm Windows vs. Replacement Windows

When upgrading their windows, many homeowners wrestle with whether to go with storm windows vs. replacement windows. Storm windows are glass or plastic pane window units that attach to the existing window frame on the exterior or interior of the home in order to protect existing windows as well as supplement their insulation. Replacement windows involve a more permanent solution to drafty windows, in which the entire window unit or at least the glass of that unit are completely replaced. Here are some of the advantages and disadvantages of replacement windows and their storm window counterparts.

Benefits of Storm Windows

One of the main reasons why homeowners choose to invest in storm windows vs. replacement windows is cost. Replacement windows must be cut to fit existing window spaces and then installed. In addition, they are made from more expensive, higher quality materials, as they must be strong enough to protect the home on their own. On the other hand, storm windows are meant to be used in conjunction with existing windows and thus can be made of cheaper materials. Yet they're still able to greatly decrease drafts and address other insulation issues associated with old, leaky windows. In addition, depending on the model you get, storm windows can offer other benefits normally associated with replacement windows, including improved sound resistance, decreased window condensation, and reduced damage to interior fabrics from UV rays.

Interior storm windows also provide an excellent alternative in cases where the exterior appearance of the building must be preserved. This is particularly important for homes where there is a large emphasis on their historic or vintage nature, as interior windows can be installed to boost insulation without disturbing the home’s outward appearance. Exterior windows are also handy for delicate stained glass windows, as they can be installed to protect them from the elements during the winter months.

Advantages of Investing in Replacement Windows

Most experts recommend that if homeowners are considering storm windows vs. replacement windows and they have the means to do so, then it’s best to invest in the more expensive replacement window option. In terms of energy savings, replacement windows are generally much more efficient than their storm counterparts, particularly if they are certified as Energy Star by the U.S. Department of Energy. Replacement windows are also considered to be a long-term investment, which means that they are designed to last longer and operate longer at a higher level of efficiency than storm windows, which can positively impact home resale value and salability.

Drafty windows can end up costing a homeowner hundreds of dollars each year in expensive utility bills, making remodeling windows a priority. In contemplating storm windows vs. replacement windows, homeowners need to consider cost, but also issues of window quality, curbside appeal, and home value.
