Window Replacement vs. Retrofit

Summer is here and buildings with outdated single-pane windows are heating up like a greenhouse.  To replace or not to replace? That is the question.

However, window replacement is costly in both time and money. If you are a building manager this will disrupt the work environment of your tenants. If you are a homeowner, finding the perfect time and weather to completely change out all the windows in your home is extremely difficult. And how do you measure the typical payback? Most experts agree it takes 15-20 years to see a return on your investment for window replacement. Let’s examine a few alternatives that aren’t as hard on your schedule or your wallet.

To avoid window replacement without losing money out the window, you can apply a solar film that reduces heat while protecting inhabitants and furnishings from harmful UVA rays.

Commercial window films also encourage more consistent temperature flow throughout the building. Solar / low-e window film can be applied to the interior of your windows by a professional and is backed by a manufacturer’s warranty.
