Are you looking to change your windows?
Well, before you bite the bullet, you should first check if your windows need changing in the first place.
If you’re unclear of how much life your windows have left in them, then it's time to do a checkup. Some signs can help you determine if your windows are worth saving and holding on for a few more years.
How long do windows typically last?
There is no definitive answer to this question and it depends on the lifespan of the glass more than it does on the strength of the frame. Modern windows usually last up to 30 years with varying levels of maintenance requirements.
So if you're wondering how to test your current window, there are some practical steps you can take to test your windows and decide the best course of action moving forward.
Why Testing Your Windows Matters
Windows play a key role in the overall structural health of a home, the level of comfort, and energy efficiency. Yet, windows can lose their luster over time (frames shift, glass coating degrades, etc.). Small, unnoticeable issues will then start driving your energy bills up and create draft, which causes additional problems for the inhabitants.
Testing your windows can help you identify issues early and make an informed decision on maintenance, upgrades, or professional solutions such as insulating window films.
Common Signs Your Windows May Be Underperforming
The easiest way to check if your windows are still fulfilling their role properly doesn’t require any tools.
The easiest way to go about it is to feel for a draft around the window frame or look for condensation between window panes. The latter indicates that the seals are failing.
Additionally, look for visible cracks, gaps, or peeling caulking around the frame. If you have thermostats across rooms, check for uneven temperatures, and finally, check if your energy bill has increased without a clear explanation.
What To Look For
If you’re looking to test window efficiency, below is a non-exhaustive list of things you should look for.
Difficult to Operate
A working window should be easy to operate. If you notice your windows are getting difficult to open and/or close, perhaps it's time to change them.
Draft and Low Energy Efficiency
When you’re performing a window heat loss evaluation, signs of drafts, especially in winter, is usually the big telltale sign that something is wrong. Homeowners should also check the level, plumb, and bowing to determine whether their windows were installed properly.
Outdoor Noise
There are no fully soundproof windows; however, glass thickness coupled with insulating window frames can help in keeping noise levels to a minimum. If you’re noticing an increase in noise pollution inside your home, that can also be a sign that the windows are fading.
Damage
Obviously, any damage to the window can cause structural issues, but besides the obvious physical damage, there could also be underlying, almost invisible issues that could lead to damage over time. Water damage, mold, condensation, cracks, or chips can often go unnoticed when performing a window insulation check.
Enhance Window Efficiency Without Full Replacement
In some cases, window replacement may not be the best course of action. After performing the window heat loss evaluation and the window performance test, you’ll have a solid understanding if you should improve the integrity of your windows or simply replace them.
Hopefully, you can still squeeze a few years from your years, as replacement is a major investment that requires more time to complete.
The best upgrade is the thermal regulation window film, which is designed to enhance the current windows by improving indoor comfort and energy efficiency without the disruption a full window replacement would require. Most high-quality window film can be done as a DIY project, but getting professionals involved guarantees a flawless and quick installation.
By installing high-quality window film, you can immediately enjoy:
- Lower heat gain in summer, and heat loss during winter
- 99% less harmful UV rays, which preserves furniture, flooring, and fabrics
- Stronger glass, since window film adds a layer of safety over your current window glazing
- Lower energy costs due to better-regulated indoor temperature
As a plus, window films can also reduce visible light transmission, which can drastically boost the visual comfort of your indoor spaces.
Conclusion
Testing your windows is straightforward and inexpensive,and can provide you with a better idea of your home’s overall energy efficiency. If you notice signs of wear or underperformance, there are steps to take before replacing your current windows.
Adding high-quality window film can solve most, if not all, issues. Discover how simple upgrades can transform your windows’ efficiency and keep your spaces comfortable all year round. Explore Solar Screen’s wide-selection of window films.
