Energy Efficient Window Film Vs New Windows – Comparison on Performance

Get a Professional offering you a free estimate for your new windows, and decide if they are or not for you. Decide if you are going to be buying new windows 11 64bit download and when…Please do not let them over price this for you. A Better Quality Window, with life time warranty and the best looking on Vinyl frames retrofit or replacement windows shouldn’t take you to bankruptcy… Here we have analyzed several of the best brands…Ask me. (Can’t publish for obvious reasons) But please do not fall for the cheap ones, nor the one price fits all…you could regret it sooner or later.

Now here is the comparison between energy efficient windows Vs. Energy efficient film, on its performance.

NOTE: – We are departing that none of the above questions in the first section is an issue on your case.

Energy efficient window film

Think on energy efficient window film in situations where you have older, or low-efficiency, but still airtight windows and if you need to increase their energy efficiency without spending a lot of money on new windows. These films cut on radiant heat passing through your windows and also reduce UV radiation entering the home and a little bit the amount of visible spectrum light as well. Help avoid color fading and so much advantages mentioned in this site.

Energy efficient window film is very easy and fast to install: You wouldn’t need a highly trained contractor, so you save money on the installation as well. (Find the link with instructions at the bottom of this article)

Of course, energy efficient window film doesn’t block out all infrared radiation, but it does get most of it: rejecting 99% of the UV radiation reducing fading and the risk of skin cancer.. And it provides close to the same level of energy efficiency as buying new windows with low-E coatings, assuming you are not in the situations listed above.

Energy efficient window film, can block up to 38% of the heat loss that normally escapes through your windows in winter, and up to 70% of the solar energy that normally enters through the windows in summer.

In addition to the energy saving benefits, solar window film can increase thermal comfort and reduce glare.

If you came finding technical information, here are some amazing numbers about the efficiency offered by some of the best of these films:

  • Total Solar Energy Rejected more than 70%
  • UV Light Rejected Almost 100%
  • Glare Reduction more than 80%
  • Visible Light Reflected Exterior more than 40%
  • Solar Heat Reduction almost 70%

Energy efficient Double Pane windows (Replacement vinyl framed windows)

Obviously there is no comparison on the performance of these extremely high technology products. And is not due to the dual glass panes compared against the single pane windows, And not only the multilayered films that come in both of the panes of these windows, but in top of that now they come with Argon gas filling between the glass panes, (Argon is a harmless gas, very dense and bad conductor of heat, always present on the air we breath all the time; so is not scary.)

The sophisticated and technologically advanced material used in the construction of the frames of these windows, together with the very unique design of the vinyl frame profiles, the quality of the new technology applied to gaskets and seals, spacers, etc. There is no match on the efficiency obtained. These new windows may save up to 40% of your utility bill under certain conditions.

You will need a responsible and reputable professional advise to learn about your possible savings. It all depends on where you live and how do you live. He will know with a few questions if new windows will reach this goal. Get additional info here at the bottom of the article.

Without entering on deep technical data (Which can be found at ) here will mentioned that an Energy Star rated window MUST be efficient enough, to be airtight, and its glass panes, most be constructed in a manner that reflect sun, heat and UV Rays. So you will not need that much energy to be comfy at home: > WARNING: So many people states that they almost never use their HVAC but KEEP fans and ceiling fans running 24/7 Be careful, these are smallest and less efficient systems to cool your home…rather than your HVAC, and this energy is not free!)

Energy efficient windows are Rated by mainly these factors:

U-Rate or U-factor. Means coefficient of heat transmission, a measure of the rate of non-solar heat loss or gain through a material or assembly. U-values gauge how well a material allows heat to pass through. U-value ratings generally fall between 0.20 and 1.20. The lower the U-value, the greater a product’s resistance to heat flow and the better its insulating value. The inverse of (one divided by) the U-value is R-value

R-value is simply how resistant a material (A window in this case) is to avoid the pass og the heat through.

Solar Heat Gain Coefficient (SHGC)

Putting simple words these measure how much heat your room gains from solar radiation admitted through a window, either directly transmitted and absorbed and subsequently released inward. It rates between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits. Inside your building.

Visible Transmittance (VT)

This measure the visible light from the sun in your room. Measure varies between 0 and 1, most values among double and triple pane windows are between 0.30 and 0.70. It is not known to have a whole 1 in this factor, would be like having 100% and is not likely to happen. However, the more light is transmitted, the better, this is desirable to maximize daylight; so you don/t have to use electric light during the day.

Air Leakage (AL)

Heat loss and gain occur by interchange of air from inside/outside of your home. Infiltration through cracks in the window’s assembly. These rating (AL) is measured by cubic feet of air passing through a square foot of window area in a given time. Airtight is never 100% on movable windows. New windows should have rates of 0.30 or less (cfm/sq ft=cubic feet per minute, per square foot of window). Just know that high quality windows tend to be way higher than these standards, in each sense, your investment will pay.

Not considering the enhance, the comfort and curb appeal, your new windows are maybe the best upgrade you can make to the exterior on your home. Consider that, aluminum framed windows just like the single pane windows; are something you will need to replace today or in the feature.


Energy efficient window films will be a temporary solution in most cases. Still if you are in a budget and have nice and sound windows; you may add a quality energy efficient film and protect your home while saving energy. No doubt. Even on older windows, you will improve the performance.

Energy efficient vinyl windows now are available in colors and textures even wood-like; to satisfy the most picky people. And of course, there are windows made out of real wood, beautiful and efficient; you pay a more and they need maintenance, but it may worth.
