Is it Accurate?

Accuracy counts… in some things.

-“He missed by a mile!

-“We were close…”

-“Looks good to me…

These expressions are one thing when stated by your sports caster or weatherman but quite another if you heard your accountant or surgeon make such statements. Accuracy is important, even vital in some instances.

The window film industry has suffered from inaccuracy, inflated paybacks, unfounded statistics, and misapplied specifications among many other things. For instance, how many times has someone misapplied single pane 1/8th inch glass specifications saying that a 15%vlt window film will block 80% of the total solar energy when the window that is being considered is dual pane? If you did then you certainly missed this one by a mile for the total solar energy rejected on insulated clear glass is closer to 71% not 80%! “Well, we were close” you may say… Hardly! What if this was a 40,000 sq foot project? The results would be different, one would be accurate and the other would be inaccurate.

This scenario can create a chain reaction of misinformation such as an inflated payback or ROI (return on investment). Statistical data becomes inaccurate when we do not take the time to generate factual data. We then have a problem because once someone discovers that we have taken liberties with specifications it erodes our credibility as a whole. It is much more beneficial to not only bring accurate data to the table so to say, but to also be able to verify that the data is accurate and explain why that is so.

For years now the window film industry has measured most of their published specifications on 1/8″ clear single pane glass. We blogged why this was the common practice and the reasoning and benefit behind it. There was always a need for a standardized specification and standardized testing that could be verified by a neutral 3rd party to be both accurate and at the same time recognized by agencies such as the Department of Energy (DOE). This was a crucial step in leaving old practices behind and moving a head in the promotion of accuracy. It was also vital so that single-region measurements would not be mismarketed to the general public and misinterpreted as total solar performance data.

A landmark occasion has arrived for the window film industry. There is a neutral 3rd party organization to certify window film performance specifications not just on single pane glass but on dual pane glass as well. The National Fenestration Ratings Council (NFRC) is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, attachment, and applied window film products. Currently, there are two window film manufacturers with certified products listed in the NFRC Applied Films Directory. This accurate data can be used to not only compare the total performance of one film to the next, but it can also be used to calculate the glass’ affect on building performance and the return on investing in window film.

We have come a long way from presenting our customers with a specification card that in most instances does not apply to their glass situation and yields an inaccurate result. NFRC Certified Films are now recognized by the DOE as an energy saving device and in time, will qualify to be rated as Energy Star products. Consumers can rest assured that they are being given the most accurate and relevant data to date so the they can be confident in their buying decision.
