Title: Window Film
Post by: 64avanti on June 23, 2011, 02:43:41 AM
It has been stated that window tint is not safety film.  So what film is considered acceptable?

There is a clear film we use down here in Florida to cover windows to reduce the amount of glass flying in Hurricanes. It comes in a few different Mil thicknesses. I was going that route but just decided to replace with Lexan this year. I can ask our window tint guy at the dealership and let you know. He knew exactly what I was talking about when I asked him. On the upside it has some UV blocking characteristics too. Which might prove to be a good thing at Bonneville.

My problem is this: If they say that it needs to be "safety film" then it needs to be defined by SCTA.  In other words what product is acceptable.

Last year most of us had tint film and that was accepted.

Most places that do home or business security handle a clear window film that is designed so that the bad guys have a much more difficult time breaking through windows. You might want to try that.

There is no defined  film product by the SCTA because the none passed the tests. This is why the rules have been changed to plastic windows.

Search previous threads for options such as the motorhome stuff suggested by Brian last year.

From the Rules Correction link at www.scta-bni.org

3.U WINDOWS AND WINDSHIELDS:
All non-stock windows and windshields shall be made of shatter-resistant plastic, such as polycarbonate (Lexan), and
shall provide 120 degrees of adequate vision forward. On all open body cars a windshield is recommended, but shall not
restrict driver entrance or exit. In all classes where a headrest fairing is permitted, the windshield may sweep around the
driver’s head and connect to the fairing on either side (see 3.E Driver’s Compartment rule concerning sharp edges).
All windshield wiper blades and arms shall be removed. On front and rear windows, retaining tabs or straps are required
over 175 MPH.
Vehicles with T-Tops or moon roof panels shall have the panels retained with tabs or straps.
All vehicles over 250 MPH shall replace all non-laminated safety glass windows with polycarbonate
material. All other glass, such as headlights, must be covered with SAFETY film.
Beginning January 1, 2012 all vehicles in classes where the record exceeds 200 MPH must have all nonlaminated
safety glass windows replaced with polycarbonate material.
Beginning January 1, 2012 all vehicles with “frameless” side windows, regardless of speed, must have all
non-laminated windows constructed of polycarbonate material.
Additional bracing must be installed to prevent window blowout or collapse.
Added from 2010 rulebook, in effect for 2011:
All Vehicles shall have all non-laminated safety glass windows with safety film ON BOTH SIDES, or replace
the windows with polycarbonate material.

Now, Based on what Dan said above, there isn't any SCTA approved Safety Film.
Therefore If it isn't Polycarbonate or Laminated Safety Glass, you don't run at El Mirage or Bonneville. Makes it simpler actually.
BUT!
What do we do about the Headlights? I'm not being facetious, in some of the Classes you have to have headlights, no decals allowed.
Headlights have to have Safety Film.
There isn't an approved Safety Film. we have a conundrum.

Last year went through inspection with window tint film like everyone else.  The rules are the same for this year.  So now what?  SCTA needs to define what they will accept for this year. 

Many but not all of the products sold as safety film are no different than the tint film.

   If you passed tech last year with tint film on both sides, it will be OK this year. Next year, All bets are off. Polycarbonate will solve the problem, and answer the questions. I wouldn't try to go through tech next year with anything less.

Maybe it's late and I can't read but what I think I read was

Beginning Jan 1, 2012  cars in classes with records over... 200  all "non laminated safety glass" must be replaced with polycarbonate /Lexan,,,,

Does this mean if your car has a "laminated safety glass" windshield or back glass they will be Ok ?

yes Charles, that's right. It's the safety glass that shatters into little 1/4 inch balls that is hated.

It's the non-laminated, tempered "safety" glass that breaks into the 1/4 inch balls instead of sharp shards.
Laminated "safety" glass is two sheets of glass with plastic in between. It can shatter and still hold together as a sheet. Remember the accidents you have seen where someones head went into the windshield.
Need to check carefully to see what you have. I know as far back as 58, Chevys had single pane tempered rear glass.
If you don't know what you have, you might go to a glass shop that has replacement windows for your vehicle. The laminated glass is obvious, looking at it from the edge, you can see two separate sheets of glass bonded together.
YMMV roadsters don't got no stinkin winders

"If you passed tech last year with tint film on both sides, it will be OK this year."

This statement has been made more than once during all the discussion on the issue. It is also a true statement. If in doubt use section 16 of your rulebook and call someone who is either tech or your car type committee. Thats what the section is there for.

Ok, we have thick clear film on the outside of our side and rear glass in the production car.  We have window tint on the inside of these same five windows.  DW, are we clear for take off or do we need to have the "safety film" on the inside also?  This has really been a headache for us to get a straight answer and we are getting close to time to load up and head west.

I emailed both Mike and Steve and Mike responded to me last night.  I had asked about our car passing tech with the same setup we had last year which is a flim that most put on the frontends to protect against rock chips and then a tint on the inside.  This is his response.  "Yes, you are good with the same laminate configuration that you had last year! The rule was approved before all the testing was completed and unfortunately it showed that no matter what material was used, the glass still shattered and made a mess.  I will push to amend the rule next year to allow window tenting along with safety film like you are using."

Mike Manghelli SCTA Rules Coordinator

Thanks Mike.

Just passing on the info for anyone that can benefit from it.
