My inside screens went through hurricane Wilma with 75 + MPH winds with very little movement.
Other then when she shook the whole MH some.
They were dry & clean after over 9 hours of steady wind with no let up.

Just for the sake of asking:
Is there any company making sun shades with a material similar to the stuff that is put on house windows to keep the UV out (and not see through from the outside) but you can still see through from the inside ?

We made our own based on the Magna Shade idea. Their quote was over $700 for windshield, driver and passenger side windows. We purchased the material at Phoenix Tent and Awning, bought the magnets online, and double backed tape at Ace Hardware. DW and I made the patterns and she sewed it all up in 1 day. Total cost was $254. Loved their idea and ease of use, just not their prices. This was a fun project and a savings of over $400. DW is really good with a sewing machine.

I believe that it is all the same material. You can see from dark to light to during the day no one can see in but you can see out clearly. At night everyone can see in but your view is obstructed.

There are materials available in many degrees of protection even to total blackout from most all sunscreen manufacturers. The material we chose is 95% blockout and see through from the inside.The advantage of exterior type installation is that heat is not conducted to the interior as readily. Really helps the ac in the summer. Interior installation allows the glass to be heated and transfer to the interior of the coach. Its amazing how much heat comes through that big windshield. We started out with the interior type but soon changed to exterior and wont go back. Magna Shade has the easiest installation of any we have seen, and no ladder needed, just a long stick to push them in place. Wheather you build them yourself or purshase from Magna Shade I think you will be well pleased.

Tnx Bill and AZ:
This is not quite the stuff I was thinking of , I was referring to the plastic type material that is applied to the inside of home / business windows that is used to reflect uv and direct sun light, was just hoping someone had come up with a variety that could be un folded and snapped on to the outside of the MH windows.
Not really too concerned with someone seeing in at night (unless they get a heart-attack from laughing too hard) just don't want to over heat the glass too much and have it crack .
Tnx & 73, John

From the Magne Shade web site:

"....We use Phifertex plus exterior sun block fabric, this is a woven polyester pvc coated material that will outlast fiberglass or other screen materials. This fabric blocks 90% of the solar energy that is entering your windshield....."

We have the Magne Shade screens. They are a breeze to put up. Less than 30 seconds for the front windshield, usually 15-20 seconds, and a lot less for the side windows. It takes longer to pull them out of the storage bag than it does to install them. Check out the web site for a video and other options.

Shades

We purchased a MagneShade and it really looks good and compliments the color of the coach. Very easy to install or take off. Would buy this shade again.

Myth on outside shades being cooler busted.

Tests have shown that when a heat indicator was used to compare Shades mounted on the inside to a shade mounted on the outside( made with the same density), the temperature measured 18" back from the windshield proved nearly identical, with the inside shade actually being one degree cooler.

Both shades inside or out, are designed to give you daytime privacy and reduce the UV and heat in your coach.

Its not the temp of the shade that matters, its the heat load added to the interior air. Placing the shade on the interior allows the solar heat energy through the glass and hits the shade. It does not exit but is added as heat to the air between the shade and the glass (hot house effect) That heat is added to the interior air space and must be removed by the AC system. The exterior shades never allow the energy to go through the glass. Its simple physics. The exterior and interior shades may reflect the same amount of light but the net heat gain is far different between the two. This is why solar shades on outside of windows on homes are far more effective than dark drapes on windows in keeping heat load out of homes.

Any 'test' that shows otherwise is flawed in what is measured or implying things not acutally measured.

Just touch the inside of a windshield with interior shades and then do the same with exterior mounted shades. If the windshield is hot to the touch then the heat is already inside the coach and that's the fact. No inside windshield screen is going to make that heat go back out again. The outside shades keep the windshield substantially cooler which keeps the interior cooler as well.

Thats called common sense here in Texas don't need a Pork Barrell study!

No argument there Bill -- however, we've had both and prefer the inside shade due to ease of installation and the shade stays dry/clean. Takes less than 5-minutes to install/remove. Sort of like the choice between Ford or Chevy in the 'old days' -- each has their pluses and minuses.

I recently did some tests at MCD MCD Innovations regarding inside versus outside. Surprisingly both offered similar protection against heat intrusion while the interior MCD shade offered improvements in cool weather heat retentsion. I ran a dual probe digital thermometer and sampled the heat on both sides of the inside sun screen and found a marked difference. I also found out why black sunscreen (which absorbs heat) was a better choice than white (which reflects heat). The "white is better than black" idea holds true for a solid material, which makes sense, but it's just the opposite for a mesh. The white mesh allows the energy to bunce off the round threaded mesh and passes the solar energy through the mesh. With the black mesh it doesn't pass through. The interior screen holds the heat back and reflects it back towards the windshield. Temperature readings on the windshield side of the sun screen were substantially higher than the inside of the sunscreen. The actual amount varied by how much sun was coming in through the windshield. The exterior shades don't have that "heat trap" in front of the shade but the mesh gets hot and conducts that heat to the windshield glass because it's laying on it and that heat does radiate into the coach. So, in the end both the interior and exterior shades work. It's just that it's easier to push a button on the interior shades to deploy or store them rather than go outside in whatever weather to deal with them and then roll them up and store them (hopefully they aren't wet at the time).

MCD makes both inside and outside versions. After looking at their sunscreenthrough a magnifying scope and comparing it to other screens I have to say that they really do have an excellent product. I did detail ny coach installation at MCD Shades - Index if anyone wants more information.
