thanks Don :cheers:

 

here's a couple pics of the setup I'm dealing with....first one is the neighbor's window on his second floor (thank gawd it's the only window on that side of his house or I think I'd have bigger problems). It faces southwest and catches the afternoon/early evening sun. Second shot is our two houses and the distance between them. My house ® is in full shade on that back corner where the damage is occurring.

yep.....since the problem is happening during the day while I'm at work and can't see it, I'm trying to find some kind of adhesive (cheap) thermometer that records the surface temp over a period of time and records it. Someone on GJ mentioned an aquarium thermometer, but I have no idea what that is. Gotta sharpen my google-fu a bit and do some research.

Hello - Haven't been around for a while & never have been able to offer much - Don't know much about my MJ but I do know a little about glass, including it's reflective properties - Everything offered about your siding from the mfg rep concerning your neighbors house/window is pure BS - Without getting into it in depth that window is P Poor as far as reflectors go - Not all of the suns available energy striking the glass is being reflected and what is has not/will not be amplified - Anyway, has anyone looked at the backside of the siding? What is the siding covering - Plywood - particle/composite - foam? Is the affected area spreading? :???:

This type of nonesense is good fodder for the myth busters show - - Refracted, concerning the electromagnetic energy commonly refered to as light, simply means sent off in a different direction. - - As far as the neighboring widow - - It is certainly reflecting some light as do most objects, black holes being possibly the ultimate light absorbing sponge - Anyway, IF the window glass has the type of coating known as "Low E" it should do a decent job of reflecting both UV and INFRARED light waves - and I suppose that IF the window's glass part is multi-paned with sealed edges AND the ambient barometric pressure allows the outward facing pane of the unit to become concave then certainly there will be a focal point(multiple FPs is more likely) somewhere & not a terribly efficient one either - - - UV and INFRARED are the only light waves, in this case, capable of heat production in any meaningful amount - INFRARED LIGHT IS HEAT - You can feel it, as is, when it bounces off your skin - The neighbors window is simply too far away to give off damaging IR unless THE HOUSE IS on fire & even then it'd have to be a real hot dog cooker - ULTRAVIOLET is another story - an object must absorb UV in order to increase in temperature - So yeah, the siding absorbs UV, but too many IFs & ANDs & just plain BS to blame the neighbors window after 3 years - UNLESS the Maya calendar is right & the Sun has moved into a position so that....... :nuts:

 

HEY - It's five o'clock somewhere :cheers:

nothing coming out of the vent, they are just crawl-space vents (not sure if you're familiar with them ;) )

 

I thought it might be. Vented crawl spaces aren't too normal this far north. Crawl spaces are a bit of a grey area anyways, seems people have a lot of different ideas on venting.

Building codes in the U.S. have required venting for crawl spaces for at least 30 or 40 years.

Yes I know what an F lens is - Do you know what makes it work? - The refractive index of ANY window pane, ground & polished, vertical draw or float process is pretty much ZIP - Dusted off an old E-book & started to run the math on RI for 3mm single strength using PPG Ind standard D for thickness(My confidentiality agreement with them is expired, just in case a lawyer is lurking) & then pretty much realized this is nuts - IT FLAT(get it?) DOESN'T WORK.

 

Still like to know what the siding is covering - Plywood - Structured - Particle - Foam? Especially foam - formaldehyde vapor levels of improperly cured styrofoam sheeting can be high - But after 3 years, 3 months even, Hmmm...

 

Regardless - A vinyl siding tool is 3-4 bucks - A square of replacement viny & 1/2 hour's time max & on to another....

 

 

I saw a peanut stand - heard a rubber band - seen a needle that winked it's eye...... :D

I do know what makes the lens work. If you checked out the video you would see the fire it started. What I see happening is when the sun hits a certain angle the reflection is doubled back from the inside pane, then it comes out through the outside pane on such an angle that it focalizes through the edge of the glass, creating a lens out of the glass at a larger angle of departure. Any expansion or contraction of the thermopane creates even more of a lens than the flat pane.

 

The multilayer creates doubling or more of the refracted light like in the photo question.

The truly SMART window would have a UV proof plastic pane in the center to minimize thermal conductivity unlike the current glass we use.

 

I only know about this stuff from dealing with Solar Tubes and designing a subterranean home that will get natural light and light through reflected lenses. Now If I could only put my minimalist knowledge to use to make the $$ I need to build it.

WOW - previously unmentioned information - Had no idea it had been established that the neighbors window was a multi paned unit; much less coated - _ - _ - Now then, JIC for your development work - The coating must be on the inside pane of the unit for it to have a shot at doing what you describe - Low E windows have the coating on the OUTSIDE pane - Reason is infrared transmission - With hardly any UV being absorbed by the outer pane what little IR is generated must cross a space usually filled with argon gas, or just plain old air in less expensive units to warm the inside of whatever - Just the most basic of engineering - reverse this orientation and the IR radiates straight into the dwelling-obviously not the way to make an insulating window - There WERE some double coated jobs years ago - PPG and LOF both made units of all glass construction - these had glass welded sides, argon filled & were costly - Color/appearance probs associated with the vacuum coating process necessary for the raw glass mandated two coated surfaces, which went away with the licensing of PPGs straight from the furnace(tank) technology - Andersen and Pella were the main customers - Andersen fell under the influence of Cardinal Glass(ASAHI JAPAN) & went to a cheaper aluminum frame with some sort of organic junk sealer & the rest had to follow suit (NOTHING SELLS LIKE CHEAP) - These are, of course, not suited for your use - Use the reflection of something held very close to the glass surface to easily determine coating side - fingernails work great-focus on the cuticle - Sharp image=coated side blurred=uncoated - Fast & dirty & reliable.

 

 

Your ideas of the doubling and redoubling of the refraction coefficient with no outside/additional amplification are intriguing - Should be of great interest to the perpetual motion machine researchers, Flat Earth Society and scientific community in general . . . Good Luck. :yes:

Your code will most likely still allow an unvented crawl space. It just has to be conditioned by the same air system as the rest of the house. That is how I am used to seeing them; makes more sense if it's cold...

That actually has a scientific explanation (I'm looking for the correct link) according to Snell's law.

 

this is a simplified version for now.

http://www.school-for-champions.com/sci ... _snell.htm

 

You appear to be still thinking laws of reflection. Step up to the laser platform and make sure you have your eye protection in place!

 

When light is slowed down, friction results, increasing heat released. In the vacuum between the 2 panes, heat won't release and the inert gas plus the reflective coating will bounce the rays back through the externally reflected rays, increasing their potential, similar to cracking atoms.

 

So who's a flat (pane) earther now? ;)

Fell off the edge again - No, no vacuum - argon or krypton - no vac - Not in the US - :shake:

 

 

 

With apologies to PP&M:

 

Puff the magic window lived on the second floor.

His view was fairly limited to the sky plus the house next door.

 

Little Jacky Turbo loved that rascal Puff;

He'd dream of solar properties and other ilogical stuff.

 

Ohhhh, Puff the magic window...

Wow this thread has taken a couple twists and turns. :D

 

Did you try calling the siding manufacturer?

 

Even if they don't want to warrantee the material, they may have some inside to what is going on.

 

Also, hopefully it gets resolved while that color/ style is still available,

I've heard of people having to reside a whole house because the material wasn't available to replace one section, after a small fire.

(Luckily the insurance company ate that one).

 

Either way, any updates on this?

 

Is there a matching crop circle in your back yard? :D
