Tinted Windows

[Guest tony b]

Guys i was wondering if anyone could reccommend someone or somewhere to get my windows tinted, and also has anyone had it done and been pleased with the results (live in East London) :unsure: :unsure: :unsure:

Thanks guys n gals B) :D

I had mine done earlier this month as I have no aircon, typically it hasn't been sunny since.

 

The job was well done, the only downside is the glue they use has problems sticking around bits of the 2 rear windows and the back window as they have the black gradiated dots on the surround of them, I managed to get it looking a bit better by running my finger over the film to push it more firmly onto the little dots, it doesn't look too bad at all now, noticeable but not glaringly obvious.

 

The important thing is that it keeps the effects of the sun at bay, as soon as we get some sun up north I'll let you know how successful it has been.

 

I think they used Lumar film at the place I had it done.

 

I had all the windows done, lightest tint on the two fronts and the second darkest available on the rear five and a sun strip on the windscreen, they even did the little quarterlights in the front A pillars.

 

Cost me

[Guest tony b]

cheers mate where did you get yours done?? I only want the back half done

[burundi]

It's a bit out of your way I'm afraid, Tintmaster in Preston, Lancs.

 

I don't know what prices will be like down in the big smoke but mine cost about

[cos 4x4]

:23: had mine done down here in south wales by a firm in caerphilly cost 200 for the full car darktints to the back 5 and very light tints to the front doors and small quarters and a dark top tint to the windscreen

obviuosly the front is illegal but the guy says if you get caught they where on the car when you bought it so no come backs to him and its a tidy job

[Guest Jambo25]

Try this company in sutton they are very good and come highly recommended as I've used them over the past few years on several cars! Auto Shades :P

 

:P-->

Why doesn't the normal physics apply here?

I thought black things absorbed all light and reflected nothing to give it the "black" look.

So surely, as you're attracting all the light, your car will heat up even more!

It is the ultraviolet that makes your skin feel hot when the sun hits it. The black film blocks all the UV making it feel cooler.

ehhh No its infra-red which warms up the skin, ultraviolet stimulates the production of melanin e.g tanning. Ultra-violet photons have enough energy to knock electrons out of atoms - thus doing chemistry, photons of visible light can in some circumstances do the same (usually in semi-conductors with small band gap energies) but in the human skin they and infra-red photons knock the electrons around and make the atoms vibrate more - raising the temperature

surprisingly enough :10: the boring old normal laws of physics do apply :D :D darker objects absorb more but they also radiate more

wow this carpark's dark there must be a blacked out car in here -_-

this is what the ancient greeks believed for a while :D

they absorb the light - warm up slightly and re-radiate as infra-red (ps which we can't see so it looks dark)

Way to go teach!!!When does the lesson finish??wanna apple???? :10: -_- :D :D

when they believe it :D :D

[mumof4]

So why does the heat stay in the car and not dissapate???? :10:

[NikpV]

it does but air is a poor conductor, for the air in the car to get cooler it must move by convection to cooler parts and lose some energy - without forced convection(fan blowing) it will rise to the roof because its less dense - if the roof is not cooler the air gets hotter and hotter until the skin of the car in contact with the hot air gets hotter and radiates more and more. the roof is cooler then the air will transfer some energy by conduction, become more dense and sink again, the roof may lose this extra energy by radiation or it may be carried away by moving air in contact with the roof.

 

The movement of heat (thermal energy) is controlled by the interaction of conductoin, convection and radiation all forced by temperature differences.

As in light is energy and energy can not be destroyed so it has to go somewhere.

 

I knew about the black re-radiating though, I still remember the cube lesson at physics......

 

All household radiators would be matt black if we wanted them to really work!

household radiators transfer most of their energy as convection - they are misnamed, in our old science department we painted all of our radiators matt black to emphasise the point

stefan-wein law IIRC - not taught it for years :D frequency of emitted radiation depends on the cube of the temperature ? things need to be 1000K (700-800C) to emit much visible light :( :D

[Bigjeeze]

So is it a dark or light tint you're going for? :(

[Guest tony b]

:43: Thanks guys only wanted to know so i can keep my work tools in the back of my gal!! lol But all very interesting anyway :unsure:

Dark tint so i can hide my work tools. Only want back quarter done :o

[Masked Marauder]

Has to be silver then!
