I know that the black, high temperature tiles are coated with black borosilicate, but are the white low temperature tiles also coated with someting or do they just consist of LI-900?
Thank you very much
Please apologize my bad English ;)

Quoting Jenkins:
"...and [the LRSI, ie. white tiles] have a white optical and moisture-resistant coating applied 10 mils thick to the top and sides."
They are also waterproofed, but that's not exactly a coating per se.

Does anybody know where I can find detailed information about Space Shuttle TPS?
How many of the tiles where replaced after flight?
How they were protected from micrometeorites damage?
Why tiles are made so small?
Why tiles are unique? (I understand why they use tiles made of different materials at different parts of the orbier, but why all tiles where unique? It is possible to make almost any surface from for example triangles)
What is used to fill the space between tiles?
Haven't found enough data in Google :(

A good start is the Jenkins book previously quoted.
Space Shuttle: The History of the National Space Transportation System The First 100 Missions, 3rd Edition by Dennis R. Jenkins. About $25 on Amazon.

it varies
They are thick enough to survive MMOD damage
Because the orbiters body flexes and larger tiles would then crack.
It is the bottom of the tiles that is unique. They have to fit to the contour of the vehicle.
