Why would anyone ever want a 5 mm thick thermal pad?

This question is only tangentially-related to overclocking but there is no more suitable subforum. I would like to know why there is a seller of silicon pads in multiple thicknesses up to 5 mm? Why would anyone ever want such a thick pad when it's probably the main bottleneck in heat transfer?

(I'm not considering thermal pads for a CPU but rather a lighting project).
 
Solution
To expand on above post ... some components use chipsets of varying height, but are cooled with a single heatsink with flat surface. Thicker pad may be needed to fill larger gaps. Have experienced this very thing on several graphics cards where GPU is taller than memory chips.
