I can confirm that my single nozzle board works fine with BuildTak. I have noticed though that the trigger hight might not be exactly the same with my kapton covered bed.

While I don't know what the case is with the BuildTak material, it is worth bearing in mind that colours that look dark or even jet-black under visible light may reflect IR well.

While I don't know what the case is with the BuildTak material, it is worth bearing in mind that colours that look dark or even jet-black under visible light may reflect IR well. I once had a monochrome camera that automatically switched to IR below a certain visible light level, and I recall seeing black clothing magically changing to white as the IR function cut in - it looked very strange because nothing else in the image changed appreciably. The camera could also see through black Perspex as if it were 100% clear. The Perspex was so opaque that you could look directly at the Sun through it quite comfortably, which brought home the point that using such ad-hoc material to view the Sun (or welding arcs) is dangerous as your retina would be hit with the full amount of the Sun's IR output without you realising it, which I should think would cause a lot of damage in a pretty short time.

Black objects are generally good emitters of IR as well as great absorbers, so you are not only seeing reflected IR, but emitted IR produced after absorbance of IR and other wavelengths. (as far as I know ;-) )
