How heavy are these 10mm thick boards

Very light it’s only a dense polystyrene And they are only 1200 x 600mm. I found a paint scraper best for trimming them rather than a Stanley knife.

Want to use under vinyl click in garage with lumpy floor would this work?

I used it on a concrete floor which was slightly uneven prior to laying down ceramic floor tiles, my suggestion would be to even out any big/excessive lumps or apply some self levelling screed before fitting the boards.

What is the insulating U-value for the 10 mm board?

No idea but they are made to go under electric heaters and I have them in the bath room and they work very well

Can these boards be used on bathroom walls to tile on?

No these are not designed for wall tile installation
