## Questions & Answers

**Q: How heavy are these 10mm thick boards**
A: 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.

**Q: Want to use under vinyl click in garage with lumpy floor would this work?**
A: 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.

**Q: What is the insulating U-value for the 10 mm board?**
A: No idea but they are made to go under electric heaters and I have them in the bath room and they work very well

**Q: Can these boards be used on bathroom walls to tile on?**
A: No these are not designed for wall tile installation
