## Questions & Answers

**Q: Would this be suitable to fibre glass onto for a water feature/pond?**
A: No the panels do not bend. They will snap.

**Q: Could you wallpaper directly on to these**
A: Shirt answer no. You need to put drywall over it. Any time you put a decent amount of pressure on Xps foam it marks or crushes.

**Q: How to i attach these to a concrete floor , i.e tile adhesive and can i self level over the top of them**
A: I just sat the boards on top of the concrete. Didn't use self levelling concrete after. The boards done the job

**Q: Would this be good as a base to insulate under an above ground pool? Im looking to reduce heat loss**
A: Quite possibly, provided weight is evenly distributed over them.
