Hi all,
here's a question for you, as you know i am having a few problems convincing my contractor that insulating my new swimming pool is a good idea. It has been suggested to use Kingspan underneath and around the sides of the pool. He is now saying the Kingspan will not withstand the weight. So i am trying to do my own calculations based on Kingspans own specifications.
So basically Kingspan are recommending Styrozone H350R which has a compressive strength of 300 kPa...which is 43.5PSI according to this online calculator -
Add in say 5 inches of concrete for the base of the pool which weighs around
2400kg/m3 (0.086 lb/in3) according to these websites-So, bringing this together-
water @ 2 meters deep = 2.9psi
5 inches of concrete = 0.43psi total weight on the Kingspan= 3.33psi well within the 43psi Kingspan say their product can withstand.Are my calcs anywhere near correct?! I doubt it, but welcome enlightenment and discussion!
Cheers all!
