Isogam or white insulation? which one is better?

[volghan]

I want to tile the roof so I was looking for executives and saw "white insulation". It's more expensive than isogam, but it has some benefits, if true. Has anyone had the experience of using white insulation? Or any information about him?

I found these two companies that have white insulation. If you know another company, please introduce me.
