insulation Quinn therm 50mm in conservetory

[Ajax123]

Quintherm is as far as I know a standard 350Kpa polyurethane rigid board similar to Kingspan or Celotex but it does not normally have a foil backing which makes it a bit prone to point load compressions e.g. when you kneel on it. The other PU boards do this as well but it is not usually so noticalble cos the foil back holds it a bit more rigid.

Not sure about the SLC or other stuff though I have only ever seen it used where a screed is put over the top when the impressions don't matter too much.

Can't imagine SLC and tiles direct to the board being very succesful though. What sort of overall depth have you got available over the insulation

Thanks Ajax and Dave.
went with the original plan. SBR base 4to1 wash with sand cement mix and then rapid set flex tile adhesive to the Quinntherm. 6mm Hardi backer board on top fixed with standard set tile adhesive solid as a rock. laid my ufh and the SLC to go over tomorrow.
this base feels very strong and ridgid now I have the 15mm to play with for my tiles
Happy Days:hurray:
Thanks for you advice guys.

Hi Guys thanks for your advice i have finished the job and with great success the customer was very happy that he didn't have to Waite months for a screed to go off
this system worked very well and I will try and post some photos of the project
