Insulating Reptile Room Floor

[tikroh]

Hi all,

Quick question I hope someone can answer.

I have laid all of my insulation down in my room and got the floor all level.

How do I finish it off now?

Do I need a Vapour Barrier or DPM before the floor boards or do they sit straight on the PIR Insulation (Kingspan)?

I have a DPM below the PIR already but given it will be a humid little room, I am not sure if I should add another layer on top?

Also, am I OK to either expanding foam, and / or add Aluminium foil over gaps to seal it all up?

Thank you!

Kingspan is covered in foil which is a dpm.
Foam or tape will make joints air tight
