I am about to insulate a wall. I am comparing Jablite (not basic polystyrene) to PIR board. I can make the wall thicker when using Jablite rather than PIR so thickness is no problem. It will not face compressive forces so no compressive strength issues. The cost seems to be about half. Both products seem to be combustible. If I understand it right, PIR encapsulates a gas which leaks out over time eventually reducing the product to the same u-value as Polystyrene. Why shouldn't I use Jablite?

Hi all!, I'm new to buildhub and hoping someone can help or point me in the right direction! I'm in the process of installing a floor. It's a block and beam floor. I'm now at the point of installing the xps insulation over the top before ufh (water) and a screed. The insulation I have received is danosa danopren xps pr-p. Their website states this is for the wall with a compressive strength of ≥ 200 kPa . They make a floor insulation with a compressive strength of ≥ 300 kPa. I have looked at Celotex insulation as a reference who state their insulation is 140-150 kPa. I will be installing rebar mesh on top of the insulation to hold the ufh pipes down. Does anyone know if this will be ok? I have already done this to another floor before I realised! I'm not going to dig it up unless something happens but would like to know for sure with this next floor. Many thanks in advance. Jason
