What kind of SIP is it (wood, steel, MgO, etc) and what kind of core (EPS, urethane, etc)? What manufacturer?

The first problem is that Versiclad offer two types of panels; an insulated panel and a SIP, the insulated panel is NOT a SIP (Structurally Insulated Panel). It's almost a night and day difference between a structural vs. non-structural insulated panel.

According to the website the Versipanel is the SIP while the Versiclad is NOT a SIP. The Versipanel SIP only comes in OSB and Fibre Cement. You stated that it is a steel panel so that would make me lean towards that you do NOT have a true SIP and you actually have an insulated panel that is not structural.

Are you sure you have a SIP and not just an insulated panel?

Banana707,
The photo is really poor quality, it looks like a hand print or blistering.
As near as I can tell Versiclad makes both aluminum and steel composite panels, structural and non structural
Being based in Australia,I don't know if it is steel or aluminum?
Did you contact the builder or the manufacturer?
and what did they say?
most patio roof panels in the US would be aluminum

Hi,

It is really hard to see the damage. It is not very visible even when you see it and does look like a large hand print. When you push on the panel it still feels hard and like the foam is still in tact but when a handy man took a look he thought it was delaminating.
The handy man thought the panels were APS Versiclad and the measurements of the panels were 1000 x 4200 which is why we thought they were propbably SIPs as the Spacemaker SIP panels are 1000 in width. They could however be another type.
We just wanted to get some indepent advice before speaking with the manfacturer as we have never dealt with this before and I am not familiar with insulated roofing panels at all.

Banana707,
1000 is a very common width worldwide, even in the US.
Unless there is sagging or evidence od structural failure , I would not be concerned
I have seen things as small as a house fly that gets laminated between the skin and the core cause an ugly blemish ,since it looks like a hand print , it could be a something like a thin latex glove that got laminated during production and not caught by quality control
Tha fact that you said it is hard, means that it is probably not delaminating, but rather some foreign object laminated during production

Hi there,

Thanks for your advice. Whilst it looks a little like a hand print it is in fact much much larger and there is definitely some kind of bubbling / warping. There is no way it could be something that got laminated. As far as we are aware it has appeared over time and was not there when first installed.

Did you contact the builder / installer or MFG.?
