Anyone got experience of insulated roof panels?

That is very impressive, but it has a fair bit of support. I was astonished at the 9m span without any supporting framework.

They do have internal support inbuilt- you just can't see it...
That's why the insulated roof panels are so 'thick' for the longer lengths compared to the shorter ones like mums 6m or my 7m ones- all their internal framework is hidden in the insulation...

The mob that made mums actually has an 'arch' inside them for their longer spans, with a bottom tie between the ends holding them together, before the entire thing is covered with the bottom 'interior roof sheet' and filled with expanding foam- (I'll see if she still has all the paperwork as it had some diagrams of how they were constructed internally)

Mines pitched and well braces because of where we live.

I posted on here about rebuilding a shed asking about roofing options and someone suggested structural insulated panels. They look great. I was wondering what experience people had with them and where was best to buy from?

In particular what is the maximum span that is safe? The specifications say no more than 2.5m. Is that a hard and fast rule, or would people be happy increasing that for a shed / workshop? I have a 3m span and life would be a lot easier if I didn't need purlins!

Thanks.

I used them for my workshop at home, approx 5m span, went with from memory 180mm thick panels. If I ever build another would definitely use again and would most likely make the whole thing from them. I will try and dig out where I sourced them from, sure it was a guy on eBay that buys up slight seconds, over orders etc

Dunno why- my big shed here (from a different mob) is 9m x 21m total- the main shed part is 15m x 9m with a 5m x 9m 'leanto' added on to one side, and has not a single post internally except in the walls...- and its rated to cyclonic conditions... (rated to Region D Category 2 cyclonic conditions- rated at withstanding a wind load velocity of 88 m/s or 316kph)
It doesn't have the insulated roof panels, just conventional roof sheets, (I actually looked at replacing the roof during the construction with them, but as it was a 'kit' shed, I ended up not bothering- it already had rolls of insulation supplied with it)
Only the two 'ends' have posts in the walls in the main shed- otherwise it is a totally 'empty' area 9m x 15m- no posts at all

It's not even the biggest in their range by far, but it was the size I needed to fit the truck and trailer into lol
The tilt-tray fits in nicely- you can still walk around it with ease patio roof panels...

Just wondering if anyone might be able to chime in about Bondor's or ARCPanel's all-in-one insulated roofing panels.

We've received indicative costing for our new build, and now have to find ways to significantly trim costs.

I'm not sure how much saving is possible, but logically using such panels could save on trusses, and labor involved in constructing a multi-layered traditional metal roof.

When I mentioned it to my builder, he flatly refused such an idea, saying that when the Colorbond sheets start to corrode, we'll have to take off the entire roof to replace it... I don't see it being such a big problem. After all, it's going to take years, and replacement will be a planned thing and can be organized efficiently and quickly.

Have I forgotten to consider other major potential problems?

The sheets should have some stated life, so find out what that is first - if it's reasonable and you want to use them, then do so. They're probably very similar to the sheets we use over here, but they may be slightly different, so maybe ask on a US forum? At the end of the day, the sheets do a good job and are quite labour saving, as you point out.

As far as the builder goes, he's working for you, so should dance to your tune.

The Colourbond sheeting used on my big shed has a 30 warantee- that the powdercoat won't fade or discolour in that time!!!
As for the actual sheeting- well 30 years at least, but most people expect them to last multiple tens of decades....
