Best hidden fastener system?
I am looking for siding profile to use with a wood siding hidden fastener rainscreen siding system.
I am installing on 4″ exterior insulation.
I had initially liked the Climateshield profile until I learn you have to use z-girts on 4″ insulation which seem like they’d cause thermal bridging and are more expensive than furring strips (this fastener requires no furring strips) – you can see more about z-girts here:
So now I’m looking at the Deckwise system which uses conventional furring strips and I think it has lower hardware costs than Climateshield:
Is anyone aware of anything better than either of these? Have any other recommendations?
Also a side topic – I am most likely to use Atlantic White Cedar for the majority of the insulation but I was also considering FSC certified Garapa (from Southern Central America and South America). I know the cedar would likely be the cheaper and most green of these two options.
The thing I don’t get is people saying to avoid the exotic wood for sustainability reasons but still advocating for Kebony which is grown in New Zealand (or Sweden if it’s the character grade rather than the clear which is more typically used for siding), shipped to Norway for processing, and then shipped to the US for processing and then shipped to the customer. Seems pretty clear to me that Kebony is worse than FSC exotic hardwood from a sustainability and carbon footprint angle.
Other than the sustainability/footprint how will cedar compare to a hardwood like Garapa for siding?
