In garage Airchambers

[Geoff Kingston]

I was wondering if anyone has used an Airflow Airchamber or a Harrington Cair O Port and could give me some feed back as I am considering getting some for a building that suffer some roof condensation from the steel roof.
I was hoping to have had the underside of the roof insulated but my Builder has let me down with little prospect now of getting the job done this side of Christmas. I have had to discount the Carcoon Veloce as it is not tall enough for two of the cars, the Airchamber length wise will be a tight fit in the building and the Cair O Port is a bit shorter but I notice with that you have to drive over the bottom rail of the front frame to get in and out, will it distort over time and cause any issues.
Any advice will be much appreciated.
Geoff.
