Hi Peter

I designed and built the observing hutch in the projects section and found that just using a single skin canvas flysheet led to condensation forming on the underside of the canvas and this could drip onto the stuff inside. Fitting a 3mm closed cell foam mat underneath the canvas prevented the dew forming as it acted as an insulator.

So, with any single skin fabric tent, you may get condensation forming on the inside surface and if the material is touched or maybe shaken by the wind, there is a chance that droplets may drip onto the work surface below.

A cardboard box does not appear to suffer from this as the cardboard just absorbs the moisture, but eventually turns to mush!

Cheers

Dennis
