Hi Folks. Does anyone know what materials they are using to build these panels and how they are constructed? To me it looks like they are using some kind of vinyl material for the membrane. I would order from them and do my whole studio space, but I'm located in Canada and the currency exchange on top of shipping and duty fees will really kill the wallet for no good reason. Id rather just try and DIY my own and get similar results. Obviously they won't be as good at the GIK stuff because they clearly know what they're doing.
