Dr!pStop is the absolute BEST WAY to handle condensation in uninsulated metal buildings; it fights condensation without insulation. Specially designed air pockets store condensation and hold it overnight, then it evaporates back into the air as humidity. Since Dr!pStop arrives on the jobsite already installed, it is not only safer, but it saves the time and labor costs of installing insulation. It also protects the steel by adding another layer of protection from the corrosive elements found in livestock confinement.


Infinity Shield™ is offered in standard rolls of 4’x125’ Single Bubble Foil/Foil, Double Bubble Foil/Foil, Single Bubble White/Foil and Double Bubble White/Foil. We also manufacture a no seam 6’x125’ and 8’x125’ roll version of all the available SKUs. Infinity Shield™ is cost efficient and hassle-free. Additionally, the standard crushed edge tab (2”) will result in simplified overlapping. Our ultra-white bubble has a more opaque finish — a result of additives throughout all layers of the bubble.


rFOIL Reflective Insulation is a layer of heavy-duty polyethylene bubble, bonded to and sandwiched between metalized foil sheets. A white interior facing is an option. rFOIL is specifically designed to control heat gain/loss, and prevent interior condensation, in all types of post frame, metal building and metal roofing applications. rFOIL provides the best defense against the radiant heat transfer that occurs commonly in these building systems. The key is the aluminized surface, which blocks 96% of radiant heat transfer.
