How do you stop condensation on polycarbonate roofing?
Polycarbonate is hydroscopic and so can absorb moisture from the atmosphere and installations depend on ventilation to avoid saturated air in the cellular structure which will condense under appropriate conditions. The bottom of the sheets have breather tape fixed to them to allow any moisture to evaporate out.
Does polycarbonate crack when drilled?
Using the wrong type of bit can result in the tool grabbing as you are drilling, which can lead to chipping at the edge of the hole. That’s a real problem because chips can propagate into cracks.
