Condensation inside perspex double skinned window

Post by Spiral »

Did a repair on the high top double skinned perspex window of my westy atlantic using method shown in one of the forums. Basically I split both skins in two and replaced the cracked inside skin using a cut sheet of perspex bought from B&Q. I then sealed with silacone sealant & clamped both skins together, left to dry overnight and refitted the next day. Before I sealed the two skins together I made sure that the two halves that went together were clean & dry. I'm now having a problem with condensation between the two skins :? Would drilling a small hole insde help clear it :?:

Sounds like you`ve got damp air trapped inside it, some original factory windows have small holes drilled in them, with plastic bungs to seal them. One of mine was steaming up internally, I removed the bungs and let it dry out for a week when it was sunny, I then used a hair-dryer to warm the inside face of the window (not to much) and then quickly sealed the bungs back in with a smear of silicone. The idea being that the air inside the unit would be warm and dry, then when sealed up it cools down and contracts forming a partial vacuum. Been fine ever since :)

I have seen something about putting a few grains of rice into the unit through the small holes, this stuff will sit in THE bottom of the unit and absorb any small ammounts of moisture.
Keep it real.
