Twin-wall polycarbonate - breather tape
Hello. I'm new to this forum, but am a longstanding gardening enthusiast.
I have experienced a problem with the installation of twin-wall polycarbonate panels in my small greenhouse, and I wondered if anyone else has the same problem. I was spurred on by Bunny Guinness’s article in The Telegraph, 10 Nov 2009, extolling the virtues of twin-wall polycarbonate panels to replace horticultural glass. During Spring this year, there were suddenly several suppliers selling polycarbonate online at very tempting prices. I plunged in and bought new panels, together with the aluminium tape and breather tape for sealing top and bottom cut ends respectively. I replaced all the roof panels of my greenhouse, and all seemed well. However, less than 3 months later, the breather tape has come unstuck on all panels, allowing debris and mould to start moving up, inside the channels. The supplier denies hearing of anyone else having this problem. Please can anyone throw any light on why this breather, ‘anti-dust’ tape has failed to do its job? |

My reply is not very helpful I'm afraid, in that the same thing happened to me when building a car port, I suspect however that part of the condensation/debris that occupies some of the channels came from an inadequate seal on the centre fixing buttons which I had to use because the sheets were quite wide. I've just lived with it, however I can appreciate that a clean car port roof is not as important as a clean greenhouse roof. Regards Don |

This tape is not weather proof it is intended to go beneath a plastic trim. I too had this problem. I got round it by fitting weatherpoof tape to the bottom edge and sticking a few pinholes in it.Seems to be OK at the moment. I had plastic trims but the snow just slides downand pushes them off. |

Can anyone suggest a safe way to clean up the channels before putting on some new barrier? Cotton wool 'buds' dipped in clean water? Thanks |

Thanks -- MrsTrellis- Hide quoted text - - Show quoted text - Hah, You have a problem there! I had to take panels off & fill them up/soaked with bleach. Then hosed them out. Still didn't get rid of it all. Panels only go on one way up BTW. The outside is UV proofed. They will crack up eventually if you fit them the wrong way. |

Wrong sort of breather tape possibly, or improper application of it to a greasy surface so that the tape did not stick as well as it should. Mine did eventually come unstuck after about 10 years. I used hitack weatherproof aluminium tape on the ends that would be exposed to the weather and the breather tape on the dry end under the aluminium ridge. Regards, Martin Brown |
