TUFTEX Polycarb
Any one use this brand of plastic for their greenhouse. Would like to know how long to expect it to last.
I have 25 year old fiberglass and it is almost opaque now. Alternatives would be welcome. Thanks |

I cant say how long they will last but about the only thing better would be glass.

If you are talking about the corrugated panels that Lowes and Home Depot sell, they tend to have a poor reputation; they cloud up quickly.
If it were me, which means cost would be an issue I would rather have lumber-framed panels and poly greenhouse sheeting stretched over them. Snow will slide off if you angle them steeply enough, and the poly sheeting is about 1/10th the price of the high-quality rigid panels for greenhouses. You can also double up the poly and inflate the middle. Doing so will almost double the insulating ability of the poly. Here is a good link about r-values: http://bwgreenhouse.ca/R-valueU-value.html |

I have a corrugated plastic on the roof of my greenhouse. Its finally starting to show some wear after 7 or 8 years. When you clean it you need to make sure to follow manufacturers recommendations. Certain cleaner will make it cloudy.
