“Plastic” and “durability” aren’t usually words that should go together, but in the case of greenhouses they can.
Long-lasting polycarbonate is worth considering as the covering material for your greenhouse, especially when compared to the traditional use of glass.
In the case of modern tempered glass, rocks and hail shatter the panes with little effort. Alternatively, polycarbonate sheets are known to withstand the strike of a hammer. It has been mentioned by some that an advantage to glass is the visibility of plants from the outside, however current advancements in technology have resulted in the polycarbonate sheets maintaining better clarity than glass.
当考虑到绝缘性时,玻璃也不太可取。Polycarbonate is close totwice as effective at insulation than glass. Looking at the greenhouse as a holistic system, the increased energy savings from effective insulation may make polycarbonate greenhouses more eco-friendly than a glass one.
Light is also diffused differently with the two materials. Polycarbonate covering diffuses the light coming in, causing light to reach areas of the greenhouse that it wouldn’t with glass. U.K. gardening expert Bunny Guinness alsopoints outthat polycarbonate protectsnaked gardenersfrom almost all UV rays that are dangerous.
Polycarbonate has only come into general use for greenhouses in the last 40 years; much experimentation is still taking place. You can research the latest options on your own and order your materials from a big box hardware store, or online.
我个人的建议是去找一位专家。
Polycarbonate greenhouse specialists have a wider variety of choices than the big box stores, and usually compare very well on price. Specialists will also carry accessories designed for building with polycarbonate, and many answer questions in person or over the phone.
We’re lucky to have one such specialist near Insteading HQ—Charley’s Greenhouses. They’ve been building and innovating greenhouses for four decades now, both for Seattle-area folks and on a national level through their website.
If you want to learn more about building greenhouses, not just polycarbonate ones, I highly recommendtheir YouTube series on the topic.
