Why twin wall polycarbonate is more popular than glass

[@sillydog70]

I like twinwall polycarbonate But I also like the fact that I can get it through Home Depot “windows and doors “ is this section I think you need to look for guys talk to them they get it and whatever thickness you want and length

[@pauldhennessey]

Thank you for the info. Will this material bend to a radius?

[@PIFDUDE]

Thinking of going for plastic panes in the greenhouse I'm renovating. Should twin walled plastic be used for both the sides and roof or could you use a mix of single and twinwalled? What are the benefits of single panel plastic?

Great video Thanx for sharing

[@Mrjboomseedco]

What’s the biggest you can find for sale I have massive tall and large plants I want to grow in a greenhouse but my plants get huge?

[@whatinspiresu]

theyre crazy! I heard everything. Im sold on twinwall poly!

[@sillydog70]

whatinspiresu Twinwall is the way to go but hell if you can afford it they even have triple wall if that’s the name of it Which would be even better if you can afford it

[@sillydog70]

I like the Lexington cream wall polycarbonate because one shipping is free fungal send it right to your Home Depot and possibly to your house I’d ask first

[@sillydog70]

Either way you could go to Home Depot and check out a sample of the product see if it’s something you’re interested in they sell smaller strips of it but what you are is the bigger full Sheets

this is a great video

[@northwestone1]

What did you say ?

[@z.weertje7209]

In Europe we use hammerd glass, the same glass you have in you`re car. It does not break by medium hail and if it does it is not sharp and is in a thousand pieces.

[@sunnybunnyranch]

Z. Weertje can I get that in the USA?

[@dougiequick1]

Will the quality poly fit into the crappy harbor freight greenhouses? I'm just saying if that is what someone already has to work with and they need new panels? Will the good stuff even fit?

[@bootangy]

they go green?

[@DragonsREpic]

[@tomyris8648]

Pretty

[@sillydog70]

I also believe that Home Depot will ship it right to your house

[@enuajsifoto]

I have to agree that glas is fragile and will not withstand the impact like polycarbonate will but If we need polycarbonate to protect the plants from the "sun burns" then the Nature did pretty good surviving all these milleniums without it:) Also the idea of keeping UV from the greenhouse is a questionable one as in the middle of the winter I want all the heat I can get from the sun - afterall that's the reason for building the greenhouse.

[@maximilian333]

+enuajsifoto generally these poly panels block about 20% of UV. plants normally grow near or under or around other plants which naturally blocks a certain amount of sun/hours from reaching that plant, and some plants do better. Having one flat panel over my container plants during August prevented scorching and led to crazy deep green lustrous growth in my california container garden this year. I was having problems with the combination or dry air here and the hot weather no matter how much I watered. in Ohio or Oregon you might not have these problems.

[@a2ashraf]

+マックスシュッツェ Do you happen to know if the room temperature is increased? i.e i understand how light may be refracted to stay inside and not leave, however what about heat? Does heat come in and stay in with 'twin polycarbonate'?

[@maximilian333]

Yes. Most greenhouses trap heat and most greenhouses have a fan and ventilation openings or flaps to remove the hot air. Especially in places with hot weather. And yes generally more layers will trap more heat from escape. The real purpose of twin wall is to prevent heat loss so that plants can continue to grow for a longer season, especially peppers and tomatoes which stop growing when temperature is below 50F. Then of course keeping a greenhouse above freezing temps can allow one to grow lettuce cabbage etc. throughout the entire year in places like Oregon, Washington, Ohio...

[@JohnGuest45]

The heat lost via thermal bridging of a typical aluminium or steel greenhouse frame is far in excess of any insulation value provided by the twinwall polycarbonate. Timber greenhouses are far superior in this respect :)

[@alanbrown397]

Agreed but you can always use large sheets of twinwall and cover over the frame entirely instead of just in between like you do with glass panes.

[@jimjaam1983]

So I should put sunscreen on my tomatoes then

[@vitadiaz4864]

Can twin wall polycarbonate roofing sheets cut and sealed in a curved line?

[@MrCheckitout123]

i know they have rolls Soleedex i think is brand name, it is thin and can be model around hoop houses.

[@paulmaxwell8851]

Twin wall and triple wall polycarbonate is listed as "capable of being cold-formed around curves" by BW Greenhouses. I'm about to try it myself, so wish me luck!

[@bootangy]

@@paulmaxwell8851 how did it go? is it green yet?

[@dayriderschat]

COST ?

[@andythedarkone1982]

You can get 4' by 2' sheets for as little as £4 per sheet, providing you buy on the internet and multiple amounts, pack of 10 for £40 with shipping is a common deal.

[@leedoran7981]

[@elainecloutier2764]

how about heavy snow here in Canada?

[@MrCheckitout123]

i have 6mm, with a 32% slant roof. the snow really does not stick to roof due to the heat buildup. i have had 1 foot stick over night and it was no problem. my GH roof is 2x4 rafters At every 2' with 6mm twinwall covering screwed and cualk'd.

[@alanbrown397]

what was the surface temp on the inside? FWIW I noticed that you can get up to quad walls in the UK - specifically for things like conservatories and minimizing heat loss.

[@paulmaxwell8851]

We get up to 8 ft of snow here, up to 3 ft at a time. Polycarbonate can take it, IF your greenhouse frame is strong enough.

[@reggaetony2806]

Lots of ignorant comments here. One guy brought up that if youve ever been burnt on your side window arm while driving? Making a good point in the summertime on long road trips the glass sorta magnifies sunlight on your arm and even hurts.

[@mihaiilie8808]

Your the ignorant ,because glass blocks a part from UV so you get less sunburns than without.

[@carlosarango7210]

Yes, you cannot get a sunburn behind a window but UV is a powerful mold killer. I am not expert with greenhouse but is is it useful for the plants to install a couple of UV-c lamps in order to sanitize the greenhouse?.. Just like they are sanitizing hospital rooms?

[@paulmaxwell8851]

Please see my comment above and click on the link to the University of Glasgow. UV harms plants and they have mechanisms to protect themselves. Put a plant under a UV lamp and see what happens!

[@reggaetony2806]

Put a glass patio table over your lawn and see what happens son. In less the 3 days youll have dead burnt grass. A green house is a man made object. Any time man is interfering with nature he may violate some natural laws

[@mihaiilie8808]

@@paulmaxwell8851 UV harms every living thing but its still essential for health of even plants. You get enough UV through polycarbonate and glass. They block UV but not all( i measured myself with an UV meter used for lizards , snakes and coral reef light tester.) Somme plants need more UV than otthers to regulate their cycle of life,just like they need cold in order to shed their leaves for winter. Not to mention the complicated organic chemistry and the proceses we dont understand iet,involving the UV spectrum.

feel lucky, I only have a right speaker so I had to skip the vid.

[@sillydog70]

Just got to Home Depot and ask them I’m sure they have samples

[@xbeanx3000]

Is it possible to know which side has the UV protection 'after' the protective film has been pealed off and thrown?

[@paulmaxwell8851]

Hmmm....that's a very good question. The Thermaglas polycarbonate from Palram, the world's largest manufacturer of greenhouse glazings, is coated on ONE side with a UV coating. It DOES matter which side is up. You should email Palram your question. Klaa2, you are mistaken. Polycarbonate is NOT naturally UV resistant. Try putting ordinary polycarbonate out in the sun for a year and see what happens.

[@TheLookingOne]

What is the typical lifespan of twin wall poly?

[@sillydog70]

TheLookingOne If memory serves me right it’s about 10 years

[@paulmaxwell8851]

Easily twenty years plus. I have friends with a 22 yr old greenhouse and their glazing looks great. DON'T use the Home depot stuff: it is NOT UV resistant and lasts a year or two if you're lucky.

[@Thewizzardof9]

I thought the plants needed the UV light to grow.
