Greenhouse Panel ???s

[Marco67]

Looking for input on glazing, I will have a carrige house style barn with panels down the lower back half of roof.

Have any of you guys found a rigid poly or fiberglass panel with light transmission over 85%.
I've found This @8mm with a light transmission of 81% and R of 1.7
And This as recommended by Anthony C
Problem with the second product is just a general reference to 85-90% transmission and no R value listed, they also seem to have a lack of installation hardware etc ... I am looking for a "tight" finished look and performance.
I also hear there is a new product by Lexan called "zig-zag" with over 90% light ***** and an R over 2, but I can't find any US dealer.

Thanks for any help
BTW I am on the coast of New England (Cape Cod) so wind and snow load are issues. I fear that the single layer sheet products will not suffice.

I am using 8mm panels from farmtek they have good insulative gualities and have withstood over 100 mile winds

also you can provide framing to acount for snow load .I used treated wood and painted it with a good white siding stain(oil based)to prevent contaminants from the treatment process . and I used the screws with 1" washers to fasten the panels,but in hinesight I wish I would have used the aluminum exstrusions they sell . there is a pic in my gallery that shows one side and how it is built btw I paid about 40 bucks for a 4x8 and it has a ten year warranty

Cool,
Thanks for the response..
Honestly I was set on ordering the 8mm from sundance they are ~$1.70/ sq ft (I need ~700sq) and ship from 1 state away, so the price is about the same.
The only reason I'm hesitating is the light transmition @ 81%

I just looked at Farmtec and didn't see any specs were they able to provide you with them ? or maybe I missed them on the site?

What part of the country/ is it plenty of light ? how long have you used them ....Mind if I go on ? LOL

I live on the coast as well , the outer banks of carolina. been up for just over a year and all seems well. I actually have a white shade cloth on there also 30% I think

 

[Marco67]

Thats what I needed ..Thanks
and sorry for all the questions ...it did seem strange that everyone was recomending at least 90% then using shade cloth
