Good place for Lexan pannels www.sundancesupply.com

I dont give your idea much chance of holding up during a wind storm , driving rain or hot sun. Lexan desplays a lot of movement with weather changes so the install has to allow for that.

If your dead set on doing it have frames built for the lexan fasten with screws being carefull / a lot of care to allow them to be backed off durning removal.

Thanks, I appreciate your warnings - that's exactly the reason i posted, I don't want to go into this naively. But what is it you don't think will hold up? The glue backing on the Velcro or the velcro's strength? The glue is rated industrial strength and rated for outdoors, wet resistent etc. The surface I'd glue it onto is smooth aluminum. Maybe I'd need a wider strip of Velcro. 1" instead of 1/2".

Forget it Girl....by the time you went thru all of that ....
A. Your costs will be higher

B. Your project will blow away,leak like a sob, look silly and be hard to store.

C. Not have the value ratio you want.

We are ordering 1/8" acrylic sheets, cut to size by a local company, for our small screened porch to make it a 3 season room. After doing the research we learned that lexan will yellow because of the UV rays. The acrylic panels will be about 1 inch larger on all sides than the screens. The acrylic sheets will be installed using butterfly clips on the outside of the screens. We had our contractor put a removable panel on one side of the porch crawlspace and we installed indoor/outdoor carpet on top of weed cloth that we placed right over the dirt in order to have a safe place to store the acrylic panels during the summer months. Our enclosed porch has Lockdry waterproof aluminum decking so the the carpet and acrylic panels will stay dry while being stored.

So glad to read these posts as now, in 2015, we are facing the exact situation. We have large arches on both sides of our outdoor fireplace and need windbreaks in the winter. We are not concerned about having some air leakage. Our arches are 102 inches at the top and 70 inches wide. The clear plastic tarps that we have used for the past two winters have worked OK, but since we live on a golf course they do not offer the aesthetic look we are seeking. We considered adding some sort of folding doors, but want to preserve our view. We live in Houston, so will have these up from around mid-November through mid-March. Can anyone provide any updates to this conversation? Thanks in advance for any information that you can provide.

We are in the process of making pvc frames for our screened in porch and using 40 guage eisen glass for the plastic. We are stapling it to the pvc frame with stainless steel staples. Will bolt it on screen frames with stainless steel bolts to be removed in the spring and summer. So far it looks good. Will let you know how it worked out after we went through the winter months!

I am wanting to make my screened porch warm enough in the winter to be comfortable, high 40s or low 50s. Will this be possible with polycarbonate you mentioned? If not is there something that would make it those temperatures.

Thank you

I am trying to put much larger windos and screens in my add a room porch. It is made up of vinyl panels. What is involved in cutting larger sections out and will it work. Thanks

We put actual glass in ours. So glad we skipped on vinyl panels. They scratch and dull in time. Not windows. And a local glass company was almost the same price and delivered!

We are not trying to winterize our deck though. We are in Washington State and that would cost way more than we can afford. We used some boat carpe for the floors, kept the carpet 3 feet in from all sides so it doesn't take on water from the 1/2 inch gap under the sides. We did have to insulate and enclose the tin roof above with tongue and groove so it doesn't get condesation. If you are building, make sure you use real roofing, not tin roof. They condensate big time. That was our one big mistake.

We can store stuff out there, as long as we keep them in plastic bins. Nothing cardboard will last.

Even though the dirt under the deck has a vapor barrier and we have rain gutters, it's not enough. For air flow we put in 3 large windows that are nothing but wooden blinds.

I don't have pics of the tongue and groove yet. Besides a bit of moisture in the air, it's still pretty nice out there. We are going to get a propane heater out there. That will do it for us.
