Palram Side Louvre Window

Sturdy. I've had it on my green house for about 6-months and it's great.

I took a gamble on buying this for a Canopia Bella. Many say it will not work, I had two different answers from Palram CS (Yes it will, No it won't). Figured I could return it if I had to.It fits fine but you do have to cut 1/4" off the two channel pieces that run across the top and bottom to fit between the vertical panel holders on the end wall. I still need to find something to fill the gap under the window (to the top of the greenhouse base) but I have some extra polycarbonate that I had to cut off to install the window.Can't speak to installing this after the greenhouse is built but doing it during construction was pretty straightforward.Operation is pretty smooth, works like louvered glass windows.

We installed the Palram louver after our palram 6 x 8 greenhouse was already up. Total time was about 2.5 hours. This was done mostly by my husband with me helping just a little bit pushing some nuts through the frame while he tightened them up.We removed the support system that was below the triangular piece in the back, as well as the Roofing on either side. I included pictures so you can see what we had to disassemble.The one problem we did have is that the half sheet of wall that goes above the louver and was included was cut irregularly and my husband had to re-cut that.But with near identical weather conditions the two days before we installed and the couple of days after… And with a fan installed in the inside to blow air through the greenhouse, I was able to lower the temperature by about 10°. We will install another louver on the side next spring.One thing to note… We have an automatic louver opener on back order. This is different from the roof vent automatic opener and the two should not be confused. Palram makes both openers and they will work best if you use the opener that is designed for each application.

Works great. Very happy with this vent. I highly recommend that you install this DURING construction of your greenhouse, rather than after the greenhouse is fully put together. I installed mine after my greenhouse was already built, and it was an absolute nightmare to install. Granted, I didn't have any help while installing it. A second person helping would have made things go a LOT easier. Your greenhouse will almost fall apart if you try to install the vent in an existing greenhouse. My greenhouse is the Mythos 6' x 8'. I don't know if it would have been easier with a different greenhouse model. After almost destroying my greenhouse and suffering a few injuries in the process, I'm happy to report that the vent works beautifully. You WILL need this vent to help keep your greenhouse from overheating in the hot days of summer, so buy it along with your greenhouse kit and install it at the same time to make things easier on yourself!

This item can not be installed between studs--too big. It can not be installed in standard 2x4 construction. The return window on it is extremely limited. Don't order it unless you are certain it will work in your project and make sure you immediately attempt installation to make sure it fits. They make it almost impossible to return.

This does not fit into the back panel opening for the Palram Harmony 6'x10' Greenhouse. It is 3/8" too narrow and so the window slates will drop out. If installing in one of the side openings it should be installed during putting the greenhouse kit together otherwise the one side roof and center side rail has to be removed in order to install it. Think about it carefully before ordering one after and not during purchasing of you're kit. Once the greenhouse has been finished it is a very good quality greenhouse for the money.

Easy to install and I definitely recommend doing this install as you're putting the greenhouse together versus afterwards. Vents open and close without any struggles and actually seem sturdier than the regular panels.

I read the reviews for the Palram Side Louvre Window after I purchased and received the product. I was most concerned after noticing that the window is not supposed to fit the Palram Snap and Grow greenhouse. Of course, I immediately thought about returning it before I opened the packaging. After reading the detailed review By rjeffb (April 4, 2016), I decided that I too could modify my greenhouse to install the louvre window. The benefit of having fresh air come in from the bottom of the greenhouse and exhaust out the roof was too important to leave out of the construction of my greenhouse.Yes, one difference between my installation and rjeffb is that I installed the window during construction of the Snap & Grow. I never had to remove window panels or struggle with braces or struts as I was able to place the louver in while building the greenhouse. As a result, I never had any of the problems that rjeffb experienced. In fact, I never cut the louvre panels nor made any modifications at all. Instead of installing a window panel in the middle of the back wall, I replaced it with the louvre and the small window that comes with the kit. The louvre slipped to the bottom of the greenhouse and the window fit nicely on the top. Admittedly, there was a gap between the window panel and the louvre, but I filled that gap with 7/16" foam insulation to keep the cold air out.I also purchased the Rion Automatic Louver Vent Opener which I installed at the same time. It was a bit more difficult to install as the parts didn't quite align. However, after a few adjustments to the opener, I was able to attach it to the louvre window's manual opener mechanism. It opens and closes as advertised with changes in heat/cold. So far, I haven't figured out how to adjust it completely, but I'll get there. I did notice this weekend the outside air temperature reached the mid 70's here in the Washington DC area, and the Louvre opened (not fully), letting cooler air in from the ground level.
