    I'm not sure if I agree with that. I had thought that the louvres should be placed low to pull in cooler air to offset the amount exhausted by the roof vents. That's the way they show the placement in all of the adverts I've seen. I could be wrong but :what:

      The roof vents are there to get rid of the hot air, often the lower parts tend to get stagnant especially during summer/ Autumn if there is a lot of leaf growth.
      So opening the door at the same time as the louvers keeps an airflow and dries out damp foliage.

      I cant really see as the aspect of the louvers is really of much concern.

        The Louvre should be located at the rear of the greenhouse.

          Personally when we get hot spells.:lunapic 130165696578242 5:
          Which is not very often:snork:

          I just whip out a few pieces of glass, by releasing the clips.
          But that might be easier with some types of glazing than others, and possibly very difficult with the more expensive types.

              No, SP, you didn't waste your money and you should fit it. My louvre has been in the Green House over 10 years and has been a boon. The glass slots rest in the arms of the louvre and even having them open slightly will make a difference. We get high winds every now and then around here but at no time has the louvre been a problem as it's always fitted sturdily just like the rest of the windows.

                @Spacemunkey you are a big poo. Now you got me thinking about putting a louvre in mine:doh:

                I just looked at the ones that fit
                Side Louvre Window Vent

                and I think it would be easy to put one in the door of my greenhouses. I had made retractable screens but this seems to be better.... and I've already spent enough :doh::doh::doh:

                YOU BIG POO!!! :)

                  No that was an exceptional summer;)
                  Last time was a couple of years ago.

                  Lori, putting a louver in a door seems a bit pointless to me, its much easier to just open the door.;)

                    @pete I was thinking if I only opened it a teensy, air would flow and the squirrels would not gain access. That's why I had screens but they are a little bit of a pain to open and close. Yes, what the heck am I doing that I need to go in there so often?...well, I rearrange plants and accessories like some people shift furniture:doh:

                      I agree, pete. You have a louvre to lower the temperature and flow of air so having it in the door when, as you say, you can just leave the door open and have the louvre positioned on the side or rear of the Green House seems more viable.:dunno::snorky:

                        I was being lazy. In order to replace a side panel, I have to remove the whole roof. Went through this last spring when I decided to replace the twinwall panels in the smaller house to polycarbonate for aesthetic reasons. And it was a long process. I figured if I only have to take the door apart, I would be looking at an hour or so instead of most of a day... lazy Lori... oh well, I think I'll work on a new design for screen doors. :ideaIPB:

                        Always fun to play with tools :snorky:

                          Well, if your Green House has plastic side, I would forget the louvre and, as you say go for Plan B and

                              Lori, I've just had a look at your link for side louvre vents, $149.99 that seems very expensive. I do admit I do not know what the exchange rate would be for British pounds £££ but here in the U.K. My louvre vent was £55. It's seems like a bargain to me compared to yours

                                Yes, I think the higher price has a lot to do with the fact that the Palram series of greenhouses are made in Israel and the freight to me substantially adds to the sticker price. I'm really am quite excited for you about building your greenhouse. I was thinking about adding another small one to my side deck - so I would need three louvres to put one in each house! Please post pics when you get going as I will be happy to watch your project move along.:)

                                About costs. So many variables in pricing in products between our countries. I am still shocked that your petrol is twice the price of ours and also the cost of accommodations is very high. I had been trying to plan a trip to visit London but the cost seems too prohibitive. I could buy a large greenhouse for the cost of one week there. :sad:
