Greenhouse Louvre Windows?

[country-girl]

I have just bought a second hand greenhouse that needs a couple of windows replacing. Would it be worth the expense of fitting Louvre Windows? I read that these windows can be a great asset to a greenhouse (obviously for air circulation purposes) I just dont want to waste my money if there isnt any real point if the roof window will do a good enough job.
Thanks.

My Dad has louvres at the bottom of his GH, and they make a big difference in air circulation. One is front right the other back left. I'd say they're worth the cost.

Wilkinsons sell one for £20.00. Not sure if that includes glass.
Some others I have looked at don't include the glass so be careful.
Also consider an automatic opener.

I have one in my home greenhouse oposite the roof opening. Both are on auto openers and invaluable in the summer when it can still be quite cool when I go out but baking my lunchtime. Well worth buying.

I have an auto opening window in mine, it was money really well spent

This is what Rhino says about ventilation (isn't it ironic that the empty bits in a greenhouse cost more than the glass bits?) :

"Adequate ventilation is absolutely crucial ...In designing the Rhino (except the Basic)we aimed for the ventilation to equal 1/3 of the floor area of the greenhouse. This is a very tall order and one that we believe no other greenhouse comes close to achieving.

We had to design special roof vents, two and three times the normal size in order to reach this goal.
We also increased the size of the louvre vents by 40% for the same reason.
Ventilation is expensive, so it will not surprise you that most greenhouses are sold with inadequate ventilation in order to keep the price down."

I have a louvre in the end opposite the door as well as a auto roof vent as Alison said a godsend if the weather hots up unexpectantly.

Not sure if this applys to all B&Q stores but I picked up a louvre window pack today reduced from £34 to £15. They had glass & polycarb versions all reduced.

I had a louvre fitted in the bottom of my greenhouse and find it excellent for providing ventilation on a windy day when there's a risk of top opening vents catching gusts and maybe shattering.

I've got my auto roof vent fitted and been thinking about getting a louvre next, my greenhouse is glass so does that mean I have to fit a glass one or doesn't it matter which.?

The one that I got was for glass or polycarb. The only difference was that I had to put aluminium edges along the polycarb to strengthen it. The glass just slides in the grooves.

Thanks bigmally I did wonder how they fit, I'll go measure in between my uprights.

That is a bargain Bigmallly thanks. I will have a look on the web to see whats on offer.

[Bigmallly]

Not sure if you will find one online. I went in the store and they were just on the shelf near their greenhouses........good luck.

Just checked online. None there. I will have a trip in store. Id hate to miss that offer! Thank you.
