Thanks @JuneKnow - yes I’m in Toronto and definitely need to consider seasonal temperatures... but still love the look of full glass. Is there any way to integrate or do people put screens on the door areas?

The other way to handle it would be to extend the roof line and build a screened in area around the patio. That way, you can open the glass doors/wall entirely but still be protected from insects.

Yes thanks! We have been contemplating that as well....

Many of the manufacturers of the lift and slide also offer screens. They are usually the retractable type so you don't have to deal with them until they are needed. After market is also there (Phantom and others) but they aren't cheap as you can imagine.

Some screen, like stainless, uses finer wire. Less view is blocked.

I understand your point but you need to keep in mind your location and climate.

Thanks for all your thoughts!

I've installed Marvin Bifolds on larger opening with the roll-up screens. Colder climate here. Customer loved them. Very expensive and requires a highly skilled installer.

They do them all the time here in the PNW. Why, I dont know. It's not the bugs so much. It's the rats.

We live in Vancouver, so not same climate, but we still have screens on our sliders and all windows. I don't even notice them though on the sliders. The weave of the screen is very thin.

I live in New England and can't imagine a life without insects. But...do you have screens on your windows? At a basic level it seems like if you need screens on your windows then you will need screens on your doors as well. Maybe even more so, don't you have mice or snakes where you live?

I'm in Toronto too and wonder what kind of view you have that would justify the expense. Because as you have said, you'l definitely need screens for the mosquitoes, flies etc.

When I first moved to CA I was surprised that none of the sliders or french doors had screens. There really are no bugs! We usually had a back door open year round to let the dogs have access to the yard, and the only bugs we get are a fly once in a while. Tree rats can be a problem too, but I never worried about them with the dogs patrolling the yard.

Why not do a basic 6 ft wide x 8 ft high slider and do fixed 8 ft high window panels on either side? That will give you the wide open views without the cost of expensive multi-slide doors.

You manage bugs with screens unless you live somewhere that has very few bugs. Wish I could say that about where I live but its the complete opposite. If we had the slide/lift glass doors we would never open them or we would have bugs galore in the house along with mice and snakes. My husband would also be a bit up mess. He is a bug magnate.

Like I said we don’t live in a buggy spot, Vancouver, but we do have screens.

I would get invisible screens in your case. They retract and pull out as needed. People love them.
