My Architect has modeled our home with 4 ft sliding glass doors. Because of the modern design they really look good.
But I HATE sliding doors, especially to a Patio. And the ones I have seen are not very efficient.
A single swing french door would be more efficient but doesn't have near the amount of glass area, and I haven't seen them in a 8 foot R/O
Anyone know of a door set that might work? |

I just discovered folding french patio doors. They operate like bi-fold closet doors and open outward. It looks like they have good air sealing and locking capability. With an 8' opening, you would likely need a triple wide panel to accommodate that width in the folding doors (3 x 2'8" doors = 8'). One advantage of the folding doors is they completely open the door space unlike a sliding door which only opens half of the given door opening. One manufacturer I found is Jeld-Wen. They make a fiberglass line of folding patio doors as shown in the following link: http://www.jeld-wen.com/catalog/patio-doors/custom/fiberglass/folding |

How about European Lift and Slide Patio Doors?
Intus Lift and Slide
They also make a full glass French Door:
Intus Full Glass
I really don't want a slider, but their French doors do go to almost 48 inches. I will have to check them as they are Passive Haus.
Thanks

Does anyone have experience with how these (Intus) compare cost wise to Serious/Alpen, and service? |

Here is a quote I received for an Intus Lift Slide Patio - 10' 8" x 6' 8"
System: TERASA2
Color: White/White
Dimension: 3251 x 2032
Area: 6.6 m2
Filler: 1, 2, 3, 4: GrudSel4+16H+Grud4+14H+GrudSel4, Triple glazed unit with 1 tempered glass and 2 tempered-low emissivity
Ug=0.106
Sash: 1: Double Lift-sliding
Accessories: Double cyllinder, HS handles on both sides - 2.00 set
Price: $7,175.31 delivered
Other than a longer delivery time I doubt there is much difference in service. Dealers are available in most regions. Not sure how that price compares to the others you mention.

The dimensions for those quoted doors are just huge. I guess this price looks ok for 4 panel doors with all three glasses tempered. |

I was wondering why do you hate sliding doors. They looks great, occupies less space of your house, provides a lot of natural light to your interior and is not energy inefficient (http://www.windowchoice.ca/patio-doors ). Older sliding patio doors were said to be inefficient. But newer sliding doors are optimized for energy efficiency. Choosing the right material for patio doors also matter in case of energy efficiency. A vinyl or fiberglass patio door will be the best for efficiency. Also they will be very durable. |

Sliding windows and sliding doors are bad when it comes to air infiltration. Numerous building science studies and tests confirm this. The only exceptions to the rule are high-end doors like Intus and similar manufacturers that use high-tech lift & slide assemblies with numerous gasket seals to help seal the gaps. The inefficiency is inherent in the design of sliding windows and doors. It's not the material (vinyl, fiberglass, wood) and it is not the glazing, it is in the design itself. It's like the boxed shaped cars of the 1950's. The non-aerodynamic shape of the car hurts the MPG since it acts like a brick in the wind. A brick shaped car will always be inherently inefficient because of its shape. That is why Intus uses a "lift and slide" design. The patio door when closed drops into a channel so it can create a sealed area. 99% of other patio doors do not do this and simply rely on sweeps and gaskets that are never completely sealed since they must move alongside each other, so the fit is loose and will only keep getting looser over time from wear & tear. Here in the southwest desert, the exterminators state that sliding patio doors = scorpion and bug entrances. Layers of dust/sand can be found around the base of sliding doors because the air infiltration is so bad. Unless the design is high-tech like Intus where the door drops down into a channel when closed and utilizes numerous gaskets, you will never get a good seal. |

I have been using sliding doors for about six years. So far I didn't have any kind of issues. May be longer term issues? None of my friends who also have sliding doors for years have said anything about it. Anyway I feel it is a personal preference above all else. |

I have to agree with Lbear on this one. Patio doors are notoriously leakers, and ericnh, while you may have not noticed this flaw, it's definitely there. Lift and slide is the way to get around that. I made the choice to go to French doors instead. While my windows are Alpen, I made a small trade off in efficiency and went to Marvin Integrity for the doors due to cost. But the difference in price has diminished significantly as I keep getting nickel and dimed by Marvin for changes in sill color ($80 per door) and hardware color ($265/ door). I've got six of these. Marvin also wanted $1000/door on those that I wanted a high solar gain coefficient. Seems they don't sell many with that. Duh! With that price add, I wonder why😳 It seems Marvin has taken a page from the airlines. Low upfront price and charge out the wazoo for anything "special". |

I build homes on the Virginia Outer Banks and high quality sliding doors are the preferred door to prevent water intrusion. |

The intus lift and slide door is interesting but what about opening it for ventelation. At this price point there are no screens? |

Yeah. When you see crap like that, it makes going to a higher-end provider look way more economical... |

Yeah. Apparently they rely on third-party vendors. How...shortsighted... If you're dead-set on a sliding door, okay... Honestly, were it up to me, I'd just go with a set of tilt-turn doors. |

Try considering triple-pane patio doors which are even more durable and efficient than what you used before. |
