2.5m * 3.2m triple glazed lift & slide

mrsWhippy

Hi,

Does anyone know who might be able to provide a 2.5m high, 3.2m wide triple glazed lift & slide door?

Some of the companies I've been to are saying that this height is not possible due to the weight of the triple glazing.

Cheers

If the TG is say 15mm in total, then its in excess of 300 kg, 2.5 by 3.2 by 0.015 by 2600 kg/cubic meter which means a crane for installation.

You then consider the coefficient of friction from here
http://www.engineeringtoolbox.com/friction-coefficients-d_778.html

taking a figure of 0.16 means about 50 kg horz force to get it moving, assuming every thing is fully lubed up, which will work wonders on the shoulders, lower back and discs.
Its all very well getting gear like this when you can bench 350 in the gym but as one gets older.......

Just as well I won't be carrying it in myself so

Edited to add: I just copped on you're talking about actually OPENING the door. Ah ok. The penny drops. Wonder has anyone got something similar installed they can share their experiences of?

Have a 2.1 meter by 5.3 meter lift and slide by Internorm which while not as tall is a lot longer. Over 500kg, Triple glazed, passive rated and opens with a baby finger. They have one roughly 3.5 meters by 2.2 meters in the showroom I visited which would be fairly similar to what you're after. The website states they do up to 5.8 x 2.8 meters which is huge.

We did find most of the companies we approached couldn't make it this size. Can't remember exactly but roughly 4 were able out of 10 we contacted.

Excellent stuff. Thanks.

We're waiting for a quote from Internorm actually. What showroom are you talking about btw?

I drove all the way to Enniskillen. They have a Galway showroom and Dublin too but not sure what's in them. The Galway showroom wasn't open when I was looking which is why I went to Enniskillen. Just give them a ring.

only half of it will lift and slide

What is your preferred type - aluminium or timber aluclad? Large sizes like this are available in aluminium. Contact local companies that offer Schueco or Reynaers.

Preferably alu-clad to match the windows, but I suppose aluminium might also look ok provided the u-values will all be similar? Getting the idea alright that this might only be an option in aluminium ... and not really willing to compromise the size of the door.

Thanks

i have a 2.6x5.3m lift and slide triple glazed aluclad (i.e. 2.65m width half opening section) and it is a disaster. Door is very heavy to operate even though they used top quality door gear. Had looked at internorm and seen one of theirs in their showroom in Coleraine but went with another company who since went bust so i have a local joiner who is going to take a look. One bit of advice i got from another company (and unfortunately ignored) was to have a single opening door beside or in the same room as you might get a little tired of opening the large slider everytime you want to go outside (even if it is working properly)

Doing it again i would have put in a smaller door, no higher than 2.2m...maybe next time!!!:p

Same principle often ignored when fitting electric gates on front driveway:)

We will have a utility door but its not beside the sliding doors exactly. Though that's a good point. Its hard to imagine the scale of a 2.5m high door. Although ceilings will be 2.8 so don't really want a large blank section/lintel over the doors either.

Would concertina doors be a better option do you think? The disadvantage is that it'd be broken up into 3 panels rather than 2 for the slider.

bi fold doors would (most probably) be more expensive!
