Not that I have seen - what we could do is a plantation shutter and then use a Crimsafe build-out to attach the security screen - you need to have it so that the shutter can open and it not protrude in to the screen - the challenge I see is that there will be a fairly large gap between each door to allow them to pass each other You might be better to look at using a commercial door section a slimline fixed louvre and then having your screen at the rear - this would allow a much better fit and also slide - but it would not be an opening type shutter Sorry best ideas I have for now - if you need anything else or me to do a rough sketch so you can approach someone in your area let me know Regards Heather

http://www.alufront.com - Google search - but really, you've got so many window and door manufacturers in Australia - unless the quality can be absolutely guaranteed by the builder and is SUBSTANCIALLY cheaper - why would you? I'd be asking him why he's so keen to use them and putting the onus of proof of quality for the product back on him - but that's just me and the way I think.

Dr Retro's analogy with a convertible are so true. We elected to wait 12months in our recent house purchase before embarking on major renovations. The magnificent view that we thought we needed to have stacker/bifold doors for turned out to be too breezy to have the doors open for more than a few days a year. So the extra wide mullions associated with this kind of door would be impacting the view for 99% of the time. In the end we went for extra wide sliding doors (3 for a 4.6m width) with the narrowest mullions we could find. As for your quandary re the corner post, how about a very small section solid stainless steel post? Along the lines of Miles van der Roh's Barcelona Pavilion?

are the new sliding glass doors double glazed? are the original windows single glazed or in need of replacing for any other reason? do you hate the beige colour? how many of the old windows can be seen at the same time as the new doors? ... inside looking out is the most important view for me but what do you like the look of?
