hey bekkyboo7 things to consider with aluminum doors and windows, they have lower maintenance and better weather seals..... in saying that the color is a big consideration, white is great although i generally use anodised silver, this way it often blends with the backgrounds better depending on your outlooks and views as well as it is very neutral against furnishings and coloured feature walls. anodized is a much nicer finish than powder coating as well as it has no sheen to it and looks "softer" its my design you have in the photo attached to this conversation cheers adrian

Hey Bill, what decision did you arrive at for these doors? Would love to see some pictures!

To change to cavity doors you will need to remove the wall each side of the doors to accommodate the cavity housing. Normal sliding doors would make a difference but the problem with them is they never stay totally closed and they do become quite noisy and annoying. This problem also applies to double cavity doors. The other option is to use bi-fold doors, they won't intrude into the room as much. Do you really need two doors there at all and is the glass above the doorway necessary? My personal preference would be to fill it all in and just have the one door to the room. You could even re-use one of your doors.

If they are timber sliding doors as per inspiration photo, then I would do vertical. It is completely different to your workshop roller door, so will not matter. Even if you did Colorbond sliding doors, I would still do vertical.
