Upholstery and egg crate type foams will not be rigid, and may not be flame retardant. EPS and XPS construction insulation foam are lighter weight, more rigid, and could be covered with batting and fabric. They come in 4'x8' sheets, but can be cut with a utility knife into smaller sizes. They are available from a big box home improvement store like HD or Lowes. Not sure if they are flame retardant. Depending on how large a piece you are mounting, I would think they may be light enough in weight that they could be mounted to the wall with 3M removeable hangers of some sort.

The size of the pool is 6m x 25m x 1.35m depth.And we have though of going for 48mmx48mm glass mosaic tiles of different color combination. The reason is that we felt that going for a smaller tile might be too much busy on the overall looks and also too many grout lines would be seen. Wheres as the 48x48 tiles would be much relaxed in the pattern and a bit more easier to maintain. What is your take on this? Thank you in advance.

Given the very large living area, the USP of this apartment, there are a variety of screens available which can be used creatively, mobile or fixed, see through, translucent or opaque, full height or part, etc to divide the spaces and yet give a free flowing look of a large open space, the light and views from the large windows.
