sorry for my ignorance.. pero di ba pwedeng magtayo ng isa pang pader na nakadikit sa existing pader. wala talaga akong alam sa construction eh. ano po yung floating at yung slab?
Dude, to make a long story short, you need metal studs and metal tracks like these (which measure 2.4m or 3m long):
Then, you need your insulating material (ie rockwool or fiberglass). I prefer 60kg density 50mm rockwool slabs that come in 0.6mx1.2m sizes.
You also need gypsum board. They come in 1/2" and 3/16" but I prefer the 1/2" slabs. They are sized at 1.2mx2.4m. Doubling or tripling the boards works much better.
For your tools, you need a putty knife, power drill, a riveter, and also, you need some gypsum plaster tape, rivets, gypsum putty and gypsum screws (they look like wood screws, only black in color).
To make a long story short, you need cut and rivet the metal tracks and studs to make metal frames sized at 0.6x1.2m. You have to mount the frames to the celing and floor against the concrete wall) where you shall stuff your insulating material in. The gypsum boards are stuck to the metal studs using a drill and the gypsum screws. Some say it would be best to put some foam tape on the studs where the screws shall be drilled.
The concrete wall will be the innermost layer, the rockwool/fiberglass as the middle layer, and the gypsum board as the outermost layer. Sa madaling salita, GYPSUM/ROCKWOOL/CONCRETE WALL sandwich.
