Mondays' work is done, and what can we see?
Not an awful lot, unless we're looking closely. First fix electrical is in place for the Utility, Gym, and AV closet. The joists have been fixed in place. And the AV closet is framed. Oh, and the old joists and floorboards have been sprayed for woodworm - they should already have been done over the years, but there are so many little holes around, for the cost of a can of treatment, it'd be silly to take the chance.
^^^ Joists fixed in place.
^^^ AV closet framed, and FF electrics in. Separate ring-main for AV gear, lighting ring also - lighting will be controlled by RAKO units in this closet.
The next few images are Sketchup drawings I made to assist the builders in visualising what they're trying to achieve wrt wall and ceiling construction.
^^^shows how joists are interleaved - such that the lower joists support the ceiling, the upper joists support the floor above. The two do not touch, so no sound is transmitted (in either direction) through the structure.
^^^the same image from a different perspective. Showing how the inner wall (that supports the lower joists) doesn't touch the outer wall either. Again preserving 'isolation', prevent noise transmission through the structure.
^^^more of the same, but also showing how there is to be insulation in between the studwork, and the leaf of the wall is constructed using double layers with a 'Green Glue' sandwich. In my case the double layer is one layer of OSB, then GG, then plasterboard (high density soundboard).
^^^and one last view of all of the above.
Again, off to work in the morning, and not back until Sunday night. I'll be relying on my lad to keep me up-to-date. There should be lots to show, as they plan on starting boarding out tomorrow! Should start to look like a room.
