Below are some pictures showing the internal
insulation and framing taking shape in the back extension of Bridge Cottage. The
floor and walls are insulated, and frames are created for the floating floor.
Finally stud work is put in against the walls, ready for
plasterboard.
This picture shows the insulation being installed, along
with the frame for the floor. I'm using 50mm Kingspan insulation on the walls,
and 70mm Kinspan on the floor. All the framing uses treated C16 70x45mm
timber.
Where there will be stud walls I have added extra
bracing in the floor to carry the new wall weight. The gaps between the frames
are then filled with the insulation sheets, and the joints sealed with foam and
taped using aluminium foil tape.
This picture shows part of the completed floor, with the
frame and Kingspan insulation visible. The chipboard is only fixed at the
perimeter, and where the new walls well be.
Here is a picture of the completed floor, looking
towards what will be the new bathroom and kitchen. The Kingspan currently is not
held against the wall, but when the timber stud work goes up, that should help
fix it in place.
Getting the new floor down was momentous. But this was a
major milestone - the first piece of plasterboard goes up on the ceiling. I'm
using 12.5mm TE plasterboard, fixed using 30mm screws.
More boards going up. We managed to get the whole
ceiling covered in just one day - this took about 10 sheets, with a bit of
cutting required to make them fit. This is the only drawback with renovation -
nothing is square.
The
completed ceiling - ready to be taped and finished. Now the wall framing can go
in...
Here the stud framing is going up. The studwork is fixed
between the floor and ceiling - there is no connection to the outside walls.
This allows the insulation to be continuous, so there shouldn't be any cold
bridges. The studwork is all using 70mm x 50mm treated timber. The studs are set
at 600mm centres.
Putting the studs on their side creates a 50mm space
between the insulation and plasterboard. This will be used to run services, such
as pipe work and cables. All the joints between the insulation boards have been
sealed using expanding foam, and then aluminium foil tape. This creates a vapour
barrier, as required by Building Control.
We
also needed to add extra framing around the doors and windows, which the
plasterboard will fix to.
The
front wall being framed...
We
are not the tidiest workers in the world! This is the back kitchen wall
insulated and framed. Just noggins to go in...
I
had temporarily fixed the fuse box to the porch wall. Since it was now time for
this to be lined I had to move the fuse box. Best place - propped against the
wall.....
Here is the back porch virtually finished off. Because
of space I have lined this room differently - the frame is against the wall, and
the insulation is between the studs. I also needed to install a damp proof
membrane above the concrete floor and part way up the walls, as this floor had
been built without one.
