Cheapest do-it-yourself insulation of walls – retrospective.mp4
– Do it yourself insulation for walls of existing houses, using fibreglass (either recycled or new)
– IF POSS SCROUNGE SOME USED INSULATION as it’s much cheaper.
– SCROUNGE/buy some thin slats of wood, e.g. old trellis, because you’ll need one or two 20cm bits per hole you cut in the wall (you screw the round piece into those bits of trellis)
– SCROUNGE/buy screws about 3cm long. Two to four per hole.
– DUST COVER OR REMOVE EVERYTHING to minimise tedious dusting.
– DRESS LIKE AN ASTRONAUT to prevent deadly choking on dust, rashes,
– DRILL/JIGSAWall the wall cutouts, LABELLINGthem 1,2,3 on both the cutout & the wall, for easy finding.
– SAND their, and wall hole, edges smooth for easier sealing later.
– DRILL holes in the cutouts and in the walls (either side of each cutout, for securing the sticks), and COUNTERSINK so screws will all be buried a bit. SAND all those holes flat too.
– STUFF IN the insulation, not hard-tight, but leaving no spaces for heat to drain through – can can cause 30% loss of efficiency for that void.
– INSTALL ALL THE TRELLIS STICKS behind the cutout hole. SCREW through the wall into the sticks.
– INSTALL INSERT THE HOLE CUTOUTS into their original places and SCREW through them into the trellis wood stick, so they’re fixed in place.
– Use porridge-gooeyness PLASTER to fill all the cracks.
– SAND and PAINT.
