The parts people forget and drive back for
None of these is the main material and every one of them changes whether the job works. Baffles keep the soffit vents breathing, depth markers are the only way to know you hit the R-value you paid for, and walk boards are what stops a foot going through the ceiling below.

Start with these 4
See everything →The four that decide whether the finished job performs the way the calculation said.
Insulation depth markers
Blown insulation looks even when it is not. This is the only practical way to confirm the depth.
Plywood walk boards
Spreads your weight across the joists. Stepping through a ceiling is a common and expensive mistake.
Insulation support rods
Batts hanging an inch below the subfloor do almost nothing. This is why crawl-space batts fail.
Access and walkability
Heavy-duty extension cord
Attics and crawl spaces rarely have an outlet. Rated for the blower if you are renting one — an undersized cord is a fire risk, not just an inconvenience.

Fixing and finishing
Staples
Matched to your gun. Running out mid-wall is the usual way to lose an hour.
- Finishing
Drill and driver bit set
Covers the fixings the job actually uses rather than the two you own.
- Finishing
Ground liner pins
Hold the liner flat to the ground while you tape the laps. Without them it creeps as you work across it and the laps you taped yesterday have opened by today.
- Finishing
Contractor trash bags
Heavy enough for insulation offcuts and old material without splitting on the way down the ladder.

Safety gearFibreglass and attic dust are a genuine respiratory hazard. A respirator, sealed goggles and gloves belong on every project, whatever you are insulating.10 items
Measuring toolsGetting the area and the existing depth right is what decides whether the rest of the estimate means anything. Tape, laser, depth markers, moisture meter.23 items
Air sealingDo this before the insulation goes down. Afterwards the gaps are unreachable, and insulation over an unsealed ceiling underperforms badly.12 items
