Taping up the insulation

Five minutes in and I'm already bleeding, what a familiar sight this is becoming. This time, it was changing the blade on the Stanley knife. A worthwhile injury, as I found a new blade every now and again makes the knife slice through the foil nicely. The blade goes through the foil great, that's not the problem. The problem is the polyester webbing inside. It's like the poly stuffing used in cheap pillows and most kids fluffy toys. It doesn't cut with a knife, it pulls along with it. But with there being multiple layers of foil then web, I can't afford to keep switching between knives and scissors

You can see I tried quite a few pairs of scissors. They need to be the big ones you use to chop up credit cards and open those plastic blister packs that are impossible to open any other way

The tape is good, but if I was doing this again on a more critical area (like inside the house), spray a line of low expansion foam under the foil along the seams to make sure they grab real airtight. The tape doesn't like taking corners and tends to tear. Also, the foil is full of lumps and bumps that create turns the tape isn't so happy with. When I batten the seams, I'll try running some LE foam or silicon on the mating surfaces. Only thing I'd be careful of is using foam, letting it cure and then finding the timbers have too many lumps on them for you to get the battens on. Not only will extra sealing keep drafts out, which I'm not so bothered about in an external room, it'll keep all the wildlife from making nests on the ceiling. MR SPIDER! I'm looking at you! And there's eight times as many of me through your view of things, so get out

I'm hanging on to all the off cuts, I thinking about using them as stuffing around the hot water cylinders to add some extra U value. No point binning it and loosing heat when this is essentially free now

Shouldn't have used parcel tape as masking, and it was only on there eight hours. No problem, acetone to the rescue

Foaming up one of the bigger holes. Incidentally, now that most of the roof is foiled, I can really feel the drafts coming through around the seams, impressing on me the importance of the tape

The battens were out in the timber and my yard, getting rained on. If I screw them up now they'll shrink as they dry and be more likely to warp. Also, I really don't want to do anymore ladder balancing tonight, my arms are sore from having them over my head the last two days

A real tricky area to reach, there's no where for me to support the ladder and it's right in the middle of the room at a high spot. And... I need to do some drastic trimming

Rubble coming to the surface as the lighter material is washed down. I'll rake up the rubble when the sun gets a chance to dry it out

Luckily, the roofers left the ladders here before permanently retiring, and I can reach it with this really long one wedged against two walls. Still, it's like being on a trampoline

Yikes

The last piece of essential tape going on. I still have some spare and might go over it again to get it all looking tidy

The amount of light the white walls and silver ceiling are reflecting is awesome, I love it

Tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape, tape

The idiot child in kitty confinement. He's in there until he licks that white emulsion off his tail, it could be rabies
