| Insulating a Roof Gap |

How about placing a strip of foil backed bubble wrap insulation over the gap and pinning it to the foam with barbed plastic nails or sticking it with double sided tape? It should be easy enough to do with poles if you divide the length into small segments. |

Well certainly that's a fresh approach I hadn't considered :thumbup: Keep those ideas flowing :beer: |

Why not just use a longer piece of tube to squirt expanding foam? You could use aquarium air line, use some copper pipe which is rigid to thread the tube up. If you can get to both ends then you can secure the tube then pull the copper out. Squirt foam withdrawing the tube as you squirt...simples |

I'm a bit confused here with the "top hat" vent. Is this meant as a permanent vent for the shed? I f so and you really want to close it , can you get up outside and seal it ? |
| awemawson:
Originally built as a cattle shed it needed good top ventilation, I need far less. My machines don't transpire like cows :) Sealing from outside is theoretically possible with squirty foam, but when we did this on a lean too at the side of the barn, it wasn't entirely successful, and over a year or two the foam degraded to an unsightly brown colour. If access up there inside was possible I might try squirty foam, a bit at a time bridging the gap over a few sessions, but trying to bridge that size in one go is asking for it to droop out - been there done that :bugeye: |
