Working method for insulating sloped roof in garage

[jbak]

Hello, planning to insulate my garage roof

Approx. 2.7m at the eaves and 5m at the ridge (4.5m underside of the glulam beam)
The length is about 8 meters.

What's the best way to do this workwise?

Scaffolding (I have a haki), rolling scaffolding, or rent a scissor lift?

The work involves installing boards for ventilation against the outer roof, plastic sheeting, and installing battens.
The plan is then to fill with loose-fill insulation from a company.

Grateful for tips on scaffolding placement, etc., so you don't have to move the scaffolding too many times.

Borrow a hakihjul and drive around a section of scaffolding if the floor is relatively clear, it becomes a good work platform to work from.

Would work, good idea.
When covering with plastic, maybe you need to be in at least 2 places at the same time and stretch it to avoid unnecessary joints along the length 🤔
Need to think a bit more.

Measure 250 cm from the ridge at the gables and strike a line between them. Then follow the line with the plastic edge and staple along the roof, before working downwards and tightening the plastic.

Sounds like a reasonable method, will need another layer of plastic upwards later, but hopefully that will be enough, it's 2.7m wide if I remember correctly?

Too bad you didn't place a strip of plastic on the ridge beam before the rafters, it makes it a bit easier when it needs to be taped together at the ridge.

I understand what you mean
I guess you can tape against the laminated beam and then fix it with battens that lock the plastic, I think?

I understand what you mean
I suppose you could tape against the laminated beam and then secure with furring strips that lock the plastic in place, I think?

Alternatively, place a piece of plastic in each roof truss section over the laminated beam and tape it together with the plastic downwards on each side
