My shed being roofed with corrugated bituminous sheet, and being used for, a work shop and frost free storage, needed the roof insulating, this us how I went about it. I've got a part written instructable on building the shed, but I thought a short one on something relevant to the season might be of more interest
Step 1: Materials and Tools.
Glass fiber insulation, scaffold netting, also sold as shade netting, garden twine. Corrugated plastic sheet for lining, a woven PVC/polypropylene tarp would do, hardboard or plasterboard would be better
A stacking needle, a sharp knife, and a staple gun.
Dust mask and rubber gloves, full boiler suit optional, the fiber glass insulation releases fine particles of glass these can make you itch and are not too good to breath in in any quantity, hence the last step of covering in.
Step 2: Cut to Size
Scaffold netting is a lose woven fine plastic mesh used to stop debris falling off scaffolding, it is also used in gardening to shade green houses and make cages to keep butterflies off cabbage crops. It typically comes in 2m wide sheets on a 50m roll(sold by the meter in some garden centers, can sometimes be scrounged from building sites along with the protection sheet as it tends to end up in a skip at the end of the job) it tends to have an easy cut seam down the middle making it easy to cut into 1m wide panels. My netting had previously been used as a screen for a fruit cage to keep birds off and was already cut into 2m lengths I just had to split it down the seam.
The fiberglass insulation has a nominal 10cm thickness, and was pre-cut into rolls to go between rafters at a standard 40cm spacing it cuts easily to length (or if not pre-cut into strips the roll can be sliced into strips whilst still rolled in its plastic packing) with a sharp knife. A 1m wide strip of netting is enough to completely enclose a strip 40cm wide 10cn thick strip of insulation wool
Step 3: Wrap and Stitch
I placed the length of insulation in the middle of the netting and brought the edges up over the top of the insulation.
Then used the sacking needle and twine to stitch the edges together, with long stitches about the length of the needle. The twine is intended to feed freely from the center of the roll, this mean the roll can be left at one end whilst the seam is stitched then cut, instead of having to cut a 2 m length of twine
The now enclosed insulation is now much easier to handle.
Step 4: Fit Between Raffters
The enclosed insulation can now be fitted between the rafters stitched seam upward and held in place by stapling through the netting into the rafters
Step 5: Line
I could have left it at that, but having acquired a couple of sheets of thin corrugated plastic, sold for site protection,(heavy duty dust sheets where you need to go through a carpeted area withe wheel barrows etc) I cut this to fit the ceiling of the shed and stapled it into position, hardboard or plasterboard,would have been better, but can be fitted later without removing the plastic
