Hi all
The (external) build for my summerhouse is nearly complete and I am looking to move the build to the interior including insulation.
The summerhouse is of similar design to the one in the picture ( apologies to the original poster whose photo this is, hope you dont mind me borrowing it) but the roof joists are 6x 2
The idea is top ut 100mm pir in between the joists leaving a 25-30mm gap.
I presume it needs ventilation.
I want to box in the overhang with the T&G I have clad the shed with. and presume I should leave a ventilation gap.
Logic (to me) dictates the gap should be on the facing edge (marked in red) but I wondered if i could leave a gap on the downward facing edge( marked in blue)
The pir will end on the inside of the summmerhouse.
There will be a ventilation slot at the back in the same position as the red mark at the front.
Any Thoughts?
Thanks
