Our loft serves a dual-purpose. As well as for storage, I use it as a big-boy's playroom. The floor area is boarded, with insulation beneath.
We are in an exposed location, and south-west facing, so anything more than a gentle breeze can seem like a gale. I would like to, somehow, stop the draughts that come in through the eaves.
I'm not particularly bothered about heating the space for the amount of time I spend in there, so I feel that 100+mm of PIR is going to be overkill. Will a 25mm thickness of PIR overlaid on the rafters, taped at the joints, and expanding foam where the PIR meets the walls and floor (it's a mid-terrace house), be sufficient to cut the draughts to a minimum?
All comments/suggestions welcome.
TIA
