hi all
i wish to improve the insulation in my loft but need to ask a few questions before i actually start the job,
i will be either re-doing the between joist insulation or topping it up. currently i have the shredded paper style stuff and was originally thinking of adding 100mm roll type? would this be ok to do or should i remove the whole lot and replace completely?
i want to add some insulation in between the rafters but i am not totally sure how to do this without affecting the ventilation. am i correct in saying i need to leave a 50mm gap between any insulation i add and the felt that is behind my tiles when adding insulation between my rafters? and would i also be correct in saying i can either add an insulation to the rafters with either a vapour barrier attached or use vapour barrier sheets stapled to the underside of the rafters over the insulation?
im asking all these questions as i dont want to introduce a condensation problem to my loft but want to up its insulation properties
many thanks for your time
