I can get vents in the soffit and some holes in the gable walls each end but was wondering if the felt overlaps could be `opened up` to increase ventilation,using the gap formed by counterbattens ?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300028#Comment_300028 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300028#Comment_300028 Tue, 31 Jan 2023 20:15:24 +0000 kebl2825 In my situation I've found lack of sag in the felt and/or narrow rafter centres hindered me adding as many felt lap vents as I originally intended to (was aiming for whatever the building regs approved doc said the recommended free area was at the time) but anecdotally at least those I have added certainly seem to have increased the overall ventilation sufficiently - I've not witnessed any condensation form on the underside of the felt since, which had been a problem a few winters ago.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300029#Comment_300029 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300029#Comment_300029 Tue, 31 Jan 2023 20:25:46 +0000 kebl2825 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300030#Comment_300030 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17726&Focus=300030#Comment_300030 Tue, 31 Jan 2023 21:23:10 +0000 chrisinbrighton
