    In the spirit of money saving, do we think short lengths of pipe lagging could do the same job? Wedged between felt to keep it separated - I imagine you could stick a cut in the top to allow it slot onto the felt to stop it falling through. 
    Like this?

    Exactly that yes! Should save money on plastic vents if you've already got it lying about the garage/shed. Even if it's a temporary measure.

    I've actually done this at the moment as a stop gap, my concern is over time they will get condensed but for now I have cut them into 1 inch discs and put 2-3 in a few of the gaps, but don't think they're as good as holding them open 

    My felt isnt as loose as the image above so I wouldnt be able to get them in like stuart45 has. I'd imagine if it was that loose I probably wouldnt need the  lap vents!

    I would suspect the airflow is slightly higher with the plastic vents than the tubing, if only because there's a wider surface area through which the air can flow. But otherwise probably does a similar thing

    Well my 10 vents installed today, seemed to have a bit less condensation when I went up so I am hoping that the foam rolls had started to have an effect. Going to get another 20 of these vents ordered I think and just have a good distribution around each face of the roof.

    I also got some loft lids and have so far placed them on top of each light but not done the sealing part yet.

    We installed these vents earlier this year they were amazing did the job and we haven't had any condensation in the loft since.

    We noticed an issue when mould starting showing on my bedroom ceiling and I thought out tank was leaking!.

    Was quick tho as week before the loft had been dry.

    Where are you sourcing them Ashe? I think the problem must be widespread with recent weather as the ones on Amazon have gone up to £40 for 10, I'm sure they were £25 a few days ago. Ashbrooke Roofing have sold out of theirs.

    It's another company selling them at £40

    at that price I'd probably just buy some plastic
    corrugated Roof sheeting and cut it up with a multi tool and drill some holes in it for extra airflow 

    I can just about handle paying £2, although when in hand feels very overpriced but you're paying the fee for something that is in demand this time of year I guess 

    probably good money in getting something made up and a few thousand units produced and selling them next winter
