Floorboards question

Howdie. So, we're getting someone to put some rockwool under our boards, then polish them up. He said that he won't need to lift all of them up, but only every other couple (if that makes sense), to slide the rockwool on battons he'll place underneath. Does that make sense?

I'm loath to make a recommendation until after the job is done well, I'll PM you the guy's name in the meantime. We've ended up bringing someone in to do it, although I initially wanted to just hire the sander from that place in Catford. I didn't trust my DIY skills to do the insulation though.

insulated under my kitchen floor but took all boarding off / entire floor up and used solid insulation (which has worked a treat). I nailed batons across the underneath of existing joists and laid the cut insulation across these batons and between the joists after cutting it to correct width. Filled-in any gaps with expanding foam.

From an OCD perspective, I don't see how you can guarantee EVERY gap will be insulated if you do the job without taking up the entire floor, but I'm no expert so perhaps clever people do know a way. For me I wanted no question about coverage and no cold spots.

Taking up every few boards and laying rockwool seems reasonable to me... it doesn't need to be airtight!


Like when you put on a coat on a cold day... it might be warmer if you were in a sealed spacesuit from head to toe, but it still does the job.

    • ??? When they refer to "all Dulwich", I took that to mean including the residents of the streets where the traffic has been directed into due to the LTNs, which are presumably experiencing greater pollution/stress,  whereas the "privileged few" in the LTN areas are experiencing lower pollution due to less traffic. Hence the reference to inequality. Sorry if I've got the terminology wrong.
    • That's interesting, because I thought the Overground would transform Forest Hill, but I don't see much evidence of that. Have I missed it? Can't say I've noticed much change in Penge either though, on the rare occasions I go there 😂 , so maybe I'm just inattentive ....
    • I've not heard of many moving to SE23 from SE22 or choosing SE23 over SE22 in the first place.  Certainly Clapham and other expensive places to the west.  It may be that this is my demographic but there was always a feeling that Forest Hill was rougher, off the beaten track, until the arrival of the Overground changed everything.  But there again the gentrification of Penge is astonishing
    • Much better Restaurant offerings on and around Rye Lane than on Lordship Lane tbh.
