Hello
My 1st time on here, so be gentle with me!
Re: two ground floor rooms in a 200 year old cottage, I'd like to lay 16mm floorboards over the existing floorboards and varnish them. One room has the original joists and 28mm floorboards with bare earth below. The other has been recently renewed with 20mm floorboards on brick/timber plinths over a DPM & concrete screed.
Why not just sand the existing floorboards? Aesthetics (some of the boards aren't great), but mainly because I want to add an extra layer of timber for insulation - this is Scotland after all! Surely this would be more effective than doing what I've already done elsewhere i.e. filling floorboard gaps with papier mache/flexible sealant.
I would like to enhance this by adding a thin layer of insulation/underlay sandwiched between the 2 layers of floorboards. But what (if anything?)
I assume it would need to be breathable (e.g. fibreboard?), but I am confused about the difference between laying floorboards above floorboards rather than, say, "natural wood laminate" for which all manner of underlays are recommended.
Any advice appreciated. Thanks.
