Neverfinished

Hi, IGP. I came across your recent post & photo just now. I've just joined Buildhub with a question 'Laying hardwood floor over suspended floor joists; would any underlayment help?' Your posts & responders have helped answer my question to an extent, so thanks. I've paid £1700 for new floor planks to cover a room similar size as in yr photo & don't want them to rot, want optimum insulation too. Found the article in the thread - 'Best Practice Approach To Insulating Suspended Timber Floors' really helpful & plan to follow it. Sounds expensive though! I attach a photo showing what I'm doing. Will wrap it with the appropriate membrane(s) but leave the insulation @ current 80mm as concerned to keep the joists breathing in part at least. Got the fireplace & hearth to upgrade too. Cheers, Steve/Neverfinished

Hi, I'm about to begin lifting the original 'pine' planks flooring in my victorian terrace home. Then to lay American Ash (19Depth x 138mmWidth) planks, & I could just lay them again straight on the joists as originally. Being on the ground floor, there's the typical 3ft 6in ish 'crawl space' beneath, which has a well designed 'air-draught' thru; And at base just the original reasonably dry soil within brick foundations. See photo attached. I've added 80mm of Celotex between the joists several years ago. Original planks survived fairly well in the environment just described though had cupped, doubtless a long time ago, & had been 'face nailed'; I'm thinking I'd secret nailing this time thru groove in T & G might minimise cuping this time? Would my new floor also benefit from 'shielding' from the elements, especially water vapour, down in that under-space? Perhaps I lay a 6mm plywood base ? &/or lay a Tyveck type breather membrane, on the joists ? I've been a decorating, some carpentry, tradesman for years. I'd much appreciate anybody's ideas / suggestions before I start. Thanks in anticipation !
