I was thinking on the concrete flooring to use the fiber underlay and the silver one. But do I need to do any damp proofing? can’t see any under the old carpet. I see that the silver underlay has damp proof… but the other silver/gold one don’t as such.
When I put it on if I want to stick both fiber and silver… do I put the fiber first then silver with the sliver side up or down? or do I put the silver then the fiber… again which face is the silver side?? same for upstairs on the wooden board… I assume if you put it the wrong way it can keep the damp in and rot the floorinng? would I need some plywood in between the boarding and the underaly? etc…
Hope someone here can share its wisdowm:) and thanks ina dvance
allways put a vapour barrier down on concrete floors, you can buy underlay that is suitable or you can use builders membrane, it makes laying the first few courses a slippery afair but you don’t want the laminate cupping!
Can’t be ar*ed with the link but it’s all about being sure you’ve got it right. So the damp proof membrane is probably a waste of money but put one in on the ground floor just in case. All in one stuffs o.k., but you can go cheaper using 2 separate layers.
so, DPM then put a soft membrane over the top to stop the whole thing rattling and even out the lumps. Soft foam can be o.k. but firm rubber is better, say 2/3 mm thick.
Fibre board is better for first floors as it talkes out the crappy floor board humps and bumps and acts as a good impact sound deadener. Essential if you have teenaged/early 20’s kids to lessen the friggin music coming through from above.
Check out “Screwfix” stuff for the ground floor. B&Q do the best fibre board deal going on price/quality.
There’s cheaper trade stuff out there but I assume your not doing football pitch areas of this.
:w00t: thats my favourite line, it covers your arse if things go wrong.
seriously though, a quick phonecall to the manufacturer, or even check their website for approved underlays. If you stick to their own recommended spec, then if things go wrong you have a better standing
