Sonic Gold 5mm Pro Underlay
Transform your home with luxurious warmth and comfort
Sonic Gold 5mm Pro Underlay provides unparalleled noise reduction, moisture protection, and thermal insulation for laminate and wood flooring.
With an impressive thickness of 5mm, Sonic Gold absorbs impact noise and minimises sound transfer between floors. The dense structure dampens footsteps, provides cushioning, and reduces flooring noise by 22db. This allows you to enjoy quiet tranquillity in high traffic areas.
The integrated plastic moisture barrier shields against dampness and spills up to 75% relative humidity. No more worries about moisture seeping into the subfloor and damaging flooring in kitchens, bathrooms, basements or seasonal rooms.
Sonic Gold also excels at retaining heat, transforming cold hard floors into cosy spaces. The exceptional 0.9 tog rating keeps rooms warmer in winter and cooler in summer for year-round comfort.
Experience luxury underfoot with Sonic Gold. Transform any space into a peaceful oasis with superior noise reduction, unrivalled moisture protection, and indulgent warmth. Your floors will thank you.
Acclimatisation
Allow your flooring to acclimatise in the room where it will be installed for at least 48 hours before fitting. Keep packs sealed and lay them flat.

Decent underlay for the price
Used this under 8mm laminate in a spare bedroom. Does a reasonable job of cushioning and cutting down noise. Wouldn't say it's anything special but for the money it's absolutely fine — wouldn't hesitate to use it again in a low-traffic room.

Penthouse white oak flooring
We have just laid the flooring and it looks great you cannot fault it the only problem we had with floor debot was the communication we ordered 13 packs and only 10 was delivered it took us ages to get any reply about delivering the other 3 packs it was only when we emailed Paul that we got somewhere and to be fair he sorted it out for us I’d like to thank Paul for that end of the day we are happy with this flooring it looks great
Ms W
Laminate flooring and underlay . Good service.
Great product at Great price
I did quite a bit of research for the right product at a competitive price. Floor Depot stocked the item I wanted and it was the lowest price I could find anywhere.
