Flooring and Acoustics in Mass Timber Affordable Housing

Hello,

We have a mass timber purpose-built rental project specifying flooring at the moment and are trying to find a healthy flooring option while managing acoustics with CLT floorslabs. We don't typically spec vinyl flooring due to the health concerns around PVC, but the project is budget-conscious, and our flooring supplier is suggesting that all they can offer that meets acoustic requirements is Floorscore certified LVT (with backing).

Does anyone have non-PVC flooring solutions that allow for Code compliant acoustics when combined with CLT slabs? Particularly for affordable housing projects.

Thanks all!

Your best bet for avoiding vinyl flooring is typically linoleum.  You can also go for a non-tire-derived rubber flooring product - you want to avoid the Styrene in the Styrene Butadiene Rubber (SBR) that comes from tire-derived products.  There are also products made from polyester, polypropylene and polyurethane that all good options for avoid vinyl.
  • Linoleum:  Forbo and Tarkett both have good options.
  • Rubber:  Nora, American Biltrite, Johnsonite/Tarkett, Mohawk and Expanko all have options here.
  • Other polymers:  Mohawk, Armstrong, Inhaus Surfaces, Handsome Plastics, Hallmark Floors, Congoleum, Mannington Mills, Teknoflor and Shaw.
Hallmark floors Voyager PVC-free flooring, Mannington Mills Cirro, Congoleum Cleo and Mohawk Pivot Point are all products that look like LVT and are PVC free. And there are acoustic underlayments available for use with any resilient or hard surface flooring products that can resolve acoustic issues.  Pliteq GenieMat RST is a decent product, although it is made of tire-derived recycled rubber, so I am breaking my own rule, but a girl's gotta manage sound. None of this answers the cost issue though.  We used to be able to fight VCT with the maintenance savings, but the LVT's don't need the waxing and stripping that VCT required, so that probably won't work here. I don't know what the cost comparisons are for those products, but that would give you some alternatives to the dreaded LVT. Good luck!

Thanks Anne, Yes, we typically consider Linoleum and there are a couple bio based flooring options we like, but are running into the acoustics issue specifically looking for underlayment that combines with those options to creat the dampening we need for CLT. According the the acoustics and flooring team it’s because the other options don’t have the rigidity that LVT has. Thanks for the suggestions! I’ll dig into those a bit. We are a 100% wood firm so it’s interesting that this is still a problem, but I think it’s a combo of budget and mass timber rather than low rise affordable housing where we can use linoleum or a bio based alternative and get dampening through the floor assembly. CLT is a bit restrictive that way! Best, H Get Outlook for iOS __________
