ᐅ Is it possible to glue down click-lock vinyl flooring as well?

Hello,
we are looking for a flooring solution for the hallway and living areas that is free of harmful substances and came across green vinyl or similar options, which are only available as click-lock planks. However, we want to avoid the unpleasant, loud “laminate noise” and would prefer to glue the flooring down instead, also for durability and to prevent deformation when exposed to sunlight.

My question is whether it is possible to glue down a click-lock floor like this? Manufacturers generally say no—should this definitely be avoided? What kind of damage could occur? Glue-down vinyl floors are usually flexible planks without a click-lock system, but those often still emit some kind of VOCs.
We do not have underfloor heating and would be gluing the floor directly onto screed.

Why are you concerned about off-gassing harmful substances from the vinyl planks, but not about those in the adhesive?

Of course, the adhesive also emits, but apparently, there are low-emission options available. I think the less overall emissions, the better. However, I am not an expert and can only rely on independent certifications. Unfortunately, I do not know the exact emission amounts of the individual components.

I can’t back this up with facts, but my gut feeling about these “Green Vinyl” floors is that they’re somewhat misleading. All those buzzwords they throw around aren’t protected. Some regular (modern) branded vinyl floors, unlike the PVC from the 1970s, already offer these features. I’m also somewhat skeptical of certifications like the Blue Angel. Greenwashing is everywhere right now, from milk cartons to flooring. What’s not clear to me is what these green floors really offer in a tangible way that sets them apart from conventional products.

As I understand it, one of the advantages of green floors is the click installation system, which allows you to avoid using adhesive. But if you’re going to glue that stuff down anyway, then I don’t think the extra cost for “green” flooring is worth it. Although, as I said, I believe you can probably save that extra expense either way.

I trust products with the Blue Angel certification. You are never 100% safe, but this way you can avoid the obvious and well-known harmful substances. It’s better to have a certification than to rely on marketing gimmicks like “Green Vinyl” printed on the packaging instead of just “Vinyl.”

I once watched a very critical documentary about certification, so since then I’ve been a bit skeptical.

But other vinyl flooring products from reputable brands also have the Blue Angel. That’s what I mean. Green Vinyl is probably just a marketing gimmick. I quickly looked up our old vinyl flooring (Viva Floors); they also advertise as "free from harmful substances, phthalate-free, 100% recyclable" and with some kind of international environmental label.
