Insulated underlay for LVT

[RichD1]

I'd like to lay LVT in our sun room. It's previously been carpeted but as there is direct access to the garden it gets abused. The sun room is an old extension with no insulation in the concrete floor so I'm after the best insulated underlay. The floor does not appear to suffer from damp.

I've been looking at 5mm fibreboard but is this a suitable underlay for LVT. I only have a max height of around 15mm to work due to several connecting floors and a patio door.

I guess 5mm LVT is less forgiving for out of flat floors so would an engineered 12mm to 15mm thickness wood laminate be better. Would this also provide a better insulation.

5mm of any insulation on a floor will do precisely nothing.

If you want something durable, then it's ceramic tiles.

LVT and all other crap plastic flooring will fade due to the sun, laminate will do the same and as an added bonus will shrink/expand and disintegrate when it inevitably gets wet from people entering from the garden.

Ceramic tiles though durable is not going to make it any warmer, I think the opposite will apply. We have carpet in there at the moment and that fades.

No issues with wet from people entering as there is a utility door at the side which goes to the garden. The patio doors lead on to a patio only.

I'm now thinking of using 14mm engineered wood. This should provide a better degree of insulation plus a quality foil underlay. Fade can be controlled by using a UV oil or lacquer.

A conservatory environment will be very harsh on Engineered Wood even if it's UV oiled.

LVT will be fine if a glue down system is uesd with a high temperature adhesive, avoid click LVT in such an area.

Ceramics or Stone best for appearance retention but like a freezer in winter.

Quality Laminate like Quick step would be fine, similar warmth to LVT when fitted.

Its not exactly a conservatory it's more a family room with a tiled roof running across the back of the house with small bifold and a window facing the patio.

I have some Moduleo click LVT fitted in my kitchen and hall. It has its own built in underlay.

How much height buildup can you withstand?

 

[RichD1]

About 18mm at max

Are you averse to removing the existing concrete?

I had considered this but I can't print what my wife thought about it.

The ground floor is virtually open plan with lounge, kitchen and utility all leading off this family room. Plus access to the back garden is via the utility room.

Cheapest solution to that problem would be to open easyJet.com and hand her your laptop and credit card
