New vinyl flooring in kitchen...........

[Smiffy]

DIY numpty chops again looking for a bit of advice.
Having new sheet vinyl laid in the kitchen. The floorboards in the kitchen had been covered with hardboard before the existing vinyl was put down, but we are replacing this with 6mm ply as some of the hardboard was in a bit of a state.
Under the kitchen floor we have a small cellar, and the kitchen can get quite cold during the winter months.
Would it be worth installing some to the foil backed stuff you can buy on a roll on the floorboards before installing the ply, or could this cause problems in the future????
This is the sort of stuff I mean....

Thanks for input and apologise if this is a stupid question, but like I say I'm clueless.

If you can get access to your cellar, I'd suggest putting some proper insulation in.

The PIR board comes in 8x4 and is easily cut with a saw. Measure distance between each joist, cut it, slot it in and Bob's my uncle?

Cheers Stu. You are my favourite nephew...???

Don’t forget to take all aspects of the new flooring under any appliances you have in the kitchen. It won’t be the engineers fault if you don’t and the flooring tears when an appliance is removed from its location to be worked on.

Keep a can of WD40 in the kitchen. once the new flooring is down, WD40 is excellent at easing the friction between appliance feet and the vinyl including removal of the black rubber marks some feet leave behind.

I've always used a little squirt of slippery washing up liquid ???

This is your best bet. What is the thickness of the floor joists when viewed from the cellar?

This is the sort of thing you will be faced with but he's making it look more difficult than it is.

It may be easier (but more expensive) to use multiple thicknesses of thinner boards (4 x 25mm rather than 100mm)

Worth sticking an underfloor heating mat down once it's insulated ?

It makes more mess and is harder to clean up compared to WD40. Trust me

This is exactly what I did simple job and makes a big difference ?
