Carpeting above mosaic tiles

snout71

My hallway has a fantastic mosaic flooring, problem is that it is so cold I will need to insulate and carpet on top of it. Unfortunately there is no way of insulating underneath the suspended floorboards to insulate from underneath.
so the question is how do I go about insulating from above?
my guess is that I’ll need some vinyl or foil underlay then some plywood (so the underlay and carpet can be nailed on top.
than you in advance

If you love and are lucky enough to have these tiles would you consider having a temporary carpeting for winter so you can take it up and enjoy the tiles the rest of the year.

Bit of a pfaff if it's large - but I've done this with my small en suite so my delicate little feet don't get frozen in winter and it can be taken up and cleaned etc.

Tis different with a hall I know.

Beautiful rugs? Or is it beyond that?

A good quality underlay and carpet will act as good insulators on their own. I would not think it was really worth putting any extra insulation in, unless you really want a belt and braces job.

I'd consider a carpet runner, so you can still see the mosaic at the sides, rather than covering it up completely 

Or, a good pair of real sheepskin slippers. Which is probably the cheapest option.

In my lounge (a suspended wooden floor), I covered the area with Baco Foil (the wide stuff used for wrapping up the Christmas turkey) followed by a layer of 5mm woodfibre laminate underlay. After screwing down gripper rods, 11mm foam underlay was put down, and then a carpet. This stopped all those nasty cold draughts coming up through gaps in the floorboards and made the room much warmer as a result.

With a tiled floor, I'd advise against screwing or nailing down gripper rods - A grab adhesive would do less damage. 8-10mm of underlay would provide some insulation as would any carpet.

When budgeting for this work take into account you may need to get doors altered(shaved) to accommodate the insulation and carpet.

I’m currently more concerned with the heat loss than losing the view of the tiles. Looking at getting a heat pump to reduce bills, but with the lower running temperature of gas and the drought through the uninsulated floorboards I really need to cover it over
the sub floor does have air bricks but I am a little concerned about placing foil over the tiles and possibly the other rooms floorboards because of moisture.
