Cold rooms.

I've got 2 rooms in the house that are really cold, even when the heating is on and the rest of the house is fairly warm.
The property is a 2004 built , 3 storey at the front and 2 storey at the back.
The ground floor at the front has a garage and a bedroom, and no surprise it's the bedroom and the room above the garage that are the cold rooms.

The floor of the bedroom is concrete and has some thick underlay and a thick carpet, i've drawn the layout and some ideas (in red) that i'm thinking of doing to help the downstairs bedroom - anyone know if these are a good idea and worth doing or am i just wasting my time/money with them. Also is it worth changing the radiator for a double bank one ?

For the room above the garage I was thinking of either ripping up the floorboarding and see if I can stuff some insulation in the void or put a false roof in the garage say 6inch void and stuff that full of insulation or even both.

Not sure if the cavity walls are filled, with house built in 2004 I would have expected so but will get someone out to drill a test hole to check.

    For the room above the garage, I would definitely take the floorboards up and have a look. In ours we had holes to the garage for cables to the consumer unit, and holes for the pipes to the boiler - in both cases, they were far bigger than they needed to be and letting in cold air from the garage. We also had gaps at the sides of the joists making the floor void open to the cavity - these were sealed with decorator's caulk.

    I'm not sure of the best approach to the garage wall, but the insulated plasterboard idea looks reasonable, although if it is a cavity wall, you could be wasting your time as the cavity is likely to be draughty.

    A simple, but small improvement to both is to insulate and draught-proof the garage door. We just put a brush draught excluder along the bottom edge, and stuck polystyrene to the inside. The garage is noticeably less cold although not really "warm".

    HTH, Brian.

    Room over garage : I think that you will have chipboard flooring - I may be wrong - and that trying to take this up will be messy ( if I am right the chipboard will be glued along the joints ). Your solution to insulate from underneath would be the one that I would go for - this would be non-destructive and you could look at some of the high performance insulation products such as super foil quilt (thickness 40mm approx).
    Forgotten but not gone.
