Slightly cold room - possible to insulate internal walls?

NIMAN

I have one room downstairs that seems slightly colder than the rest of the house (not dramatically colder, but you notice the difference).

Its at one corner of the house, so has 2 walls interfacing with the outside.

Is it possible to add anything to these 2 walls to help with the heat of the room?Is there any form of insulation I could have applied and then decorated over?

Yes, there are options:)

What are your walls made of? Concrete block stone etc age? Cavity wall or solid construction? Any damp issues etc?

Bryan F would be the one to advice suitable materials:D

We have solid concrete block walls and used kingspan insulated plasterboards and it makes a difference to heat loss. We only used the 38mm insulation and 12mm plasterboard version. I would of gone thicker but the bedrooms aren't huge.

We haven't had any problems with condensation and our walls were very dry to start with.

No damp in the room.

The house is smooth rendered plaster, so assume standard build underneath. I'm not original owner.

Think its approx 10yrs old.

I would want know why one room is colder than the others before insulating. the next thing is what kind of budget are you willing to spend to improve your families thermal comfort.

as SF says above -cheap and cheerful insulated plasterboard is an option, but really only a remedial option for one room IMHO. if you can afford it look at the whole house considering external wall insulation,windows and air-tightness in the mix.

Is the house 10 years old or you have owned it for 10 years?

If the house is 10 years old it will probably have a cavity wall construction. If this is the case you may be able to have it filled if not already filled.

If you have a standard 4 inch cavity and 4 inch blockwork either side then your wall will be around 13.5 inches thick providing the wall isn't drylined inside. Tap the outer walls inside and if hollow then drylined.

A photo of the house may help.

I would get an insulation company in to advice on the options.

Its approx 10yr old, I've owned it for a couple, so I guess you are correct in your assumption about its build.

I had thought about getting the cavity wall pumped, may look into that again. Is there still grants available for it (I know the solar grant has been cut recently)?

Double-sided foil-back with plasterboard sounds good for the internal wall. It comes in 4 depths. I think it's a Kingspan product. For external wall infill, there's silver-bead or expanding foam.
