Hello

We live in a semi D . The front and side walls are cavity walls, The back wall is built with Cavity Brick ( I think) & dry lined approx 13" deep , I have checked wall vents . Is it worth my while upgrading insulation in the cavity walls, and not improving insulation on back wall , as external insualtion is very expensive, i hear .

Any one know

Regards
 
Any extra insulation is worth doing imho. I'm actually thinking of getting cavity wall insulated on the front of my house as their seems to be a lot of air getting in from that area. I'm thinking of the white beads of polystyrene or whatever its called being pumped in.

Anyone know is it expensive to get done.
