Hi,
My Mum lives in a 1960's bungalow with reasonably good insulation , cavity walls and double glazing. She gets a lot of problems with mildew behind cupboards and condensation on aluminium window frames. Two internal walls are single skin but shared with the integral garage, so these walls get colder.
My feeling is that the house does not have adequate ventialtion so was wondering about systems which pump out stale air and pump in fresh air, transferring heat from the former to the latter .
The bungalow has a huge accessible attic space and her kitchen and bathroom both have false ceilings, si I assume any vents could be placed easily out of site.
I took a look at the xpelair site but the range of systems is bewildering. I wonder if :
a) Anyone thinks this is the right approach
b) any experience of the cost and which products are suitable
c) I also have read of systems which create a high air pressure indoors . forcing air out. Is that a better approach ? I assume heat is forced out too !?
