Insulated plasterboard for cold wall

lisa701

Since my neighbour built a two storey extension to the side and rear of their property we find our driveway has turned into a wind tunnel. As a result the outside wall nearest to the driveway is really cold. Inside we have always had problems with condensation on the windows in winter but now find this cold wall gets mould forming on it too. The small bedroom is the worst as its on the corner and I suppose more exposed to the elements.

We tried for cavity wall insulation but was turned down by the free deals as they need to erect scaffold over our conservatory which is possible but too much like hard work for them. We cannot afford to pay for it to be done so I'm trying to find an alternative solution.

I really need to get some cupboards fitting into the bedroom but as the last ones went mouldy on the backs I'm reluctant to buy replacements. I was wondering if installing insulated plasterboard along this wall before installing new cupboards would be a solution. Whats your thoughts?

Insulated plasterboard could help solve your problem, but to be honest once you factor in the cost of having it installed and 'finished' to a reasonable standard, your probably better off having the cavity wall insulation installed (and the rest of the house benefits too).

A cheaper alternative to these two options might be to add ventilation in this room (normally a vent high on the wall to allow the humid air to escape)

We already have quite a big air brick in the room which is uncovered plus vents in the windows.

Hubby can do all the installation work so it would only be the cost of the materials. Priced it up and its a fraction of what companies want to charge us for cavity wall insulation. Maybe I can save up and get that done later.

I know solid walls can be susceptible to condensation but I thought cavity walls didn't normally suffer from it.

Have you looked at what you've got that could be releasing moisture/humidity into the house? Is there an extractor fan in the bath/shower, on the cooker etc? Drying washing indoors?
