Hi Folks,
I live in a house built in the 1960s it does from what I see have Cavity Wall Insulation but still outside walls are generally colder to touch than their inner counterparts.
On the outside wall I get around 12 - 13 degrees where as on an inside wall I get around 18 - 19 degrees
I have an infared thermometer.
Currently the walls appear to have been plastered and painted in some areas.
So I am wondering if I can buy Kingspan Kool Therm K18 and screw it directly onto the existing wall? Or should I build battens and screw it onto the battens.
Will this be concern for damp - Presently the room does not experience damp?
The wall in question is 7 feet wide by 7.5 high
So I guess I need 3 boards of 2100 x 1200
