Ever thighter building regulations are increasing thermal standards, the focus being on reducing CO2 emissions.
Viable options for upgrading wall insulation has not generally been justifiable, financially, except when done with substantial renovations.
Whenever insulation is upgraded, it is important to avoid creating circumstances where interstitial condensation may occur. This could lead to timber decay.
