NO – Increasing the insulation in your home will increase the average temperature and so will make your home feel drier. You will notice that your home will feel drier and dampness in bedrooms, wardrobes etc. will be reduced. Last generation injected wall insulation products included water based foams that sometimes caused very short term moisture issues due to the amount of water they contained at the time of installation. Insulmax is not a water based foam. Cold surfaces, like uninsulated walls, tend to become damp by condensation. Damp walls provide the perfect conditions for mould growth, especially in sheltered areas like the bottom corner of the bedroom wall. Insulating the wall reduces the amount of condensation and the drier wall cannot support the growth of mould.
