In this day of saving energy, most properties are now becoming draught-proof. This, in itself, is causing problems.
Condensation occurs when vapour is cooled and compressed to its saturation limit. When properties have had double glazing, insulation, better fitted doors, etc., there is nowhere for this cooled vapour to go and so it will settle on solid structures, causing damp and eventually, black spot mould, wet rot and corrosion.
Mould can cause watery, itchy eyes, chronic cough, headache or migraines, difficulty with breathing, rashes, tiredness, sinus problems, nasal problems and frequent sneezing.
Rather than making your problems less frequent by means of air or window vents, a new and proven installation of a PAM PIV Unit will eradicate air condensation problems in a very short time.
