It's strange how we all have "markers" in our year - in this case, we feel that Bonfire Night marks the arrival of winter. Yes, the time of "Gunpowder, Treason and Plot" is behind us, and the next marker in the calendar is that of Christmas. So winter is upon us, and the heating is back on.
In the summer months, we don't use our heating, but once winter is here, we find the heating is on in the morning and the evening - perhaps even during the daytime! One of the side effects of having your heating on is condensation on your windows.
The problem is the way in which we heat our homes, no longer do we have open fireplaces and lofty ceilings; rather we have radiators dotted around the house, loft insulation and lower ceilings, and we even have nice fitted carpets. All of which mean water vapour cannot escape, so instead, it forms on colder surfaces, and that's on our windows in the form of condensation.
You may find some of your rooms have no condensation in them, while others have water streaming down the inside of your windows. This is due to air circulation and ventilation of rooms. You will find that your "dry" rooms don't have so much water vapour being generated in them, or they have greater ventilation.
While we all have experienced some form of condensation, it's worth remembering that you can get condensation on the outside of your windows too, and just like condensation within your home, this can form on some windows and not others, even if they are right next to one and other. This doesn't mean anything is wrong with your windows or that they have been fitted incorrectly. Condensation on the outside of your windows is a natural thing and can be ignored.
There are three factors that can affect condensation: water vapour content, inside room temperature and outside temperature. We have posted a blog on this not too long ago, and it's well worth reading if you are suffering from condensation.
