How do you stop condensation on bifold doors in winter?
Picking a set of thermally broken aluminium or well fitted uPVC bifold doors should be enough to minimise the condensation in your home for the long term. If you start to notice condensation or misting inside the glass of your doors, this is a sign the seal on the glazing unit has failed and needs replacing. Once the double glazing is replaced, the condensation will clear up.
If the condensation is forming on the surface of your doors, this is actually a good sign because it shows that your doors are an effective barrier for the cold air getting in while trapping warm air inside. Take the time to dry off the glass if necessary, and look at causes of condensation inside your home if it becomes a problem.
