In February I had some triple glazing installed as part of a retrofit project. Internorm patio doors and a new front door: KF310 UPVC/ aluminium. first thing on a cold morning I notice the internal front door handle suffers from condensation all over its surface. I highlighted this to my contractor. He returned and looked at the door and told me the installer had forgotten to install an insulation part in the handle mechanism that stops the thermal bridge. He told me he would chase this up and install the missing part. He has just got back to me to tell me the door doesn’t have a handle insulation part; unlike some other manufacturers’ doors which he thought were similar. The door he says is fine. He blames the condensation, not on the design of the door, but on high humidity in the house as I am aiming for an airtight passive house, and have yet to commission my MVHR system. However, I am running a dehumidifier and a hygrometer suggests humidity levels are fine. Has anyone experienced this with their doors? Or have a view on this? I feel a bit let down after paying a high price for doors that I thought would perform a lot better? Thank you for any thoughts.
