We carry out misted glass unit replacement in Chepstow and across the NP16 area. If a roof lantern pane looks cloudy or wet between the two layers of glass, the sealed unit has failed and moisture has got inside.
Is it time for misted glass unit replacement?
- One pane looks hazier than the others
- Misting that comes and goes with the weather
- Water marks or tide lines inside the unit
Why it happens
Water sitting on the edge
If the unit's edge sits in water because the eaves don't drain, the seal fails sooner.
Movement and age
Thermal movement and age wear the seal; units at the bottom of the lantern often go first.
Roof lanterns in Chepstow
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
