Condensation in lofts occurs when humid air makes its way through insulation or other gaps into the loft space and hits a cooler surface leading to beads of moisture on timbers, lintels and on the underside of the roof.
How do I stop condensation in my loft?
Avoid blocking air vents, open up window trickle vents, don't cook/bath/shower without thinking about ventilation. Don't dry clothes on radiators during cold weather spells, if possible use a tumble dryer and if not, keep a window at least partially open to vent the moisture.
How do I stop condensation in my attic?
Preventing attic condensation
- Make sure kitchen and bathroom exhaust fans aren't routed into the attic. They'll only bring more humidity to the space.
- Regulate the attic's temperature. Use ventilation to keep the temperature consistent and avoid heat buildup that melts snow on the roof.
- Insulate and air seal.
