Condensation

rrwfotr

hi

we seem to be getting alot of condensation on our windows, hubby is very tight with the heating and some days we dont heat the house, could this be the cause? also when we do heat the house he turns heating off in rooms we dont use, i have noticed this makes it even worse, leaving a small amount of water on the window sill.

Any comments appreciated

thanks

Same here, rrw....tho heating is on when needed, and double glazed windows and doors.
Could be because of extra curtains and insulation.
Would also be interested in suggestions.

I have double glazing and central heating and I am not tight. We get condensation the bay window every morning in winter. I think it is something to do with the air in the room being warmer than the air outside but if someone knows the answer to prevent it let me know.
thanks

Do a search on 'mould' or 'dehumidifiers' on this site - lots of info

I will have a look

Condensation in houses is a complex subject.

You are not going to stop moisture being produced in a property(unless you stop breathing!, cooking etc). It is keeping that moisture at the correct level that presents the problem.

Adequate ventilation is an important factor, but not easy to achieve in many houses.

Dehumidifiers will remove moisture very efficiently but can be irritatingly noisy and obviously use power.

Good afternoon: Excellent advice on condensation remediation is available here... http://www.diydata.com/problem/condensation/condensation.php

Balancing job by the looks of it. Have just made an exterior polystyrene shutter, hoping to alter the outside window pane temperature.
Will know in the morning. From 'Thermal shutters and Shades' by W.A. Shurcliff.

Condensation is simple to cure open your windows........

Before you jump on me, please understand the basics. Air carries water in the form of vapour (that why clouds exist). Warm air hold more water vapour than cold air.

When air cools or comesinto contact witha a cold surface, (it colls down) and is incapable of holding onto the water vapour so dumps it onto a cold surface, (eiether a window cill, glass surface even cold walls.

Washing, kettles and steam generate extra vapour, as does breathing!. The solution is to ventilate the room, extract the air and replace it with less humid air.

Thats where the problem starts, because nobody wants to waste the air they've warmed up especially with colder air they must warm up again.

Look for energy rated windows (A-C ) as they are the best insulators protecting against heat loss, but do understand that this wont remove condensation, as it will still find a coller surface (walls, pipes etc)

the GGF has a good leaflet on condensation

You got the name for it, Sashman. :-)
Looks like time for a de-humidifier, and maybe move the clothes to finish drying into the garage.
This newly made exterior shutter produced no condensation on the inside of the window, but as you say Sashman, it's gotta settle somewhere.

Absolutely spot on!
