Protecting Timber Windows from Construction Moisture

[benben5555]

We are having timber windows fitted and the manufacturer has warned about damage from excessive moisture from screending and plastering. Has anyone else had this issue, and what did you do?

 

Thanks

Are you windows pre finished. Bare. Or supplied in primer. If you have been warned about moisture intake you need to be concerned. Can you paint them first, and then a light sand, and final coats when installed.

Leave the windows open all of the time.

The windows are fully finished on delivery. Problem with leaving the windows open is that the screed manufacturer says that there shouldn't be any drafts or dehumidifiers used for the first 72 hours to allow it to cure correctly.

 

Similarly with plastering, could leaving the windows open cause the plaster to crack by drying too quickly?

Leaving the windows open won’t bother the plaster or screed

Cemfloor recommend windows stay closed for first 24 hours and then open them all afterwards. There will be a lot of moisture. Most people on here will have fitted timber windows with a screed floor.

That's the factory/supplier watching their backsides, whether factory treated or not, it is a concern for swelling to occur and operational issues occurring. Which they will not take responsibility for, is it a major issue? No, but it can happen hence the warning.

A draught will speed the drying process. Slower drying minimises shrinkage cracking.

Not really 

If it’s going to crack Closed windows won’t make any difference 

and plaster is better with the windows open
