Bubblewrap Foil Insulation Causing Condensation in Loft

Postby Chel1978 » Wed Jan 27, 2016 9:59 am

Hi guys,

In the summer we had the loft floor boarded and foil bubble insulation wrapped across the rafters.

last week I went up in the loft and I noticed there was condensation all over the foil insulation. The work that went into putting to up the foil and boarding the floor wasn't easy, and now that the loft is full of storage boxes etc I'm really dreading that someone is going to say rip off all the bubblewrap.

However I was wondering would fitting a condensation ventilation unit help?

The bubble wrap is from B&q, B&q also have a video on YouTube doing the exact same thing I've done.

I've attached a few images, I really hope you guys can help me and my partner fix this.

Thank you very much

Chelsea :)
