Attaching drywall to cement block through 2 inch foam insulation

Posted by Robert.Thompson on April 1, 2009, 11:32 am

Hello:

I have a cement block basement that is insulated with 2" foam glued in
place.

To meet the building code, I must cover the foam with drywall.

What methods, other than furring and expensive 'Tapcon' screws, may be
used to attach the drywall?

Thanks for any suggestions.

Rob.

Vapour barrier first or is the insulation or dry wall foil covered?

The foam is taped and is the type that may be used below grade (there
is 2" of it under the cement floor as well) and is its own vapour
barrier.

Shoot down or tapcon some 2-1/2" metal track (at least 1/2" off the
foam) and stud it out with metal and then drywall.
