Dryer Vent Through Suspended Ceiling Tile

I have a suspended ceiling in my basement with the thin fiberglass-backed tiles with the white plastic facing. Any issue running a dryer vent through these tiles where the hole is cut exact enough that the pipe touches the tile? I'm not sure how hot a dryer vent gets and I don't want to melt the plastic facing, or worse.

Thanks!

Gas or electric dryer?

May not make a difference but just in case....

Dryer vents typically reach 120 to 160 degrees F. Under fault conditions they can get hotter, as the dryer thermal cutouts are usually 180-190.

Generally, no clearance to combustible materials is required for dryer vents, so it should not be a fire hazard. Whether or not it will soften the ceiling tile or not depends on its material, but I doubt it.

You may find it easier to cut the hole oversize and use a dryer vent collar ring to make a neat job. Use rigid vent pipe (not flex) and make sure the joints face away from the dryer so they don't collect lint and plug up.

It is an electric dryer.

A "dryer vent collar ring" - where can I find one of these? I've searched for 4" stove pipe collars and 4" duct collars with no luck.

Thanks

I've used something like this: http://www.amazon.com/RCI-PVC-4-Trim-Ring/dp/B01593VZ4M

Or you can use a "goof" ring for 4" recessed lighting cans, although they can be hard to find.

Thanks Carbide, that looks like it will work.

How would you attach the trim ring? I cannot screw it to the ceiling tile, as they are the thin, flexible fiber glass type.
