Installing a gas dryer in a new addition. Dryer is on exterior wall so will use a direct vent.
exterior wall is spray foam insulation and already dry walled and sided.
The question is....after I cut my holes and run the vent I'm sure there will be air infiltration around the existing foam. Would you spray foam around the vent or leave some stand off and seal a plate to the interior dry wall.
i know the IRC does not require a dryer vent to be spaced from insulation.
but, to tight foam it in? Wonder since the vent will only be 10" long if will be hotter due to close proximity to the dryer drum.
