You can buy a bags of cellulose from lowes fluff it up into a garbage bags and dump into attic after you are done on top of the area where you disturbed insulation.

Bathroom fan attic insulation.

Insulate the bathroom exhaust vent fan ducts. Before you rush to the attic or go the roof to check for any leaks make sure the exhaust fan duct is properly insulated and run the fan more frequently for a prolonged period. To avoid mistakes not running it at all consider installing switches with built in timers. Options for venting a bathroom exhaust fan include best to worst.

Make sure vent pipe is insul wrapped. The first step is to head to the attic. Mount fan inside boot. Condensation can be a problem in an uninsulated attic so the homeowners trades resource center recommends installing rigid pipe with a minimum slope of 1 8 inch per foot toward the vent outlet to keep water away from the fan.

Cut hole like an x where elec and vent pass through. Seal boot to existing vapour barrier. While insulating you can make some mistakes. Install a vapour barrier boot where your fan will go.

You may find that the insulation simply needs to be refastened. Seal holes around elec and vent with tuc tape and with accoustic sealant. In un conditioned space such as an attic where otherwise your fan duct will be exposed to cold attic air in winter use insulated solid metal ducting or insulated flex duct. When venting a bathroom exhaust fan make sure to vent the air to the outside rather than into your attic where it can cause mold and mildew to form.

I think you need to go into attic regardless as the fan housing probavly has brackets attached to the attic joists. Through the roof or an exterior gable wall. Or you rent a blower. If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct.
