Insulating attic

I wanted to add more insulation to an existing attic. Currently there is about 3" fiberglass insulation and I think it is about 50 years old.

What should I do? Should I remove the existing insulation or just add on top? Also I like to know what type of insulation, like blow in
or just use the fiberglass

Thanks in advance

Id say the cellulose is the best way to go you blow it in. It seals like better than the fiberglass batt. Most now call for a 12 " to 15 " insulation in the attic. Make sure you dont close off the air vents that are in the overhang of the home. might have to put in the foam spacers so the air can get up in the attic. The big box stores have the insulation and the blowers. Just blower over what you have
