Is there a law requiring insulation in attics?
DO NOT PUT ANY THING METAL IN THE MICROWAVE! You can not but anything metal in the microwave including aluminium foil! It will spark and could destroy your microwave and start a fire.
No foil in the microwaveNot even a tiny bit that might have stuck to your food and you didn't knowTrust meI know from experience.
Its' very wise that you thought of asking that on hereNext time you have some questions as to whether or not to do something, follow your gutNow does anyone know if it's okay to put my tongue on a freezer wall? I had a fever and was wondering if this would work faster than medicine.
Wow, you really got many bad answersWrite Reynold's Aluminum for its microwave cookbookYou should never completely surround an item in metalSometimes a pie or cake will cook on the outer edges, but not in the middleIn this case you can put it back in the microwave with foil covering the outside of the cake and leaving a hole in the centerThe mass of the metal you put in the microwave should be less than the mass of the food left uncoveredSome microwaves come with metal racks so you can cook on two levels.
As the other answers state, check your local building codeRemember, well installed attic insulation cuts energy costWith energy costs getting ready to take a big jump soon, it would be a good investment.
