During my research of acoustic panels, i read a number of times that placing acoustic panels made up of owenings corner can actually keep a room warmer? Just wondering if anyone can provide an input, i dont care either way but it would be nice plus since my HT is cold in the winter, it does make sense since the fiberglass material is insulation used in houses

They insulate but will have no affect as such unless they are placed somewhere that actually cools your room.

I wouldn't look upon these kinds of treatments to provide any additional warmth ... obviously they have some minor insulating value.

Now...to mince words and split hairs... :)
Technically, an absorber of kinetic energy (sound energy) is converting kinetic energy to heat. Now while this conversion can be both calculated and measured it's not going to be perceptable to we insenitive humans.

Yep, Dennis is spot on. Don't plan to insulate the room from the inside using acoustic panels...definitely won't work.

Your equipment and Projector (if you have one) will provide plenty of additional heat for your room.
