Link to first post on ideas

When I started to look into converting small free standing garage into my now shop I new right off I would need to get the dist collector and air compressor out of the room. Not really having a background in shop building. Fast forward I get the shop done, install the heat and dust collector. I later insulate the building and everything looking good.

Well I forgot to think about all the heat and now AC that’s getting sucked out of the shop. So off to the internet I go. Looking at different ideas I decided I’d built a return in wall on the inside of the shop that will lead into a box with baffles and some sound insulation. I will also be adding some insulation in the lean-to now that I’ll be heating and ACing it.

So far I’ve cut the whole in the wall for a 10X10 vent and built and cut out the parts for the box that will be 20X25.

More TK this weekend.

OK well I had the chance to finish up the sound baffle and return for the shop. At the same time I installed the return I also insulated the lean as things are starting to fill up an figured I might as well get things done. Plus working with insulation when it’s 90 out is way lots of fun.

I had ordered some Acoustic egg crate Foam from The foam Factory. The price was quite good and shipping only took about a week. I bought some for inside the box and also glued some to the inside of the metal double door.

After everything was done I was quite happy with the lack sound travel but haven’t used a DB meter.

Sorry about the delay in replying. I had thought the site would have let me know someone posted.

I bought the foam here:

The foam Factory had the best price. I also added some of the egg crate foam to the back of the doors into the lean to where the cyclone and air compressor are located. It really helped reduce the sound bouncing around.
