Plastic glass may bubble and discolor or even melt down if the temperature gets out of control. Single strength glass can be cut to fit by HD and will not cost you a bunch of money. Double strength glass is better only because it's easer to handle. Pick up some silver furnace heat tape to seal the edges of the hood to keep the air moving through the hood and not vent into the room. A Dayton blower works but they are a little noisy you can have HD order inline vent fans as long as the vent pipe run is not to long the inline fans can work.

It's better to push the air through a hood then it is to pull it through....fyi
Zandor Reviewed by Zandor on . Zandor, Karmaxul, exhaust fan advice? Ok, spring is definitely here and it's time to vent my light outside. I've got a sunleaves reflector and I need to mount a fan that I can easily duct outside and easily mount to the hood. What can you recommend that the Home Depot carries? I'm hoping for something that won't take too much messing around to get it working. Also, Is it worth while to put either some plex or glass over the light to help with heat transfer? Would plexi glass work, or would it melt under a 400 watter? Rating: 5
