Customer Reviews

12 in. Automatic Damper for Turbine Vent is rated 4.5 out of 5 by 32.
Rated 5 out of 5 by from Easy Installation, & Works In The 'Frig... LOL I got 2 Turbine Boss', put them in the frig, they closed & I let them warm up, they opened as advertized. I have 16" turbines so I plugged the gap with insulation. I've checked them in the morning & they're closed, checked them later & they opened all the way. So that saves me from bagging & un-bagging the turbines, good to go.

Rated 5 out of 5 by from Amazing idea! This is an amazing idea! Put the little coil in it's pocket CORRECTLY and it opens in heat and closes in cold. Just put it inside the turbine frame, put the turbine on the frame and you're done. No more covering your turbines in the winter and taking them off in summer. Manufacturer VERY responsive. Within minutes of emailing a question I received a phone call with the answer. AMAZING customer support! Unlike many companies today. Don't hesitate to try this product.

Rated 5 out of 5 by from It DOES ventilate in winter. Respnding to: PJinSoCal.... Please see the 'Energy Guide". Notice that Turbine Boss DOES vent attic moisture during winter. You choose the 'Winter Ventilation Rate' when installing. It's easy. Also don't try to stop the turbine from spinning...rain will come into the attic. This is a great way to save energy.

Rated 4 out of 5 by from Worth a try I had a roofer help me install two of these Turbine Boss vents along with two new 12' Whirlybird Turbines. Initially the roofer was sceptical that they would perform as indicated on the box, but after we assembled and inserted them into the turbines, he asked me where I got them. When I told him he said he was going to start recommending them to his other customers. Based on his endorsemnet, I feel good about trying them out on my own roof. I'll need to wait until it gets cooler to confirm the vents fully close but the box says you can test them in your freezer if you doubt their claims. Pros: Fair price Easy assembly Cons: Only available online at Constructed of plastic. I thought they'd be sheetmetal.

Rated 5 out of 5 by from Damper These things really work! Put it in a separate garage, open in warm, closed when cold. Keeps garage about 5-8 degrees warmer in cold weather, silent operation.

Rated 5 out of 5 by from Turbine Boss Appears to Work as Described. Anyone who can get on a roof can install this product. Instructions were simple and was simple to install. Tried it out in the refrigerator prior to installation to make sure it really worked and it did! The product is only plastic so hopefully it lasts a long time through the Texas summers up on the roof. So far this winter, my house has stayed at least 3-5 degrees warmer than previous winters. Not sure it is from the Turbine Boss or my new windows. I believe a little of both. So I believe having this installed is better than having the turbines wide open or not having a ventilated attic by bagging the turbines. So for the price, I believe it is worth purchasing. Plus it appears the product is made in Dallas and I believe in supporting local companies.

Rated 5 out of 5 by from Works as advertised. My attic during the recent Dallas Ice Storm was tolerably warm not freezing like it used to be in 18 degree weather. I looked at them they were both closed. The assembly was a little silly. There were things that could have been done before packaging. Fairly easy to install for the most basic of DIY'ers. It is a one time install for those who climb on their roof to put trash bags on their vents.

Rated 5 out of 5 by from IT WORKS!!! IT WORKS!!! I pretested before installing and it seems to do the trick. Simple and easy to set & install. Won't know about the benefits until we get into some cold weather, but it's got help in retaining most of the attic heat in the winter months.
