Customer Questions & Answers

In what position is the dryer vent installed in relation to the window - horizontally or vertically?

I need the window to be installed horizontally, i.e., the long edge (32 inch) is the bottom/top and the short edge (20 inch) is the sides. The louvers of the vent should face down towards the bottom edge. I read a review that indicated that the louvers faced towards the side edge. This is not what's pictured on the site. Can you clarify?

Can I get this item in a 30 x 17 measurement

Pittsburgh Corning GuardWise 32 in. x 16 in. x 3 in. Decora Pattern Dryer-Vented Glass Block Window
Asked by: Anonymous
The closest we come to an actual unit dimension of 30" x17" would be the 28.75" x 17.25" and the model number would be D3018DC or we you could use 31" x 17.25" which would be model number D3218DC.

What is the best attachment to hook up to the vent portion? I can't find anything that fits properly.

Asked by: AdamM
You should be able to find the attachment in the appliance department or the duct work department. It will be a small square or rectangle piece of ductwork that bends to a "sleeve" that will attach to the vent.

I would like 2 vents in the unit?

the other vent over 1 space.
Asked by: Ed
You will need to special order your window through the store. The store will need to contact customer service to place your order and determine the vent locations.

38.75 in. x 45.5 in. x 3 in. GuardWise Dryer-Vented Decora Pattern Glass Block Window is rated 4.3 out of 5 by 14.
Rated 5 out of 5 by from Vented Basement Window Install was easy. Had already done 3 other windows so pretty much had it down to a science. Looks fantastic and couldn't be more pleased. Shipped within a week of ordering, which said it would ship after 3 weeks so thrilled it came alot sooner.

Rated 3 out of 5 by from very poor vent the vent is fixed sideways and there is no way for the louvers to close when you are done with the dryer. No spring or way for them to close. The vent stays open with this configuration. Not very well thought out for what is was built for.

Rated 3 out of 5 by from Great Window - Wrong Vent Orientation This product was great, but the dryer vent orientation, which dictates the orientation of the window, was inconsistent with the pictures online. I had seen from other reviews that vents were not always consistently located. As such, I looked specifically for where to specify the orientation of the vent when ordering, but could not find anything. I called Home Depot and asked about the orientation, but was told that it would be consistent with the picture online and that I could return the window if there was any issue. I needed to install the window horizontally, but when it arrived the vent would only close if the window was installed vertically. The vent as pictured was located in the middle of the sort side of the window, while the vent arrived in the middle of the long side. This would prevent it from being installed. It is not trivial to return a glass block window that was delivered on a pallet, and there is no certainty that the next window would be delivered correctly. As such, we cut our window apart with a drywall knife, rebuilt the glass block and vent into the correct layout, and glued it back together with new silicone. The final result was great, but there was a lot of work to correct a mistake that could have been prevented with a simple dialogue box when ordering.

Rated 4 out of 5 by from Nice but the vent isn't as pictured The vent is oriented as if the short side of the window is at the top/bottom. I removed the vent to enlarge the hole in the plastic fixture for a new pipe and made my own flashing so it wasn't an issue. The vent is a bit dinky. The window was packaged well in foam and it's good quality with clear-ish silicon/sealant holding all the blocks together. I found install instructions on the MFG's site. Another reviewer stated type S mortar was good, which I used and worked well.

Rated 4 out of 5 by from The product is well-built and looks great. I needed a glass block window unit with a dryer vent and that's what I got. Simple install, vent works well. Though, the moisture and lint from the dryer vent runs down the window and pools beneath the window unit. It was a personal preference, but I didn't want a water issue over time and have lint sticking onto my window. So I installed a pvc pipe through the dyer vent to stick out a few inches to get the moisture away from my house. Works great, it might have been a little over-kill. But I'm happy.

Rated 5 out of 5 by from Excellent! Its hard to find a window with the thermal qualities of glass block and a dryer vent. Instead of using mortal, I used pressure treated wood and vinyl stop to install. I replace a leaky 1940s single pane aluminum window and I'm very pleased with results.

Rated 5 out of 5 by from Glass Block Window with dryer vent Windows were delivered in about a week vs the 30 days promised. Were sitting on my front porch before I knew they were shipped. Well packaged and in good shape when delivered. Silicone glue used to assemble blocks much sturdier than conventional grout and did not require a band around the assembled window. Close fit of individual blocks make slight irregularities in the assembly obvious up close but not noticeable from a distance. Installation instructions were great except would have helped if they had mentioned that Type S mortar is recommended.

Rated 5 out of 5 by from Good Quality Product was very good, measurements were exact. Well protected with foam for shipment. Will be ordering the same product without dryer vent for other window. Glass block cement used from Home Depot was also of good quality.
