I have recently began removing 50 year old single pain fixed windows throughout my home. I have installed Thermastar windows to this 1960's brick home. Due to the maintainance issues involved I have selected to use PVC moulding on the exterier of the home. All the literature I have read indicates that this product can be installed much like wood and nailed preferrably with stainless steel finishing nails. The problem is this, I installed the windows inline with the rough opening sill, there is a 3/4 inch gap on the exterior of the window followed by the brick surface. I have filled the gap with Great Stuff, trimmed it, and want to affix PVC moulding......I have no expeosed wood to nail it to. I have read some earlier posts and I know that cementing the moulding together is incouraged to prevent srinkage......but how do I attach this to the home? Can I simply use a Type II silicon or some form of construction glue, ie liquid nails??? I could use some advice. I have pictures if this would help however am not sure how to post them here.

 

Don't know whether this is the brand you have, but the adhesive selection should be the same. Note that some things were for interior use only.

As to posting pics, you can upload them to a free site like Photobucket or Flicker and copy the link or IMG info into your post. Make sure whatever you use is an open site (no registration required to view photos) and that you make the pics public.

Take several shots, both overall and close-up and from different angles.

 

Pictures sure would help. Like gunguy said, upload them to a file sharing website, then copy and paste the link here.

You say there is no wood to nail to. I can't for the life of me picture this, unless you are saying that the 3/4 gap that you foamed is where you need to nail. If that's the case, you need to cut all that foam out of there and put some wood in there instead! And if the wood will show, get some PVC trim (1x4, 1x6) and rip it down to size. Once you do that, you should have something substantial to nail your PVC brickmould to.

I'd recommend Vulkem 116 for your sealant- Lowes in my area carries it. But you definately need some fasteners to hold your brickmould on, you can't just glue it on.

As you can tell, "hopefully", by the pictures, the gap between the exterior edge of the window and the interior edge of the brick is 3/4 to and inch in places, this is where I put in the expansive foam. What I may have done wrong here is I installed new windows in the old rough opening which is the same dimension as the exterior brick leaving no exposed wood.....but then again, I'm guessing here. Hopefully you may have an informed outlook.
Thanks for helping

From the photos, it appears as if the windows should have been installed further out toward the brick and then no moulding would have been necessary. Having said that, it looks like you are going to cover up a lot of the window trim with the brick mould!? You will get more responses, but if it were my window, I would try to find some moulding that was 3/4"-1" wide(3/4 quarter round?) and use that and caulk(provided it will cover). Were the windows not available with a wider jamb? Good luck!

 

Mike, as you can see in picture #2 the caulk line from the original window is 2 inches into the brick. The originals were framed in 2 X 8's with quarter round to hold the glass. I extented the window as far out towards the brick as I could and still be able to get a good attachment for the frame. I don't think that quarter round will cover and don't mind covering some of the frame, (frames come in larger sizes....who know, damn). Ultimately, am I way out of line installing this the way it is, at some point I will be selling the house....will this be seen as poor craftmanship?
Thanks again

Hmmm it's still a bit tough to get the perspective on this. Are these fixed windows? Casement?

I'm almost thinking brickmold turned so the thinner part is to the exterior. Attaching it is the issue still though. Countersunk Tapcons into the brick with adhesive and caulk?

Just thinking...maybe Bill, Sleeper, or Mike will have something

 

Yes these are fixed windows, I have added a couple of pictures to give a full view @

And yes, how to attach this to the house. I was hoping I could cut to length, cement in place and bond to the window / house with construction adhesive. I have use concrete screws in the past and have no alway had good luck....probably predrilling with wrong bit????

 

If I had to use the brick mould, I would turn it (maybe with the thinner side to the window) and pre-drill it to the window. Using plastic plug covers to hide the countersunk screws. Hope it works out!!
