The window is waterproofed with a combination of products and the entire shower assembly was flood tested for 72+ hours and inspected by a Vancouver plumbing inspector.
My primary waterproofing membrane for this shower is the blue membrane from Noble Company. I used this Noble Seal TS to tie into the Watts clamping drain . I brought the Noble Seal TS up onto the window and fixed in position with Kerdi FIx. This is outside the recommendations from Noble Company but I have privately tested Kerdi Fix and it's ability to bond to metals in the past - I have yet to run any testing with Noble Sealant 150.
|Waterproofing a window in a shower|
These windows are a tough challange on any job - getting it perfect can be a little troublesome. Your best approach of course would be to contact your suppliers and ask for a detail drawing. Waterproofing windows is not covered in either the TCNA or TTMAC Specification Guidelines.
Common sense is often needed. The window was sanded and cleaned where I bonded to it. The bond was later tested by me - I tried to pull it off later. Once complete the shower pan was flood tested - 3 plus days.
I'm not sure what else I could have done....
In the end you are looking for an approval from the city.
|City of Vancouver Inspection Report|
In Vancouver once a plumbing inspector has signed off on a shower's flood test you are given one of these. Knowing that every shower is inspected in vancouver that has a permit it makes good sense to self inspect these showers being built with no city envolvment.

At the start of the project we set in our curb and a cast iron clamping drain. Below the clamping drain you will notice the red fire-blocking. We skimmed out the face of the framing with Grani Rapid from Mapei.

|Attaching Kerdi to the window with Kerdi fix|
|Kerdi and Kerdi fix was installed prior to the boarders showing up. |
These flaps are sealed to the windows framing and then later set down onto the backer board.
|The Kerdi and Kerdi Fix was installed into the back side of the window trim on the right side.|
Seeing is believing and more so - testing is proof that a concept has merit or will work. I have used Kerdi Fix on many different products and is still my favourite waterproofing material in difficult installs. I do not think I would use anything else to tie into a window.
As we speak I'm playing with a new product from Noble Company that is a lower VOC version of their Noble Sealant 150. I will expierement with this new Sku and see how it compares to Kerdi Fix and regular Noble Sealant 150. I'll let you all know how it goes in do time....
