Browse Forums Windows & Doors 1 Sep 29, 2019 11:48 am Hi all, Here is something else I noticed recently that is a bit strange with our windows. We've noticed water both pooling on the bottom section of the window frame (external) and also as you open the awning sash water dripping from the corners. Anyhow after looking more closely at these window's specifications, I think I may have found the issue. But I want to see first see if anyone else can spot it.....and if the setup in terms of seals etc on our windows is a problem or not? I think these windows actually have a few issues, and from the next few images I can see possibly 2-3 problems? Keen to get some feedback if anyone has ideas or general comments? So here is a vertical profile of the window specs. Drainage slots are shaded blue and I have also highlighted the frame rubber seal, that the awning sash closes onto.Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This is an external photo of the bottom right corner of one of the awning sash's.Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This image is one of our windows. This is taken inside, and you can see the gaps that we typically have on the outside rubber seal b/w the frame and glass.Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This is pic of the rubber seal on the window frame that the sash clamps down on when you wind it in closed.Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This next image is NOT one of our windows. It is the same type but from the showroom of a different fabricator (same window system manufacturer though). This is looking external, from beneath the awning sash with it slightly opened. The arrows indicate the seals and also below that you can see a drainage slot.Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This image is of the same 'sample' window from a different fabricator. This is looking from inside, as the lower left corner of the awning sash with it opened slightly. Red arrows point to a rubber seal.

I can see drainage where I would expect it, the water is dirty presumably from building.

This I think is blocking the drainage slots. So because there are gap in the glazing bead, the water enters the sash glazing pocket and then drains out of that first section but will be getting blocked at the final drain exit slots due to the rubber seal. Well that's my theory anyhow. This is a separate issue to the one where I am showing my 'flimsy' rubber seals on the main window frame (that the sash clamps down onto when it closes). I notice onsite today they appear to have replaced all those particular seals to something thicker. But I won't know for sure until we next meet with our supervisor at site. --------------------------------------------------------------------- Check our Homeone build blog here Re: Awning window & seals - any obvious issues?... 4Nov 01, 2019 1:27 pm Hi Darb74, As I have spent many years fabricating windows it does appear that there is a bottom seal installed where it usually is removed (or not installed). I would be checking the head piece has a seal installed otherwise the window maybe installed upside down (or sash is upside down). Otherwise just pull out that bottom seal. The photo depicting the small gaps in the rubbers where the double glazed unit is would not cause an issue as there are weep holes in bottom sash which will allow the water to escape. Bear in mind if there is a seal on the bottom sash covering the weep hole that could cause insufficient water egress. I have drawn a couple arrows on the drawing so you understand what I mean.

I decided to remove the section of bottom rubber seal that was blocking the drainage slots on the lower external frame. Our building supervisor initially agreed with us that it didn't make sense to have that lower seal installed over the drain holes, but he didn't do anything about it (or ask the window fabricator to sort it out either).....so like many things on this build project we have just fixed it ourselves. My next job is to try and better seal the external glazing bead rubber to stop the water getting into the sash in the first place. --------------------------------------------------------------------- Check our Homeone build blog here Awning window & seals - any obvious issues?... 6Nov 07, 2019 6:40 pm darb74 Thanks lached for that info, and I think you have confirmed what I was thinking.

When I fabricate awning sashes I silicon in each corner between the glass and glazing tape. This will ensure if the glazing rubber does retract (usually due to the weather) that the water will not penetrate into the actual sash itself. Good luck!

So do you run a silicon bead all the way along the bottom of this section? We have already had some silicon put into a few bottom corners, but I think based on how much water is still appearing under the frame I might need to run some the whole length of the lower frame?...like you suggest where the glazing rubber is located but obviously has retracted. --------------------------------------------------------------------- Check our Homeone build blog here Re: Awning window & seals - any obvious issues?... 8Nov 07, 2019 7:08 pm darb74 lached darb74 Thanks lached for that info, and I think you have confirmed what I was thinking.

No just in the corners. The system we use is slightly different to what you have. Where is the water pooling? It is completely normal to have water in the step down area (i.e where the weep holes are). I’m restoring all my 40yr old windows and I want to install seals around the casements. I’ve sanded back and oiled the frames with sikkens. My plan is to box up inside… 0 6518 4 14301 I am looking at building a house. Has anyone used Construkt Homes (based in Adelaide)?
