Browse Forums Windows & Doors 1 Dec 14, 2016 10:28 pm Hey Guys, I wonder if you can help. We had a house built for us and we have a big problem with the windows. We have masses of condensation inside the glass and damp all around the window frames. We have black mold growing and flaking plaster. If you ran a fingernail across the plaster, it comes off like butter. From the outside it looks like there is no DPC, and they have used a metal truss above the windows. A foam barrier has been sprayed but that appears to be all. As you can imagine it is cold and we have big draughts. I am English but the house is in Russia – we currently have -20 weather, we are losing heat and we have this damp problem but the house is generally warm inside, part from the draughts. It looks like the foam they used is only rated for -10 according to a few empty cans I found. The plaster is coming off inside and I can feel the foam layer at the top of most windows, so I can only assume this is all we have for a seal against the outside. A question is how can we treat this? I doubt we can get the windows removed and reinstalled. I am thinking of insulating from the outside using batons or shielding with a membrane or foam added? Any help please? http://pasteboard.co/9HeoJunpH.jpg http://pasteboard.co/9HeUIr6sz.jpg http://pasteboard.co/9HfpC02XV.jpg http://pasteboard.co/9HfX8kYwX.jpg Not quite sure how to add photos - can you see from the above? Re: Window Installation Problems no DPC! 2Dec 23, 2016 6:30 pm Hi Jonrus From the limited detail in your pics... 1 Is the window upside down? I ask because I can see what looks like drain holes above the opening sash, but I can't see the full sill. 2 The lintel, the jambs and the sill could be sealed with caulk at the brickwork, taking care to fill the mortar at the brick courses. 3 You can fit a Z flash above the window to keep rain off the top of the window. You can also fit a sill flap unde the sill to push water away from the wall. 4 Sometime, water can get in through the roof, and it shows up at the window. Check the roof.
