Most people have never seen windows like these. European style, tipple pain, argon gas filled, no thermal bridging, R-8 for the opening windows. German Passive House certified. KlearWall windows, the North American branch of Munster Joinery and are made in Ireland. Here is a thermal image of the windows performance. Out side air temp 15 and inside temp 65.
How they work: First the handle, when down the window is locked. Then, when at 90 degrees the top tilts in for ventilation. Lets air in but keeps the rain out. Also secure enough to leave open while your gone.
In the up position the window swings in. Wide open. The Europeans say they only do this for cleaning. A friend in a passive house says the same thing. He says the tilt opening is more than enough ventilation.
Note the latching mechanism. The windows latch in 4 different location to ensure an air tight seal.

How do you like the Windows and did you also go with Klearwall for the doors? We are seriously looking at the same brand and would appreciate your thoughts.

Now after living with the doors for a year and seeing how they build houses in Ireland I’d talk to my builder about beefing up the door framing. The door are better than anything you can find for a normal American house. but a stouter frame the normal would be nice. They are very well built and heavy.

How have the Klearwall windows held up? We are also considering installing them in our house.

Sorry for the delay, we were in Ireland for a two week vacation and are now catching up. The Klearwall windows are great. No problems with them. I figured out an easy way to add screens. It only cost about $35 a window. I did them myself. On our Ireland trip I didn’t se a single screen.

Hi there. We just bought Klearwall windows for a new house and are now wondering about the screens. I know they don’t use them in Europe but we do need them where we live (in the Northeast US). How did you make the screens? Our windows are aluminum. Any advice appreciated. How are the windows and screens holding up? Thanks.

My windows were set at the center point of the wall, 5″ back from the out side. I had a couple local window/screen guys give me estimates to install screens. It was about $250 per window. My window framing had a 1/4″ lip about 1″ in. I bought 1/2″ channel at Lowes, painted it to match my trim and installed it on the bottom, the had my windows made with springs on one side. I measured the screens for a tight enough fit with the springs down in the channel. They fit a tight enough to hold and keep bugs out and they only cost $35 per window. My email is ed.jenks@yahoo.com send me an email and I’ll send you some photos.

We did brake a latch on one window. My wife either tried to swing a window in vent position or the reverse and broke the swing/vent arm. Chris from KlearWalls came down and fixed the window and checked the adjustment on all our windows and doors. A great guy.
