This week has seen the installment of one of the most researched aspects of the house, the windows! The windows we chose to go with were through Klearwall (www.klearwall.com). The windows are the Future-Proof line and the exterior doors are from the Eco-Clad line. We found that these windows and doors which are manufactured in Ireland gave us the best thermal properties for the best value. It was hard though to order such a large component of the house having never seen the product in person. We had to trust that the videos and images that we saw were true to the product and also the fact that they are Passive House certified.
I must say that we haven’t been disappointed by the quality of the product. When the windows first arrived we were amazed by how heavy they were! They are SOLID!! With triple glazing and 5 inch insulated frames they are build to preform. The windows open with the “tilt and turn” mechanism and the doors have full panes of glass in them.
The installation of the windows and doors is key to ensure that there is no thermal bridging and that there are no places that would allow for air leakage. It is quite time consuming compared to installing traditional windows and requires huge attention to detail.
The locking mechanism on the windows is impressive. It’s hard to explain other than to actually close a window and turn the handle into the locked position. What is really neat is that you can actually see and feel the window sealing as you turn the handle. No air leakage!!!
So, without further adieu here are some pictures of the progress this week!
