Stairs and the Second Stud Frame
Earlier in the summer we had paid a visit to Harrop Proctor Forest Products, a local FSC certified mill. Rami Rothkop showed us his selection of logs, from which he would cut all our timber stair material.
Before we talk about the stairs, I’d like to thank our Mom, Helga Karpinski. Here she is opening a beautiful present of homegrown garlic from Keiko’s mom, Susan. Helga is excited to move into her new home in the spring and without her, none of this would have happened. Thanks Mom!
The material Rami supplied was top notch, and the result is excellent. These are Max’s interior stairs.
You may notice the stair tread hangers in this photo. We used these as part of our strategy to build high quality with standard materials. Using the hangers instead of milling in the treads saved us a huge amount in labour costs.
This may be the most important shot for the passive house enthusiasts. Here you can see a mockup of our triple stud frame. The outer two walls are insulated first. Then the vapour barrier, (VB), is applied to the inside face of the second stud wall.
The third stud wall, called the installation cavity, is built on the inside of the vapour barrier. This cavity holds all of the plumbing and electrical, minimizing the number of penetrations through the VB. It is critical to ensure that the VB is perfectly sealed in order to achieve the all important .6 air changes per hour mandated by the PassiveHouse Institute.
We are confident in our ability to do this, as we achieved .8 ach/hr in our last house, without the use of an installation cavity. It’s all in the craftsmanship!
For those of you wanting more information, I will be posting detail shots of our construction procedure in subsequent posts. Be sure to subscribe in the right sidebar to be notified of new posts.
Whew! So that is where we are now. Hopefully you enjoyed viewing this project as much as we did building it. Now I have to move my very pregnant fiancée from Vancouver to Nelson. We have rented a house in town for the winter, so the camp will be getting shut down as we prepare for snow.
Once we are back, we can get rolling on the second half.
