The next stage of the process involves closing in the building from the elements. Typically, the entire wall and roof structure is enclosed with stress skin panels. This system creates the tightest, most comfortable homes on the market. Drying-in
also includes the installation of windows and doors.

Stress Skin Panels

For most of our homes 6" EPS Foam panels provide the best option for insulation and versatility. Because panels are attached to the outside of your frame, they allow for the entire depth of your beautiful, hand crafted timber frames to be exposed. Although very efficient a air exchange system must be installed in order to get fresh air in the home. For more information check out the website of our supplier Foard Panel.


Wet-sprayed cellulose increases the R-value (insulating capacity) of 2x6 walls to R-23 vs. R-21, when fiberglass batts are used. The insulation is sprayed in wet so it fills in and around pipes, wiring and other obstacles to traditional blanket insulation. It then hardens to stay in place. The fiber content is made from recycled newspaper, which reduces environmental impact. The binders used are stable so there is no off-gassing. The result is an environmentally-friendly insulation that keeps the home warmer in winter and cooler in summer.


There are many other insulation options that incorporate natural materials that both insulate and breathe well. This shop owned by Makaio Maher has walls constructed of straw bale. It has a high R-Value and once plastered has the ability to wick any moisture to the outside.

“I thoroughly enjoyed working with Luke, Keone, Caleb and the entire crew from our first discussions to the last piece of slate we hung on the roof. The house and barn are absolutely beautiful.  Everything came out as good or better than I had imagined and the end product, with all of its natural and artistic touches, is truly one-of-a-kind.  There are many things I learned that I hope to carry into my next project and I look forward to having the Old School crew involved in that too!  You should all be very proud of your work.”
