The manufacturing of Sing Square Logs starts with quality Douglas fir, western red cedar, or pine taken either from small logs or pre-milled lumber. The lumber is then dried in Sing Home’s kilns until the moisture content is stabilized at around 12%.
Our patented sawing technique is used to produce quarter-sawn, all vertical or straight grain wood strips from the lumber, with their internal stress relieved. The strips are then laminated with non-toxic glue to form one side of the Sing Square Log. Two laminated “‘walls”, with their wanes and imperfections turned inside, are then joined together with wood spacers and metal fasteners to form a single log assembly.
The quarter-sawn, vertical grain laminates give the Sing Square Log its remarkable dimensional stability— with virtually no shrinking, checking or splitting.
About Our Logs
Most lumber available is plain sawn (also called flat sawn), which produces the maximum yield and therefore the greatest economy. Plain-sawn lumber has varying grain orientations— the annual growth rings can run parallel, diagonal or perpendicular to the face of the board. This variation causes un-even drying and the board has a greater tendency to warp (cup, twist, and bow). The board will also shrink considerably in thickness as well as width.
Quarter sawing produces lumber with annual growth rings running almost perpendicular to the face of the board. Boards with consistent vertical grain orientation tend to remain flat despite changes in moisture content. This dimensional stability gives quarter-sawn lumber its most desirable quality. Quarter-sawn lumber also has superior ability to hold paints and stains. Vertical grain lumber commands a high premium because quarter sawing requires more time and skill but yields less board footage.
The Sing Square Log’s thick double wall provides the thermal mass to absorb, store and slowly release heat over time. This means that it takes a long time for temperature outside a Sing Log Home to change the temperature inside.
Building with Sing Square Logs
Building with Sing Square Log is simple and straightforward. The first layer of logs is anchored to the foundation with the supplied 1/2″ thick steel plates.
Subsequent layers are stacked up by applying construction adhesive to the double T&G logs, then fastening them with the supplied Olylog© screws.
Two laminated ‘walls’, with their wanes and imperfections turned inside, are then joined together with wood spacers and metal fasteners to form a single log assembly.
