developing our product line with the industry leading Godfrey
Lumber Company, we had one simple goal in mind
to build the strongest and best looking engineered (or manufactured)
log and timber frame homes in the industry. Through a myriad of
technical research and expert artistic guidance here's how we did

uncovered the past problems of log and heavy timber frame homes
& eliminated them.
perfected a lamination system that replicates the natural beauty
of solid wood logs & timbers.
pre-engineered & pre-manufactured materials so that do-it-yourselfers,
as well as professional installers, could erect our homes error

the difference between log and timberframe structures?
homes are constructed from horizontally stacked logs that have
not been milled into conventional lumber. Built for centuries
in Scandinavia, Russia and Eastern Europe, Swedish settlers brought
the craft to North America in the early 1700s. In the 1920s, the
first milled log housing appeared, using precut rather than hand-hewn
logs. While most log home manufacturers today still market similar
products, Sloan's Mill envisioned and developed an engineered
log building system that solves the structural and appearance
problems of the past.
framing is a type of post and beam construction in which a frame
is created from solid wood structural timbers connected by wooden
joints. Also a centuries-old craft, timber framing at Sloan's
Mill has evolved into an advanced technology that produces visually
appealing timbers for posts, beams and other supporting elements
to eliminate previous timber problems. Compatible with building
systems such as logs, stud systems or structural insulated panels
(SIPs), timber frames may be covered with enclosure systems that
include exteriors of wood, stone, brick, stucco, etc. Interiors
often feature exposed structural timbers that frame walls of drywall
or wood. Timberframing lends itself to both residential and commercial
construction in a wide variety of architectural styles and allows
for almost unlimited interior configurations.
do engineered logs prevent shrinking, settling, cracking, warping
in the industry agrees that the most common and expensive problems
with log homes are the shrinking, settling, cracking, warping
or twisting that occurs as solid heavy timbers dry out. Most logs
that are kiln dried initially average around 20% moisture content
following the kiln process and then slowly dry out through the
years to about 12%.
As the solid timbers release moisture,
they often shrink or change shape creating large cracks or gaps.
While cracks or gaps can and must be caulked to prevent cold air,
insects and moisture from entering, it is an expensive and time
consuming project which will likely require repetition several
times before timbers completely dry. If not corrected, more costly
damage can occur due to rot. Parts of the home may settle more
than others over time, creating structural problems.
manufacturers have tried to minimize shrinkage in a thousand different
ways, our extensive research indicates that there is only one
surefire way to prevent the problems that arise from shrinking
logs to dry the wood below 12% moisture content before
Without providing a lengthy explanation
regarding the technical difficulties of kiln drying wood evenly
and uniformly throughout a log, trust us when we say that the
only true solution to reducing moisture content on the interior
of a solid log is to slice it, dry each piece to the desired moisture
content individually and reassemble the slices with an industrial
strength glue stronger than the wood itself.
The result is an "engineered,"
"manufactured," "glue laminated" or "glulam"
log that will not shrink, allow large cracking, warp or twist.
While checks (small nonstructural cracks) may still occur, as
they do in any kiln drying process, they are barely visible and
cause no structural problems. Even stronger and more stable than
the original, the new log looks no different from the inside or
outside. The only way to distinguish an engineered log is by examining
the ends. However, as the log naturally weathers, even the ends
are hard to distinguish from a solid log.

did Sloan's Mill eliminate weak butt joints?
weakest links of a log home have historically been the joints
where log ends butt together. If not properly joined, gaps can
create air and water leaks. Most manufacturers use a wood spline
that requires caulking and sealer to prevent leaks. But, while
standard joints usually suffice to prevent leaks, they do not
provide any structural integrity to the joinery.
Dovetail Butt Joints
to our expert engineering process, Sloan's Mill engineered dovetail
butt joints not only seal the joint but provide unsurpassed structural
did Sloan's Mill solve issues regarding square and plumb timber
expert installers know the detailed "ins" and "outs"
of obtaining square and plumb corners, inexperienced installers
or DIY homeowners can greatly weaken the structural integrity
of a log home with imperfect corners. Additionally, imperfect
corners can also cause air and water infiltration.
Sloan's Mill engineered heavy timber corner system solves the
problem for all installers. Through mortise and tenon joinery,
our corners are attached to heavy timber corner posts. The result
is an easy-to-install, straight corner that produces a solid air
tight corner and provides structural integrity to the home.
long will engineered wood timbers last?
the questions we are asked most often concern the strength and
life expectancy of engineered wood timbers.
to Last with Strength and Versatility
us begin by saying that the wood fiber in an engineered log would
disintegrate from age before adhesives would break down. And,
pound for pound, laminated timber is stronger than steel, allowing
beams to span long distances with minimal need for intermediate
As for its history, laminated wood
is not a new idea. Archeologists have found traces of laminated
wood in the tombs of Egyptian pharaohs. Closer to this century,
building construction utilizing glued laminated wood began in
Europe during the late 1800s. One of the first recorded uses was
in Berlin's 1890 Reichstag Building. Today, the main terminal
building at Norway's Oslo Gardermoen Airport is the largest laminated
wood structure in the world.
The logs engineered for Sloan's
Mill homes are built to structural laminated specifications by Godfrey
Lumber Company. Free of environmentally harmful formaldehyde
binders, the specialized glue used by Godfrey's creates an irreversible,
waterproof bond between layers that actually gets stronger with
age. If you were to hammer and chisel along a seam to attempt
to separate the layers in one of our logs, you would find it impossible
to do so without tearing the wood itself.
