Frame enclosure/Structural Insulated Panels
After
we reassemble the barn frame, the next step is
to enclose it. If the frame is to remain a structure
for agricultural purposes, or perhaps a garage
or outbuilding, sheathing the walls and roof with
either old or new boards similar to the original
barn will be sufficient. However, the majority
of our frames are intended for residential or
commercial use and enclosure requires a more finished
appearance to include insulation. Again this enclosure
material with be fastened to the exterior of the
frame, just as barn board originally did, but
will now be viewed as the interior finish directly
against the frame. Most people use a combination
of dry wall on some walls and honey-colored antique
sheathing on other walls. The majority of people
use the antique honey-colored boards on the roof.
We then recommend structural Insulated panels
applied directly to the outside of this first
layer with the finish exterior materials such
as vertical siding, clapboard or wood shingles
applied to the exterior of the panel. After this,
the roof receives either metal, asphalt shingles,
wood shingles or slate. The frame is now fully
exposed to the interior, with the roof and walls
finished in the materials of your choice, which
hide a superior insulation system
Although
the traditional techniques of joining and building
old barns are timeless, the methods used to enclose
old barn frames have changed dramatically over
the years. In the past a conventional light frame
could be built around or in between the timbers.
The frame would then be covered with sheathing
and siding materials on the exterior with drywall
on the interior and the cavity in between filled
with fiberglass insulation. However, this process
was slow and expensive and resulted in an enclosure
which was not particularly energy-efficient. In
light frame construction, the insulation is interrupted
every 16 or 24 inches by a stud or rafter. This
recurring break in a homes' insulation allows
heat to escape and cold to enter at these points.
During the energy
crisis of the mid-seventies, structural Insulated
panels were developed for residential use as a
take off from manufacturers of cold storage rooms.
Because the post and beam framed home market has
grown considerably during the past twenty years,
structural Insulated panels manufacturers sprang
up all over the country to meet this new demand.
Through experimentation and trial and error, some
very sophisticated methods of manufacturing high
performance panels have developed. These structural
Insulated panels consist of rigid foam insulation
sandwiched between layers of sturdy oriented strand
board. The panels are nailed or screwed to the
exterior of the completed frame leaving the frame
exposed to the inside.
Panels can be quickly installed, saving barn frame
owners weeks of construction time and labor costs.
Another advantage is that the panels form solid
walls that deaden outside noise, creating a very
quiet home environment. But energy efficiency
is the most important reason we recommend structural
Insulated panels. Because they wrap the frame
in a continuous blanket of super-insulating foam,
structural Insulated panels lower energy costs
considerably.There is no break in the frame's
"thermal envelope" because the seams
between the panels are sealed with expanding foam,
making structural Insulated panels ideal for soaring
ceilings and large open spaces common to old barn
frames. Today, the majority of our old barn frames
are enclosed with structural Insulated panels
which showcase the beauty of the frame and allow
the timbers to be exposed inside the home.
