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 will be
fastened to the exterior of the frame, just as barn board originally
was, 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 our 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 three decades, SIPS 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(SIPS) 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. And now with a new awareness about “global
warming” and energy conservation, SIPS have become commonplace in the
newly built environment.
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.
