Why you should use OUR SIPS panels for your next
building project?
Our Structural Insulated Panels do not have bends, bulges,
twists and cups like the increasingly poor quality of most lumber materials.
They are constructed using Structural Polyurethane Foam, 60% to 80% recycled
galvanized steel studs (NuconSteel),
top and bottom panel plates and fiberglass cloth. All connections within the 4'
wide panels are connected using metal rivets. Factory installed electrical
conduit is gray PVC
conduit with 4" electrical junction boxes and protrudes through the top
plate of the wall panel.
We use a metal c-channel as the bottom plate that is
fastened with engineered fasteners to a SIP, concrete or wood floor system. A Bostik
adhesive is placed between the two surfaces to adhere the plate to the floor
system. When a wall panel is placed in the upright position within the wall
bottom plate, adhesive sealant is applied along the bottom and sides of the
panel. Then the panels are connected together at the vertical seams with self
tapping metal screws through a 27" 18 GA steel strap. The vertical steel
studs are then fastened at each intersection with the top and bottom tracks.
A metal c-channel is placed over the top plates to provide
a continuous connection around the perimeter of the structure. Once the SIPs are
installed, construction is of mostly the normal type for the area in which it is
being built.
SIP walls are straight, plumb and square. The
vertical metal studs give you a sound base for the fastening of all exterior and
interior finishes. Drywall is fastened to the interior using commercial drywall
screws. The exterior finish can be stucco directly applied to the panels using a
bonding agent, or any other kind of finish you choose such as Hardi
Board, vinyl siding, T-111 plywood or wood lap siding fastened using self
tapping metal screws. No vapor barrier is required on either side of the wall
panels.
Your SIP Panel building will be one of the most
comfortable, quiet and clean structures you will ever own. Customers have
reported that homes that are built next to major highways are as quiet as a home
out in the country. The difference in the amount of indoor air pollutants such
as dust and pollen are also noticeable due to the air tightness of the panels.
We add fresh air intakes to all of our structures to allow for the proper amount
of filtered air exchange within the structure.
Unlike most types of construction, performance is an afterthought, insulation is
an integral part of a SIP Panel building. Our panel system using Structural
Polyurethane Foam that has an R value of R-23 for a 3.5" wall and R-36 for
a 5.5" wall and this is not counting whatever finishes you use on the wall.
Structural Polyurethane Foam (closed cell) is one of the best insulators
available. This foam will not burn without a direct source of flame and meets
all the regulations for flame spread and smoke. If a flame is applied directly
to the foam it will burn, but once the flame is removed, it will immediately cease to
burn.
Air and moisture penetrations are greatly reduced
because there are so few thermal breaks. This is achieved by precise
manufacturing and installation tolerances of 1/4" around doors and windows
and between panels. The gap that is leftover is filled with a polyurethane
adhesive foam product to assure an airtight seal.
The SIPs panels are injected at the factory with a
Structural Polyurethane Foam into the ends of the panel cavities between the
metal studs, while in a heavy metal mold that is restricting the expansion of
the foam. This causes the foam to be very dense and it adheres to the metal
studs, top and bottom plates. It also forces the foam to impregnate into the
fiberglass cloth that is placed on each side of the panel during the
manufacturing process.
This process of construction creates a composite-like
structural insulated panel that will withstand hurricane force winds of 200 MPH
+/-. When a wood 2" x 4" stud is shot from an air cannon at the
unprotected panels at a speed of 80 MPH, it bounces off just leaving a
dent within the foam, and causes no damage when it hits a stud. The force of the impact is distributed over a wider area
because of the integration of the fiberglass cloth with the foam. The panels can
also be further strengthened with the application of metal lathe, aluminum or
sheet metal skins if desired.
Our SIPs panels can be used in seismic regions because
metal rivets at the intersection/connections allow the metal frame to flex and
return, unlike other systems that are rigid connected. Upon laboratory testing
of the panels for racking, the specimen panels were subjected to a force exerted
from a hydraulic cylinder of over 7,000 pounds on one corner of the panel. This
resulted in a "racking" of the panel of 1 1/2" in the direction
of the force. Once the pressure was released the panel returned to within
1/2" of being plumb. The steel used in the panels have "memory
ridges" formed into the wide surface of the stud that helps it return as
close to the original alignment as possible. There is no need to require
"shearwalls" within our structures unless they are a high-rise or have
unusual circumstantial loadings.
These panels can also be used for roof and floor
systems. With a tested loading value of 190+/- pounds per square foot for a
5.5" foam filled panel. This loading exceeds most building code
requirements.
Let our team show you how our panel system can be used
or adapted to your next building project.
Does green building pay?
It certainly does, according to two recently released
studies documenting the energy effectiveness and impact on rental rates and
property values of green-certified buildings.
One study, commissioned by the U.S. Green Building
Council and conducted by the New Buildings Institute, gathered whole-building
energy data from 121 occupied LEED NC buildings. The median energy-use intensity
for these structures was 24 percent better than the national average for
conventional buildings. LEED-certified office buildings performed 33 percent
better than average. However, the energy performance for LEED-certified
high-energy-use buildings, such as laboratories and data centers, was nearly two
and a half times higher than predicted, indicating a need for improvement in
performance modeling.
The second study, conducted by the CoStar Group,
analyzed occupancy rates and property values of 1300 buildings. It showed that
EnergyStar buldings were selling for $61 per square foot more than noncertified
structures and commanded $2.40-per-square-foot-higher rental rates. Occupancy
rates were 3.6 percent higher. The study also found that LEED-certified
buildings were selling for $171 per square foot higher than noncertified
buildings, commanded $11.33 per square foot more in rent, and had 4.1 percent
higher occupancy.
