Super Insulated Construction
Exclusive Haz-Safe Buildings' Wall Design
aluminum backed 2" thick, R-14.4, Dow Chemical Thermax rigid
polyisocyanurate rigid insulation board is pressed between vertical
wall tubes. 7/8" deep horizontal furring strips are attached
on top, creating an air space whose R-value can be added to 3/4"
thick gypsum and 22 gauge steel sheet, for a total R-value over
from inside building through 2" diameter hole in wall exposes
2" thick polyisocyanurate insulation board. Had the empty 7/8"
air space been filled in with 3/4" thick insulation board,
the total R-value of the wall would be 19.8.
extremes with the cold freezer room on one side and a hot room on
the other are easily handled by staggering the vertical tubes along
the walls, which provides a second thermal break between the inner
and outer wall surfaces. R-values in excess of 30 are available.
Hazmat and Cooler, Refrigerator, Freezer, Hot Box or Industrial Oven
is relatively easy to design a building to meet the necessary technical
disciplines for being blast rated, or to make a building fire rated
or for use as a super insulated enclosure, or room or building. By themselves,
all of these disciplines have to be carefully thought out. But, combine
all these disciplines into one and the same structure, and it becomes
harder. Haz-Safe Buildings easily accomplishes this without compromising
the safety of the workers using the building. Look at this another way.
It is relatively easy to make building as a hazmat or walkin cooler,
refrigerator, freezer, hot box, or industrial oven. But the real trick
is to combine the disciplines. Now, add into this mix a requirement
for any or all of the above to be pre-manufactured and to be in multiple
modules to be shipped in separate shrink-wrapped units and reassembled
outside or inplant at the user's site anywhere in the world. Haz-Safe
Buildings does all that and more, utilizing high quality materials and
the latest components. For example, look below at how Haz-Safe Buildings
bring these design disciplines together in just the construction of
the walls that are blast, fire and, emphasizing below, super insulated.
Insulted Construction with Thermal Breaks
construction designed to increase effectiveness of insulation values
in Haz-Safe Buildings' walls by attaching steel horizontal furring
channels on 24" centers (floor to ceiling) across the vertical
tubular steel members. This is meant to hold applied gypsum panels
away from being directly attached to the vertical tubular members,
creating a thermal break capacity for slowing down the transfer
of heat through the wall. Inserting 2" thick Dow Chemical Thermax
rigid polyisocyanurate foam insulation board (R-14.4) and another
3/4" (R-5.4) into the 23" space between vertical members
and horizontal channels brings total R-values up to 19.8, all within
a 3-3/4" thick wall.
first example above except each vertical tubular member is staggered
along the entire perimeter of the exterior wall so that every other
outer tube is supporting the building's 10 gauge skin. The other
vertical tubes are 2" inside or off the 10 gauge plate and
are supporting 7/8" deep, 20 gauge horizontal channels upon
which the gypsum panels are attached. In addition to the above first
example, a second 2" thick (R-14.4) layer of Thermax insulation
board is pressed into the extra 2" deep air space, bringing
the total R-valve of the wall to 34.2, all within a 5-3/4"
as the second example above except on the outside portion of the
vertical tubes, a horizontal 7/8" deep, 20 gauge furring channel
is attached across the vertical tubes on 24" centers. The purpose
is to attach gypsum panels away from being directly attached to
the vertical tubular members, creating a third thermal break. Inserting
3/4" thick polyisocyanurate insulation in the 23" spaces
between horizontal furring channels brings total R-values up to
39.6, all within 7-3/8" thick wall.
