WALL INSULATION SYSTEM

SYSTEME D'ISOLANT MURAL

English Abstract

Abstract
The present invention provides a system or assembly,
intended to overcome the disadvantages. It provides a wall
assembly, which comprises insulation boards assembled to
form a layer of insulation; a generally flat channel, having
a series or bonds to provide structural strength and also
having a series of regularly spaced teeth or projections
punched along the length of metal channel adapted to be
pressed into the insulation board; and fastening elements
for holding the channel sections in position, securing insul-
ation boards to a wall structure. There is also provided a
generally flat shaped channel member having a central port-
ion, and extending parallel to one another and generally
parallel to the central portion two side flanges which both
lay flat on the surface of the insulation boards to provide
additional structural strength to both the channel member
itself and the wall system overall.

Description

SC~IEDULE "~"
There is disclosed a wal] lnsulatlorl system, and a
channel sectlon for use ln such a system.
At the present time, a common construction technique,
for completing the inside oE a building, includes a layer of
insulation formed from individual insulation boards, and
an inner wall surface formed from dry wall panels. The in-
sulation boards are secured to masonry, by means of channel
sections. rn conventional cons~ructions,the edges of the
insu~ation boards are provided with slots wh;ch are cut into
the board, and run parallel to an ed~e oE the board. With
two insulation boards butted up against one another, this
enables U-shape channel members to engage -the slots at the
edge of the boards. Nails are then driven through -the channel
members, and between the edges oF the boards, and into
the masonry to hold the insulation boards in position.
Dry wall panels c~n then be secured to the channel members,
by dry wall screws, and then completed in known manner. Also,
in known manner, a vapor barrier is usually provided. This
construction has many disadvanta~es. The provision of ~rooves
or slots along the edges of the insulation boards complicates
the production process, and increases the costs of producing
them. Further, i-t considerably weakens the insulation boards.
During transporta-tion, handling and construction, it is
quite easy Eor -the grooved edge portions to be damaged.
The present invention provides a system or assembly,
intended to overcome the disadvan-tages. It provides a wall
assembly, which comprises insula-tion boards assembled to
form a layer of insulation; a generally flat channel, having
a series of bends to provide structural strength and also
having a series of regularly spaced teeth or projections
punched along the length of metal channel adapted to be
pressed into the insulation board; and fas-tening elements
for holding the channel sections in position, securing insul-
a-tion boards to a wall structure. There is also provided a
generally Elat shaped channel member having a central por-t-
ion, and extending parallel to one another and generally
parallel to the central portion two side flanges which both
lay flat on the surface of -the insulation boards to provide
additional structural str.ength to both the channel member
itself and the wall system overall.
It has been realized that insulation boards are oE a
relatively low s-tructural strength. It is for this reason
that it is undesira'Dle to provide unnecessary cuts, slots

etc. in them, as it llnnecessarily weakens them, resulting
in damage during assembly etc. Since the insulation boards
are of this nature, it has been realized that the pro-
vision of teeth or projections along the leng-th of -the
channel members ~rill enable the channel members to engage
and secure the insulation boards in posi-tion.
It has also been realized that systems requiring
factory pre-grooved insulation boards are restrictive in
terms of where channel members must be p~aced. This re-
striction tends to force a situation Or on-site hand
grooving in order to complete the construc-tion.
By simply providing this too-thed channel, these two
problem realizations can be overcome as there is now no
need to provide a pre-grooved insulation board. Once the
toothed channel members are in place, there can still be
portions of the insulation board having -the Eull thickness
of the board extending between the main body of the board
and the portion beneath the channel. In this context, it is
to be appreciated tha-t -the reference to "teeth" covers any
series of projections or the li]ce, which are capable of
penetrating the insulation boards to hold and secure them,
without excessive force being required, and without causing
excessive damage to the insulation boards.
By way of example, an embodimen-t of the invention is
shown in the accompanying drawing, in which:
Figure 1 shows a perspective view of par-t of a channel
member; and
Figure 2 shows a perspective view of part of a wall
formed including the present invention.
In the drawing , a toothed channel member i9 generally
denoted by the reference 1. As shown most clearly in Figure
1, the channel member 1 has a central portion 4 and two side
flanges 6.
The central portion 4 comprises a central strip 8 and
stepped slightly away from the central strip 8, and coplanar
with one another, are two side strips 10. The central s-trip
8 is knurled to recieve dry wall screws. It is also pre-
punched, as indica-ted at 12, Eor nails which serve as
~astening elements. ~Each tooth 14 is generally triangular,
and correspondingly shaped -triangular spaces 16 are formed
where the tee-th 14 are punched in the me-tal. These spaces
16 e~tend across -the two side s-trips 10 in an evenly spaced
patern along the entire length of the channel member 1. It
is to be apprecia-ted tha-t the number, shape and spacing of

the teeth 14 can be varied, dependent upon the materials
used, etc. In particular, it may prove suEEicien-t to
provide suf-~e~}e~ ~rovidc only a few teeth with
large spaces in between, there simply being suEficient
teeth to hold the insulation boards in place.
The toothed channel member 1 can be formed from
a number of different materials by various techniques,
but in this embodiment it is made from 26 gauge galvanized
steel.
ReEerring to Figure 2, there is shown a wall
construction having a masonry layer or wall 20. Secured
to the masonry 20 are insulation boards 22. As shown, the
channel members 1 provide engaging abutting, vertical side
edges of the insulation boards22. The insulation boards 22
are of a semi-rigid or rigid nature so that it is a simple
matter to press the toothed channel member 1 into them.
After the channel members 1 are pressed into position, then
nails 24 are driven -through the holes 12 into the masonry 20,
to secure the insula-tion boards 22 into position. To finish
the wall assembly, dry wall panels 26 are layed over the
insulation hoards 22, the dry wall panels 26 being oE cor-
responding dimensions. Then, in known manner, screws 28
are used to secure the dry wall panels 26 to the knurled
central strip 8 of -t11e channel memoers 1. The knurling
assists in guiding the screws, and preventing them from slip-
ping to one side. The dry wall can be Einished in known
manner. Also, although not described, a vapour barrier
can be provided in known manner.
