Description
INSULATION BODY
This invention relates to insulation bodies, particularly although not exclusively to insulation panels of the kind used in building constructions, e.g. for thermally insulating cool rooms or providing acoustic insulation.
Insulation panels used say for insulating the walls of cool rooms or the like and for acoustic insulation are known. Such panels are arranged to be assembled together in a modular form.
Each panel has a back and front face which are spaced apart and are generally parallel to each other. It is also known to provide each such panel with a female edge having a recessed region along part of its length and a male edge opposite to the - , female edge and which has a complementary shape to the recessed region of the female edge so as to closely fit in the female edge of an adjacent similar panel. The present invention relate~ to insulation panels of this kind and such panels will be conveniently referred to hereinafter as insulation panels of the kind defined.
The known insulation panels of the kind defined can have several types of construction. One construction comprises back face and front face sheets which are turned back upon themselves 40 a~ to engage and be secured to the opposite edges of two outwardly facing channel members which define the female edge and the opposite male edge. The manufacturing a~sembly of this kind of panel is time consuming making the panel relatively expensive. This kind of panel is illustrated in Fig. 1 of the drawings.
Another known kind of insulation panel of the kind defined has back and front faces which have edge formation which are ,- 1 ~
., .~
integral with the back and front faces. The edge formation~
terminate in planar webs which extend at right angles to the general planes of the back and front faces so that the web of the back face can be overlapped with the adjacent web of the front face and the two webs secured together e.g. by welding or riveting. The webs at both the male and female edges are overlapped and secured together. Again this kind of insulation panel is relatively time consuming to construct because of the difficulty of working with the overlapped webs and particularly securing of the webs together. Furthermore this kind of overlapped construction provides an area of weakness which can result in fracturing . .
'~, of the connection between the back and front faces when the panel is being handled and particularly when any twisting forces may be applied to the panel during handling. This ., , second known kind of insulation panel is illustrated in Fig.
~ 2 of the accompanying drawings.
-,- It i5 an object of the present invention to provide : .
an insulation panel of the kind defined which is relatively simple and efficient to manufacture and which has improved structural strength.
According to the present invention there is provided an insulation panel having a back face and a front face, the back and front faces being spaced apart and being generally parallel to each other, the panel including a '., .~.. ...

~, , .
female edge having a recessed region along its length, the panel further including a male edge located at the opposite side of the panel to the female edge and which has a male shape which is complementary to the recessed region o$ the female edge so as to closely fit within the female edge of an adjacent similar insulation panel, the front face having two integral webs located at and extending respectively along the female and male edges of the panel, each web extending across substantially the entire distance separating the back and front faces so as to define a cavity within the panel, the cavity having a base wall defined by the front face and two opposed side walls defined by the webs at the female and male edges of the panel so that the cavity can receive and retain an insulating material filling for the panel, the web at the female edge of the panel being shaped so as to define tha recessed region, the web at the male edge of the panel being shaped so as to define the male shape, each web having an edge portion remote from the front face and which turns out of the general plane of the web, the edge portions of the webs being secured to the back face of the panel.
Possible and preferred features of the present invention will now be described with particular r~ference to the accompanying drawings. However it is to be understood that the features illustrated in and described with ' , "'' . .
-~ reference to the drawings are not to be construed as ,, limiting on the scope of the invention. In the drawings:

~ The insulation panel according to the present ;' invention and illustrated in Fig. 3 has a back face 10 and a ,.. :.
' 7'' front face 11 and webs 12, 13 formed integrally with the ,, ,~ front face 11. The webs 12, 13 extend across substantially ,, ;'~ the entire width of the recessed region 16 of the female ~ edge 15.

Although in the preferred embodiment illustrated, the insulation panel is provided with a web 12, 13 at both male and female edges 15, 17 and both webs 12, 13 are formed integral with the same face 11 of the panel, in an alternative possibility one web could be provided integral with a respective one of the faces 10, 11 of the panel, i.e. one web provided on one of the back and front faces 10, 11 at the female edge 15 and the remaining face being provided with a web at the male edge 17. In a further possible embodiment (not illustrated) there may be provided a web at one edge integral with either the back or the front face 10, 11, the formation at the other edge including a separate member (such as in Fig. 1) which extends between and spaces the back and front faces.
The recessed region 16 of the female edge 15 is of generally channel shape and the channel shape extends along the entire length of the female edge 15. The channel shape is defined by a front wall 20, a back wall 21 and a base wall 22, the base wall 22 being defined by web 12. The front wall 20 of the channel shape comprises an edge of the front face 11 which i5 turned inwardly, i.e~ towards the back face 10, and then back upon itself to define a double thickness channel wall 20. That is, the outer thickness of the double thickness channel wall 20 comprises the front face 11 of the panel and the inner thickness of the channel wall 20 is defined by the edge portion being turned ~ack upon the front face 11, the edge portion then being turned to extend towards the back face 10 so as to define the web 12. In this embodiment the back wall 21 of the channel shape is defined by the edge portion being turned outwardly at ~,, ~ 4 '~ ~
,;, ~. ` !
' ' ~
23 to extend parallel to the other channel wall, i.e. the front wall 20.
The male edge 17 is defined by a projecting portion which is elongated so as to extend the length of the panel at the male edge 17, the projecting portion being arranged to fit in the female edge 15 having the channel shape. The male edge 17 is generally similar in formation to the female channel, i.e. being generally channel shaped and having front and back walls 30, 31 and a base wall 32 defining web 13. The front and back walls 30, 31 of the male channel shape are however stepped in towards each other at 34, 35 so as to define a narrower width channel ;
shape 36 which is arranged to fit within the wider female edge channel shape 16. The steps 34, 35 are provided in the back and front faces 10, 11 along and a short distance in from the extreme edge so as to allow the opposite walls 20, 21 of the female channel shape 16 to closely receive the walls 30, 31 of the male channel shape 17 so that the outer surfaces of the back and front faces 10, 11 of interconnected similar insulation panels are substantially coplanar.
The webs 12, 13 are provided on the front face 11 of the panel. The back face 10 has edge portions 26, 27 which are turned in, i.e. towards the front face 11, and then back upon themselves to receive therein the edges 23, 33 of the front face 11 which are themselves finally turned outwardly to form the outer walls 21, 31 of the female and male edge channel shapes 16, 17. The back face 10 is stepped downwardly at 35 before being turned inwardly at 27 and back upon itself.
The edges 23, 26 and 33, 27 of the front and back faces 11, when coupled together in the way described may be fastened '~
1329689 :
together in any convenient manner. For example the edges may be - riveted, clamped, welded or the like. These operations can be .; carried out readily since the connection points will be along an outstanding flange completely accessible from outside of the panel.
The provision of webs 12, 13 extending across the entire ;~s width of channel shapes 16, 17 at the female and male edges 15, 17 provide considerable strength compared to the riveted or , otherwise joined overlapped webs in the prior art. Also this construction enables the panel to be readily assembled, e.g. by sliding the back face 10 along the length of the front face 11 with the edges of the faces being received together as described above. After this the front and back faces 11, 10 can be readily fastened together.
The cavity 40 defined between the front and back faces 10, 11 may include a generally 'U' shaped reinforcing channel 41 which is provided along the length of the panel generally parallel to the female and male edges 15, 17 and spaced midway between those edges. This type of reinforced construction is know in the art. Top and bottom edges of the panel may be defined by channel members 42 received between the front and back faces as is known.
Insulation material of any desired kind may be incorporated in or added to the cavity 40. For ~xample fibreglass, rockwool or foamed insulation may be provided depending on the intended use of the panel as is know in the art. The particular panel construction according to the present invention in fact enables : insulation material to be added to the cavity io before the `t front and back faces 10, 11 are assembled and secured together.
; 6 ,, ~. , ,.
,.
`-For example the front face 11 may be laid flat so that theopposed webs 12, 13 at the male and female edges define side walls of the cavity 40. The top and bottom walls of the cavity may be defined by outwardly facing channel members 42 at the top and bottom edges of the panel as is known in the art so that .:
the panel as a whole has a generally enclosed cavity except for an upper face.- This cav-ity 40 can be filled with insulation material, preferably a compressible insulation material to a height slightly beyond the depth of the cavity. The back face may then be slid onto the front face 11 with the edges being coupled together as desired, the insulation material being compressed slightly between the back and front faces 10, 11 as the faces are assembled together.
The back and front faces 10, 11 may be made of any suitable material such as aluminium sheeting or any other suitable material. The faces or one of the faces may be perforated, particularly in the case of acoustic insulation panels as is know in the art.
The insulation panel according to the preferred embodiment of the pre~ent invention as described above will enable the panel to be rolled so that the panel can be curved along its length, i.e. along the length parallel to the female and male edges 15, 17. The provision of the webs 12, 13 without any fastenings along the webs will provide sufficient strength to the panel to enable this rolling operation to be carried out.
The curved insulation panel therefore may be suitable for constructing roofing, say of sheds or buildings reyuiring insulation. This kind of roofing may be particularly suitable for sheds for intensive breeding and raising of animals.
.
132968~
Further to the preceding description, the panel can have any suitable dimensions depending on the materials and functions of the panel. The thickness of the panel and the length of the channel walls are variable again depending upon materials, uses etc.
The front and back faces and the edge formations of the panel according to the invention may be made by any convenient technique, such as roll forming of sheet metal.
The manufacturing assembly and fastening of the faces of the panel according to the preferred embodiment can be relatively simple particularly in relation to the fastening of the faces together when compared to the prior art. In use when the panels according to the present invention are assembled together, the assembly is completely demountable enabling the panels to be rearranged and reused as desired. The panel is also relatively strong to the extent that the panel can be rolled if desired to have a curved shape, say for use as roofing of insulated structures.
In the preceding description of the preferred embodiment the webs 12, 13 are provided on the front wall 11 of the panel.
However the use of the expressions "front" and "back" are arbitrary and are not intended to be limiting upon the invention.

together in any convenient manner. For example the edges may be - riveted, clamped, welded or the like. These operations can be .; carried out readily since the connection points will be along an outstanding flange completely accessible from outside of the panel.
The provision of webs 12, 13 extending across the entire ;~s width of channel shapes 16, 17 at the female and male edges 15, 17 provide considerable strength compared to the riveted or , otherwise joined overlapped webs in the prior art. Also this construction enables the panel to be readily assembled, e.g. by sliding the back face 10 along the length of the front face 11 with the edges of the faces being received together as described above. After this the front and back faces 11, 10 can be readily fastened together.
The cavity 40 defined between the front and back faces 10, 11 may include a generally 'U' shaped reinforcing channel 41 which is provided along the length of the panel generally parallel to the female and male edges 15, 17 and spaced midway between those edges. This type of reinforced construction is know in the art. Top and bottom edges of the panel may be defined by channel members 42 received between the front and back faces as is known.
Insulation material of any desired kind may be incorporated in or added to the cavity 40. For ~xample fibreglass, rockwool or foamed insulation may be provided depending on the intended use of the panel as is know in the art. The particular panel construction according to the present invention in fact enables : insulation material to be added to the cavity io before the `t front and back faces 10, 11 are assembled and secured together.

`-For example the front face 11 may be laid flat so that theopposed webs 12, 13 at the male and female edges define side walls of the cavity 40. The top and bottom walls of the cavity may be defined by outwardly facing channel members 42 at the top and bottom edges of the panel as is known in the art so that .:
the panel as a whole has a generally enclosed cavity except for an upper face.- This cav-ity 40 can be filled with insulation material, preferably a compressible insulation material to a height slightly beyond the depth of the cavity. The back face may then be slid onto the front face 11 with the edges being coupled together as desired, the insulation material being compressed slightly between the back and front faces 10, 11 as the faces are assembled together.
The back and front faces 10, 11 may be made of any suitable material such as aluminium sheeting or any other suitable material. The faces or one of the faces may be perforated, particularly in the case of acoustic insulation panels as is know in the art.
The insulation panel according to the preferred embodiment of the pre~ent invention as described above will enable the panel to be rolled so that the panel can be curved along its length, i.e. along the length parallel to the female and male edges 15, 17. The provision of the webs 12, 13 without any fastenings along the webs will provide sufficient strength to the panel to enable this rolling operation to be carried out.
The curved insulation panel therefore may be suitable for constructing roofing, say of sheds or buildings reyuiring insulation. This kind of roofing may be particularly suitable for sheds for intensive breeding and raising of animals.

Further to the preceding description, the panel can have any suitable dimensions depending on the materials and functions of the panel. The thickness of the panel and the length of the channel walls are variable again depending upon materials, uses etc.
The front and back faces and the edge formations of the panel according to the invention may be made by any convenient technique, such as roll forming of sheet metal.
The manufacturing assembly and fastening of the faces of the panel according to the preferred embodiment can be relatively simple particularly in relation to the fastening of the faces together when compared to the prior art. In use when the panels according to the present invention are assembled together, the assembly is completely demountable enabling the panels to be rearranged and reused as desired. The panel is also relatively strong to the extent that the panel can be rolled if desired to have a curved shape, say for use as roofing of insulated structures.
In the preceding description of the preferred embodiment the webs 12, 13 are provided on the front wall 11 of the panel.
However the use of the expressions "front" and "back" are arbitrary and are not intended to be limiting upon the invention.
