The invention also provides an insulated panel assembly including a plurality of the panels of the invention.

Brief Description of the Drawings The invention will be more clearly understood from the following description thereof. given by way of example only, with reference to the accompanying drawings, in which :- Fig. 1 is a cross sectional view of a panel according to the invention : Fig. 2 is a side cross sectional view of portion of two adjacent panels according to the invention separated; Fig. 3 is a side cross sectional view of the panels jointed together ;

<Desc/Clms Page number 4>

Fig. 4 is a cross-sectional view similar to Fig. 3 with seats in place ; and Fig. 5 is a side cross-sectional view of alternative panels jointed together.

Detailed Description of the Drawings Referring to the drawings and initially to Figs 1 to 4, there is illustrated an insulated panel 1 according to the invention and comprising an external sheet 2, an internal sheet 3 and an insulating core 4 between the external sheet 2 and internal sheet 3. The sheets 2 and 3 are typically of steel material and the core 4 is of polyurethane or polyisocyanurate foam material which fills the space between the sheets 2,3. The panel 1 is in this case typically used for cold-stores.

The external sheet 2 and internal sheet 3 have profiled joint-forming portions for connecting adjacent panels, on assembly as illustrated.

The external sheet 2 has an external male projecting part 10 and an internal male projecting part 11 on one side for engagement, on assembly, with a corresponding extemal recess or female part 12 and internal recess or female part 13 respectively on the opposite side of the panel. A seal 52,53 may be placed in one or both of the recesses 12,13 for sealing engagement, on assembly, with the male projecting parts 10,11 of an adjacent panel. The seals are typically of silicone and are site-applied.

Both the external sheet 2 and the internal sheet 3 are turned back to define a male projecting part 10,11 on one side and a female recess part 12, 13 on an opposite side of a panel. Each male part 10,11 comprises an outwardly extending leg 20 and an inwardly extending leg 21 which terminates in a clip portion 22 which is embedded in the insulating core 4. The corresponding recesses 12,13 are formed by similarly shaping the ends of the external and internal sheets 2, 3. The recesses 12,13 are

<Desc/Clms Page number 5>

defined by an outwardly extending leg 24 and an inwardly extending leg. Again, the sheets 2,3 terminate in clip portions 23 which are embedded in the insulating core 4. <img class="EMIRef" id="024174279-00050001" />

The outwardly extending leg 20 extends at an angle 6 of from 150 to 250, ideally about 19"to the horizontal. The inwardly extending leg 21 extends at an angle ss of from 2 to 80, ideally about 50 to the horizontal. This facilitates ease of engagement of a male projecting part in a corresponding recess whilst ensuring adequate insulation at the joint and facilitating filling of the area defined by the male projecting part with foam on manufacture of a panel.

The insulating core at the edges of the panel between the joint forming portions engage on assembly as illustrated in Fig. 3 to provide an insulated substantially airtight joint. In this case the exposed section of the insulating core is of generally trapezoidal shape with a male part 30 defined at one edge and a female recess part 31 defined at an opposite edge. The webs of the trapezoidal sections of the insulating core extend at an angle of from 100 to 120 , ideally about 1100 to the base or top of the trapezoidal section. Thus, the angle a is about 200. This facilitates effective jointing whilst facilitating economic manufacture of the panel.

On assembly, the exposed gap g is about 3 mm to facilitate expansion and contraction, in use.

A seal trap is also provided at the joint between the panels at least on one of the inside and outside, in this case on both the inside and outside. The seal trap is defined by a recess 40 provided in the outwardly extending leg 20 of the male projections 10,11 and an angled lead-in portion 41 of the sheets 2,3. After on-site assembly of the panels, a waterproof sealant 50 such as a gun applied silicone may be injected into the region defined by the recess 40 and lead-in portion 41 through the outer and/or inner gap- The sealant 50 becomes trapped between 40 and 41 and is firmly retained in situ. on setting. This is important in ensuring that the integrity of the seal 50 is maintained

<Desc/Clms Page number 6>

when the exposed walls of the panels are washed for cleaning, in use, even when cleaning is carried out using pressure jet washing.

In use, the panels may be overlapped either vertically or horizontally. Typically an end bearer is used to start a panel assembly, the end bearer having a head part for engagement in a female recess 12 of the external sheet 2 of a first panel. The other side of the first panel is then fixed in place by a fastener. This side of the first panel is then engaged with the mating side of a second panel. Construction is continued in this way. After on-site construction, fixing pins may be inserted, and a seal may be applied to ensure the integrity of the joint especially in environments in which the inner wall requires washing, for example in food applications.

Example Panels of the type Figs 1 to 3 with a thickness of 150 mm were tested for fire resistance using the test method described in BS476 part 22 (1987), clauses 5 (wall test) and 9 (ceiling test). The test results are described using the terms insulation and integrity. Both are in units of minutes :- a) Wall Test (Clause 5) Insulation : 47 minutes Integrity : 48 minutes

<Desc/Clms Page number 7>

b) Ceiling Test (Clause 9) Insulation : 52 minutes Integrity : 132 minutes Referring to Fig. 5 there is illustrated a joint between adjacent alternative panels according to the invention. The panels are of similar construction to those of Figs 1 to 4 and like parts are assigned the same reference numerals-In this case, the panels are thinner and the joint between the insulation foam body is smaller.

The invention provides an insulated panel with side edges which are arranged for highly efficient insulation and sealing.

It will be appreciated that the panels may be provided with opposite side edges or two different panels with a similar profile on both side edges may be provided.

The invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail-
