Building panel assembly and method of manufacturing
Building panel assemblies for use in the construction of new homes, commercial buildings and extensions having rectangular structural insulated panel (SIP) ( 10 ), comprises a pair of spaced-apart containment boards ( 12′,12″ ) an inner insulating core ( 13 ) and a low profile peripheral external rigid frame ( 14 ), preferably of metal, e.g. steel, extending around the entire periphery of the spaced-apart boards ( 12′,12″ ).
1. A building panel assembly comprising a pair of spaced-apart containment boards, separated by an inner insulating core, said inner insulating core comprising one or more preformed body around which a curable insulating foam is introduced;
at least one peripherally disposed channel for receiving a rigid frame, said channel spaced apart from and disposed between the containment boards;
wherein the rigid frame defining a pair of spaced-apart longitudinal channels extending around the periphery of the panel and into the space between the spaced-apart part of containment boards;
at least one conduit disposed adjacent to and between at least one containment board and the inner insulating core; and
wherein each preformed body comprised a plurality of alignment members disposed in order to maintain its position away from the at least one containment board.
2. A building panel assembly as claimed in claim 1 wherein the alignment members comprise one or more protrusions extending from the surface of the preformed body.
3. A building panel assembly as claimed in claim 1 having two conduits.
4. A building panel assembly as claimed in claim 1 , in which the containment boards are selected from oriented strand board, cement particle board magnesium oxide wall board, plywood, pressure treated plywood, steel, aluminium, fibre reinforced plastics, or metal, or composite sheeting.
5. A building panel assembly as claimed in claim 1 , in which the inner insulating core is comprised of expanded polystyrene foam, extruded polystyrene foam or polyurethane foam.
6. A building panel assembly as claimed in claim 1 wherein the one or more preformed body is solid.
7. A building panel assembly as claimed in claim 1 wherein the one or more preformed body accounts for 95% or less of an internal volume of the cavity between the containment boards.
8. A building panel assembly as claimed in claim 7 wherein the one or more preformed body accounts for 25-50% of the internal volume of the cavity between the containment boards.
9. A building panel assembly as claimed in claim 8 wherein the one or more preformed body accounts for 30% of the internal volume of the cavity between the containment boards.
10. A building panel assembly as claimed in claim 1 wherein the curable insulating foam accounts for h remaining volume of the inner insulating core.
11. A building panel assembly as claimed in claim 1 wherein the curable insulating foam is heat and/or UV cured.
