Abstract

The insulating panel for a building structure has a rigid insulating body and two opposed outer surfaces. It is characterized in that it comprises a plurality of framing members made of a high strength material embedded in the body, each framing member being provided with anchor means for securely holding it in the body and being adapted for receiving and holding at least one fastener and thereby securing the panel to the building structure. An insulating panel according to the present invention, on one hand allows a very large range of use for such a panel, and on the other hand, allows a very rapid installation at a low cost. Such an insulating panel may be used for insulating a wall as well as a ceiling or a roof or a floor.

Claims

1. An insulating panel for a building structure, the panel comprising:

a rigid body made of thermoplastic foam;

two opposed outer surfaces; and

a plurality of spaced-apart elongated framing members embedded in said body, each framing member having a U-shaped cross-section with a bottom surface parallel to both said outer surfaces and interconnecting a pair of oppositely disposed arms extending into the body,

each of said arms being provided along the framing member with a plurality of holes filled with foam of the body and thereby anchoring said framing member in said body; and

each of said bottom surface being adapted along its length to receive and hold a plurality of fasteners to secure the panel to the building structure and to hang and object to the panel.

2. An insulating panel as claimed in claim 1, wherein the bottom surface of each framing member is flush with one of said outer surfaces of the panel.

3. An insulating panel as claimed in claim 2, wherein the bottom surface of each framing member is provided with an elongated slot adapted to receive said at least one fastener.

4. An insulating ceiling structure for installation under a load-bearing structure of a building, the insulating ceiling structure comprising:

a first layer of panels as claimed in claim 2, the bottom surface of the framing members of each of said panels opposing the load-bearing structure; and

a first set of fasteners for securing the panels of the first layer to the load-bearing structure via the framing members.

5. An insulating ceiling structure as claimed in claim 4, further comprising:

a second layer of panels similar to the panels of the first layer, the bottom surface of the framing members of each of said panels of the second layer opposing the first layer of panels; and

a second set of fasteners for securing the panels of the second layer via the framing members thereof to the framing members of the first layer.

6. An insulating ceiling structure as claimed in claim 5, further comprising:

a layer of sheathing comprising a plurality of sheathing panels for covering the second layer of panels; and

a third set of fasteners for securing said sheathing panels to the second layer via the framing members thereof.

7. An insulating ceiling structure as claimed in claim 6, further comprising:

an upper layer of plywood sheet lying between the load-bearing structure and the first layer of panels.

8. An insulating ceiling structure as claimed in claim 7, wherein, the framing members of each insulating panels are parallel with each other.

9. An insulating ceiling structure as claimed in claim 8, wherein the insulating panels of the second layer are disposed so that the framing members thereof are perpendicular to the framing members of the panels of the first layer.

10. An insulating ceiling structure as claimed in claim 9, wherein the first, second and third set of fasteners consist of screws.

11. An insulating ceiling structure as claimed in claim 4, further comprising:

an upper layer of plywood sheet lying between the load-bearing structure and the first layer of insulating panels;

a layer of sheathing comprising a plurality of sheathing panels for covering the first layer of insulating panels; and

another set of fasteners for securing said sheathing panels to the first layer of panels via the framing members thereof.

12. A method for building and insulating a ceiling structure under a load-bearing structure of a building, the method comprising the step of:

a) fixing a first layer of insulating panels as claimed in claim 2 to the load-bearing structure by means of a first set of fasteners inserted in the framing members of the panels, the bottom surface of the framing members of each of said panels opposing the load-bearing structure.

13. A method as claimed in claim 12, further comprising the step of:

b) fixing to the framing members of the first layer a second layer of insulating panels similar to the insulating panels of the first layer by means of a second set of fasteners inserted in the framing members of the panels of the second layer, the bottom surface of the framing members of each of said panels of the second layer opposing the first layer of panels.

14. A method as claimed in claim 13, further comprising the step of:

c) fixing a layer of sheathing panels to the second layer of insulating panels; and

before step a), fixing an upper layer of plywood sheet to the load-bearing structure, the upper layer lying between the load-bearing structure and the first layer of insulating panels.
