Insulating siding system

1. An insulating siding system comprising a foam sheathing panel, a foam insulating panel, and a siding panel;

the sheathing panel comprising a front surface and a rear surface, the front surface and rear surface being spaced laterally apart from each other, the front surface comprising a first slot, the first slot extending laterally into the sheathing panel and including an upwardly facing channel spaced laterally from the front surface; and

the siding panel comprising a front face, a rear face, and a first downwardly facing channel that extends rearwards, wherein the channel is defined by the rear face, a planar upper channel wall, and a rear wall;

wherein the first slot is sized to receive the rear wall of the first downwardly facing channel; and

wherein the insulating panel extends up to the upper channel wall and is sized and shaped to fit between the rear face of the siding panel, the rear wall, and the front surface of the sheathing panel when the first slot receives the rear wall of the first downwardly facing channel.

2. The insulating siding system of claim 1 , wherein the upwardly facing channel of the first slot has a height that is equal to or greater than a height of the first downwardly facing channel rear wall.

3. The insulating siding system of claim 1 , wherein the first downwardly facing channel extends rearwards from an upper edge of the siding panel.

4. The insulating siding system of claim 1 , wherein the siding panel further comprises a second downwardly facing channel extending rearwards from a lower edge of the siding panel.

5. The insulating siding system of claim 4 , wherein the siding panel further comprises a lower upwardly facing channel located between the lower edge of the siding panel and the second downwardly facing channel.

6. The insulating siding system of claim 5 , wherein the insulating panel has an upper edge and a lower edge, the upper edge of the insulating panel extending into the first downwardly facing channel and the lower edge of the insulating panel extending into the lower upwardly facing channel.

7. The insulating siding system of claim 6 , wherein the first downwardly facing channel is sized so as to contain the upper edge of the insulating panel and a lip of the first slot.

8. The insulating siding system of claim 4 , wherein the second downwardly facing channel comprises a rear wall which is sized so as to be received by the first slot of the sheathing panel.

9. An insulating siding system comprising a foam sheathing panel, a foam insulating panel, and a siding panel;

the sheathing panel comprising a front surface and a rear surface, the front surface and rear surface being spaced laterally apart from each other, the front surface comprising a first slot and a second slot,

each slot comprising an upper surface extending laterally into the front surface, a rear surface extending downwards from the upper surface, a lower surface extending from the rear surface laterally towards the front surface for a lower surface width, a forward surface extending upwards from the lower surface for a forward surface height, a medial surface extending from the forward surface to the front surface for a medial surface width, and a slot entry height between the upper surface and the medial surface; and

the siding panel comprising a front face and a rear face, an upper channel wall extending rearwards from the rear face and having an upper channel wall width, an upper channel rear wall extending downwards from the upper channel wall and having an upper rear wall height, a bottom wall extending rearwards from the rear face, a lower channel front wall extending upwards from the bottom wall, a lower channel top wall extending rearwards from the lower channel front wall and having a lower top wall width, and a lower channel rear wall extending downwards from the lower channel top wall and having a lower rear wall height;

wherein the slot entry height of the first slot is equal to or greater than the upper rear wall height and the slot entry height of the second slot is equal to or greater than the lower rear wall height;

wherein the insulating panel is sized and shaped to fit between the rear face of the siding panel and the front surface of the sheathing panel; and

wherein the insulating panel has an upper edge and a lower edge, the upper edge of the insulating panel extending upwardly past an edge of the upper channel rear wall and the lower edge of the insulating panel extending into a channel formed by the lower channel front wall, the bottom wall, and the front face.

10. The insulating siding system of claim 9 , wherein the insulating panel has an upper edge width, and the upper channel wall width is equal to or greater than the sum of the insulating panel upper edge width and the medial surface width.

11. The insulating siding system of claim 9 , wherein the lower top wall width is equal to or greater than the upper channel wall width.

12. The insulating siding system of claim 9 , wherein the ratio of the slot entry height to the forward surface height for each slot is independently from about 1:2 to about 2:1.

13. The insulating siding system of claim 9 , wherein the upper channel wall extends rearwards at an upper edge of the siding panel, and the bottom wall extends rearwards at a lower edge of the siding panel.

14. An insulating siding system comprising a sheathing panel, an insulating panel, and a siding panel;

the sheathing panel comprising a front surface and a rear surface, the front surface and rear surface being spaced laterally apart from each other, the front surface comprising a first slot, the first slot extending laterally into the sheathing panel and including an upwardly facing channel spaced laterally from the front surface; and

the siding panel comprising a front face, a rear face, a first downwardly facing channel that extends rearwards from an upper edge of the siding panel, wherein the channel is defined by the rear face, a planar upper channel wall, and a rear wall, a second downwardly facing channel extending rearwards from a lower edge of the siding panel, and a lower upwardly facing channel located between the lower edge of the siding panel and the second downwardly facing channel;

wherein the first slot is sized to receive the rear wall of the first downwardly facing channel;

wherein the insulating panel extends up to the upper channel wall and is sized and shaped to fit between the rear face of the siding panel, the rear wall, and the front surface of the sheathing panel when the first slot receives the rear wall of the first downwardly facing channel;

wherein the insulating panel has an upper edge and a lower edge, the upper edge of the insulating panel extending into the first downwardly facing channel and the lower edge of the insulating panel extending into the lower upwardly facing channel; and

wherein the first downwardly facing channel is sized so as to contain the upper edge of the insulating panel and a lip of the first slot.
