a plurality of studs; and a sheathing board attached to the plurality of studs and forming the outer face of the inner wall.
- 4. The cavity wall construction of claim 1 further comprising:
a flashing covering a lowermost portion of the outer face of the inner wall and extending along the foundation to span the cavity and underlay at least a portion of the outer wall.
- 5. The cavity wall construction of claim 1 further comprising:
a mortar collector positioned atop the foundation and in the cavity proximate a base of the inner and outer walls.
- 6. The cavity wall construction of claim 1 further comprising:
a weep area positioned in the masonry material proximate the foundation.
- 7. The cavity wall construction of claim 1 wherein the corrugated board further comprises:
a plurality of generally vertical chambers and the channels are likewise generally vertical and each channel has a spine juxtaposed to the outer face of the inner wall and interposed between an adjacent pair of the generally vertical chambers.
- 8. The cavity wall construction of claim 7 further comprising:
a self-sealing tape joining the spine of each channel to the inner wall.
- 9. The cavity wall construction of claim 1 further comprising:
a plurality of anchors projecting through the corrugated board and into the inner wall and being coupled to the outer wall.
- 10. The cavity wall construction of claim 1 further comprising:
a self-sealing tape joining each channel to the inner wall; and a plurality of anchors projecting through the corrugated board and into the inner wall and being coupled to the outer wall; wherein the self-sealing tape provides a seal around each anchor to thereby inhibit transfer of moisture to the inner wall.
- 11. A cavity wall construction comprising:
a foundation; an inner wall extending upwardly from the foundation, the inner wall including a plurality of studs and a sheathing board attached to the plurality of studs and forming the outer face of the inner wall; an outer wall extending upwardly from the foundation, having an inner face confronting an outer face of the inner wall and being generally parallel to and spaced from the inner wall to define a cavity therebetween; wherein the outer wall is comprised of courses of masonry material held together with mortar between the adjacent courses; a vapor barrier substantially covering the outer face of the inner wall to inhibit moisture from penetrating into the inner wall; a flashing covering a lowermost portion of the outer face of the inner wall and extending along the foundation to span the cavity and underlay at least a portion of the outer wall; a weep area positioned in the masonry material proximate the foundation; a mortar collector positioned atop the foundation and in the cavity proximate a base of the inner and outer walls; a corrugated board positioned between the inner and outer walls and covering a substantial portion of the outer face of the inner wall to inhibit the mortar from contacting the inner wall; a plurality of channels in the corrugated board permitting the escape of fluid trapped in the cavity; a self-sealing tape joining each channel to the inner wall; and a plurality of anchors projecting through the corrugated board and into the inner wall and being coupled to the outer wall; wherein the self-sealing tape provides a seal around each anchor to thereby inhibit transfer of moisture to the inner wall.
- 12. The cavity wall construction of claim 11 wherein the corrugated board further comprises:
a plurality of generally vertical chambers and the channels are likewise generally vertical and each channel has a spine juxtaposed to the outer face of the inner wall and interposed between an adjacent pair of the generally vertical chambers.
- 13. A method of constructing a cavity wall structure comprising the steps of:
erecting an inner wall having an outer face and projecting upwardly from a foundation; mounting a corrugated board to the outer face of the inner wall to cover a substantial portion of the outer face of the inner wall; and erecting an outer wall extending upwardly from the foundation, the outer wall having an inner face confronting the outer face of the inner wall and being generally parallel to and spaced from the inner wall to define a cavity therebetween, wherein the outer wall is comprised of courses of masonry material held together with mortar between the adjacent courses; wherein the corrugated board inhibits the mortar from the outer wall from contacting the inner wall and thereby inhibiting damage to the inner wall and inhibit transfer of moisture to the inner wall.
- 14. The method of claim 13 further comprising:
anchoring the outer wall to the inner wall.
- 15. The method of claim 14 wherein the anchoring further comprises:
inserting a plurality of anchors through the corrugated board and into the inner wall; and embedding a portion of each of the anchors in the mortar material.
- 16. The method of claim 15 further comprising:
sealing around each of the anchors projecting through the corrugated board and into the inner wall.
- 17. The method of claim 16 further comprising:
attaching the corrugated board to the inner wall with a mastic layer, wherein the mastic layer also performs the sealing step.
- 18. The method of claim 13 further comprising:
providing for fluid circulation and escape from the cavity between the inner and outer walls in channels formed in the corrugated board, the channels being oriented generally vertically and extending substantially the entire height of the corrugated board.
- 19. The method of claim 13 further comprising:
positioning a mortar collector proximate the foundation in the cavity to collect excess mortar escaping from between the courses of masonry; substantially covering the outer face of the inner wall with a vapor barrier, the vapor barrier being situated between the inner wall and the corrugated board; and covering a lowermost portion of the outer face of the inner wall with a flashing extending along the foundation to span the cavity and underlay at least a portion of the outer wall.
- 20. A method of constructing a cavity wall structure comprising the steps of:
erecting an inner wall having an outer face and projecting upwardly from a foundation; adding a corrugated board to the outer face of the inner wall to cover a substantial portion of the outer face of the inner wall; erecting an outer wall extending upwardly from the foundation, the outer wall having an inner face confronting the outer face of the inner wall and being generally parallel to and spaced from the inner wall to define a cavity therebetween, wherein the outer wall is comprised of courses of masonry material held together with mortar between the adjacent courses; wherein the corrugated board inhibits the mortar from the outer wall from contacting the inner wall and thereby inhibiting damage to the inner wall and inhibit transfer of moisture to the inner wall; providing for fluid circulation and escape from the cavity between the inner and outer walls in channels formed in the corrugated board, the channels being oriented generally vertically and extending substantially the entire height of the corrugated board; inserting a plurality of anchors through the corrugated board and into the inner wall; embedding a portion of each of the anchors in the mortar; sealing around each of the anchors projecting through the corrugated board and into the inner wall; attaching the corrugated board to the inner wall with a mastic layer, wherein the mastic layer also performs the sealing step; positioning a mortar collector proximate the foundation in the cavity to collect excess mortar escaping from between the courses of masonry material; substantially covering the outer face of the inner wall with a vapor barrier, the vapor barrier being situated between the inner wall and the corrugated board; and covering a lowermost portion of the outer face of the inner wall with a flashing extending along the foundation to span the cavity and underlay at least a portion of the outer wall.
