English Abstract

An insulated vent chute and blocking assembly which can be inserted between adjacently disposed roof rafters of a building construction having a pitched or flat roof, the roof supported by a building wall. The assembly comprises: a generally flexible insulated body having a roof facing surface, an attic space facing surface, the surfaces spaced apart from each other to define a pair of longitudinal rafter facing sides, a top and a bottom transverse end, the ends connecting the sides; and a reflective substrate covering the attic space facing surface, the substrate for reflecting heat away from the attic space facing surface and back into attic insulation. The assembly is fabricated from a flexible insulated material, and can assume an arcuate form in embodiments when the body is inserted between adjacently disposed roof rafters in the building construction with a pitched or flat roof such that the bottom transverse end can contact the top of the building wall.


French Abstract

Assemblage de glissière dévacuation et de blocage pouvant être inséré entre les éléments de la toiture dun immeuble doté dun toit plat ou à forte pente, le toit est soutenu par un mur de construction. Lassemblage contient : une structure insonorisée flexible dotée dune surface exposée au toit, dune surface exposée à un espace mansardé, les surfaces sont espacées afin de définir deux côtés longitudinaux exposés aux toits, une extrémité transversale supérieure et inférieure, les extrémités sont reliées aux côtés, et un substrat réfléchissant recouvre la surface exposée à lespace mansardé, le substrat permet dévacuer la chaleur de la surface exposée à lespace mansardé et disoler la mansarde. Lassemblage est fabriqué à partir de matériaux isolés flexibles, et présente une forme précise lorsque la structure est insérée entre les parties du toit adjacentes au sein de la construction de bâtiments dotée dun toit plat ou à forte pente de manière à ce que lextrémité transversale inférieure soit en contact avec la partie supérieure du mur de construction.

assembly is fabricated from a flexible insulated material effective to assume
an arcuate
form when the body is inserted between adjacently disposed roof rafters in the
building
construction with a pitched roof and the bottom transverse end contacts on the
top of the
building wall; and
a reflective substrate covering the attic space facing surface, the substrate
for
reflecting heat away from the attic space facing surface and back into attic
insulation.
2. The assembly of claim 1 wherein the reflective substrate comprises a tab
that extends
beyond the transverse width of the body, the tab for sealingly attaching the
assembly to
adjacent roof rafters.

3. The assembly of claim 2 wherein the tab extends along entire length of the
body.
4. The assembly of claims 2 or 3 wherein the reflective substrate comprises a
tab that
extends beyond the longitudinal length of the body, the tab for sealingly
attaching the
assembly to the top of the building wall.

5. The assembly of any one of claims 1 to 4 wherein the material of the body
comprises a
foam material.

6. The assembly of claim 5 wherein the foam material is a semi-rigid foam or a
rigid foam.
7. The assembly of claim 6 wherein the semi-rigid foam or the rigid foam
comprises a
transverse cut formed in the attic space facing surface, the transverse cut
for allowing the
assembly to assume an arcuate form.


-19-




8. The assembly of claim 7 wherein the transverse cut is located proximate to
the bottom
transverse end.

9. The assembly of claim 7 or 8 wherein the transverse cut is about 5 inches
from the bottom
transverse end.

10. The assembly of claim 5 wherein the semi-rigid foam or the rigid foam
comprises a
plurality of transverse cuts formed in the attic space facing surface, the
plurality of
transverse cuts for allowing the assembly to bend.

11. The assembly of claim 10 wherein the plurality of transverse cuts are
about 5 inches from
the bottom transverse end.

12. The assembly of claim 10 or 11 wherein the plurality of transverse cuts
are about 5 inches
from the bottom transverse end and extend to about 10 inches from the bottom
transverse
end.

13. The assembly of any one of claims 1 to 12 wherein the longitudinal length
is less than
about 4 feet.

14. The assembly of any one of claims 1 to 13 wherein the longitudinal length
is between 3
and 4 feet.

15. The assembly of any one of claims 1 to 14 wherein the transverse width is
about 22
inches.

16. The assembly of any one of claims 1 to 15 wherein the R-value of the body
is at least
about R-10.

17. The assembly of any one of claims 1 to 15 wherein the R-value of the
assembly is made
to match that of the R-value of the building wall.

18. The assembly of any one of claims 1 to 17 wherein the R-value of the
assembly is
between about R-10 to about R-26.

-20-




19. The assembly of any one of claims 1 to 17 wherein the R-value of the
assembly is about
R-20 or higher.

20. The assembly of any one of claims 1 to 19 wherein the thickness of the
body between the
roof facing surface and the attic space facing surface is less than about 3
inches.

21. The assembly of claim 20 wherein the thickness is between 2 and 3 inches.
22. The assembly of claim 20 wherein the thickness is about 2 inches.

23. The assembly of any one of claims 1 to 22 wherein the reflective substrate
is bonded to
the attic space facing surface.

24. The assembly of claim 23 wherein the reflective substrate comprises a
reflective film.
25. The assembly of claim 24 wherein the reflective film is aluminum.

26. The assembly of claim 24 wherein the reflective film is a polymeric
material.

27. The assembly of any one of claims 23 to 26 wherein the reflective film is
made from
moisture resistant material.
28. A method for making a unitary insulated vent chute and blocking assembly,
the method
comprising:
providing a generally flexible insulated body having a roof facing surface, an
attic
space facing surface, the surfaces spaced apart from each other to define a
pair of
longitudinal rafter facing sides, a top and a bottom transverse end, the ends
connecting the

layering the reflective substrate to the body so that the reflective substrate
covers the
attic space facing surface.

-21-




29. The method of claim 28 further comprising the step of:
forming a transverse cut in the attic space facing surface before applying the
bonding
material.

30. The method of claim 29 wherein the transverse cut is located proximate to

are about 5 inches
from the bottom transverse end and extend to about 10 inches from the bottom
transverse
end.

35. A method for establishing and maintaining air flow under a pitched or flat
roof of a
building construction between a soffit region and an attic space, the building
construction
comprising an exterior wall, a ceiling supported by the wall, a roof including
a plurality
of rafter trusses supported by the wall where each truss includes ceiling
joist segments
and two intersecting, but opposed, rafter segments, and a roof deck supported
by the
rafter segments, the method comprising:
providing a unitary insulated vent chute and blocking assembly as defined in
any one
of claims 1 to 27;
sliding the assembly between adjacently disposed rafter segments so that the
reflective substrate faces inwards and towards the building interior and so
that the roof
facing surface of the body faces outwards and towards the roof;
orienting the bottom transverse end so that it contacts the top of the wall;
-22-




bending the assembly so that the body assumes an arcuate form and forms an
angle
relative to the balance of the assembly that is approximates to the pitch of
the roof; and
securing the assembly to adjacently disposed rafter segments.
