Construction product having a frame with multi-functional thermal break
View Patent ↗A construction product such as a window or door includes a multi-functional thermal break. The thermal break serves to contact and support elements of the frame of the construction product. The thermal break also provides one or more additional structural functions for the construction product.
1. A construction product, comprising:
a frame having a frame element, the frame element comprising:
an interior jamb portion fabricated from a metal material, the interior jamb portion having an outer horizontally-extending projection and an outer vertically-extending projection and being deficient of a central horizontally-extending projection;
an exterior jamb portion fabricated from a metal material, the exterior jamb portion having an outer horizontally-extending projection and an outer vertically-extending projection and being deficient of a central horizontally-extending projection; and
a thermal break having a horizontally-extending projection that alone forms a central horizontally-extending structural support of the frame element, wherein the thermal break is only fabricated from an insulating material, wherein the thermal break directly connects the interior jamb portion with the exterior jamb portion at a single engagement position on each of the interior jamb portion and the exterior jamb portion, and wherein the thermal break supports the interior jamb portion and the exterior jamb portion;
a first moveable sash window having a first stile, wherein the first moveable sash window slides up and down within the frame; and
a first moveable support member that supports the first moveable sash window in multiple positions,
wherein the thermal break is multi-functional:
(a) the thermal break provides an insulating function so as to limit thermal conduction between the interior jamb portion and the exterior jamb portion, and
b) the thermal break alone cooperates with the interior jamb portion to (1) define at least a portion of a first cavity that accepts the first moveable support member, and (2) define a track for the first moveable support member to slide up and down within the frame.
2. The construction product of claim 1 , wherein the first moveable support member comprises a counterbalance mechanism, tilt shoe or pivot bar, and the first moveable support member is operatively connected to the first moveable sash window and supports the first moveable sash window when the first moveable sash window is in an open position.
3. The construction product of claim 1 , further comprising:
a second moveable sash window having a second stile, wherein the second moveable sash window slides up and down within the frame; and
a second moveable support member that is operatively connected to the second moveable sash window and supports the second moveable sash window when the second moveable sash window is in an open position,
wherein the thermal break alone cooperates with the exterior jamb portion to (1) define at least a portion of a second cavity that accepts the second moveable support member, and (2) define a track for the second moveable support member to slide up and down within the frame.
4. The construction product of claim 1 , wherein the interior jamb portion of the frame element also defines a portion of the first cavity.
5. The construction product of claim 3 , wherein:
the interior jamb portion of the frame element also defines the first cavity, and
the exterior jamb portion of the frame element also defines the second cavity.
6. The construction product of claim 1 , further comprising:
a first weather strip that contacts the first stile of the first moveable sash window and the thermal break;
a second moveable sash window having a second stile, wherein the second moveable sash window slides up and down within the frame; and
a second weather strip that contacts the second stile of the second moveable sash window and the thermal break.
7. The construction product of claim 1 further comprising:
a weather-resistant material that extends from the first stile;
wherein the thermal break includes an extended member, and
wherein the weather-resistant material also contacts the extended member.
8. The construction product of claim 1 wherein:
the thermal break comprises a first member that connects and supports the interior jamb portion and the exterior jamb portion, and a second member that defines at least a portion of the first cavity, and
the first member extends from the second member in a substantially perpendicular direction.
9. The construction product of claim 1 , wherein:
the metal frame comprises aluminum; and
the thermal break comprises a polymer.
10. The product of claim 1 , wherein the thermal break is structured to provide a U- shaped wall that defines the portion of the first cavity.
