Architectural terrace door
The threshold system includes a first support member secured to a walking surface, a second support member secured to the walking surface, and a thermal break joining the first support member and the second support member. A first ramp is removably coupled to the first support member. A second ramp is removably coupled to the second support member.
1. A threshold system, comprising:
a first support member secured to a walking surface;
a second support member secured to the walking surface;
a thermal break joining the first support member and the second support member;
a first ramp removably coupled to the first support member;
a second ramp removably coupled to the second support member;
a first flange extending outwardly from the first support member under the first ramp in a spaced parallel relationship to the walking surface; and
a second flange extending outwardly from the second support member under the second ramp in a spaced parallel relationship to the walking surface.
2. The threshold system of claim 1 , comprising a first gasket disposed between the first support member and the second support member, the first gasket extending upwardly from the first support member and the second support member.
3. The threshold system of claim 1 , comprising a first caulk line disposed between the first flange and the walking surface.
4. The threshold system of claim 3 , wherein the first ramp conceals the first caulk line.
5. The threshold system of claim 3 , wherein selective removal of the first ramp facilitates visual inspection of the first caulk line.
6. The threshold system of claim 3 , wherein the first caulk line prevents infiltration of water under the first support member.
7. The threshold system of claim 1 , comprising a second caulk line disposed between the second flange and the walking surface.
8. The threshold system of claim 7 , wherein the second ramp conceals the second caulk line.
9. The threshold system of claim 7 , wherein selective removal of the second ramp facilitates visual inspection of the second caulk line.
10. The threshold system of claim 7 , wherein the second caulk line prevents infiltration of water under the second support member.
11. The threshold system of claim 1 , wherein the first support member and the second support member are coupled to the walking surface without removal of an upper face of the walking surface.
12. The threshold system of claim 1 , comprising a door assembly disposed above at least one of the first support member and the second support member.
13. The threshold system of claim 12 , wherein the first gasket seals against the door assembly when the door assembly in in a closed position.
14. The threshold system of claim 12 , wherein the door assembly includes a second gasket extending downwardly from the door assembly.
15. The threshold system of claim 14 , wherein the second gasket seals against at least one of the first ramp and the first support member when the door assembly is in a closed position.
16. The threshold system of claim 14 , wherein the second gasket is elastically deformable and folds downwardly to facilitate passage of objects thereover.
