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 method of constructing a threshold system, the method comprising:
coupling a first support member to a walking surface, the first support member comprising a first flange that extends laterally from the first support member;
sealing the first support member to the walking surface via a first caulk line;
coupling a second support member to the walking surface, the second support member comprising a second flange that extends laterally from the second support member;
sealing the second support member to the walking surface via a second caulk line;
concealing the first caulk line with a first ramp that is removably coupled to the first support member such that the first flange extends laterally under the first ramp;
concealing the second caulk line with a second ramp that is removably coupled to the second support member such that the second flange extends laterally under the second ramp; and
coupling a first gasket 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.
2. The method of claim 1 , comprising:
hingedly coupling a door assembly to the threshold system;
sealing the first gasket against the door assembly when the door assembly is in a closed position; and
sealing a second gasket that extends downwardly from the door assembly against at least one of the first support member and the first ramp when the door assembly is in the closed position.
3. The method of claim 1 , comprising folding the first gasket downwardly to facilitate passage of objects thereover.
4. The method of claim 1 , comprising visually inspecting the first caulk line and the second caulk line via selective removal of the first ramp and the second ramp.
5. The method of claim 1 , wherein the first caulk line prevents infiltration of water under the first support member.
6. The method of claim 1 , comprising a second caulk line disposed between the second support member and the walking surface.
7. The method of claim 1 , wherein the second caulk line prevents infiltration of water under the second support member.
8. The method 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.
