Door Sills

 

We offer a full spectrum of solutions for our swing and sliding sill conditions. Most are custom solutions for the variety of conditions we have experienced in our projects. Each project's requirements influence the final design and we document this during the shop drawing process. Below are some current design options.

We offer a full spectrum of solutions for our swing and sliding sill conditions. Most are custom solutions for the variety of conditions we have experienced in our projects. Each project's requirements influence the final design and we document this during the shop drawing process. Below are some current design options.

Whenever possible sill and threshold conditions are developed to create the minimal transition between interior and exterior walking surfaces. The majority of our projects have cut or cast stone threshold treatments. Extruded sill solutions can be introduced if needed.

Outswing doors typically have a step down from interior to exterior. Inswing door sills typically need a raised threshold to prevent water blowing in. Sliding doors have top hung floor guides that are flush to finish floor and offer the most seamless transition while still acting as a water return.  Bottom rolling sliding doors have a water return guide track that sits a subtle 3/16" above finish floor for a near flush transition.

Whenever weather exposure is a concern, drain slots should be added to the inswing sill designs. Extreme weather environments need more extreme measures and coordination with waterproofing consultants.

Out swing doors have a step down between exterior and interior floor surfaces. Using the stainless steel "L" tie as a transition between surfaces creates a natural 1/2" step. This is a good water detail for typical weather conditions.

The "L" ties are available in a series of sizes to increase the space below finish floor for stone build up. When needed the tie can remain fully concealed by using a flat bar instead of the "L" tie. See shop drawings.


 

Inswing Sills
 

Inswing doors need design development to make sure the raised portion of the threshold offers the best walk through solution in concert with the best water protection solution.

The inswing sill has a raised threshold to make sure that there is good contact with the bottom weatherstrip sweeps. The higher the raised portion of the sill the better the clearance of the door as it opens in over the finished floor. See shop drawings.

Any intended use of throw rugs on the interior would be a consideration in developing the overall height of the threshold.

Top Hung Sills

When top hung sliding door hardware is used, the bottom track is a flush set guide track. Each guide track has drain tubes plumbed into the bottom to move away excess water.

The combination of multiple door tracks creates a multiple drain opportunity. At the interlock stiles of a multiple door set, an additional interlock drain is added to further carry away water.

Extreme weather exposures should be evaluated for water drainage. Additional drains can be added on standard tracks, as well as additional drainage slots on the inside of the entire track system. Coordination with waterproofing consultants is recommended in all unprotected exposures. See details.


 

Bottom Rolling Slider Sill (lift slide similar)
 

When bottom rolling sliding door hardware is used, the bottom track is set 3/16" above finish floor. Each track is coupled with a drain slot along the length of the track. Drain tubes are plumbed into the bottom to move away excess water.

Similar to the top hung tracks, the combination of multiple door tracks creates a multiple drain opportunity. At each of the interlock stiles of a multiple door set, an additional interlock drain is added to further draw off water.

Extreme weather exposures should be evaluated for water drainage. Additional drains can be added on standard tracks, as well as additional drainage slots on the inside of the entire track system. Coordination with waterproofing consultants is recommended in all unprotected exposures. See drawings.

Folding Door Sills

Folding doors have a "U" track along the bottom of the door set that is used to guide the rollers at the pivoting doors. These tracks are fit with drain tubes to move away excess water.

Outswing folding doors also have a 1/2" step from interior finish floor to exterior floor surface. This step helps with the water proofing at the sill. Even with this step, in extreme weather exposures special consideration should be given to moving excess water away from the opening. See drawings.


 

Pivot Door Sills
 

Pivot door sill conditions are similar to inswing doors. Because the door bottom swings in over the interior finish floor, the final design should give consideration to floor clearance.

The sill will need a raised threshold for the weatherstrip to sweep onto, and enough height for finish floor clearance.

For pivot doors, special consideration is needed to provide removable sill sections and access to the hydraulic floor pivot in the event of maintenance. An removable cover is also used in close proximity to the pivot post to allow access to adjust closer speed and hold open. See drawings.
