Integrated Sill, Threshold & Drainage Details

Flush and integrated sill solutions designed around the door system, finished floor levels and project requirements for a clean transition between inside and out.

Overview

The detail that makes the opening feel seamless.

An integrated sill lowers the visual break between the internal floor and the outdoor area, so the opening reads as a continuation of the room. At Datco, we look at the sill as part of the whole opening — the door system, the floor levels and the surrounding construction all influence what can be achieved.

Integrated sill options are available with suitable sliding and architectural door systems. Threshold heights need to be considered alongside internal and external finishes early, because the drainage, falls and surrounding construction details all matter to how the finished detail performs.

The best time to discuss it is before slab levels, waterproofing and finished floor levels are locked in. In a renovation, existing slab levels and floor build-up will determine what can practically be achieved.

Relevant sill and system information can be coordinated with the builder or project team where required within the agreed scope. The building waterproofing design, slab design, structural engineering, certification and surrounding drainage works remain with the relevant qualified professionals on the project.
