Door Threshold Selector

Door Threshold Selector

Tell us the door location, whether the route must be step-free and the level change at the opening — and we'll recommend the right threshold (saddle, ramped, aluminium seal, zero/flush or weather-bar), with the accessible ≤12mm RPwD/NBC rule flagged.

Your opening

Faces weather — needs a water/draught barrier and outward drainage slope. No accessibility constraint; weather and durability lead the choice. Indicative India 2026 — confirm the detail with your carpenter / fitter on site; measure twice.

Recommended threshold

Finned weather-bar

Suitability 0/100·500–₹2,800 / door (ex-GST)

A finned aluminium bar with a drip and gasket built for exposed entrances — sheds wind-driven rain. It carries an upstand, so it is not a barrier-free option.

  • Finned weather-bar is purpose-built for exposed entrances.

Option suitability scores

Higher is better for your inputs. Terracotta is the top pick.

All threshold types, ranked for your door

Scored against your location, accessibility need and level change. Indicative supply + fit per door, ex-GST.

01Finned weather-bar78/100

A finned aluminium bar with a drip and gasket built for exposed entrances — sheds wind-driven rain. It carries an upstand, so it is not a barrier-free option.

500–₹2,800 / door · typical upstand 18mm

02Stone / timber saddle66/100

A raised strip of granite, marble or hardwood across the opening — durable, classic, and a clean water/dust stop for wet and external doors.

350–₹2,200 / door · typical upstand 25mm

03Ramped / bevelled56/100

A saddle chamfered to a gentle slope so a small level change rolls over — bevel anything above 6mm; keep the upstand ≤12mm for an accessible route.

450–₹2,600 / door · typical upstand 12mm

04Aluminium strip + seal42/100

A low aluminium track with a brush/rubber gasket — seals draught, dust and sound on internal and entrance doors with a slim, neat profile.

300–₹1,400 / door · typical upstand 10mm

05Zero / flush threshold32/100

No upstand at all — the floor runs through level. The gold standard for accessibility; externally it needs a drainage channel + slope to stay watertight.

600–₹4,000 / door · typical upstand 0mm

Detail the threshold right

DesignAI helps you waterproof a wet-area saddle, keep an entrance dry, and hold an accessible route within ≤12mm — and matches the threshold to your floor finish.

Notes & assumptions

  • Accessible rule: for a step-free / barrier-free route, the upstand should be flush or ≤12mm, bevelled if it exceeds 6mm (RPwD Act / NBC Harmonised Guidelines). Keep free egress clear — never trap an exit behind a high sill.
  • External & wet areas: a flush / zero threshold outdoors needs a graded floor and a channel drain to stay watertight; in wet areas use a granite saddle with sealant over a waterproofing membrane and a WPC / PVC / RCC frame, with anti-termite DPC at the frame base.
  • Costs: figures are indicative supply + fit per door, ex-GST; add 18% GST on materials and works. Prices vary by stone / profile, city and vendor.
  • This is a guidance tool, not a substitute for a skilled carpenter or site engineer. Indicative — confirm with your carpenter / fitter on site; measure twice.
