Window Design Software

Mobile-first window design software for fabricators, architects, and fitters. Draw any window configuration with millimetric accuracy — no CAD training required.

Professional Window Design on a Phone

Purpose-built for fenestration work — faster than AutoCAD, more accurate than pen & paper.

1

Multi-Panel Configurations

Design single, double, triple, and four-panel windows. Add transoms, mullions, fanlights, and sidelights with drag-and-drop controls that produce dimensionally accurate drawings.

2

Opening Types Library

Casement, tilt-turn, sash, top-hung, side-hung, French, pivot, fixed, and tilt-only — all built in. Each opening applies the correct hardware, seals, and airflow logic automatically.

3

Real-Time Dimensions

Every line of your drawing carries a live dimension. Change frame width and glass sizes, mullion positions, and hardware offsets update in real time — no manual recalculation.

4

Export to Production

Export cut lists, glass schedules, and technical drawings as PDF or CSV. Feed straight into your saw list, glass supplier order, and production floor with zero re-entry.

Frequently Asked Questions

Do I need CAD experience to use it?
No. Doorwin is designed for window installers and fabricators, not draughtsmen. If you can use a phone, you can design a window. Most users are producing production-ready drawings within an hour.
What window configurations are supported?
Any combination of casement, tilt-turn, sash, French, and fixed panels — including arched, angled, and bay/bow configurations up to 6 panels wide.
Can I design curtain walls and commercial glazing?
Stick curtain wall systems and commercial storefronts up to 4m × 4m are supported, with mullion and transom dimensioning, glass infill zones, and structural calculation exports.
Does it produce manufacturing drawings?
Yes. Each window generates a technical drawing with frame dimensions, glass sizes, hardware positions, and cut list — ready for the workshop or your sub-contract fabricator.
