About the App

Made-to-Measure Aluminium Sills | Built for Certainty

Cills.ie was built to solve a single, expensive problem in construction: custom aluminium products arriving on site and failing to fit. By shifting the entire measurement process into a smart 3D app, we remove translation errors entirely.

The Problem

Aluminium Sills for Contractors

In construction, a 15mm error is the difference between a successful handover and a week-long delay. For years, tradespeople scribbled dimensions on timber offcuts, dictated RAL codes over loud phone calls, and hoped the person on the other end understood.

Aluminium is unforgiving. Once it is cut, it cannot be stretched. A wrong cill goes into the skip, the project is delayed, subcontracted window installers stand idle, and retention payments slip.

We built Cills.ie to replace this guesswork with absolute digital certainty. By unifying guided site measuring, direct machine manufacturing, and professional fitting under one process, we protect your project schedules and your margins.

// The Unified Service

Cills is the only company that measures on site, manufactures to the exact specs, and installs the final panels. One workflow. One partner. Zero handoff errors.

The Architecture

  • 01

    Guided site measurements

    The app prompts you for every dimension, reveal detail, and clearance factor while you stand at the window opening.

  • 02

    Live 3D configuration

    Preview the custom profiles in real-time. What you see on screen is exactly what gets machined in production.

  • 03

    Direct machine link

    Your measurements transfer directly to CNC cutting and bending machinery. No paper, no emails, no transcription errors.

  • 04

    Measure, Make, Fit

    Book technicians to measure on site, let our machines manufacture the cills, and have our team fit them. Done.

B2B Specification Inquiries

Are all fabrications done in Ireland?

Yes. All of our custom aluminium window cills, wall cappings, and flashings are fabricated, folded, and powder-coated directly in our Dublin fabrication workshop. This guarantees rapid lead times and direct line communication with our fabrication engineers.

Can I get site measurements before ordering?

Yes. While the Cills app is designed for builders to measure reveals on site using guided 3D prompts, we also provide a full "Measure, Make, and Fit" service. You can book a site measurement visit, and our technicians will record the exact dimensions for production.

How do I order in high commercial volumes?

For main contractors, commercial developers, and quantity surveyors handling large developments, we offer direct volume quotation channels, dedicated account support, and CAD/spec sheet integration. Get in touch via our Contact page for commercial terms.

What alloys and coatings are certified?

Every product is fabricated from premium 2.0mm marine-grade aluminium (alloy 5005 or 1050), specifically selected for high wind loads and salt-spray resistance. Our powder coating is done in-house using architectural-grade PPC powders oven-cured at 200°C to ensure UV stability.

// Core Principle

"Aluminium does not forgive guessing. Once it is made, it is made. That is not a warning. It is the reason we built Cills.ie."

Cills.ie — Measure. Make. Fit.
