What makes Cills.ie different from a standard fabricator?

We do not simply bend metal to a sketch. We provide a complete ordering system with block-specific details, live 3D validation, and detailed preparation sheets. This ensures a perfect fit for your finished render.

Are your window cills supply only?

Yes. All Cills.ie products are supply only. We focus entirely on engineering and manufacturing precision cills, leaving the fitting to your specialist on-site teams.

Positioning & Category Design

Why Cills.ie, A Category of One

We do not compete. We define. Sized to the finished render, backed by engineering data, and designed for the reality of modern Irish building envelopes.

We are not competing with other fabricators because we are not doing what other fabricators do.

Traditional sheet metal shops require you to supply your own drawings. They expect you to guess the dimensions and hope the bends match your wall profile. If your sketch is slightly off, the cills will not fit.

Aluminium does not forgive guessing.

Cills.ie is a category of one. We offer made-to-measure aluminium cills engineered specifically for Insulated Concrete Form builds. Every order is sized precisely to the finished render. You do not send a rough hand-drawn sketch. Instead, you select your exact ICF block brand, view the drawing, and see the exact specifications update in real time.

"Not a sketch. Not an assumption. The real thing."

The Fitter-First Customer Experience

See the Live Drawing

Verify every dimension visually on screen. No guessing how the upstand or drip edge relates to the block outline.

Get Your Spec Sheet

Every order comes with a detailed preparation guide for your site crew. We provide the information they need to prepare the openings correctly.

Publicly Improved Detail

Our design does not sit in a drawer. It improves in public. When fitters find a better way to route the DPC or handle the weep holes, we build it into the template.
