A dedicated division of Sitim Software

Software built for
fenestration.

Specialist software for the window, door and glazing trade — engineered by a team that's lived and breathed the industry. Home of FramesHub.

Why fenestration

We didn't discover fenestration from a spreadsheet.

Years inside the industry taught us where it hurts — disconnected systems, endless rekeying, quoting that takes longer than it should, and software that solves one step without talking to the next.

The result was FramesHub. Today we're investing in a specialist software capability built for this trade and no other.

One industry. One connected chain.

Every link in the process — joined up.

Most software stops at the edge of one business. We build for the whole chain, so information moves with the job instead of being typed in again at every handover.
