Fenestration
is broken.

Disconnected systems. Orders re-typed by hand. Deposits chased for weeks. Nobody knows what's coming next. It costs the trade money — and its reputation. FramesHub connects the whole chain back together.

A real system that works.

A real sale around the coffee table — the quote built live on the tablet, then sent straight to the factory as a real production order. That's FramesHub.
The problem

You already know how this goes.

The people aren't the problem. The disconnect between them is — and everyone in the chain pays for it.

The order gets re-typed at the factory — and something's wrong.

Fitter and factory blame each other. The customer just waits.

Deposits chased for weeks. Cash flow on a knife-edge.

No idea what's coming next week. Production is guesswork.

Remakes, delays, and profit quietly leaking at every handover.

The homeowner's left in the dark — and fenestration gets the blame.

Sound familiar? It doesn't have to.

The fix

One connected chain. End to end.

A doorstep survey becomes a real production order. The factory builds it — no re-keying, no queries. Everyone gets paid on time. And for the first time, the whole chain can see itself.

Stronger together — and hard to break.

The more of the chain that joins, the more valuable it becomes for everyone on it — and the harder it is to go back. Whichever part of the trade you're in, get in at the start.

The value

Is it worth it?

Every re-keyed order, every remake, every chased deposit, every week of guesswork — it all costs you, in money, time and trust. FramesHub is built to give it back. It doesn't add another system to wrestle with; it removes the gaps between the ones you already have.

Priced to make sense — for everyone in the chain.

A glimpse

We're not showing everything. Yet.

One survey. Two outputs — the customer's quote and the factory's spec, generated together. There's a lot more under the hood.

The team

Built by people who've lived the problem.

Sitim began as a software company delivering global solutions — design to implementation. Its senior partner had spent years in fenestration before that, and knew exactly where the industry breaks.

"I came back to the industry after a few years away — and found that nothing had changed. The same disconnects, the same waste, the same 'that's just how it's done.' That was the moment I knew it had to be built."— Tim, Senior Partner

So a group of partners came together — best placed to design, program and build a system that covers every attribute of the industry. Between them they bring decades from:

Automotive manufacturing Security software Banking Communications Fenestration worldwide

Experience drawn from the UK, America, Japan, Germany and France.

We know the industry is inflexible, and that the software thrown at it has too often made things harder, not easier — longer waits, more friction. And expecting a window company or factory to carry an IT department is unrealistic; the cost alone rules it out. So FramesHub takes those headaches away — truly automated systems that quietly do the work, removing the reliance on management teams forever fighting to keep afloat against a flood of issues.

Our strongest motive: not to promise what never gets delivered — the very thing others have tried, and failed, to do. This is a solution that works, built over the past three years, and now in its final testing.
"Not a pipe dream — a reality. An industry in need of change, but gentle change, where the benefits far outweigh the fear."
