Procurement & compliance

Specification across aluminium budgets

We don’t have a default range — we specify the best fit for the project. Cortizo, Smart Systems, and Aluprof are all fabricated in-house at our Slough workshop. System choice depends on the budget envelope, sightline requirement, thermal target, and the specifics of the elevation.

We’re trained and tooled on all three system houses. We routinely cross-specify between them — recommending the optimal system within the budget rather than pushing the most expensive.
