The factory

One site, one quality gate. Sashes leave the line factory-assembled and pre-glazed — the tolerance work is done under a roof, not on your job site.

The section, up close

Every system is built on multi-chamber 6063-T5 extrusion with a continuous PA66 thermal-break bar and two replaceable EPDM gasket lines. The values in the performance band on the home page are read off this section — here it is, photographed.

Materials, specified at the line

Every material below is stated on the data sheet per project — the mill certificate for the profile, the schedule for the coating, the specification for the glass. Nothing is “equivalent or better” in the paperwork; the paperwork names the material.

Profile

6063-T5 multi-chamber extrusion, PA66-GF25 thermal-break bar, corner-bonded in the press line. Mill certificate retained per heat.

Surface

Chromate-free pre-treatment, 80–100 µm powder coat with the salt-fog schedule on coastal elevations, anodising or wood-grain film where the specification calls for them.

Glazing

Tempered, laminated or IGU to the project schedule — 0.38 SGP interlayer on impact units, 24–42 mm asymmetric laminated core on the acoustic range.

Hardware & seals

316 stainless on marine schedules, 6–12 point multi-point locks, anti-lift cam on every sash, two replaceable EPDM gasket lines with the replacement cycle published.

Six stages, one gate

  1. 01

    Extrusion & thermal break

    Multi-chamber 6063-T5 profiles; insulated bar joined and bonded in the press line.

  2. 02

    Finishing

    Anodising, powder-coating or wood-grain film; salt-fog schedule for coastal projects.

  3. 03

    Glazing

    Tempering, laminating and IGU assembly on site; acoustic and low-E schedules per specification.

  4. 04

    Sash assembly

    Factory-assembled sashes with hardware, gaskets and screens fitted and function-checked.

  5. 05

    Quality gate

    Dimensional audit, air/water/cycle spot tests and photo record before crating.

  6. 06

    Crating & loading

    Corner-protected crates, desiccant, loading report per container.

The quality gate, in numbers

Spot-tested on the rig at stage five, and the tested figure — not the nominal one — is what lands in the data sheet. Configuration targets as published on the home page.

What every crate documents

The balance of payment runs against a photo report, and the report runs against the same documentation that ships in the crate. Nothing on site should be guessed.

Packing list & loading report

Unit-by-unit, per container, with the crate and pallet map.

Pre-shipment photo report

Every unit photographed at the quality gate before the balance is due.

Hardware & glass schedules

The exact lock set, hinge line and glazing unit per reference — matches the schedule.

Install guide per market

The three-zone fixing detail and sealant schedule for your building code.

Crating

Corner-protected, desiccanted, with a moisture card at the first layer.

What a buyer should verify — and where we show it

The list below is what we would ask of a supplier. Each row names the document we issue against it, so the audit takes a checklist, not a conversation.

“Is the profile the one on the data sheet?”

Mill certificate per heat, attached to the shop drawings.

“Is the coating schedule specified, not assumed?”

Coating data sheet with the salt-fog hours for your elevation, per project.

“Is the glass unit built to the schedule?”

Glazing schedule per reference — thickness, core, SGP, low-E — matched against the quotation.

“Was the rating tested on our sizes?”

Project test report (PGT for impact, EN/AS rig for performance) on the configuration we ship.

“Does the documentation follow the container?”

Packing list, loading report and pre-shipment photo report — the balance runs against them.
