Hill country house at dusk, full-height aluminum glazing

Global brands.
Built where each line is built best.

Meridian is not an importer of someone else's windows. We are a manufacturer — our specifications, our extrusion, our glass, our aluminum, our hardware, our powder coat — building across a controlled network of three plants: our own, plus two partner plants selected for what each one does best, with our team on site at every one. Australian aluminum. German thermal breaks. Dutch powder coat. British hardware.

Premium Aluminum · Distributor Program
The Range

Windows, doors and sliding systems. One matching system.

Aluminum windows and doors specified across Horizon, Ascent and Summit — from smart-value production systems up to NFRC-certified high-performance builds. All fully custom, all built to your architect's dimensions.

The Collections

Priced for the project, engineered for the code.

The core window and door lines are offered across the three tiers — so the same architectural detail can be specified for a semi-custom volume build, a luxury custom home client, or a certified California project. Same catalog, same dealer, three thermal packages.

The Meridian Standard

The details competitors don't talk about.

Where cheap-import windows fail your dealers is in the details you can't see from the outside. Here's what makes ours different — the reasons your customers will call you back for the next house.

01

Honest, duty-paid origin

Every container ships with full US duty paid and an accurate country-of-origin declaration. Nothing transshipped, nothing misdeclared, nothing under-declared — the story you tell your architect stands up to any tariff audit.

02

All-tempered, code-first glass

Every lite is tempered. Every unit meets U ≤ 0.40 / SHGC ≤ 0.25 with argon-filled, Low-E insulating glass as standard. No annealed-glass surprises on the safety-glazing walk-through.

03

Custom to the millimeter

Every unit is made to the opening, not picked off a size chart. Width and height to the millimeter across all three tiers, with shop drawings approved and signed before production is booked.

04

Our own specification, end to end

We are not reselling someone else's window. The extrusion, the glass, the thermal break, the hardware and the powder coat are specified by Meridian and built to those specifications at every plant we use.

05

Certified where it counts

Summit is tested to NFRC 100 and NFRC 200 by an accredited independent laboratory and listed in the Certified Products Directory. The CPD number prints on the quotation line, so a plan checker can verify it without calling us.

06

Warehouse pickup, dealer-friendly

Product staged in San Antonio, Houston, and Chandler, AZ for direct dealer pickup. No hidden freight, no last-mile surprises. Your truck, or we can arrange delivery.*

* Delivery charge applies. Product held beyond a few days from receipt is subject to storage.

How the program works →
