Project Planning

Buying from a new window factory is a trust decision, and a sample or trial order is the cheapest way to test it. This guide covers what a window sample from China should prove, the difference between a corner sample and a full-size unit, what to inspect on arrival, how to vet a factory before you commit, how large a first order should be, what five-step quality control means for your batch, and which documents and payment terms protect your money.

Windows for Caribbean and coastal US projects are specified in a different order from inland work: approval first, then corrosion, then glazing and freight. This guide covers what Miami-Dade approval tests, how salt air attacks frames and hardware, how to choose between aluminium and uPVC, what to state in a wind load and water penetration specification, the documents your permitter, insurer and customs broker will ask for, and how to ship glazed units safely to island sites.

Importing windows and doors from China saves money only when specification, compliance, freight and payment are handled in the right order. This guide follows the full import process: writing a specification that returns a comparable quotation, MOQ and sampling, the certification documents your permit or insurer will ask for, production inspection, packing and sea freight terms, customs clearance and duties, and how to pay a Chinese supplier safely.

Aluminium doors deliver slim sightlines, high strength and long service life, making them the preferred choice for large openings and modern facades. This guide covers every aluminium door type — sliding, hinged, bi-fold, lift and slide and pivot — plus thermal break technology, glazing and hardware, finish options and the certifications (AS2047, NZS4211, Miami-Dade) buyers should verify. It also explains how aluminium compares with uPVC and what to check when sourcing custom aluminium doors.

Ordering custom windows and doors starts with a single set of numbers, and getting them wrong is the most expensive mistake in the project. This guide explains the three sizes every buyer needs to understand — the rough opening, the finished frame size and the installation gap — then shows how to measure each one, what clearances to leave for uPVC and aluminium, and which figure to send the factory when you order. Measure once, order right, install without surprises.

Window prices in 2026 vary widely because every custom unit is built to order, but the cost is driven by a small, predictable set of factors. This guide explains how uPVC and aluminium window pricing works: frame material, glazing, hardware, size and wind-load rating, certification (AS2047, NZS4211), and quantity. It compares uPVC versus aluminium lifetime costs, decodes quotations, MOQ and shipping, and shows what to prepare for an accurate custom window quote.
