Understanding the cost of windows from China

Why there is no single window price

Custom windows are priced from a defined assembly and order scope. Opening dimensions, frame system, glass build-up, hardware and finish can all change the quotation. The proportion of fixed and operable units also matters.

This guide does not publish indicative prices because a figure without a matching specification can mislead a purchasing decision. Use your project schedule to request a current written quotation instead.

The product decisions that shape the quote

Start with opening style and frame construction, then specify the glazing and hardware. A fixed light and an operable sash of the same overall size do not have identical components. Special shapes, finish requirements or handling constraints can also change the scope.

• Opening type, panel arrangement and dimensions
• Aluminium system and thermal-break requirements
• Glass build-up, coatings and safety requirements
• Hardware, screens, finishes and accessories
• Quantity, packaging and any agreed inspection scope

Separate product cost from delivery cost

Ask the supplier to state the delivery term and its named place clearly. Identify which party arranges transport, insurance, clearance and unloading. A factory quotation and a delivered quotation should not be compared as if they include the same services.

Request a packing plan and shipment information before seeking a freight quotation. Your forwarder and local advisers should confirm destination charges and applicable import costs using the actual shipment details.

Build a like-for-like comparison

Create one row for each opening reference, then compare the specified system, glazing, hardware and quantity. Add separate rows for packaging, transport and other services. Record exclusions and assumptions beside each offer.

If a supplier proposes an alternative, ask for the difference to be identified explicitly. Do not accept a change simply because the product description still contains the words aluminium window or double glazing.

Request a project quotation

Send your destination, approximate quantities, opening schedule and drawings. If the specification is incomplete, identify which decisions still need discussion. A clear brief helps the supplier distinguish a preliminary allowance from a production-ready quotation.

Confirm quotation validity, payment stages, proposed production timing and change procedures directly with the supplier. These are order-specific commercial conditions and should be recorded in writing.
