Images and performance values are reproduced from the catalog. Please confirm configuration, test conditions and suitability.

Choose thermal-break windows for your project

Start with the opening style, opening dimensions and project requirements, then compare glazing, hardware and profile specifications. A model number alone does not establish whole-window performance or suitability.

What should Nigeria and Australia projects confirm?

Projects in Nigeria

Provide the project city, building type, floor level, orientation and opening drawings. Specify shading, ventilation, insect-screen, glazing and finish requirements. For coastal locations, identify the exposure and corrosion-protection requirements for review by the project team.

Projects in Australia

Provide the state or territory, climate zone and the whole-window U-value, SHGC, wind-pressure and safety-glazing requirements specified by your project team. Catalog figures are not proof of local compliance. Before ordering, review test documentation for the proposed configuration and the project's approval requirements.

What information is needed for a quotation?

Send the project country and city, window IDs, opening width and height in millimetres, quantities, opening directions, glazing requirements, interior and exterior finishes, screen and hardware options, delivery location and target schedule. Use ‘Enquire about this design’ to include your selected model, or ‘Send drawings’ to submit a schedule. Confirm packaging, transport, installation responsibilities and timing in the quotation.

How should catalog performance figures be read?

Read performance figures together with the relevant specification, glazing, dimensions and test conditions. A hardware brand, profile thickness or thermal break alone does not prove a particular acoustic rating, thermal rating or local certification. Confirm optional configurations separately; they are not automatically included as standard.
