Understanding how aluminium casement windows are made can help buyers appreciate the quality and technology behind their investment.
1. Extruding the Aluminium
Raw aluminium billets are heated and pushed through a die to create long profiles with precise cross-sections tailored for window frames.
2. Inserting Thermal Breaks
To prevent heat transfer, polyamide strips are inserted between the inner and outer aluminium profiles, significantly improving insulation.
3. Powder Coating
The aluminium profiles are cleaned, pre-treated, and powder-coated in a controlled environment. This process ensures a durable, weather-resistant finish available in numerous colors.
4. Fabrication
Profiles are cut to size, drilled, and machined for hardware fittings. Frames and sashes are assembled with precision to ensure smooth operation and tight seals.
5. Glazing
Double or triple-glazed units are fitted into the frames using high-quality gaskets and sealants to ensure airtightness and weather resistance.
6. Quality Control
Each window undergoes rigorous testing for water tightness, air permeability, wind resistance, and security compliance before leaving the factory.
