Specifying Aluminium: How to communicate materials with your Irish contractor
Navigating Material Specifications with Builders
When you are talking to a general builder or sub-contractor about your extension, you might notice different pronunciations of key materials. While North Americans say aluminum (ah-LOO-min-um), in Ireland and the UK, the standard term is aluminium (al-yoo-MIN-ee-um). Misunderstandings in specs can lead to ordering delays or incorrect materials arriving on-site. Here is how to ensure clear communication.
The Technical Specification Checklist
To ensure your builder and fabricator understand exactly what you want, always specify the following details in writing:
- Alloy Grade: For architectural details (like cills or flashings), request grade 1050 or 3103 for sheeting, and grade 6063 for extrusions.
- Thickness: Don't just say 'capping.' Specify the thickness (e.g. 1.5mm, 2.0mm, or 3.0mm) to ensure structural stability.
- Finishing Standard: Always request polyester powder coating (PPC) to Qualicoat standards, specifying the RAL color code.
Why Written Specs Protect Homeowners
Using the correct local term aluminium in your contract and specification sheets ensures that local suppliers can quote accurately. Writing down the exact dimensions and finishes protects you if a contractor attempts to install lower-grade materials or standard PVC alternatives.
