Specifying aluminium systems is high-value and detail-critical. Mistakes at the specification stage can be disastrous, potentially resulting in costly delays, site rework, compliance issues and fractured client relationships.
The complexity of modern projects seems to increase every year. Stricter building regulations and higher thermal performance expectations can make specifying more challenging. A wider range of systems and configurations might also make it harder to choose the right systems. This only emphasises the importance of getting it right the first time.
BDC Aluminium are a technical partner, not just a supplier. We’re here to help you specify the best products for your projects.
Incorrect Measuring & Specification Errors
Incorrect measuring and specification errors are common and frequently costly issues in the supply chain. Typical mistakes include incorrect aperture measurements, not accounting for tolerances, ignoring build-ups (like floor finishes, plaster and insulation) and miscommunication between the parties involved.
This could result in ill-fitting frames, on-site delays and additional fabrication or replacement costs. Coordination between all stakeholders is pivotal to the smooth running of projects.
Choosing the Wrong System for the Project
Not all aluminium systems are suitable for every application. In some cases, systems aren’t designed for the required spans or loads. Using residential systems in commercial settings (or vice versa) can cause issues. Or specifying the incorrect door type for the functionality needed, like choosing between bifolds or sliders, can prove problematic.
When specifying, make sure to consider the project type: whether it’s residential, commercial or mixed-use. Consider their frequency of use and the traffic volume they’ll experience. If you’re unsure, our expert team will help guide you through the system selection.
Thermal Performance Misunderstandings
There is increasing pressure to meet Part L and other energy efficiency targets. Common misunderstandings include misinterpreting U-values, assuming all systems perform equally, and failing to account for glazing specifications.
Wrong decisions can jeopardise compliance, lead to costly redesigns, and reduce performance.
Installation Issues
Even correct specifications can fail with poor installation. Incorrect tolerances on site, poor alignment and levelling, inadequate sealing and weatherproofing or lack of coordination with other trades could lead to callbacks and reputational damage.
As such, the importance of following manufacturer guidelines, using experienced installers, and conducting proper pre-installation checks is emphasised.
Specification Mistakes & Solutions Guide
You’ll find a helpful guide below, ideal for installers and specifiers as a practical reference.
| Common Mistake | Risk Created | Recommended Fix |
|---|---|---|
| Incorrect aperture measurements | Poorly-fitting frames, site delays | Conduct accurate surveys and allow tolerances |
| Ignoring structural requirements | Frame failure or poor performance | Confirm load requirements early |
| Specifying the wrong system type | Reduced functionality, client dissatisfaction | Match system to usage and project type |
| Misunderstanding U-values | Failure to meet building regs | Verify whole-unit performance and glazing specs |
| Poor communication between stakeholders | Errors, delays | Ensure clear documentation and coordination |
