Measuring Up: Ensure Your Roof Lantern Fits Perfectly
Ordering a roof lantern is exciting – but accurate measurements are key. Whether you're replacing an existing unit or cutting a new opening, here’s how to measure for a perfect fit.
Step 1: Internal vs External
Are your measurements based on internal ceiling space or external kerb dimensions? Stratus Lanterns are sized to external kerb dimensions.
Step 2: Measure the Kerb Opening
Measure the external edge-to-edge dimensions of your upstand or kerb. Note the width and length in millimetres or centimetres.
Step 3: Allow for Overhang
Most lanterns overhang the kerb by a small margin to ensure weatherproofing. Check with us if unsure – we’re happy to guide you.
Step 4: Choose the Style
From 2-way rectangular designs to square pyramid lanterns, your measurement may suit multiple styles. Our team can help you select the most suitable shape.
Final Tip:
When in doubt, always double-check. Or send us your roof plans – we can recommend the ideal Stratus Roof Lantern for your project.
