Common download questions

Are these the complete installation instructions?

The linked PDFs are the manufacturer’s documents. Our website guides help with planning and ordering; they do not replace the full installation instructions or the installer’s project-specific checks.

Why do the measuring references differ?

Some products use internal kerb dimensions and others use external upstand dimensions. Always use the relevant product’s drawing rather than transferring measurements between ranges.

I have an older rooflight. Which guide should I use?

Contact us with the product name, order reference and photographs of its labels. Do not assume the current-generation PDF applies to an older unit.

PDF copies saved 24 October 2026. Manufacturer documents can be revised; confirm the applicable edition for the unit supplied.
