Walk-on Rooflights in Llandaff — common questions

How strong is a walk-on rooflight?

Each unit is structurally calculated for its size and use — domestic units are rated for foot traffic with generous safety factors, and higher load classes cover planters, furniture and pavement-level duty. Strength is engineered per panel, not assumed.

Are walk-on rooflights slippery when wet?

Untreated glass can be, so we offer anti-slip finishes: a near-invisible ceramic frit pattern for light use, or sandblasted bands where the panel sits in a main walking route.

Can a walk-on rooflight go in my roof terrace?

That's the classic application — a flush glass panel set into the terrace deck, lighting the room beneath. The kerb takes the load and the perimeter drains with the rest of the terrace.

Do walk-on units lose much light versus normal rooflights?

Slightly — the thicker laminated build and any anti-slip finish reduce transmission a little. Below a panel in open sky, the difference rarely registers in practice.

Do you cover Llandaff for installation?

Yes — Llandaff is inside our standard Cardiff coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Llandaff on dedicated glass transport.

What's the lead time for Llandaff?

Stocked standard sizes typically deliver to Llandaff within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
