A warehouse or factory roof in Vientiane or the Savannakhet economic zone usually needs about 5 – 10% of its area in translucent skylight sheets to work by daylight. Santiago skylight sheets are glass-fibre reinforced composite in flat, 6-wave and 11-wave profiles; clear sheets pass up to 80 – 90% of daylight.
How many sheets per roof?
Roughly one skylight sheet in every 10 – 20 roof sheets, spread evenly in a chequer pattern rather than one long strip. A strip concentrates heat and glare in one aisle.
Even daylight under skylight sheets
Clear, white or blue?
| Colour | Light | Best for |
|---|---|---|
| Clear | Most light, up to 80 – 90% | Warehouses, loading areas |
| White | Softer, less glare | Workshops, packing lines |
| Blue | Softer, cooler look | Offices, canteens |
Will it fit my existing roof?
The skylight sheet must lap with the sheet next to it. The 11-wave skylight sheet has 20 mm ribs and the 6-wave has 28 mm ribs. Send the profile of your roof sheets so Santiago can confirm the match.
