FAQ
What thickness do I need for a roof?
In hot climates 30 mm is the most common roof thickness; 40–50 mm improves comfort and cuts air-conditioning use. Purlin spacing (about 1.50 m) and wind load define the final thickness.
How far apart should the purlins be?
Roughly every 1.50 m. At panel end-laps a double purlin is recommended for firm support and to prevent leaks.
Is it better than corrugated metal?
It costs more per m², but removes the need for a ceiling, cuts indoor heat and power bills, and does not rust prematurely.
