Factorylite is Built to Last in Gauteng Conditions
Factorylite Insulation is built to last, handling whatever Gauteng throws at it—here’s how it holds up:
- No Smell, No Trouble: It’s clean, odor-free, and plays nice with all standard building materials like wood or metal.
- Rust-Proof Protection: Won’t eat away at steel, copper, or aluminum—your roof stays corrosion-free for years.
