Energy Savings
It helps reduce heat transfer through metal roofs, lowering indoor temperatures during hot South African summers while reducing heat loss in winter. This can significantly reduce heating and cooling costs over the life of the building.
Acoustic Performance
The fibrous glasswool structure absorbs sound energy and reduces reverberation, making Factorylite an excellent choice for warehouses, workshops and manufacturing facilities where machinery noise can be a concern.
Condensation Control
Metal roofs are prone to condensation when warm, moist indoor air meets a cold roof surface. The foil facing on Factorylite acts as a vapour barrier, helping to minimise condensation and protect the roof structure from moisture-related damage.
Fire Safety
Factorylite is manufactured from non-combustible glasswool and complies with relevant South African fire performance requirements, making it suitable for commercial and industrial buildings where fire safety is a key design consideration.
