Best Price GuaranteeProfessional Industrial Glasswool Insulation for Commercial & Industrial Applications
When reliable thermal performance, fire safety and acoustic control are required, Isover Energylite Insulation is one of South Africa’s most trusted industrial insulation materials. Manufactured using lightweight glass mineral wool fibres bonded into flexible blankets, that provides excellent insulation performance while remaining easy to handle and install.
Unlike residential ceiling insulation, Energylite has been specifically developed for industrial environments where process temperatures, HVAC systems and mechanical services require long-term thermal protection.
Whether installed on air-conditioning ducting, chilled water pipes, hot water systems, industrial vessels or processing equipment, it helps minimise heat loss, improve energy efficiency and reduce operating costs.
Because glasswool contains millions of tiny trapped air pockets, it significantly slows heat transfer while simultaneously absorbing unwanted noise and vibration.
This combination makes Energylite one of the most versatile insulation products available for commercial buildings, factories, hospitals, shopping centres, hotels and industrial plants.

Frequently Asked Questions About Energylite Insulation
1. What is Energylite Insulation?
It is a flexible glasswool insulation blanket manufactured by Isover South Africa. It is designed for industrial and commercial thermal insulation applications including HVAC ducting, process piping, tanks, vessels and mechanical equipment. It provides excellent thermal efficiency, sound absorption and fire resistance.
2. What is Energylite made from?
Energylite is manufactured from fine glass mineral wool fibres bonded together to form a lightweight yet durable insulation blanket. The trapped air within the fibres provides excellent thermal insulation while also reducing noise transmission.
3. Where is Energylite commonly used?
Widely used for:
- HVAC duct insulation
- Air-conditioning systems
- Process piping
- Steam pipes
- Chilled water pipes
- Hot water services
- Industrial vessels
- Storage tanks
- Boilers
- Heat exchangers
- Manufacturing plants
- Commercial buildings
4. What thicknesses are available?
Energylite is commonly available in:
- 25mm
- 40mm
- 50mm
The correct thickness depends on the operating temperature and the required thermal performance.
5. What densities are available?
Isover Energylite is supplied in:
- 24kg/m³
- 47.5kg/m³
Higher-density insulation provides improved acoustic performance and greater resistance to compression in demanding industrial applications.
6. Is Energylite suitable for HVAC duct insulation?
Yes. it is one of the most widely used insulation materials for commercial HVAC systems because it reduces heat gain and heat loss while helping minimise condensation and improving overall system efficiency.
7. Can Energylite be used on hot water pipes?
Yes. it provides excellent thermal insulation for hot water piping systems and helps reduce heat loss, improving energy efficiency throughout the system.
