The Ultimate
Metal-Building Insulation Solution
The Isover Factorylite Insulation, combined with the Ashgrid Spacer System, delivers a complete solution, engineered for energy efficiency, fire safety, and regulatory compliance.
When insulating metal buildings, performance, compliance, and safety are non-negotiable.
Thermal Compliance: SANS 10400-XA
For metal buildings, SANS 10400-XA requires insulation systems( like Isover Factorylite with Ashgrid) to deliver the correct R-values per energy zone, be installed properly without compression, and maintain continuous thermal performance. Non-compliance can lead to regulatory offences and refusal of building approval.
• Energy efficiency compliance: Metal buildings must meet the minimum thermal resistance( R-values) prescribed in SANS 10400-XA. These vary by energy zone across South Africa.
• Insulation thickness: The required thickness depends on the insulation type, density, and thermal conductivity. For example, Isover Factorylite Glasswool is designed to achieve compliance across multiple zones when installed at the correct thickness.
• Continuous thermal performance: Insulation must be installed without gaps or compression. Systems like the Ashgrid Spacer System help maintain full insulation thickness in metal roofs and walls, eliminating thermal bridges.
• Approved materials: Only insulation materials that meet the prescribed R-values and installation standards are compliant. Substituting with inferior products does not meet SANS 10400-XA requirements and constitutes a material deviation.
Isover Factorylite, working together with the Ashgrid Spacer System, delivers consistent thermal performance – cutting energy costs while ensuring full compliance with SANS 10400 XA across diverse energy zones.
Fire Safety: SANS 53501-1 & SANS 10400-T
For metal buildings, SANS 53501-1 requires insulation to be tested and classified for fire performance. Isover Factorylite, with its A1 / A2 ratings, provides non-combustible safety, ensuring compliance with SANS 10400-T and suitability for high-risk industrial and commercial applications.
• As of January 2025, insulation materials must be tested under SANS 53501-1. Isover Factorylite is already compliant.
• Only non-combustible insulation( A1 or A2) should be used in high-risk occupancies such as industrial plants, storage facilities, and plant rooms.
• Combustible insulation( B – F) is restricted and generally not permitted in buildings exceeding two storeys, depending on occupancy type.
• Isover Factorylite Glasswool achieves A-rated classification, meeting the standard and protecting your investment.
• Combined with the Ashgrid Spacer System, Factorylite maintains its fire performance while preventing compression and ensuring correct installation.
• Safe for high-risk occupancies such as industrial plants, storage facilities, and plant rooms.
Installation confidence
• The Ashgrid Spacer System is designed to simplify installation in metal buildings, ensuring Factorylite recovers to full thickness and performs as specified.
• Proper sequencing and installation guarantee compliance with both SANS 10400-XA and SANS 10400-T.
• Substituting Factorylite with reflective foils or coatings? That’ s a material deviation under SANS 10400-A – and an offence.
